With luck
About 10% of wildlife watchers report a Red-headed Trogon sighting in Manas National Park on a given day, based on 98 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 192nd most-seen of the 377 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.
January
In that month about 20% of wildlife watchers report a Red-headed Trogon in Manas National Park on a given day, against under 5% in February and April–November, the lowest months. That is one of Manas National Park's driest months, with about 15 mm of rain against 1070 mm in June.
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.
6th of 11
Of the 11 parks where we can rate Red-headed Trogon sightings, Manas National Park ranks 6th at about 10%. The best odds are in Namdapha National Park (India, about 30%), Cuc Phuong National Park (Vietnam, about 30%) and Khao Yai National Park (Thailand, about 30%).
GBIF citizen-science records
It is estimated from how often the Red-headed Trogon is recorded against all the birds logged in Manas National Park (98 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.
