Possible
About 30% of wildlife watchers report a Red-naped Trogon sighting in Way Kambas National Park on a given day, based on 104 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 205 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
May
In that month about 50% of wildlife watchers report a Red-naped Trogon in Way Kambas National Park on a given day, against about 10% in October, the lowest month. November to February have 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.
Yes
Of the 6 parks where we can rate Red-naped Trogon sightings, Way Kambas National Park has the highest daily chance: about 30%. Next come Danum Valley Conservation Area (Malaysia, about 20%) and Sepilok (Malaysia, about 10%).
Same genus: Harpactes
The closest relatives of the Red-naped Trogon that you can see in Way Kambas National Park (genus Harpactes, Asian Trogons) are Scarlet-rumped Trogon (about 30%) and Diard's Trogon (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red-naped Trogon is recorded against all the birds logged in Way Kambas National Park (104 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.
