Justification
Although this species may have a restricted range, it is not believed to approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be increasing, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is very large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

South Island Oystercatcher

The South Island oystercatcher or South Island pied oystercatcher (Haematopus finschi) is one of the two common oystercatchers found in New Zealand. Its name is often contracted to the acronym "SIPO" (rhyming with "typo").

Description[edit]

Easily identifiable as a pied oystercatcher – a large wader with striking black and white plumage, long red-orange bill and red legs. Distinguished from the pied morph of the variable oystercatcher by a white lower back, more white on the wing, and a demarcation line of black and white further forward on the breast. Distinguished from the pied oystercatcher of Australia by a longer bill and shorter legs, as well as the forward demarcation line of white on the back being pointed rather than square. Measurements: length 46 cm; wingspan 80–86 cm; weight 550 g.[2]

Distribution and habitat[edit]

The South Island oystercatcher is endemic to New Zealand where it breeds inland on the South Island, after which most of the population moves to estuaries and harbours on the North Island. It has been recorded occasionally as a vagrant on Norfolk Island, Lord Howe Island and the eastern coast of mainland Australia. Its breeding habitat comprises braided river systems, open paddocks and cultivated land, lake beaches, subalpine tundra and herbfields. Non-breeding habitat includes coastal estuaries, bays, beaches, sandflats and intertidal mudflats.[2]

Behaviour[edit]

Food[edit]

Mainly molluscs and worms.[2]

Voice[edit]

Piping calls, used socially and aggressively; also piercing alarm call and a quiet flight call.[2]

Breeding[edit]

Nests in sand scrapes on farmland or gravel banks in braided rivers. Clutch usually 2, sometimes 3, brown eggs, blotched dark and pale brown. Incubation period 24–28 days, with both sexes incubating. Young precocial and nidifugous; fledging 6 weeks after hatching.[2]

Conservation[edit]

The population of this species declined, mainly because of hunting, during the late 19th century and early 20th century but, with legal protection since 1940, has since been increasing. In 2002 the total population was estimated to be 110,000. Its conservation status is of Least Concern.[3]
