The mountain fulvetta (Alcippe peracensis) is a 14 to 15.5 cm long species of bird in the family Leiothrichidae. It is found in Cambodia, Laos, Malaysia, Thailand, and Vietnam in subtropical or tropical moist montane forests.
The black-browed fulvetta, Alcippe grotei, is sometimes considered to be conspecific with mountain fulvetta, 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 bordered below with a black line, but black-browed has brown flanks and a weaker white eyering. Mountain has a yi-yuii-uwee-uwee song, whereas black-browed's is yu-chi-chiwi-chuwoo, yu-uwit-ii-uwoo.

Rare
Under 5% of wildlife watchers report a Mountain Fulvetta sighting in Taman Negara National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 274th most-seen of the 293 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mountain Fulvetta in Taman Negara National Park on a given day, so our monthly data shows no clear season.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Mountain Fulvetta sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Taman Negara National Park, in our data
Taman Negara National Park is the only park on Wallace's Line with enough records to rate Mountain Fulvetta sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Mountain Fulvetta is recorded against all the birds logged in Taman Negara National Park (6 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.
