In the Vietnamese adult description, the male’s head and breast are dark red, while the female’s are olive-brown. A study in Thailand found it nesting in cavities in rotting wood.
Adult males have a dark red head and upper breast; these areas are olive-brown in females. Both sexes have a pale red lower breast, rusty-brown back and white undertail edged in black.
From 2010 to 2016, researchers repeatedly surveyed villages and valleys in Upper Siang, Arunachal Pradesh, India. Their regional checklist records a Red-headed Trogon at Bomdo in January, in the 900–1,000 m elevation class. The survey area around the village includes forest, fields, and fallow land.
The checklist recorded 252 bird species in the region, including 66 reported there for the first time. The authors emphasize that mixed-use landscapes outside protected areas support bird diversity. They highlight the value of fields, fallows, and forest patches together, and call for more surveys in remote parts of the region.
An extinction-risk assessment has not been added yet.
The Red-headed Trogon was recorded at Bomdo in January. The authors describe forests, fields, and fallows as a mosaic that supports the wider bird community. Continuing surveys outside protected areas and accounting for varied land uses can guide regional planning to maintain bird diversity.
