Birds of Paradise

The birds of paradise (极楽鳥) are vicious demons that are the archenemy of the wolf-demon tribe. They live on top of a huge mountain which is their nest. They are led by a Siamese bird that has two Shikon jewel shards. They appear as large pigeon-like birds with harpie-like bodies from the waist-up jutting from their bodies.

Koga kidnaps Kagome for the main purpose of finding the bird of paradise that has a sacred jewel shard.

InuYasha's Tetsusaiga destroys a large number of the birds of paradise, and it is revealed in a conversation between Ginta and Hakkaku that all the birds had been killed, suggesting there was only the one nest to begin with.

Trivia
