White-Throated Robins are known from the Middle East in the Summer and Eastern Africa in the Winter 

Physical Description: White-Throated Robins are beautiful passerines that actually kind of resemble American Robins in coloration, though they are not closely related at all and this is simply a case of convergent evolution. They range in size between 15 and 17 centimeters long, with grey backs and short black tails. Their wings tend to end in darker grey wingtips. They have a white stripe over their eyes, with a black side of their faces. As the name would suggest, their throats tend to be white in color. They have short, very pointy beaks and long grey legs. The reasons for their name is the coloration of their bellies – most males are a dark red-orange, and the females are as well, but with brown spotting and more white color on their belly. Some males are more of a yellow color than red-orange, which is fascinating. The juveniles tend to look like the females, but more dull in color. 

Diet: White-Throated Robins primarily feed upon invertebrates and fruits, include a variety of beetles and ants, as well as berries. 

By John A. Thompson

Behavior: These robins will forage among the low twigs on the ground, as well as in  bushes and trees. They usually skulk around, spending most of their time in dense undergrowth and hiding in the thicket in order to avoid danger. They are very faithful to their preferred foraging sites, and will even defend them as their territory during the winter foraging season. They are highly migratory, wintering in eastern Africa – from Eritrea to Tanzania – and then leaving their winter sites by the end of March, passing through Kenya and Ethiopia through to Western Asia & Turkey, though some get as far west as Greece and some as far south as Israel. White-Throated Robins then stay in their breeding sites until the end of August, moving back to Africaq by going across the Middle East. 

Given this very noticeable migration, White-Throated Robins are extremely social and coordinated, making noticeable sounds to one another based on the situation at hand. Their songs are loud, vigorous warbling for multiple seconds with a variety of pauses and phrases, including flute-like whistling and scratchy chatters. These songs are often made in flight as well. Sometimes, the males of this species will mimic other birds. They also make warbles, hard “tec-tec-tec” calls, and more trilling calls as well. They can be, and usually are, extremely loud. 

White-Throated Robins tend to breed in dry, rocky slopes with some bushes provided for cover. They usually lay one brood per season, in a nest made of twigs and plant stalks and lined with feathers, usually made in the shape of a flat cup. They’re placed low to the ground in a tree, bush, or stump, and they often place their nests in the same sites from year to year. They lay between four and six pale green-blue eggs, with brown spotting. The eggs are incubated for two weeks, and the young stay for a little bit longer than a week within the next. They then can flutter around at two weeks of age, and fly fully at three weeks. They stick with the parents for another two weeks, before being fully independent.

Ecosystem: White-Throated Robins live in scrubland, steppe, stony arid hillsides, semi-desert, and mountainous regions during the breeding season, usually newer juniper and weedy terrain. They will also go to locations with birch and crab apple. In the winter they tend to live in semi-arid scrub and thickets, including acacia woodland and gardens. They don’t tend to reach higher elevations. White-Throated Robins are often preyed upon by lizards, snakes, and Common Magpies. 

Other: Funnily enough, despite being called a robin and being similar in appearance to the American Robin  – which is actually a thrush – White-Throated Robins are actually chats. Because passerine phylogenetics is a mess. They are not threatened with extinction, and there are probably millions of White-Throated Robins alive today.

First Described By: Brisson, 1760 

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoromorpha, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Avialae, Euavialae, Avebrevicauda, Pygostaylia, Ornithothoraces, Euornithes, Ornithuromorpha, Ornithurae, Neornithes, Neognathae, Neoaves, Inopinaves, Telluraves, Australaves, Eufalconimorphae, Psittacopasserae, Passeriformes, Eupasseres, Passeri, Euoscines, Corvides, Corvoidea, Corvidae, Corvinae

Status: Extinct – Extant, Endangered – Least Concern 

Time and Place: From 3.6 million years ago until today, from the Piacenzian of the Pliocene through the Holocene 

Magpies are known from all around the Northern Hemisphere 

Physical Description: Magpies are beautiful, if fairly recognizable Corvids, famed from all over the Northern Hemisphere for their cleverness and beautiful plumage. They can range in size from 43 to 60 centimeters long, with the Yellow-Billed Magpie reaching the smallest sizes and the Black-Billed reaching the largest. This makes them rather large as far as songbirds are concerned, though they are still significantly smaller than the Ravens and Crows that they’re close cousins to. Magpies tend to have black backs, heads, and necks, with varying levels of black on their bodies; they then have white bellies and white tops to their wings. The rest of their wings, and tails, can be black – or an iridescent mixture of colors on a black background. These colors vary from species to species, but can be blue, green, and purple-ish tinted – at least one species can even blend into the yellow-brown range. They have thick, strongly clawed toes; and they have very large, thick beaks, like other Corvids. They have short to medium sized wings as well, indicating their adapted ability for flying between and among thick trees.

Diet: Magpies are creative, opportunistic omnivores – they literally will eat anything. Insects, small vertebrates, eggs, carrion, leaves, fruit, seeds, your leftover pizza, that hamburger it found on the street, falafel, rice, a heaping load of spaghetti – literally, anything. It will eat anything. Hide your food. 

Behavior: Magpies are clever little buggers, with complex behaviors and extensive social communication. They tend to feed on the ground, usually with other Magpies, and even in mixed-species flocks depending on the abundance of food. They’ll Pick food up from the ground and dig into soil and litter, flipping over all sorts of things to look for food – including trash and poop. They’ll also hunt live food from perches in trees, or make traps to catch flies and other insects. Some will also stick around with predators and larger scavengers, looking for roadkill and other sources of meat that could be easily gotten from. They often will also store the food, in crevices and trees and the like, though usually they don’t leave the food for long and go to pick it up in a few days. The walk around and strut, usually fearlessly, attempting to catch whatever food they can; thousands of them can often be found foraging together, and using their unique cleverness to track down food.

Magpies are some of the smartest known animals – with large brain to body mass ratios, similar to those of cetaceans and primates; the region of their brains that works on cognitive tasks and higher thought processes is of a similar size to those found in chimpanzees and even close to those of people. As such, Magpies – much like their cousins the ravens – are some of the smartest animals alive today, probably holding second place after humans. They have high levels of social cognition, reasoning, flexibility, imagination, and ability to evaluate and predict the future. They also have very elaborate social rituals – they are able to recognize themselves, even in the mirror; and they show grief and rituals around the deaths of family members and friends. They also use tools, and use their experiences to predict the behavior of others. This knowledge of tool use is passed on from generation to generation, and modified as well – so they also have culture and rituals. They can count, imitate people, recognize words, and use tools to clean their own cages. They tend to form gangs in the wild, and use complex strategies in order to gather food and stick together. They also will ant – ie, apply ants to their plumage in order to prevent parasites and irritation – and sun-bathe to stay warm.

These birds roost communally and fly quite slowly over their ranges, usually interspersing their flaps with gliding to conserve energy. They make calls to flock members with regular frequency, mainly chattering and squeaking calls, as well as warbling songs and mimicry. Some species tend to have larger vocabularies than others, though they all make similar calls. Begging from the young sounds about as high pitched and peeping as one would expect. They have dominance hierarchies within the flocks formed during the non-breeding season, and dominant individuals in the flocks can and do steal food from the subordinate individuals. Interestingly enough, the younger males tend to dominate the older ones – though that may be more of a tolerance thing than anything else. These birds don’t tend to migrate, though they do move from place to place in response to climate and food availability. 

Black-Rumped Magpie

Magpies are monogamous, possibly staying with the same partner for their entire lives, and multiple sets of parents will work together to tend for the nests and care for the young. They start laying eggs in the winter, though usually most eggs are laid in the early spring. The parents will build the nests together, with the male bringing materials and the female doing the building. This usually takes a couple of weeks, and at the end the pair have a large domed structure made of sticks and twigs – a very deep cup, lined with soft wool, fur, grasses, and feathers. A fresh nest is built every year, even though the pairs stay together; they’re usually built in trees, usually near to the top, though buildings are sometimes used. Old nests are sometimes reused, if they were particularly good and lasted that whole time. They lay between two and nine eggs, though of course four to six is the most common number; and they are incubated mostly by the female for about two weeks. Both sexes will then feed the chicks, while the female does most of the watching and caring for them at the nest – leaving the male in charge of gathering the food and helping to fend off predators. Other pairs may come to help – usually relatives or friends. The young will leave the nest after a month to two months, and young in the nests may come together with other young – especially if there was a communal brooding situation – to form a creche of juveniles their own age. Honestly, it’s almost like a school class in some ways, with how they behave with each other and socialize and learn from the adults. They reach sexual maturity in about one to two years, and live for six years in the wild.

Speaking of friends – yes, magpies have been known to befriend humans, or at least have interactions with them. They are tame and friendly in areas where they’re left undisturbed, and in areas where they are shot at or bothered, they are defensive against humans coming into their areas. This can vary wildly, as they used to be considered viable game birds, but today they aren’t hunted as much and tend to be a little less on guard. They defend their nests violently against humans, and do not abandon them except as a last resort. Parents will mob people looking in on the nests – even scientists – especially if they are repeat offenders. But, since they recognize people’s faces, they are able to tell friend from foe (or perceived foe) and will seek out humans who give them treats or protection. 

Asir Magpie by Mansur Al Fahad

Ecosystem: Magpies stick to woodland and forests, though they do venture into more suburban and developed areas depending on the availability of trees. They will also inhabit open country, so long as there are some scattered trees available. Magpies can be found in all sorts of elevations, including in the mountains and as high as 4400 meters up into them. Some species, such as the Yellow-Billed, can tolerate warmer temperatures than others. Those that encroach on human habitat are often considered pests. While they do have predators, most are killed by West-Nile virus, to which they are particularly susceptible.

Other: Magpies are Corvids, so they’re cousins with all the other ridiculously smart passerine birds, making the question of “are members of the genus Corvus or the genus Pica smarter” rather one of splitting hairs. In the end, both genera showcase extreme intelligence, and are either the second smartest animals or close to it. Honestly, if they were smarter than humans I wouldn’t be surprised – they show culture and the ability to pass down learned things from generation to generation, and they might just be smart enough to not fucking destroy the planet (unlike us). Anyways, Magpies are often thought of as pests for their ability to get at sources of human food and also steal the eggs of birds with more pretty songs, so birders actually hate them. However, they don’t actually have a negative impact on the song-bird population. Most Magpies aren’t threatened with extinction and have populations in the thousands, though the Yellow-Billed species is vulnerable due to poisons used to take care of squirrels, and the Asir species is endangered due to a restricted range and decreasing suitable habitat.

Species Differences: The different species of Magpie differ primarily on coloration and range, as their sizes tend to be very similar. The Eurasian Magpie is often synonymized with the Oriental and Black-Rumped Magpies; whether or not these are three different species of bird is a bit of a taxonomical question. These birds range all over Eurasia – as the name suggests – with the “Oriental” subspecies (species?) being found more in Eastern Asia, and the Black-Rumped subspecies (species?) also found in Eastern Asia. At least a few varieties have a purple tail and dark blue wings; while others are more green on both the wing and tail, with only the tail tip coming out as purple. Asir Magpies are the only Magpies known from Saudi Arabia; they have dark blue wings and brownish tails, which end in a purple tip. The Maghreb Magpie is known from Northwestern Africa, and has a complete rainbow-colored tail and blue wings. The Yellow-Billed Magpie is especially distinct from the rest in having a yellow bill and yellow patches around the eyes (while the other species have black bills and black patches); they have blue wings and blueish-purple tails, and are found in California. Finally, the Black-Billed Magpie is found in the rest of North America (though not the eastern portion of the continent, or the southern), and has blue wings and a rainbow tail. There is one extinct species, P. mourerae, from the Pliocene of Spain; it seems to be very similar to living species except for that it wasn’t as good of a flier – and it may have even be flightless, due to the fact that it lived on an island!

Pelagornis

By Ripley Cook

Etymology: Sea Bird

First Described By: Lartet, 1857 

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoromorpha, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Avialae, Euavialae, Avebrevicauda, Pygostaylia, Ornithothoraces, Euornithes, Ornithuromorpha, Ornithurae, Neornithes, Neognathae, Pelagornithidae  

Referred Species: P. chilensis, P. longirostris, P. mauretanicus, P. miocaenus, P. orri, P. sandersi, P. stirtoni, P. tenuirostris, P. wetmorei 

Status: Extinct

Time and Place: Between 30 and 2.5 million years ago, from the Rupelian of the Oligocene through the beginning of the Pleistocene (in the Gelasian age) 

Pelagornis, being an extremely common seabird, is known from nearly everywhere around the world, usually associated with the coast. 

Physical Description: Despite the incredibly generic name, Pelagornis was quite an interesting bird. Like other pseudotooth birds, both its upper and lower beak bore toothlike spikes, in an alternating small/big/small/big pattern. Its beak was robust and fairly long compared to the back of the skull. These pseudoteeth appear to have grown in relatively late in Pelagornis’s growth, implying the keratin covering the beak may not have been fully hardened until close to adulthood. Interestingly enough, fossil evidence indicates that Pelagornis probably held its head upright at a vertical angle. 

By José Carlos Cortés

Pelagornis was fucking huge, m’kay. P. sandersi has an estimated wingspan between 6.1 and 7.4 meters! This makes Pelagornis the bird with the largest wingspan (but not the heaviest flying bird – that record belongs to Argentavis). Its wings were even more proportionally long and narrow than those of the largest flying birds alive today, the albatrosses. In comparison, its body was fairly small. There were, of course, some species of Pelagornis that were smaller than this, reaching only 4 meters long in terms of wingspan. Still, this large wingspan size is really only characteristic of these birds in flight – compressed, they would have looked much smaller, especially given that they were very light weight. They had stout legs and shorter tails, which indicates that they weren’t very good walkers, and spent most of their time in the air or sitting on the land. 

By Jack Wood

Diet: Probably fish. The pseudoteeth are likely an adaptation to grab and hold onto large fish. Similar toothlike serrations are seen, albeit much less exaggerated, in modern mergansers, which also eat fish. In addition, the vertical position of the head would have allowed Pelagornis to skim-feed, grabbing fish and other aquatic organisms from the top layer of the ocean and scooping them into their mouths. Thus, the fake-teeth would have allowed Pelagornis to grab onto fish better than non-toothed skim feeding birds. It may have also used these sharp fake teeth in order to grab onto the slipperiest fish and cephalopods – rather than harder shelly animals. 

By Scott Reid

Behavior: As with modern seabirds, Pelagornis likely spent most of its time out at sea. Gliding on oceanic thermals would have helped to support its huge body in the air without wasting energy just to stay aloft – which was important, since it wasn’t very good at flapping its wings and would have had trouble staying aloft long enough to get food if it had to flap too frequently. Think an albatross, but a giant, evil albatross. Landing and taking off would have been more awkward, though. It probably needed to take advantage of headwinds, drops in elevation and/or air gusts to get into the air at all. Albatrosses also kinda have this problem, but nowhere near to the same extent. The late appearance of the pseudoteeth implies that Pelagornis may have fed its young back on land like many modern seabirds before they could feed themselves out at sea. As such, they would have sought out good nesting sites, which may correspond to where fossils of Pelagornis are found – indicating that their spread around the world was greater than that we know of. Since it was a sea bird, it probably would have been very social, living in large colonies – and it would have cared for its young in similar social groups. In fact, it seems more likely than not that it would have laid its nests on cliffs and in rocky areas and plateaus, where being able to take off would have been easier than flatter, sandier beaches. Whether or not these animals were as noisy as modern seabirds is really another question altogether. 

By Jack Wood

Interestingly enough, Pelagornis had a salt gland in the eye that would have allowed it to excrete excess salt, which was an extremely helpful trait when Pelagornis ate almost entirely seafood. That seafood diet didn’t meant it wasn’t a danger, however – today, seabirds will venture away from the coasts in order to scavenge food on the beach, and they are certainly defensive of their nests, young, and territory. Also fascinatingly, it had a very very very long skull – with all of those pseudoteeth packed in – which had similar shapes and organization as to the extinct really toothed birds of the Mesozoic. This implies that there was a certain amount of evolutionary regression in Pelagornis, allowing it to better support its teeth and chomping ability than it would otherwise. There is also an interesting furrow in the skull, which allowed it to be better support the head and possibly to better grab prey in the ocean. 

By Scott Reid

Ecosystem: Pelagornis lived around coastlines worldwide. Because of this, it is difficult to pinpoint with certainty the types of animals it lived with. In fact, it was so long-lived and widespread it is more likely than not that Pelgaornis interacted with any ocean-going creature or animal found along the coast. It doesn’t seem to have a preference in the fossil record between rocky coasts or beaches, though it did seem to stay in at least somewhat warmer ecosystems and where cliffs would have been present for easier take-offs (and it is reasonable to suppose that cliff areas would have been its preferred place for nesting). Some notable animals it would have interacted with include extinct penguins, cetaceans, the famed giant shark Megalodon and… humans. Yup, Pelagornis is known from locations where early members of genus Homo ventured to. So, if you can imagine being afraid of a giant bird with fake teeth a little too well, that would be the instincts of your ancestors talking. 

By Scott Reid

Other: Pelagornis is a fun time, classification wise, for multiple reasons: one, a whole bunch of different types of Pseudotoothed birds are actually, apparently, species of Pelagornis; and two, we don’t really know what Pseudotoothed birds really are. So, let’s break this down into those two parts. What’s going on with the species? Well, in the 2010s, a lot of research has been made that shows a bunch of the Neogene Pseudotoothed birds that we’ve counted as different genera are actually… just… part of Pelagornis. Why Wikipedia has not chosen to update their information as to this effect is beyond me, but the fact remains is that a lot of Pseudotoothed birds are just different shades of Pelagornis, primarily due to the fact that they really… aren’t different. In fact, a lot of the differences were just based on time and place, and the fact that Pseudotoothed birds weren’t really well known at all. The loss of Osteodontornis is a bit of a bummer, but there aren’t any major differences between this genus and Pelagornis, so it’s gone. We’ve also lost Pseudodontornis, you know, the name that actually means “fake toothed bird”, unlike the crappy name for Pelagornis, which just means Sea Bird. Like, come on people. Why are we here. Just to suffer. We’ve also lost Palaeochenoides, Neodontornis, and Tympanonesiotes. Hence the extreme amount of art in this article – the last time I covered Pseudotoothed birds, these were separate. So we have an abundance of terrifying tooth art. 

By José Carlos Cortés

Finally – what the heck are Pseudotoothed birds? We don’t know. We really don’t know where they go. Are they related to the sea birds we have today (the Aequorlitornithes)? Are they related to ducks? Are they something else entirely? We have no idea, because, frankly, they seem to just appear in the fossil record without any sort of origin whatsoever. Like magic. Suddenly, toothed birds were back like the asteroid never hit. Honestly if I were to hazard a guess, based on the fossil characteristics, they’re probably none of the above – but an early branching group of Neognathous (aka, all birds that aren’t ratites and their cousins) birds that evolved from a non-easily fossilized ancestor. Whether that ancestor had weak bones or just lived in places where fossils don’t happen is a different question entirely, but either way, so far we have nothing. They just appear, in the Paleocene, out of nowhere. And, eventually, Pelagornis also disappeared. 

By Jack Wood

Why did Pelagornis, the latest surviving species disappear? The most likely answer is climate change. The onset of the ice age would have caused extreme changes to the water patterns, currents, and air flow. Since Pelagornis didn’t flap its wings much, and relied almost entirely on soaring and thermals, it probably would have been greatly affected by changes in these weather patterns. So, changes in the ocean and the air by the ice age would have decreased its ability to reach food, and then the dramatic changes in its home climate would have been a further death knell. Interestingly enough, they only began to become uncommon right before they became extinct – indicating that Pelagornis really was finished off by this change in climate. Which is sad, because that’s right around when humans were becoming more of a thing, and it would have been nice to see one of these things in life. Except it wouldn’t have been. Because they’re terrifying. But I laugh in the face of danger. I think. I dunno I just think they’re neat. 

By Scott Reid

Species Differences: The different species of Pelagornis differ primarily due to location and time, though there are some differences in shape and size – those fossils that were once assigned to Tympanonesiotes, for example, were on average smaller than other members of this genus. The largest known species was decidedly Pelagornis sandersi, though the best known species is Pelagornis chilensis. For now, however, Pelagornis is kind of a mess, since so much research is needed on this species complex to make sure things are where they belong and one genus is enough, so species differences are difficult to parse out until more research has been published on the subject. Just know that there were a lot of Pelagornis – and they came in all kinds of different shapes and sizes all over the place.

Balaeniceps rex

Etymology: Whale Head

First Described By: Gould, 1850 

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoromorpha, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Avialae, Euavialae, Avebrevicauda, Pygostaylia, Ornithothoraces, Euornithes, Ornithuromorpha, Ornithurae, Neornithes, Neognathae, Neoaves, Aequorlitornithes, Ardeae, Aequornithes, Pelecaniformes, Balaenicipitidae

The Shoebill is known from eastern central Africa 

Physical Description: There is no other dinosaur quite like the Shoebill. It is one of the most visually distinctive creatures, with traits monstrous and familiar that make it difficult to really understand exactly what you’re looking at. They stand up to 140 centimeters in height, which yes, is the height of a human being on the shorter side. They can even reach 152 centimeters tall – the same height as a 5 foot tall person. They have very long, skinny legs, with giant toes on their feet that are widely splayed out. Their bodies are huge, with short tails and bulky torsos. Their backs are grey, and their belly feathers are white. Their necks are a lighter grey, and there is some dark speckling all over their wings and right beneath their necks. Their heads continue that light grey coloration, and have small tufts of feathers as a crest on the back of the head. Shoebills also happen to feature yellow, unblinking, perfectly circular eyes, which is unsettling at best. They have heavy eyebrows of feathers over their eyes, giving them a look like they’re always glaring at you – which is even more disconcerting considering the giant, wide, scoop-shaped bill that the Shoebill is named for. The bill is orange, and ends in a small hook, just in case you weren’t terrified enough. 

By Peter Halasz, CC BY-SA 2.5

Diet: Shoebills feed mainly on fish – especially lungfish, though most large fish are acceptable. Amphibians, young crocodilians, water snakes, rodents, and young waterfowl are also fed upon by these giant terrifying creatures. 

By Snowmanradio, CC BY-SA 2.0

Behavior: Shoebills are calculating bastards – they’ll hover around lakesides and swamps with low oxygen in the water, which forces lungfish to come up to breathe – so that the Shoebill can then lean down and scoop them up. They are loners during the hunt, carefully taking each step as they make sure to not sink too far into the mud and weeds where they live. Their lunging after food is hard to miss – their mouths open wide, revealing how huge those bills really are, and giving it a sinister smile. These lunges are usually startling, as the Shoebill is usually still for a very long time before it goes after prey. It is as if a statue had suddenly come to life. This is especially disconcerting when the Shoebill opts for standing on floating vegetation – just casually going down with the current as though they were a giant Jacana. They tend to defend territories for food, at least somewhat, not coming closer than twenty meters to another Shoebill during feeding. They don’t sense their prey with feel, but entirely by sight – making them very unblinking and focused, adding to their strange aura. Shoebills are also usually silent, which just makes their entire aesthetic even more terrifying. When they do dare to make sounds, they make very raucous cries – usually while they fly.

By Petr Simon

Yes, yes they can fly. Shoebills are some of the largest flighted birds today, which does not help. They hold their wings flat, pulling in their necks to their bodies to aid in making their flight more efficient. They have some of the slowest flaps of any bird, at 150 flaps per minute. They fly only a few meters at a time, and usually prefer to glide as much as possible. The farthest any Shoebill as traveled at one time seems to be 20 meters. As such, Shoebills are not very mobile birds, and they usually only move from place to place based on food availability.

By African Parks/Bengweulu Wetlands Photography

Shoebills begin breeding depending on the water levels of their habitat at a given time. They lay their eggs when the rains begin to end and the waters start to recede; as such, the chicks hatch and fledge late in the dry season. They nest alone, though there are possible reports that they may form some breeding colonies in South Sudan. They make nests out of grass in a mound that is three meters wide, usually placed on a small island or on floating vegetation amongst dense papyrus. They lay two eggs that are incubated for a month. The chickare cute, fluffy, and grey, with tiny regular sized bills. They then fledge a little more than three months later and, what’s more, usually only one chick survives. The chicks and parents will make whining and mewing to each other to get attention and beg for food. Sometimes, the young will make hiccups as begging calls. The parents are constantly with the young for the first forty days of rearing, only briefly leaving to get food and water or nest material. As the chicks age, the parents spend more and more time away, but they still bring food regularly. The chicks, after fledging, remain dependent on the parents for food for a few more years. They reach reproductive age at around three to four years. Displays often including mooing and bill clattering, which can be accompanied by the shaking of the head from side to side, which is quite the undertaking for a bird with such a large head. Breeding pairs stay together for the season, and break up when the chicks leave the nest. Shoebills can live up to fifty years, which is aided by the fact that they tend to not have predators after reaching full size.

Ecosystem: Shoebills stick to marshes, especially papyrus marshes and those with reeds and cattails. They will also gather around marshy lakesides, especially near Lake Victoria. They go wherever they can find floating vegetation to stand upon, including ricefields. They tend to go where animals such as hippopotamus go, since the hippo can dredge up food that the Shoebill can then feed upon. 

By Fritz Geller-Grimm, CC BY-SA 2.5

Other: Shoebills are currently considered vulnerable to extinction, with 5000 to 8000 birds thought to be remaining in the wild (though that may be low and there may be as many as 10,000). The reasons for this decline in population is partially due to habitat loss – the Shoebill is dependent on papyrus swamps and other wetland habitats, which are targeted by drainage schemes and other development activities. Animals being brought across these swamps and trampling their young also majorly contributes to population decline. It is a very unique bird and a very popular one, so luckily there are some conservation efforts ongoing, especially in zoos. Some hunting is also contributing to population loss. Despite these conservation efforts, only once has the Shoebill been successfully bred in captivity.

Magpie Shrikes are known mainly from Southern Africa, though some are in Tanzania, and they do not extend as far as the farthest south of Africa 

Physical Description: Magpie Shrikes are extremely distinctive birds, with small, squat bodies and ridiculously long tails. They are black all over, except for white stripes across the wings and on the sides of their bodies. The tails are very long, thin, and black. The males and females mainly differ in that the females have shorter tails than the males – other than that, they look nearly identical. They have short, squat heads and tiny pointed beaks. The males can range between 22.5 and 35 centimeters long, and the females can be between 21 and 33 centimeters long. Young Magpie Shrikes tend to be more brown. 

Diet: These birds feed on a wide variety of bugs and other arthropods, including ants, termites, grasshoppers, mantises, millipedes, and grubs – as well as lizards, mice, rotting meat, and even fruit!

Behavior: Magpie Shrikes are strange little birds which spends a lot of time swooping down from small trees and bushes, dropping down to the prey and grasping it tightly to catch it. They do this alone, swooping down dramatically – sometimes from as high as 20 meters in the air – in order to find food. On the ground they can and do forage in large groups. They will attack their prey rather viciously – stabbing with their beaks, creating bloody messes in the process. It will also snatch food from the air from time to time. They are very noisy birds, making a variety of complex sounds to one another – reflecting their complicated social structure. Included in these calls are loud, repeated whistles indicating territory that sound almost like “needle boom needle boom”; the breeding pair “teeloo” duets; scolding alarms of “chack chack chack” against ground predators; alarm calls against predators coming towards the nest; and begging calls are loud repeating buzzing sounds. They don’t tend to migrate, but do move in response to fires clearing habitat. 

Generally social, Magpie Shrikes breed in the rainy season, usually in monogamous pairs that work together with groups during the breeding season to ensure the best chance of survival for the main pair’s chicks. The breeding pair build the nest together with helpers bringing them materials; this nest is made of a cup from trigs, fibres, and grass. They make these nests about 4 meters above the ground in a thorny tree – they prefer acacia – and they tend to lay between 1 and 6 eggs. These eggs are incubated by the females, while the males bring them food, until they hatch between two and three weeks later. The helpers and parents then feed the chicks together – and, tif there are two broods, the older siblings of the second brood take part in the feeding of the chicks. The young start to forage for themselves after two weeks, but they stick with their parents and are sometimes cared for by them for up to eight weeks.

By Bernard Dupont, CC BY-SA 2.0

Ecosystem: Magpie Shrikes live in savanna and open woodland, usually with very sparse acacia trees scattering the habitat. They also can be found in moister habitats, and also semi-desert areas. They can be found in parks, suburbs, and even active cities from time to time. They are predated on by crows, monkeys, humans, and birds of prey. 

Other: Magpie Shrikes are, thankfully, not threatened with extinction – though they are rare in places heavily modified by people, but some are found in extensive suburban and even somewhat urban locations.

Hoopoes are known from all over the Eastern Hemisphere 

Physical Description: Hoopoes are extremely distinctive birds! They have very long, thin, and curved bills that extend out greatly from their heads, and huge crests on their heads that are easily spotted. They have long, thin bodies, and feet built for perching. Their wings are very square-ish, and they have shorter tails than other birds. However, their coloration is decidedly where they are most distinctive of all. They have bright orange heads, with orange crests – but the crests end in very slight white bandings and then black tips. Their bodies are orange, but their wings and rumps and tails are black and white striped all over! They are such beautiful, distinctive birds. The shades of orange can differ in brightness or redness based on species (for example, the African Hoopoe tends to be redder than the Eurasian Hoopoe), but they do tend to be overall similar to one another in appearance. Living species range between 19 and 32 centimeters long; the extinct Saint Helena Hoopoe, though it had smaller wings, probably could have reached 36 centimeters long. 

Madagascan Hoopoe by Charles J. Sharp, CC BY-SA 4.0

Diet: Hoopoes primarily feed on insects, especially larvae, though some larger animals are also fed upon by these animals. 

Common Hoopoe by Charles J. Sharp, CC BY-SA 4.0

Behavior: Hoopoes are very curious, adventurous birds, spending a lot of their time foraginging on the ground – they’ll dig with their bills into soft earth, using them to turn over leaves and probing into the mud and dung for insects and other invertebrates. They’ll even use their bills to prise off the bark from trees, or forage for insects in lichen! Sometimes, these birds also smash their food against the ground to They’ll usually forage in pairs or alone, spending a lot of their days looking for food. Some Hoopoes – especially the Madagascan Hoopoe – will forage in even slightly larger groups, of up to six individuals. Fascinatingly, Hoopoes have their own version of Penicillin – Anting! They’ll find piles of ants and roll around in them, allowing the ants to cover their feathers. The ants then secret substances that will kill bacteria, fungi, and other insects – protecting the Hoopoe (and other birds that Ant) from illness! These birds also take dust and sand baths to clean themselves; they’ll also sunbathe by spreading out their wings and tail low to the ground and tilting their heads up! 

Madagascan Hoopoe by Charles J. Sharp, CC By-SA 4.0

Hoopoes are distinctive in one very special way that lead to its name – their voice! They literally make calls that sounds like “hoo-poo-poo” and “hoop-oop hoop-oop” – leading to the name, Hoopoe, as well as the genus  name, Upupa, and the species name of the Eurasian species, epops. Interestingly enough, the Madagascan Hoopoe does not make this sound – but rather, more cooing sounds, like doves. These birds will also make harsh, scolding calls, trills, and hisses, depending on the situation. The females and males will communicate primarily in trilling sounds while watching out for their nests. These birds are often sedentary, not migrating over long distance, but northern populations usually do come south in the winter to avoid colder climates, creating a variety of populations with very distinctive seasons and migrational patterns from one another within the species. 

Saint Helena Hoopoe by Apokryltaros, CC BY 2.5

Hoopoes are monogamous each breeding season (which varies throughout the year as Hoopoes live all over the Eastern Hemisphere), forming strong pair bonds (that only last for that period of time). Males make very frequent calls to establish their territories, and they often fight with each other very brutally – including stabbings that can leave their opponents blinded. Females will then mate with the winners of these contests, and together they make nests out of holes in trees and walls with very narrow entrances. They usually aren’t lined with much. The female then incubates the egg, while the male defends her and the nest. Clutch size tends to depend on location, varying between 4 and 12 eggs per nest. They are incubated for nearly three weeks. At hatching, the chicks are very white and fluffy after a few days, and the crest develops after two weeks. The chicks are able to leave the nest after about a month, though they still stick with their families for a little while. Sometimes, when males defeat each other and replace each other in the mated pair, they will kill the offspring of the replaced male. Females can produce foul-smelling liquid, as do the babies, to protect themselves from predators – since they smell like rotting meat, they can fend off meat-eaters and parasites, and potentially fend off bacteria. Chicks in the nests also are able to literally poop at intruders, helping them to protect themselves! After leaving the nest, they stay with the parents for another week as they gain their bearings; they then become sexually mature between ages one and two. 

Eurasian Hoopoe by Frank Vassen, CC BY 2.0

Ecosystem: Hoopoes live mainly in open country – pastures, orchards, steppe, dry savanna, wooded savanna, short grassland, and bare ground. They congregate near scattered, isolated trees for their roosting and nesting. They do need perches and shade, but they want the trees they get these services from to be rare in the environments – so they can go down to the ground to get their food! They are fed upon by herons, falcons, and many other birds of prey. 

African Hoopoe by Derek Keats, CC By 2.0

Other: Most hoopoes are not currently threatened with extinction – they are extremely common, widespread birds, that are even protected in many localities (being highly venerated in many cultures – it’s even mentioned extensively in the Quaran – and made the national bird of Israel; it is also considered a pest controller and thus is protected on that front also. Some local populations, such as those in Morocco, are more threatened due to local practices (such as selling them for medicine), but overall they seem to be doing well. In fact, there are probably as many as 10 million Hoopoe around today, if not more. Still, in more northern countries such as Germany they are more endangered, primarily due to changes in habitat, hunting, and human activity giving pressure to the populations. The numbers in Madagascar are slightly vulnerable too, given forest clearance. Hoopoes are closely related to the Hornbills! 

Saint Helena Hoopoe by Scott Reid

Species Differences: The four species primarily differ based on location: The African Hoopoe is found in Africa; the Eurasian Hoopoe is found in Eurasia; the Madagascan Hoopoe is known from Madgascar: and the late Saint Helena Hoopoe – now extinct – was known from the island of Saint Helena off the coast of Africa! The Saint Helena Hoopoe differed from the other species in other ways, too – it had smaller wings, was somewhat larger, and was probably flightless! A giant flightless Hoopoe! And, like most large flightless birds of the recent past, it went extinct due to human activity on the island – this time, sometime in the 1500s.

Cyanochen cyanoptera

By Brent Moore, CC BY 2.0

Etymology: Dark Blue Goose 

First Described By: Bonaparte, 1856 

Classification: Dinosauromorpha, Dinosauriformes, Dracohors, Dinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Avialae, Euavialae, Avebrevicauda, Pygostylia, Ornithothoraces, Euornithes, Ornithuromorpha, Ornithurae, Neornithes, Neognathae, Galloanserae, Anseriformes, Anseres, Anatoidea, Anatidae

The Blue-Winged Goose is only known from the Horn of Africa 

Physical Description: Blue-Winged Geese look very similar to other geese in terms of proportions – with round bodies, short tails, and long necks. Their heads are small, as in other geese, with small triangular bills. They also look like most non-canadian geese by being softer and rounder in general angles and shape. They differ from other geese primarily in color – they have grey heads and brown bodies, but the undersides of their wings are distinctively powder-blue in color, with black and green contrasting feathers around the blue. The males have brighter colors than the females, and are in general heavier – though they range between 60 and 75 centimeters in length in both sexes. The tails of these birds are usually black. The juveniles differ from adults in being duller in color still.  

By Dick Daniels, CC BY-SA 3.0

Diet: Blue-Winged Geese feed mainly on grasses, sedges, water-edge plants, and sometimes invertebrates. 

Behavior: Despite being geese – and even feeding on aquatic food from time to time – Blue-Winged Geese seldom swim! Instead, they will graze along the river bank, searching for food while keeping their feet firmly planted on dry land. They also mostly do this during the night, spending their days asleep! Even though it is reluctant to both swim and fly, it is good at both, but will rarely run away from humans approaching it. They are social birds, forming flocks year-round, which are filled with high-pitched whistles and penk-penk-penk calls. They do move flocks occasionally during different seasons – and go to higher altitudes during the dry winter to breed. 

By Charles J. Sharp, CC BY-SA 4.0

They begin breeding during the dry season, usually forming single pairs to build nests on the ground hidden by the vegetation. The female does most of the incubation alone, laying four to seven eggs and incubating them for about a month. The chicks hatch very fluffy and brown-black, taking around three months to fledge. They then join the flock, and become sexually mature at around two years of age. These flocks can include hundreds of geese, and are a noticeable feature in the Ethiopian landscape. 

Ecosystem: Blue-Winged Geese primarily live in grassy meadows and pastures at mid to high levels of elevation, usually near rivers and lakes and pools. It will avoid entering deep water, though it will venture into waterlogged soils with dense vegetation. 

Blue-winged Goose RWD2.jpg

Other: Blue-Winged Geese might be common, but they have a very unfortunately restricted range – which means there are probably less than 10,000 sexually mature individuals alive today, which are specially affected by drainage and habitat conversion by local populations. Luckily, local religious beliefs prevent it being hunted, however immigrants into Ethiopia are starting to hunt the Blue-Winged Geese which is causing increased pressure on this bird. Clearly, protection is needed and increased monitoring of its population. This is especially important as Blue-Winged Geese is actually a very unique bird – it’s not a goose at all, but a duck! It is closely related to Hartlaub’s Duck, another unique African species of waterfowl, indicating an isolated clade of African waterbirds evolved similarly to waterbirds around the world. More research is needed to better understand these birds – but they must be protected so we can do so.

The Gabar Goshawk is known from most of sub-Saharan Africa, apart from the densest rainforest 

Physical Description: Gabar Goshawks are small birds of prey, coming in two main morphs of colors – some are dark all over, with dark banding on their tails; while others are grey, with that same dark banding on its tail. The females are larger than the males, and they range between 28 and 36 centimeters long. Their feet have long claws and are orange, and they have short, curved beaks that are orange with black tips. So, in a lot of ways, they are somewhat Halloween themed birds of prey! The sexes tend to look the same. They also have white patches on their wings, most of the time. The juveniles tend to be brown, with streaks across their chests. 

Diet: Gabar Goshawks feed mainly on other birds! Primarily, small birds such as guineafowl, coucals, and francolins. They also eat small reptiles and some small mammals – including bats! 

Gabar Goshawk (Melierax gabar) (6487243123).jpg

By Bernard DuPont, CC By-SA 2.0

Behavior: The Gabar Goshawks will spend a decent amount of time actively pursuing prey, diving through the air to catch the flighted animals after which it chases. It will sometimes also wait in trees, or go into nests in order to get food – taking dozens of animals from sites at a time and bringing them back to their nests. It will hunt mainly in places of cover, sometimes in pairs, and sometimes with the help of falcons. They’ll tear into nests, grabbing whatever they can to devour the food inside. They are fairly silent birds, only making piping noises from perches when displaying to each other. These piping calls will also be made when feeding young – and when the young are asking for food. 

Gabar Goshawks don’t migrate, but they do tend to move locally based on the dry season, and juveniles are a little nomadic and move in response to food. They tend to lay eggs at the end of the dry season, sometimes even breeding twice a year. The couple will do circles in the air around each other, and call to each other as a part of their mating rituals. They build nests together out of sticks in thorny trees, using earth and rootlets to bind the nest together. These nests are usually quite high off of the ground, and they’ll even have intentional spiderwebs on top to conceal the eggs. Two eggs are usually laid, and incubated for a little more than a month by the female; the male will help bring her food. The chicks are very white and fluffy, growing less and less white as they age. They fledge after another month or so, and tend to become more independent at that point. 

Gabar Goshawk (Micronisus gabar) 1.jpg

By Lip Kee, CC BY-SA 2.0

Ecosystem: As indicated by their distribution, Gabar Goshawks live primarily in open thorn savannah and in some more open woodland habitats. They are preyed upon by tawny eagles, Wahlberg’s Eagle, and Ayres’ Hawk-Eagle. 

Other: Thankfully, Gabar Goshawks are not threatened with extinction. They are common and widespread in a grand variety of habitats. Their range is even expanding, and in recent years they’ve been found in new locations outside of their natural range. There are some places where they are scarce, but by and large they are very common. They are brave birds, colonizing urban areas, though they are sometimes hunted by people due to being perceived as a threat (though they’re too small to be a problem for poultry!)

The Bush Blackcap is known from South Africa and Swaziland 

Physical Description: Bush Blackcaps are small passerines with distinctive orange-pink bills, somewhat thick and slightly curved. They have black caps to their heads – hence the name – and white chins. These white feathers extend to the belly region, while the back of the bird is brown. The tail is somewhat long and also brown. They have small pink legs and feet. The sexes are all similar, and the juveniles are in general just a bit more dull than the parents. 

Diet: Bush Blackcaps feed mainly on berries, other fruit, and small invertebrates. 

Bush Blackcap 2016 12 30 15 33 23 2771 crop.jpg

By Alan Manson, CC BY 4.0

Behavior: These songbirds will forage alone, in mated pairs, and in small groups, usually moving quietly and carefully through the middle layer of the forest or in the scrub to grab food from off of foliage. They will also congregate around fishponds in the winter to gather water and food near the water’s edge. During the breeding season in the late spring and early summer, the males will make very beautiful complex songs with a variety of notes and tones. Both parents will build the nest out of twigs and grass, placed safely in a tree fork. They tend to lay between two and three eggs per season. They do not migrate much, but do move up and down the mountain level in response to the breeding seasons and food availability.  

Lioptilus nigricapillus -Giants Castle Game Reserve, KwaZulu-Natal, South Africa-8.jpg

By Alan Manson, CC BY-SA 2.0

Ecosystem: Bush Blackcaps live in temperate and mountain evergreen forests on slopes and near ravines and on the forest edge. They will occasionally go out into the bush, but not as much as their name would suggest! Their nests are parasitized by cuckoos. 

Other: These are vulnerable birds, due to extreme habitat loss – the forests are slowly decreasing in spread, and it is predicted that with the arrival of more extensive climate change, they will decrease in spread more. It seems as though the range of the Bush Blackcaps has already decreased by 30% by 2014, with more destruction of the habitat having occurred in recent years as well. Currently, there seem to only be a few thousand individuals of this species left.

Egyptian Vultures are known from locations across India, Western Asia, Africa, and Southern Europe 

Physical Description: The Egyptian Vulture is a small vulture, only about 54 to 70 centimeters long with a wingspan of a little more than twice that size. It is also very distinctive in color, and extremely fluffy (which makes sense, given it is probably closely related to the Bearded Vulture). It has a very long and narrow head, which is bare and yellow over the eyes and beak; the tip of the beak is sharply hooked and black. The back of the head and neck is very fluffy and white. The rest of the body is also very puffed, mostly white but with black edges and tips to the wing feathers and tail feathers. It has white fluffy legs, with only some of the feet bear; the feet are pale in color. The females are usually much heavier than the males. The juveniles are significantly darker than the adults in color. 

By Carlos Delgado, CC BY-SA 3.0

Diet: Egyptian Vultures primarily feed on large dead animals such as carrion of birds, livestock, wild mammals, and even dogs. Usually it will prefer scraps from large carcasses. Sometimes it will also eat eggs! 

By Вых Пыхманн, CC By-SA 3.0

Behavior: These vultures are pragmatic opportunists, eating a wide variety of carrion that are often rejected by other vulture. It even competes often with crows and other corvids – more pragmatic, intelligent birds! These vultures spend a lot of the day soaring overhead, searching for food from up to one kilometer away; they also will perch and search for food on trees and cliffs. They tend to congregate in large numbers where there is good sources of food – even though this bird is rare. They will pull off chunks of carcass and often will throw stones at eggs to open them up – a documented use of tools! They also will use twigs to roll up and gather strands of wool for nest-lining. They aren’t very loud birds, making small whistles, grunts, groans, and hisses when needed. Somewhat social birds, they are usually found in pairs or in large groups around carcasses, though often they spend time alone. 

By Jiel, CC BY-SA 4.0

Egyptian Vultures breed in the spring, with pairs courting by soaring high together and then swooping and spiraling down. They are monogamous for at least one breeding season, and may stay with the same mate for many years or even their whole lives. They tend to come back to the same nest sites year after year. They make nests out of twigs and wool, placed on cliff ledges and on large tree forks. Neighboring birds may form polyamorous groups with a mated pair, allowing for the two pairs of adults to aid each other in caring for the young. Usually the birds prepare for copulation by giving each other food, and preening each other to get in the “mood”. They lay around two eggs usually, which are incubated for around one and a half months. All adults will incubate the chicks, which are very brown and puffy. They stay in the nest for up to three months, cared for by the parents for most of that time. They reach sexual maturity between 4 and 6 years of age, and can live for nearly four decades, though most tend to die by the fifth year of life in the wild.

The vultures tend to soar on thermal wind, using the heat to raise themselves higher in the air; on the land they’re much less graceful, waddling around awkwardly. They are very calculating animals, waiting for predators to leave a carcass before approaching. They’ll even feed on poop to get carotenoids – pigments – from large herbivorous mammals. They tend to migrate only in the northern part of their range – in Africa and India, they stay mainly in the same location year-round. They glide extensively while flying, wasting as little energy while migrating as possible.

Ecosystem: Egyptian Vultures prefer open areas, preferably ones with dry and arid habitat. They especially prefer locations near cold and wet climates, such as scrub habitats. They also frequent deserts, steppes, pastures, and some fields, though they try to stay near rocky places when nesting. They also can be found in mountainous regions at lower or mid-level altitudes. They are hunted upon by golden eagles, eagle owls, and red foxes as young; they also are very vulnerable to other mammalian predators (like wolves) as adults and to human interference. In fact, human activity takes a toll on population size.

Other: Egyptian Vultures have gone through extensive population decline, though in some locations the population is more stable now and recovering. They are greatly affected by human activity, including things such as power lines and hunting, intentional poisoning, and superstition-based activity. Since vultures are considered harbingers of doom, people tend to be afraid of them – and they aren’t always the prettiest birds, so people don’t feel emotional attachment to them enough to avoid killing them. Declines in herding and livestock maintenance among humans also has lead to some population decline. Combinations of these factors in many countries make conservation efforts difficult to implement. Some attempts to preserve this vulture have included “vulture restaurants”, where carcasses are made available to vultures nearby.
