Possible
About 20% of wildlife watchers report a White-chested Babbler sighting in Bako National Park on a given day, based on 31 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 28th most-seen of the 70 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
May
In that month about 40% of wildlife watchers report a White-chested Babbler in Bako National Park on a given day, against about 10% in January, March, July and October, the lowest months. November and December have too few records to rate.
Between midnight and 3 am
Across all the parks we cover, that three-hour window holds the most White-chested Babbler 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.
3rd of 9
Of the 9 parks where we can rate White-chested Babbler sightings, Bako National Park ranks 3rd at about 20%. The best odds are in Tanjung Puting National Park (Indonesia, about 40%) and Kinabatangan Wildlife Sanctuary (Malaysia, about 40%).
Same order: Passeriformes
The closest relatives of the White-chested Babbler that you can see in Bako National Park (order Passeriformes, Perching Birds) are Asian Glossy Starling (about 70%), Common Iora (about 70%) and Oriental Magpie-Robin (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-chested Babbler is recorded against all the birds logged in Bako National Park (31 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.
