The Black-tailed Trogon (*Trogon melanurus*) is a strikingly beautiful bird of Neotropical forests, renowned for its vivid plumage and distinctive upright perching posture. Males boast a brilliant crimson belly and chest, set against a metallic green head and upperparts, while females are more subtly adorned with a gray breast and brown back, both sexes sharing a long, squared-off black tail with white undertail coverts. A unique characteristic is its heterodactyl foot arrangement—with toes two and three pointing forward—a feature shared only with trogons, which aids in grasping fruits and insects while perched motionless for long periods. Special features include a soft, resonant call often described as a series of low *cow-cow-cow* notes, and its habit of nesting in tree cavities or abandoned termite nests, where it lays chalky-white eggs. This elusive bird, found from Panama through the Amazon basin, is a master of stillness, making its vivid colors all the more striking against the dark understory.

Fun Facts

Unlike many birds that actively chase prey, the Black-tailed Trogon is a dedicated sit-and-wait predator, remaining motionless for long periods before launching a swift, direct flight to snatch insects or even small lizards from leaves or branches. It has a unique adaptation in its feet: the inner toe (toe 2) is actually reversed and points backward, a zygodactyl arrangement that gives it an incredibly strong grip for clinging to tree trunks and perching in awkward positions. A quirky behavior is its habit of excavating its own nest cavities in termite mounds or rotting wood, using its weak bill to peck out a chamber rather than relying on abandoned holes. Despite its vibrant red belly and green back, the bird’s plumage is surprisingly cryptic in the dappled forest understory, and it is more often heard than seen, producing a distinctive, slow, froglike “kwa-kwa-kwa” call that can be confused with a distant mammal.

Habitats & Distribution

The Black-tailed Trogon inhabits humid lowland and foothill forests, including tropical rainforests, secondary growth, and forest edges, often near watercourses. It is typically found from the canopy to the understory, favoring dense, shady areas with tall trees. Its geographical range extends from eastern Panama through Colombia, Venezuela, the Guianas, and across the Amazon basin in Brazil, Ecuador, Peru, and northern Bolivia. It also occurs on the island of Trinidad. The species is generally resident and does not migrate.

Behaviours & Reproduction

Black-tailed Trogons are generally solitary or found in pairs, maintaining a loose social structure centered on their breeding territory. During courtship, the male performs a display involving tail-fanning and bowing while offering food to the female, a key part of pair bonding. They are cavity nesters, typically excavating a nest in a decaying tree or termite mound, where the female lays 2–3 white eggs. Both parents share incubation duties for about 17–19 days, and the chicks fledge after roughly 15–17 days. A notable reproductive strategy is their reliance on pre-existing cavities or soft wood, as they lack strong bills for excavating hard substrates, making them vulnerable to nest site competition. Pairs often reuse the same nest site in successive seasons if available, showing site fidelity.

Diet

The Black-tailed Trogon is primarily a frugivore, with fruit making up the vast majority of its diet, but it is also an opportunistic insectivore. It feeds heavily on small, soft fruits, especially those from palm trees and other tropical forest plants, which it plucks while hovering briefly or perching. Interestingly, it often swallows fruit whole, later regurgitating the large seeds, making it a key seed disperser in its rainforest habitat. To supplement its diet, it actively hunts large insects like caterpillars, beetles, and walking sticks, as well as occasionally catching small lizards or frogs. A notable hunting strategy involves it sallying from a perch to snatch prey from foliage or the air, then returning to its perch to beat the catch against a branch before consuming it.

Colors

The male Black-tailed Trogon has a bright red belly, a metallic green head and upper breast, a blue bill, and a black tail with white undertail coverts; the female replaces the red with a brown belly and the green with a gray-brown back and head. Its unique coloration provides camouflage in dappled forest light, while the white undersides of the tail feathers flash during flight to confuse predators.
