Treść dostępna tylko w języku angielskim
The yellowhead or mohua; also known as bush canary) is a small insectivorous, passerine bird endemic to the South Island of New Zealand. Recent classification places this species and its close relative, the Whitehead, in the family Mohouidae.
The yellowhead and the whitehead have allopatric distributions as, conversely, the latter is found only in the North Island and several small islands surrounding it. Although abundant in the 19th century, particularly in beech forests from Nelson and the Marlborough Sounds to Southland and Stewart Island/Rakiura, they declined dramatically in the early 20th century due to the introduction of black rats and mustelids. Today they have vanished from nearly 75% of their former range. A quarter of the mohua population now lives in the beech forests of the Catlins area.
