It is the 3rd most-seen of the 92 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.

In that month about 70% of wildlife watchers report a Red-eyed Bulbul in Kubah National Park on a given day, against about 30% in December, the lowest month. That is one of Kubah National Park's driest months, with about 200 mm of rain against 520 mm in January. January–February, September and November have too few records to rate.
Between 7 and 10 am

Of the 13 parks where we can rate Red-eyed Bulbul sightings, Kubah National Park ranks 3rd at about 50%. The best odds are in Khao Luang National Park (Thailand, about 70%) and Sepilok (Malaysia, about 50%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Red-eyed Bulbul is recorded against all the birds logged in Kubah National Park (41 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.
