Chunky, sluggish bird of lowland and foothill tropical broadleaved forests. Male has brilliant crimson underparts, a black head, and a triangular pinkish nape. Female is brown-headed with a sharp and solid white line between head and red breast. Red-headed Trogon female has a thinner, incomplete white collar. Often perches quietly at middle levels, frequently in pairs. Song is an echoing series of rising hoots that levels off.
