Possible
About 30% of wildlife watchers report a Red-headed Trogon sighting in Khao Yai National Park on a given day, based on 734 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 278 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
March
In that month about 40% of wildlife watchers report a Red-headed Trogon in Khao Yai National Park on a given day, against about 10% in September, the lowest month. That is one of Khao Yai National Park's driest months, with about 85 mm of rain against 330 mm in September.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Red-headed Trogon 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.
Among the best
Of the 11 parks where we can rate Red-headed Trogon sightings, Khao Yai National Park ranks 3rd at about 30%, level with the leaders once rounded. The best odds are in Namdapha National Park (India, about 30%) and Cuc Phuong National Park (Vietnam, about 30%).
GBIF citizen-science records
It is estimated from how often the Red-headed Trogon is recorded against all the birds logged in Khao Yai National Park (734 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.
