The dark-backed sibia (Heterophasia melanoleuca) is a bird species in the family Leiothrichidae. In former times it was included the black-headed sibia, H. desgodinsi. Together with most other sibias, it is sometimes separated in the genus Malacias. It is found in China, Myanmar and Thailand. Its natural habitat is subtropical or tropical moist montane forests.

Likely
About 60% of wildlife watchers report a Black-backed Sibia sighting in Doi Inthanon National Park on a given day, based on 2,508 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the most-seen of the 367 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
May
In that month about 80% of wildlife watchers report a Black-backed Sibia in Doi Inthanon National Park on a given day, against about 50% in November to January, the lowest months. That is one of Doi Inthanon National Park's wettest months, with about 290 mm of rain against 20 mm in February.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Black-backed Sibia sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Doi Inthanon National Park, in our data
Doi Inthanon National Park is the only park on Wallace's Line with enough records to rate Black-backed Sibia sightings: about 60% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-backed Sibia is recorded against all the birds logged in Doi Inthanon National Park (2,508 verified sightings from 2019 to 2026), 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.
