The black-browed fulvetta (Alcippe grotei) is a 15.5 to 16.5 cm long species of passerine bird in the family Leiothrichidae. It is found in subtropical or tropical moist montane evergreen forests, adjacent secondary growth and bamboo in Cambodia, Laos, Thailand, and Vietnam.
It is often considered conspecific with the mountain fulvetta, Alcippe peracensis, but the two forms differ in morphology and vocalisations, and are separated altitudinally. Black-browed fulvetta occurs primarily below 400 m, and mountain fulvetta above 900 m.
Both have a warm brown back and tail, whitish underparts, a grey face and a slate grey crown edged below with a black line. Black-browed has brown flanks and a weaker white eyering; it has been described as a bit like a cross between mountain and grey-cheeked fulvetta. The black-browed has a song yu-chi-chiwi-chuwoo, yu-uwit-ii-uwoo, whereas the mountain is yi-yuii-uwee-uwee.
Two subspecies are recognised: Family Timaliidae (Babblers) pp. 70 – 291 in; del Hoyo, J., Elliott... Wikipedia →

Possible
About 30% of wildlife watchers report a Black-browed Fulvetta sighting in Cuc Phuong National Park on a given day, based on 112 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 23rd most-seen of the 159 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
October
In that month about 50% of wildlife watchers report a Black-browed Fulvetta in Cuc Phuong National Park on a given day, against about 10% in April, the lowest month. July has too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Black-browed Fulvetta 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.
Only Cuc Phuong National Park, in our data
Cuc Phuong National Park is the only park on Wallace's Line with enough records to rate Black-browed Fulvetta sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-browed Fulvetta is recorded against all the birds logged in Cuc Phuong National Park (112 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.
