Himalayan Thrush

The Himalayan, or Himalayan forest, thrush is a species described in 2016 and separated from the alpine thrush, with which it was formerly lumped. It was separated on the basis of phylogenetic studies suggesting the population diverged from the common ancestor at least 3 million years ago, with estimates varying from 3 to 6 million. The alpine thrush breeds above the tree line, whereas the Himalayan thrush breeds in forested habitats; it breeds from Sikkim and Darjeeling in India east into Tibet and further east into north-west Yunnan in China (Wikipedia, general species account).

The two differ in song: the Himalayan thrush has a more musical call, while the alpine thrush's is raspy and grating. The cached account gives no description, measurements or breeding information. SoIB 2023 rates it a Moderate conservation priority, a resident and altitudinal migrant forest bird with a Restricted range of about 8,220 km² and insufficient data on trends (Wikipedia, general species account; SoIB 2023).
