The black-browed bushtit (Aegithalos iouschistos), also known as the black-browed tit or rufous-fronted bushtit, is a species of bird in the family Aegithalidae. It is found in mid-southern China and sporadically in Myanmar. Its natural habitats are boreal forests and temperate forests.
The black-browed bushtit was formally described in 1845 by the English zoologist Edward Blyth based on a specimen collected in Bengal. He coined the binomial name Parus iouschistos. The specific epithet combines the Ancient Greek ιοεις/ioeis meaning "dark" with Late Latin schistus meaning "slate". The black-browed bushtit is now one of eight species placed in the genus Aegithalos that was introduced in 1804 by the French naturalist Johann Hermann.
Four subspecies are recognised: Aegithalos iouschistos iouschistos (Blyth, E, 1845), the rufous-fronted bushtit – Himalayas (Nepal to northern India and southeastern Tibet) Aegithalos iouschistos bonvaloti (Oustalet, J-FÉ, 1892) – southern China (southeastern Tibet to Sichuan and Yunnan) and northeastern...

Possible
About 20% of wildlife watchers report a Black-browed Tit sighting in Langtang National Park on a given day, based on 65 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 62nd most-seen of the 225 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January and February
In those months about 40% of wildlife watchers report a Black-browed Tit in Langtang National Park on a given day, against about 10% in May–August and October–December, the lowest months. Those are among Langtang National Park's driest months, with about 50 mm of rain a month against 390 mm in July.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-browed Tit sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Langtang National Park, in our data
Langtang National Park is the only park on Wallace's Line with enough records to rate Black-browed Tit sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-browed Tit is recorded against all the birds logged in Langtang National Park (65 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.
