Variable oystercatcher

Variable oystercatcher (Haematopus unicolor) is a familiar stocky coastal bird with a long, bright orange bill, found around much of New Zealand.Breeding success of variable oystercatchers is often low, with main causes of failure being predation of eggs or chicks by a range of mammalian and avian predators, flooding of nests by big tides, and disturbance resulting from human recreational use of the coast.
