Biak paradise kingfisher

The Biak paradise kingfisher, Tanysiptera riedelii, is a tree kingfisher found only on Biak, an Indonesian island in a small group in Cenderawasih Bay off the northern coast of Papua. Adults measure about 36 centimetres including a long tail. They have a glossy turquoise-blue crown, nape and back, a white rump and belly, black underwings and a stout red bill. The two central tail feathers are greatly elongated, with bare shafts that flare into racket-shaped tips. Its habitat is forest, and it seems able to use secondary growth where tall trees remain. The bird is thought to descend from a few founding birds of the mainland common paradise kingfisher that became isolated on the island, and some authorities treat it as a subspecies of that bird. Its diet and behaviour have been little studied. The IUCN assesses it as near threatened, with logging a risk to its forest and the population likely to be declining.
