Shibugarasu

was a demon bird that sought the Shikon no Tama.

Hisotry
It disguised itself using the corpse of a bandit leader in order to steal the Sacred jewel from Kagome. when Inuyasha appeared in the old shack and the lead warrior's armor slips, revealing the crow in his chest. It had eaten out his heart and was controlling him. Inuyasha tried to kill the crow but missed, and the crow swallowed the jewel and flies away. Kagome and Inuyasha start chasing the crow. Kagome tried to shoot the crow with an arrow, but missed. She hit it near a lake and its parts fell into the lake, but Kagome had forgotten that it had the jewel and it started to reform. It flew away again. A child started to scream that one of the crow's feet was on his back. Kagome grabbed it and tied it to an arrow. She then shot the arrow, hitting and killing the crow, but shattered the jewel into tiny shards.

Manga vs Anime

 * In the Manga, Shibugarasu turns into some sort of bat-winged reptile with a large mouth upon transforming, while in the anime he still looks like a bird. Also in the manga, the chase didn't take place near a river.
