• Alcid — A generic name given to seabirds of the Alcidae family (alcids), order Charadriiformes, distributed across the cold seas of the Northern Hemisphere (such as the auk, puffin, guillemot). They are birds excellently adapted structurally for pelagic life, featuring dense black-and-white plumage, short wings used as powerful underwater flippers, and the capacity to dive to great depths to fish.
