Kenku

Kenkus are a race of humanoid avians in Dungeons & Dragons with an extremely long history; they first appeared way back in the Fiend Folio in Advanced Dungeons & Dragons 1st edition! Possibly based on the Tengu of Japanese mythology, they have taken many different forms over different editions.   The original Kenku, as said above, first appeared in the Fiend Folio. Here, they appear as humanoid hawks, having the basic frame of a human, but with bird-like feet, clawed hands, hawk wings sprouting from their backs, feathers covering their skin, and the heads of hawks. They are mischievous, magical beings who have many innate abilities that they develop as they age; alongside random spell-like abilities, they develop the ability to shape-change into a human form, turn invisible, and call lightning. They are mischievous tricksters who love to mess with people, both for fun and for profit; deception, robbery and kidnapping are their favorite ways of funding themselves.   They were updated to 2nd edition in the Monstrous Compendium Volume Two, and subsequently reprinted in the Monstrous Manual; they were basically identical to their Fiend Folio depiction, but more cut-down. It was also mentioned that some humanoids kidnap kenku hatchlings and bring them up as slaves.
