From Ardrana

The aarakocra are a race of intelligent bird-men that live on the peaks of the highest mountains, spending their days soaring on the thermal winds in peace and solitude.

Aarakocra are about 5 feet tall and have a wing span of 20 feet. About halfway along the edge of each wing is a hand with three human-sized fingers and an opposable thumb. An elongated fourth finger extends the length of the wing and locks in place for flying. Though the wing-hands cannot grasp during flight, they are nearly as useful as human hands when an aarakocra is on the ground and its wings are folded back. The wing muscles anchor in a bony chest plate that provides the Aarakocra with extra protection. The powerful legs end in four sharp talons that can unlock and fold back to reveal another pair of functional hands, also with three human-sized fingers and an opposable thumb. The hand bones, like the rest of an aarakocra's skeleton, are hollow and fragile.

Aarakocra faces resemble crosses between parrots and eagles. They have gray-black beaks, and black eyes set frontally in their heads that provide keen binocular vision. Plumage color varies from tribe to tribe, but generally males are red, orange, and yellow while females are brown and gray.

Note: Aarakocra originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
