Natives to shadowfell, Kenku naturally have good dexterity, giving them an extra point to their dexterity score.

With black feathers and a voice capable of mimicking any sound, the Kenku are naturally able to deceive and move stealthily. Their avian heritage makes them perceptive.

Crow Kenku can mimic any language, though while they can speak common through this trait, they can also speak primordial, specifically the Auran dialect 

While the Kenku curse forces them to only speak in words they've heard before, they can also mimic any other sound, natural or unnatural, if they've heard it at least once before.
