Clearing islands as refugia for black-fronted tern (Chlidonias albostriatus) breeding colonies in braided rivers
Black-fronted terns/tarapirohe (Chlidonias albostriatus) are highly adapted to nesting on clear shingle areas of the braided rivers in the South Island, New Zealand. They are nationally and internationally classified as endangered. Ongoing threats, primarily an interaction of predation and habitat degradation or loss, have resulted in population decline. Conservation management in the form of control of introduced mammalian predators has proven partially successful.
