Supertramp fantail

The supertramp fantail (Rhipidura semicollaris) is a species of bird in the family Rhipiduridae that is found on the Lesser Sunda Islands, Maluku Islands, Kai Islands and Aru Islands. It was formerly considered to be subspecies of the Arafura fantail (Rhipidura dryas). Its natural habitat is subtropical or tropical moist lowland forests.

Taxonomy
The supertramp fantail was formally described in 1843 by the German naturalist Salomon Müller based on specimens collected in Timor. He placed it with the other fantails in the genus Rhipidura and coined the binomial name Rhipidura semicollaris. The specific epithet combines the Latin semi- meaning "half" with collaris meaning "collared". The supertramp fantail and its subspecies were formerly treated as being conspecific with the Arafura fantail (Rhipidura dryas).
