Australian golden whistler

The Australian golden whistler (Pachycephala pectoralis) is a species of bird found in forest, woodland, mallee, mangrove and scrub in Australia (except the interior and most of the north) and in mountain forest in the Snow Mountains in the Papua Province of Indonesia. 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 in the golden whistler (one of the highest numbers of subspecies in any bird), while others treat several of these as separate species (as done here).
