Corvian Dweller

Mimicry: The corvian dweller can mimic simple sounds it has heard, such as a person whispering, a baby crying, or an animal chittering. A creature that hears the sounds can tell they are imitations with a successful DC 11 Wisdom (Insight) check.

Multiattack. The corvian dweller makes two attacks: one with its beak and one with its talons.

Beak. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 6 (1d8 + 2) piercing damage. 

Talons. Melee Weapon Attack: +4 to hit, reach 5 ft., 1 target. Hit: 7 (2d4 + 2) slashing damage. 

Wing Flutter. If the corvian dweller's speed isn't 0, and it is targeted by a melee attack, it flaps its wings in defense. It moves back 5 feet, causing the attack to miss if the corvian dweller leaves its range. This movement doesn't trigger opportunity attacks.
