Bougainville dwarf kingfisher
The Bougainville dwarf kingfisher, is a species of bird in the family Alcedinidae that is endemic to Bougainville Island. Its natural habitat is subtropical or tropical moist lowland forests.
This species was formerly considered as one of the 15 recognised subspecies of what was then known as the variable dwarf kingfisher. A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another. The variable dwarf kingfisher was therefore split and 12 of the subspecies, including the Bougainville dwarf kingfisher, were promoted to species status by some taxonomic authorities. Others have left it as a subspecies of the North Solomons dwarf kingfisher.
