The yellow-browed bulbul (Acritillas indica), or golden-browed bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in the forests of southern India and Sri Lanka. The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos.
The yellow-browed bulbul was originally described in the genus Trichophorus (a synonym for Criniger) in 1839 by T. C. Jerdon on the basis of specimens from the Wynaad region and given the original binomial (or protonym) of Trichophorus indicus. Formerly, the yellow-browed bulbul was classified in the genus Iole as two separate species but a study determined that this species is exceptional and it is now placed in the monotypic genus Acritillas. Some authorities have included the yellow-browed bulbul in the genus Hypsipetes but a 2018 molecular phylogenetic study indicated the nearest living relative... Wikipedia →

Rare
Under 5% of wildlife watchers report a Yellow-Browed Bulbul sighting in Udawalawe National Park on a given day, based on 14 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 139th most-seen of the 166 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and November
In those months about 10% of wildlife watchers report a Yellow-Browed Bulbul in Udawalawe National Park on a given day, against under 5% in February–October and December, the lowest months. Those are among Udawalawe National Park's wettest months, with about 220 mm of rain a month against 45 mm in June.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Yellow-Browed Bulbul sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 9
Of the 9 parks where we can rate Yellow-Browed Bulbul sightings, Udawalawe National Park ranks 7th at under 5%. The best odds are in Sinharaja Forest Reserve (Sri Lanka, about 70%), Periyar National Park (India, about 60%) and Mudumalai National Park (India, about 10%).
GBIF citizen-science records
It is estimated from how often the Yellow-Browed Bulbul is recorded against all the birds logged in Udawalawe National Park (14 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.
