Ecology of Xema sabini

Main Ref.	SAUP Database, 2006
Remarks	Found on beach and shoreline (Ref. 116102). Coastal. Pelagic. Exhibits surface-seizing and plunge-diving behavior (Ref. 356). Opportunistic feeders. Feeds on small fish and small invertebrates, mainly crustaceans and insects; as well as faeces and carcasses. An arctic breeder; breeding area almost circumpolar with the exception of the Eurasian coast of Arctic Ocean. Nests on islets and flat, moist, grassy terrain of tundras, in pairs or small colonies. Often nests within colonies of Arctic terns (Sterna paradisaea). Common clutch size of 2 eggs. Migrates over oceanic waters southbound to western South America and south-southwestern Africa (Ref. 95138).
