The long-legged flycatcher ( Petroica australis ), English name New Zealand Robin , māori Toutouwai , is a species of bird native to New Zealand . The long-legged flycatcher is classified as not endangered in the Red List of Threatened Species .
description
The long-leg flycatcher reaches a body length of 18 centimeters and a weight of 35 g. The legs are long and thin. The plumage of the male is dark slate gray, that of the female gray-brown. In both sexes, the throat and abdomen are considerably lighter and creamy white in the male.
distribution
The long-legged flycatcher is endemic to New Zealand . The birds are scattered on the South Island and Stewart Island , but have no closed range. On some islands, such as Ulva Island , it was released back into the wild after predators (e.g. cats, rats) were exterminated .
The species inhabits forest edges and is often found in the green belts of localities. The distribution area is estimated at 50,000 to 100,000 km².
Systematics
South Island Robin ( Petroica australis australis ) and Stewart Island Robin ( Petroica australis rakiura ) are now recognized as subspecies. The closely related North Island Robin (formerly Petroica australis longipes ) is considered a separate species according to studies by Miller & Lambert from 2006. Another closely related species is the Chatham flycatcher ( Petroica traversi ) on the Chatham Islands .
Differentiation of quantities
According to a study by researchers at Victoria University , free-living long-legged flycatchers can differentiate between different amounts of worms, see article Differentiation of amounts in animals , section Long-legged flycatchers .
