\"Pigeon Guillemot,\" Wikipedia, the free encyclopedia.The Pigeon Guillemot (Cepphus columba) is a medium-sized alcid endemic to the Pacific. They closely resemble the other members of the genus Cepphus, particularly the Black Guillemot, which is slightly smaller.Adult birds have black bodies with a white wing patch broken by a black wedge, a thin dark bill and red legs and feet. They are similar in appearance to the Black Guillemot but show dark wing linings in flight. In winter, the upper parts are mottled grey and black and the underparts are white. They walk well and habitually have an upright posture.
