Description

Habitat

Vegetation: freshwater marshes, saltwater and brackish marshes, coastal sand beaches and mudflats • Maximum Elevation: 1,000 meters • Foraging Strata: Water • Center of Abundance: Lower subtropical: lowlands, lower than 500 m.; subtropics. • Sensitivity to Disturbance: Medium

Typically found in a lake at a mean distance from sea level of 285 meters (935 feet).[1]

Ecology: Behaviour Most populations of this species are sedentary , although inland breeders will disperse short distances to the coast in the non-breeding season1, 2. The species breeds colonially1, 2, 3, from April-May (before the rains) in Africa2, and from early-May in South America1. It remains fairly gregarious outside of the breeding season2, 7, and is typically observed in pairs or small groups of 3-8 individuals7, or feeding in large flocks in harbours and at refuse dumps2. Habitat Breeding During the breeding season the species inhabits tropical and subtropical coasts, rocky offshore islands1, 2, coastal dykes , coastal dunes1, estuaries1, 2, 3 and harbours (Africa)1, 3, as well as large inland fresh and alkaline lakes (Africa)1, rivers1, 2, salt-pans5 and marshes (Argentina)1, 2. Non-breeding Outside of the breeding season the species remains along the shores of coastal habitats1 (e.g. rocky offshore islands1, 2, coastal dykes, coastal dunes1 and estuaries1, 2, 3) but also frequents settlements , cattle pens and fishing harbours (in Africa)1. Diet Its diet consists predominantly of fish1, 3, as well as invertebrates1 (e.g. insects, molluscs and termites)3, the eggs of herons and cormorants1, and dead fish and refuse obtained by scavenging1. Breeding site The species breeds colonially, with nests often placed less than 1 m apart1. Nests are positioned on bare ground , in clumps of reeds and papyrus1 on islands3, or on floating vegetation1, 3, often camouflaged in tall, thick vegetation3. The nest itself varies from a shallow scrape to a well built cup of rushes and grasses1, 3 depending on location, although floating nests are always substantial3.
