Korkusu

Behavior: Korkusu are incredibly hostile birds. From birth, they are forced to survive. Giving live birth to their young which they simply leave on the forest floor to fend for themselves, a vile temperament is developed early in these creatures. Serrated beaks and talons are the tools of these horrid thing's work as they swoop down on unsuspecting prey in flocks of 10 or more, savagely snapping and tearing at any exposed flesh until the victim succumbs to their onslaught, then the Korkusu land to begin their disgusting feast, fighting amongst themselves like unruly winged pigs over each and every scrap for their greedy gullets.

Details: Like most avians, Korkusu have distinct sexual differences. Males have a red crest upon their forehead and a bloated swaddle around their throat whereas females appear more dull and pale all over. Feathers of the Korkusu are so finely packed everywhere but their wings that they appear to be skin rather than plumage. Korkusu calls are absolutely horrid. Akin to the warbling of a klaxon siren mixed with the hooting of an owl.
