Birdfolk

Whether Aarakocra, Owlin, or Kenku, birdfolk do not have parents or families. Instead, all birdfolk hatch from eggs in an enormous nest called The Aerie on the Plane of Elemental Air. Not much is known about this nest beyond what birdfolk remember from their childhoods, as no one from the outside has ever found it. Young birdfolk spend their first three years in the Aerie, learning to communicate and fly from their older nestmates. During this time, the fledglings build their skills by gathering baubles, trinkets, and tools from lesser djinn and other beings of elemental air, returning them to the stockpile in the nest
Once they reach maturity, they gather their portion of the treasure, spread their wings, and follow the great Westerly Wind, emerging somewhere in the skies of Arvor.
Legends say that birdfolk are the dead, reincarnated by chaotic deities without memory of their former life for one last chance to fulfill their destinies. Many birdfolk are strong believers in second chances, and tend to feel a restless wanderlust, eager to get on with their destiny. It may be for the best – they have remarkably short lifespans, living between 30 and 50 years.

Kenku are a special case among the birdfolk, burdened with a curse that robs them of their ability to fly, and in some cases their unique voice. Instead of riding the winds, Kenku are forced to climb down the cliffsides of The Aerie for ten years before emerging at the base of a mountain in the material plane. Kenku have found themselves at the base of mountains all across the world, without any clear path or view to the cliffs that lead back to The Aerie. Historians have collected numerous versions of this story, yet have been unable to establish any clear link between a physical location and their place of origin.
