Grey headed gull


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.

This locally abundant gull breeds in large colonies in reedbeds and marshes, and lays two or three eggs in a nest, which can be on the ground or floating. Like most gulls, it is highly gregarious in winter, both when feeding and in evening roosts. Although it is predominantly coastal or estuarine, it is not a pelagic species, and is rarely seen at sea far from land.

Flocks numbering hundreds or thousands of these gulls can form when the feeding conditions are appropriate.

The grey-headed gull is slightly larger than the black-headed gull at 42 cm length. The summer adult has a pale grey head, a grey body, darker in tone than the black-headed, and red bill and legs. The black tips to the primary wing feathers have conspicuous white "mirrors". The underwing is dark grey with black wingtips. The grey hood is lost in winter, leaving just dark streaks.

    In flight, the wings are broader and held flatter than those of black-headed gull.

    This is a noisy species, especially at colonies. The call is a raucous crow-like caw, caw.
