Aarakocra

Description
From below, aarakocra look much like large birds. Only when they descend to roost on a branch or walk across the ground does their humanoid appearance reveal itself. Standing upright, aarakocra might reach 5 feet tall, and they have long, narrow legs that taper to sharp talons.

Feathers cover their bodies. Their plumage typically denotes membership in a tribe. Males are brightly colored, with feathers of red, orange, or yellow. Females have more subdued colors, usually brown or gray. Their heads complete the avian appearance, being something like a parrot or eagle with distinct tribal variations.
