Voraxavid
Yet another species for my future evolution project.

While the skyjaegers became aerial predators, some seabirds became largely terrestrial predators. These were the voraxavids. They are descendants of giant petrels, which became more dependant on scavenging, but eventually broadened their diet to include more live prey, a change spurred by the large amount of new prey items emerging in Antarctica. They have well-developed wings, which are used in balance and for clubbing opponents in comabt, and they are still able to fly. Their main prey are tetrels, which they mostly hunt at night. Their well-developed eyesight and sense of smell allows them to pinpoint the location of their prey, before chasing it down, as tetrels are normally not very fast. They will also take their prey while it is inside its burrow, by putting its head down the tunnel and grasping the tetrel. To help keep hold of its prey and drag it out, voraxavids have sharp, backward-pointing papillae lining their tongue and roof of their mouth, which act like teeth, digging into the flesh and keeping hold of the prey no matter how hard it struggles.

Tetrels at Night
Another bird for future Antarctica. This one is foraging in the moonlight.

Some dimunitive, largely nocturnal, terrestrial birds found on Polycenic Antarctica are the tetrels, flightless descendants of Procellariiformes, specifically Procellaria. These small birds create burrows beneath the tussock plains, safe (mostly) from predators – sometimes, in colonial species, the tunnel systems can be quite extensive. Their burrowing adaptations are a defence against the avian predators, the voraxavids and the skyjaegers (see below). They can make their nests deep down under the earth, forming their tunnels using their clawed feet, compact body, and a flattened plate over the beak, used for pushing through soil. Tetrels are mostly nocturnal, emerging at night and using sensitive rictal bristles to forage for terrestrial invertebrates to eat.

Filtermew
A bird for my future evolution project.


Perhaps the most interesting animals on Polycenic Antarctica are the descendants of seabirds. It is not hard to see why they abandoned the ocean for the inland tussock plains – they offer shelter, food, and safe places to make nests under tussocks, safe from the prying eyes of predators.

Gulls were amongst the first birds to make the change – being highly adaptable, it didn't take long for some species to severe their ties with the ocean. This is an event that can be seen throughout the world as gulls diversify, but nowhere has it yet resulted in a form such as that seen on Antarctica. These creatures, known as filtermews, took advantage of the swarms of flying insects, and become aerial filter feeders. Early filtermews would fly through a swarm, mouth wide open, rictal bristles helping to trap the insects, like a net. However, more advanced forms also developed baleen-like papillae lining their tongue and the roof of their mouth, aided by sticky saliva – this helps to trap the flies and other insects inside the mouth while it is still moving, until it closes its mouth and uses its tongue to rasp off the trapped prey. This method of foraging is efficient, especially during the summer when there are huge amounts of insects. However, during the winter months, when flying insect activity is low, the filtermew birds are forced to broaden their diet and spend more time actively pecking around in search of food. They do particularly well at the end of the Polycene and on into future times, due to the arrival of mosquitos, good fodder for these birds.

Skyjaeger
This is a bird for my future evolution project: s1.zetaboards.com/Conceptual_E…
This is a skyjaeger, which lives in the future Antarctica

The skyjaegers are descendants of skuas, which have taken advantage of the new aerial prey presenting itself, from passerines to filtermews. They become faster and better fliers, able to ambush their prey in the air – however, instead of attacking with the feet like many birds of prey do, the skyjaegers using their sharp, serrated beak to stab into their avian prey. Many species of skyjaegers have highly keratinised faces, probably an adaptation for the rigours of hitting the prey face-first at high speed. Their long beaks are capable of killing prey instantly, then they can be passed down to the claws, to be carried to a safe place to eat.

I have been encouraging fellow paleoartists to create pieces of art inspired by my posts, so that they can be featured on my blog Mesozoic Musings. The response to my Pinacosaurus post has been amazing, so here's all of the posts so far on other people's art and my original idea.

Pinacosaurus: Long-tongued, Armoured Beast of the Cretaceous (original post): mesozoic-musings.blogspot.co.u…

Pinacosaurus: the Sequel: mesozoic-musings.blogspot.co.u…

Pinacosaurus Strikes Again: mesozoic-musings.blogspot.co.u…

Pinacosaurus the Fourth: mesozoic-musings.blogspot.co.u…

Thanks everybody who contributed, and for anybody else, the offer still stands!

Hii, just saw all the faves and the watch - thank you very much! I'm glad you like my stuff. All your (speculative) paleo and biology art is super cool, especially since you're just 14. That's very impressive :D
