With luck
About 10% of wildlife watchers report a Red-naped Trogon sighting in Tanjung Puting National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 58th most-seen of the 66 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
August to October
In those months about 10% of wildlife watchers report a Red-naped Trogon in Tanjung Puting National Park on a given day, against under 5% in May–July and November–March, the lowest months. April has too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-naped Trogon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 parks where we can rate Red-naped Trogon sightings, Tanjung Puting National Park ranks 5th at about 10%. The best odds are in Way Kambas National Park (Indonesia, about 30%), Danum Valley Conservation Area (Malaysia, about 20%) and Sepilok (Malaysia, about 10%).
GBIF citizen-science records
It is estimated from how often the Red-naped Trogon is recorded against all the birds logged in Tanjung Puting National Park (5 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.
