Beskrivelse: This is the <b>Himalayan Forest Thrush</b> (<i>Zoothera salimalii</i>) a species of bird described in 2016 and separated out from the <b>Plain-backed thrush</b> <i>Zoothera mollissima</i> with which they were formerly lumped.
The species is separated on the basis of phylogenetic studies that suggest that the population diverged from the common ancestor at least 3 million years ago (estimates vary from 3-6 mya).
The Alpine Thrush (<i>Zoothera mollissima</i> in the restricted sense) breeds above the tree line whereas the Himalayan Forest Thrush breeds in forested habitats. The species breeds from Sikkim and Darjeeling in India and extends into northwest Yunnan in China. The species differs in its song from that of the Alpine Thrush. The Himalayan Forest Thrush has a more musical call while that of the Alpine Thrush is raspy and grating.
The species name is given in honour of Indian ornithologist Sálim Ali.
The tree-dwelling species has shorter legs, tail and wings but a longer bill than its Alpine counterpart, and uses the shorter legs and tails to help it manoeuvre around in the forest.
