It is found in forest, scrub and cultivation across tropical southern Asia from the Himalayas, India and Bangladesh east to Indonesia. The white-spotted fantail (R. albogularis) until recently was considered a subspecies. DescriptionThe adult white-throated fantail is about 19 cm long. It has a dark fan-shaped tail, edged in white, and white supercilium and throat. There is otherwise much variation in plumage between races. Most resemble the Himalayan R. a. canescans which is mainly slate grey above and below, with a black eye mask, and a white throat and eyebrow.{{citation needed|date=April 2017}} Local names for the bird in India include Nasoni sorai (Assamese). BehaviourThe white-throated fantail lays three eggs in a small cup nest in a tree. It is insectivorous, and often fans its tail as it moves through the undergrowth. Birds use the same song year after year, with progressively small changes, with the result that the song sounds very different after 4–5 years. The male's call is a valuable tool in detection and identification of the bird, which can often be confused with the white-browed fantail, R. aureola, where their ranges overlap. R. aureola has light underparts and prominent spots in two rows on the wings. Its call is rather functional, and not as pleasant and aesthetic as that of R. albicollis.{{citation needed|date=April 2017}} GalleryReferences1. ^BirdLife International. 2016. Rhipidura albicollis.
