Razorbill

The razorbill is a black-and-white seabird that nests in crowded colonies along North Atlantic coastlines. It's the last surviving member of its genus and the closest living relative of the extinct great auk. These birds dive underwater to catch fish, using their sharp, flattened beaks like tiny paddles.

• Razorbills are the only living species in their genus Alca.
• They nest in noisy cliffside colonies with other seabirds.
• Their closest relative was the flightless great auk, now extinct.
