Trogon personatus is a forest-dwelling bird found in the Andean regions of Venezuela, Colombia, Ecuador, Peru, and Bolivia, occupying humid montane and cloud forests at elevations typically ranging from 3,300 to 8,200 feet. It favors the interior and edges of dense forests and is often found perched quietly in the midstory or canopy. The species does not inhabit urban areas and remains within its native range across the Andean belt. It is considered fairly common in suitable habitats and does not appear on endangered species lists. Trogon personatus has several geographically separated populations that differ slightly in plumage coloration and vocalizations, and these are sometimes treated as subspecies.

Adults measure about 10 to 11 inches in length and are sexually dimorphic. Males are marked by a blackish-blue head and chest, iridescent green upperparts, and a vivid red belly separated by a narrow white band across the chest. Their tail is long with alternating white and black horizontal bars on the underside. Females have duller grayish tones on the head and chest and lack the distinct color separation seen in males. The species uses a slow, gliding flight pattern and often sits motionless for extended periods. It nests in tree cavities, often reusing abandoned woodpecker holes or natural crevices, and typically lays two to three eggs. Its diet includes small insects and fruits plucked in flight or while hovering near branches. Photographed in the Chocó region of Ecuador.
