Louisiade whistler

The Louisiade whistler (Pachycephala collaris) is a species of bird in the family Pachycephalidae, which is endemic to the Louisiade Archipelago south-east of New Guinea. It was split from the Bismarck whistler by the IOC in 2015.

Taxonomy and systematics

It has been variably considered a subspecies of a widespread golden whistler (P. pectoralis) or treated as a separate species, but strong published evidence in favour of either treatment is limited, and further study is warranted to resolve the complex taxonomic situation.

Subspecies

Two subspecies are recognized:

• P. c. collaris - <small>Ramsay, 1878</small>: Found in the Louisiade Archipelago except Rossel Island
• P. c. rosseliana - <small>Hartert, 1898</small>: Originally described as a separate species. Found on Rossel Island (Louisiade Archipelago)
