The Grey-headed Gull (Chroicocephalus cirrocephalus) is a small gull which breeds patchily in South America and Africa south of the Sahara. It is not truly migratory, but is more widespread in winter. This species has occurred as a rare vagrant to North America and Spain. It is known as the Gray-hooded Gull by the American Ornithologists' Union. As is the case with many gulls, it has traditionally been placed in the genus Larus.
