White-winged fantail

The white-winged fantail (Rhipidura cockerelli) or Cockerell's fantail, is a species of bird in the family Rhipiduridae. It is found in the Solomon Islands apart from the island of Malaita in the southeast of the archipelago. The white-gorgeted fantail (Rhipidura coultasi) was formerly considered as a subspecies.

Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.

Taxonomy
The white-winged fantail was formally described in 1879 by the Australian ornithologist Edward Pierson Ramsay based on a specimen that had been collected by James F. Cockerell on Guadalcanal in the Solomon Islands. Ramsay coined the binomial name Sauloprocta cockerelli. The specific epithet was chosen to honour the collector. This species is now placed with the other fantails in the genus Rhipidura that was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield.

Six subspecies are recognised: The white-gorgeted fantail (Rhipidura coultasi) was formerly treated as a subspecies. It is endemic to the island of Malaita in the southeast Solomon Islands.
