The Collared Trogon (*Trogon collaris*) is a strikingly beautiful bird of Neotropical forests, renowned for its vivid, almost iridescent plumage. Males boast a deep emerald-green head, chest, and upperparts, contrasted by a bright red belly and a distinctive white band—the "collar"—across the chest, while females are equally elegant in soft brown and gray with a similar collar. A unique characteristic shared by all trogons is their heterodactyl toe arrangement, where the first and second toes face backward, an adaptation that helps them grip branches while perched motionlessly for long periods. Special features include a long, squared tail with white barring on the underside, and a stout, slightly serrated bill used to pluck fruit and catch large insects or even small lizards mid-flight. Their habit of sitting perfectly still in the forest understory, often with their back to an observer, makes them a captivating but challenging sight for birdwatchers.

Faits amusants

The Collared Trogon is a dedicated sitter, often remaining motionless for hours on a perch, relying on its cryptic plumage to vanish against the forest backdrop while it waits to snatch insects or fruit in mid-air with a swift, acrobatic flight. It has a quirky habit of nesting in abandoned termite mounds or rotting tree cavities, where both parents share incubation duties in a surprisingly tight squeeze. One of its most unique adaptations is heterodactyl feet, with toes arranged in a forward-backward-forward pattern (instead of the typical three-forward, one-back), which gives it an expert grip on branches but makes walking on the ground nearly impossible.

Habitats et répartition

The Collared Trogon inhabits humid tropical and subtropical forests, including lowland rainforests, montane cloud forests, and mature secondary growth. It is most commonly found in the understory and mid-story layers of these dense, evergreen forests, often near streams or ravines. Its geographical range extends from southeastern Mexico through Central America (Belize, Guatemala, Honduras, Nicaragua, Costa Rica, Panama) and into South America, where it occurs across the Amazon basin in Colombia, Ecuador, Peru, Bolivia, Venezuela, the Guianas, and northern Brazil, as well as on the island of Trinidad.

Comportements & Reproduction

The Collared Trogon is generally solitary or found in pairs, maintaining a loose monogamous social structure during the breeding season. Mating involves mutual courtship feeding, where the male offers fruit or insects to the female, and duetting calls to strengthen the pair bond. A unique reproductive strategy is their use of excavated cavities in decaying trees or termite nests, which both sexes help dig out, though the female typically lays two to three white or pale blue eggs. Incubation is shared, with the male taking the day shift and the female at night, and both parents feed the altricial chicks until fledging. Unlike many birds, trogons do not build a nest structure, relying solely on the cavity for protection.

Alimentation

The Collared Trogon is primarily a frugivore, with fruits—especially small, soft, lipid-rich berries and drupes from trees like mistletoe and palms—making up the vast majority of its diet. It is an adept aerial forager, often sallying out from a perch to pluck fruit mid-flight or hover briefly to snatch it, and it will also swallow small fruits whole, regurgitating the pits later. Interestingly, while fruit dominates, it is also a skilled insectivore, actively hunting large insects such as caterpillars, beetles, stick insects, and cicadas, which it captures in the same sallying manner; this protein source is especially crucial during the breeding season for feeding chicks. A distinctive feeding behavior is its habit of beating large or spiny prey against a branch to subdue and soften it before swallowing.

Couleurs

The Collared Trogon (Trogon collaris) displays striking sexual dichromatism: males have a metallic green head, upper breast, and back, a white band across the breast separating it from a vivid red belly, and blackish wings with fine white vermiculations; females replace the green with a warm brown head and back, with a more subdued buff breast band and paler red underparts. Both sexes share a unique white chest band, a long, square-tipped tail with black-and-white barring underneath, and a blue orbital ring. Their coloration provides disruptive camouflage in dappled forest light, breaking up their outline against foliage and shadows.
