Black-breasted Thrush

The Black-breasted Thrush(Turdus dissimilis) is a species ofbird in the familyTurdidae.It is found

inSouth Asia,Southeast Asia andChina.Although both male and female birds have the same colour

on their lower parts, the upper section of males is mostly black in colour, while females are mostly

grey-brown. Thus, the bird's common name refers to the colour of the male birds' breasts. They tend

to live in forests located at high altitude.

Taxonomy

The Black-breasted Thrush belongs to the orderPasseriformes and the familyTurdidae.The species

is amonotypic taxonit has been hypothesized that it forms part of a largersuperspecies,classified

together withTickell's Thrush (T. unicolor) and theGrey-backed Thrush (T. hortulorum). It was

previously thought to haveconspecificity with the latter species of thrush. The Black-breasted

Thrush was described byEdward Blyth in 1847 and was found in the lowerBengal region.

Description

The Black-breasted Thrush is 22 centimetres (8.7 in) to 23.5 centimetres (9.3 in) long in total,

including its tail. While the lower parts are the same colour for both genders, the upper and middle

parts are where they differ. For males, the section spanning from their head to theback of their

neck and breast area is black, while the remaining areas at the top areslate gray.On the other hand,

females aregray-brown from their eyes to their tail, while the section from their throat to their

breast is a "diffused" shade ofbuff.

Habitat

The bird is found inBangladesh,China,India,Laos,Myanmar,Thailand andVietnam.Their preferred

habitat aretropical and subtropicalmontane forests that are moist. Other suitable habitats that are

less important includetropical and subtropical dry forestsfor native populations that are resident

as well as tropical/subtropical moistshrubland andmangroves located above the level ofhigh

tide.In southwestern China, the bird can also be found inhilly areas.

They are typically found at relatively high elevations of between 1,220 metres (4,000 ft) to 2,500metres (8,200 ft) high. However, they tend to descend to loweraltitudes during the winter at around

200 metres (660 ft).

The Black-breasted Thrush has been placed on theLeast Concern category of theIUCN Red List,even

though its population has been decreasing throughout the last ten years. This is because the

reduction in the estimated population is not swift enough to meritVulnerable status under the IUCN

criterion for population trend, which is a decline of more than 30% in ten years or three

generations The population decline has been attributed to continuing "destruction and

degradation" of the bird's natural habitat. The size of its distribution range is over 752,000 square

kilometres (290,000 sq mi).
