The mountain bulbul (Ixos mcclellandii) is a songbird species in the bulbul family, Pycnonotidae. It is often placed in Hypsipetes, but seems to be closer to the type species of the genus Ixos, the Sunda bulbul. It is found in Southeast Asia and is not considered a threatened species by the IUCN. It is named after British East India Company Surgeon John McClelland.
The mountain bulbul was originally described in the genus Hypsipetes in 1840 by Thomas Horsfield. Alternate names for the mountain bulbul include the green-winged bulbul, McClelland's bulbul, McClelland's rufous-bellied bulbul, mountain streaked bulbul, and rufous-bellied bulbul. The common name, 'mountain bulbul', is also used as an alternate name for the Cameroon greenbul.

Rare
Under 5% of wildlife watchers report a Mountain Bulbul sighting in Namdapha National Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 198th most-seen of the 298 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 April
In those months about 10% of wildlife watchers report a Mountain Bulbul in Namdapha National Park on a given day, against under 5% in February–March, May and October–December, the lowest months. Those are among Namdapha National Park's driest months, with about 160 mm of rain a month against 660 mm in July. June to September have too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Mountain Bulbul sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
4th of 5
Of the 5 parks where we can rate Mountain Bulbul sightings, Namdapha National Park ranks 4th at under 5%. The best odds are in Doi Inthanon National Park (Thailand, about 40%), Kaeng Krachan National Park (Thailand, about 10%) and Royal Manas National Park (Bhutan, about 10%).

GBIF citizen-science records
It is estimated from how often the Mountain Bulbul is recorded against all the birds logged in Namdapha National Park (35 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.
