With luck
About 10% of wildlife watchers report a Red-naped Trogon sighting in Sepilok on a given day, based on 379 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 82nd most-seen of the 242 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.
February–April and October–December
In those months about 20% of wildlife watchers report a Red-naped Trogon in Sepilok on a given day, against about 10% in January and May–September, the lowest months.
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.
3rd of 6
Of the 6 parks where we can rate Red-naped Trogon sightings, Sepilok ranks 3rd at about 10%. The best odds are in Way Kambas National Park (Indonesia, about 30%) and Danum Valley Conservation Area (Malaysia, about 20%).
GBIF citizen-science records
It is estimated from how often the Red-naped Trogon is recorded against all the birds logged in Sepilok (379 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.
