Crowber

A Crowber, also known as a Crow , is a crow-like enemy first seen in New Super Mario Bros.. These enemies tend to appear in the last courses of the game, where they attack Mario or any other potential victim with rather fast moves. The name Crowber appears to be a pun from "crowbar," a tool used to remove nails.
