Chroicocephalus cirrocephalus (Grey-hooded Gull; Gray-hooded Gull)

Synonyms: Larus cirrocephalus

Wikipedia Abstract

The grey-headed gull (Chroicocephalus cirrocephalus), also known as the grey-hooded gull, 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. As is the case with many gulls, it has traditionally been placed in the genus Larus. Flocks numbering hundreds or thousands of these gulls can form when the feeding conditions are appropriate. In flight, the wings are broader and held flatter than those of black-headed gull.
