Common Ozzy by Tortoiseman
Ozzys (Osbourneidae) are a large family of nocturnal predatory bats found in the Americas, Russia, and coastal Antarctica. The average Ozzy measures in at 8 inches in length with a 2.5 foot wingspan. They have brown or a blue-black coloration similar to their ancestors, the Camazotz, which they share a similar morphology with.
Ozzys mostly eat bats, but they also eat rodents, small felines, and birds. They often hunt in packs known as "sabbaths". The pack communicates in very low frequencys to bypass the echolocation of other bats. The sabbath takes turns corralling the swarm of bats and grabbing bats with their large sharp teeth. They tear their prey's head off with their snout and chew the rest of the bat midair.
They patrol the air by using thermals which prevents them from having to flap their thick leathery wings and make noise while hunting. The only thing that stops them from flying completely silently is their thick coat of hair for cold nights.
A few notable Ozzys include Balcons, Arctic Ozzys, Finners, Urinators, and Arsonists. Balcons have a normal Ozzy morphology, however they hunt in a similar manner to falcons by diving onto their prey at a speed of 150 mph. Arctic Ozzys are two different genera on the opposite sides of the globe and they're exactly the same as normal Ozzys, but their polar environments warrant that they have a white coat for half of the year. Finners are a coastal species that hunts bats and seabirds, but they also frequently bite the fins off of sharks both dead and alive. Urinators do exactly what their name suggests, they urinate on bats midair to blind them so that they can get picked off easier. Arsonists take advantage of wildfires by grabbing burning sticks with their mouths and try and smoke their prey out.
