Golden whistler
The Australian golden whistler (Pachycephala pectoralis ) or golden whistler, is a species of bird found in forest, woodland, mallee, mangrove and scrub in Australia (except the interior and most of the north) Most populations are resident, but some in south-eastern Australia migrate north during the winter. Its taxonomy is highly complex and remains a matter of dispute, with some authorities including as many as 59 subspecies of the golden whistler (one of the highest numbers of subspecies in any bird), while others treat several of these as separate species.
The male has a bright yellow underside and nape, olive-green back and wings, a black head and chest-band, and a white throat. A notable exception is the Norfolk golden whistler (P. p. xanthoprocta ) where the plumage of the male is female-like. In Australia females are overall dull brownish-grey, though some have yellowish undertail coverts. Both sexes have a black bill, dark legs and red-brown eyes.
Australian golden whistlers have a strong, musical voice.
The Australian golden whistler can be found in almost any wooded habitat, especially dense forests. It eats berries, insects, spiders, and other small arthropods. They usually feed alone and obtain food from the lower to middle tree level, or they may alternatively take part in mixed-species feeding flocks.
This species breeds between September and January. Male and female both work on the nest, which is a shallow bowl made of twigs, grass, and bark, and bound together with spider web. Only one brood is raised per season and both birds share incubation and care of young. Eggs hatch 15 days after they are laid and the young leave the nest after 12 days.
The Australian golden whistler is considered to be of least concern, and it is generally described as common to fairly common.
The Norfolk golden whistler (P. p. xanthoprocta ) declined for many years due to habitat loss and fragmentation and possibly also due to introduced predators such as the black rat. Most of the population is now restricted to the Norfolk Island National Park. This has resulted in it being listed as vulnerable by the Australian Government. Another island subspecies, the Lord Howe golden whistler (P. p. contempta ) remains common, but was listed as vulnerable by the Australian Government due to its small range. It is not listed anymore.
