The orange-spotted bulbul (Pycnonotus bimaculatus) is a species of songbird in the bulbul family of passerine birds. It is endemic to Java, Bali and Sumatra. It favors forest edges and open meadows in montane forests. The orange-spotted bulbul was originally described in the genus Turdus by Thomas Horsfield in 1821. Until 2016, the Aceh bulbul (Pycnonotus snouckaerti) was considered as a subspecies of the orange-spotted bulbul until split by the IOC. Most other authorities have not yet recognized this split.
It is a dark-colored and active bulbul with a rounded tail. It is a noisy bird, giving out a variety of harsh and loud calls and songs. It is a frugivore. It breeds throughout the year. Nesting occurs year-round, peaking in May. Nests are robust and cup-shaped. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Orange-spotted Bulbul is recorded against all the birds logged in Kerinci Seblat 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.
