Possible
About 20% of wildlife watchers report a White-rumped Triller sighting in Tangkoko Nature Reserve on a given day, based on 164 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April and August
In those months about 30% of wildlife watchers report a White-rumped Triller in Tangkoko Nature Reserve on a given day, against about 10% in May and September–December, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most White-rumped Triller sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate White-rumped Triller sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-rumped Triller is recorded against all the birds logged in Tangkoko Nature Reserve (164 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.
