Corpsern

Corpsern - also known as corpse wyvern - is a particularly vicious subspecie of wyverns, causing many problems and deaths, while serving a quite important role of a scavenger, eating corpses of fallen beasts and creatures and generally not targetting mortals at all (unless they are already dead).
On the other hand... they dislike them coming too close to them, have deadly poison and sometimes cause plague outbreaks by digging out bodies (especially after battles, from shallow graves). Making them a notable problem for countries.

Basic Information

Anatomy

Two metres long reptiles clad in quite resistant scales and leather. Two legs at the back and two legs (fused with their leathery wings). Long mouth filled with sharp teeth. Scales and leather black.

Biological Traits

Particularly deadly venom capable of easily killing grown men in maybe a dozen minutes. There are antidotes, but to work they need a while and the poisoned person will still recuperate for a longer while.

Genetics and Reproduction

Corpserns have a mating season in summer. During eat males fight for the right to copulate with females which then lay 5 to 10 eggs, in most cases in or near their winter lair. After few weeks younglings hatch, very soon hunting for their own.

Ecology and Habitats

Corpserns are widespread especially in hotter climate - as reptiles they are coldblooded, meaning they prefer living in hot environment. While there are still some of them in the central-eastern Karathia (where they are still far less widespread than griffins), it is only because they can hibernate through winter.
They prefer lands with thriving megafauna and general wildlife, in most cases getting closer to settlements only when they lack food or there is too many of them.

Dietary Needs and Habits

Meat, especially of large herbivores and especially after them dying. Hunts by flying and then diving (with its claws at the front), preferably killing the target instantly and then devouring it. If not, it will proceed either to fighting on a ground, or retreats back to air, either to another dive attack or to retreat altogether and search for another prey.

Biological Cycle

Corpserns are surprisingly good diggers, capable of digging out lairs in soft ground when they hide (and hibernate) through the winter. When found they are easy to kill, on the other fact they mostly hide during the first snows meaning that it quickly covers their lairs, making it very hard to discover (not to mention that it mostly occurs in the far away places so that it isn't disturbed).
