The black-breasted thrush (Turdus dissimilis) is a species of bird in the family Turdidae. It is found from north-eastern India to northern Vietnam. 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 bird's breast. They tend to live in forests located at high altitude.
The black-breasted thrush belongs to the order Passeriformes and the family Turdidae. The species is a monotypic taxon – it has been hypothesized that it forms part of a larger superspecies, classified together with Tickell's thrush (T. unicolor) and the grey-backed thrush (T. hortulorum). It was previously thought to have conspecificity with the latter species of thrush. The black-breasted thrush was first described by Edward Blyth in 1847 and was found in the lower Bengal region.
The black-breasted thrush is 22 centimetres (8.7 in) to 23.5 centimetres (9.3 in) long in total, including its tail. Whereas the lower parts are the same colour for both sexes, the upper and middle parts are where they differ. For... Wikipedia →

Likely
About 50% of wildlife watchers report a Black-breasted Thrush sighting in Guiyang on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 60% of wildlife watchers report a Black-breasted Thrush in Guiyang on a given day, against about 30% in August and November, the lowest months. That is one of Guiyang's wettest months, with about 180 mm of rain against 25 mm in February. February has too few records to rate.
Between 1 and 4 am
Across all the parks we cover, that three-hour window holds the most Black-breasted Thrush sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Yes
Of the 3 cities where we can rate Black-breasted Thrush sightings, Guiyang has the highest daily chance: about 50%. Next come Kunming (China, about 10%) and Hanoi (Vietnam, under 5%).
GBIF citizen-science records
It is estimated from how often the Black-breasted Thrush is recorded against all the birds logged in Guiyang (33 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
