Thecollared trogon (Trogon collaris) is anear passerinebird in familyTrogonidae, the quetzals and trogons. It is found inMexico, throughoutCentral America, and in northernSouth America.[2]
TheInternational Ornithological Committee (IOC) and theClements taxonomy recognize these 10 subspecies of collared trogon. They treatedT. c. aurantiiventris ("orange-bellied trogon") as a separate species until the late 2010s.[2][3]
BirdLife International'sHandbook of the Birds of the World (HBW) recognizes eight subspecies, excludingT. c. aurantiiventris andT. c. underwoodi.[4]
Trogons have distinctive male and female plumages, with soft, often colorful, feathers. The collared trogon is about 25 to 29 cm (9.8 to 11.4 in) long and weigh about 41 to 64 g (1.4 to 2.3 oz). Both sexes have a black face and throat. The male's crown, nape, back, and rump are bright metallic green. The folded wing shows black and whitevermiculation. The breast is also metallic green with a white band separating it from the bright red belly and vent. The upperside of the tail is green with a black tip and the underside is barred black and white. The female is olive brown where the male is green, the closed wing is brown with black vermiculation, and the belly is a duller red than the male's. The underside of the tail is gray with a few black bars and white tips.[5]
The 10 subspecies of collared trogon are found thus:[2][5]
Clements placesT. c. exoptatus in Trinidad & Tobago; the IOC placesT. c. collaris there instead.
In South America the collared trogon inhabits humid lowlandevergreen forest, bothprimary and well-establishedsecondary. In Mexico and Central America it inhabits those forest types and in addition humidmontane, semideciduous, and pine-evergreen forests. It is found as high as 2,400 m (7,870 ft) in Mexico and 2,300 m (7,550 ft) in Costa Rica, but in the Andes it is mostly below 1,300 m (4,270 ft) in Ecuador and 1,200 m (3,940 ft) in Peru.[5]
The collared trogon usually perches between the higher understory and the lower part of the canopy. It is usually seen singly or in pairs, but small groups may gather outside the breeding season.[5]
The collared trogon eats small fruits (such as berries)[6] and invertebrates such as caterpillars, crickets, cicadas, beetles, and phasmids.[6] They often accompany the edges ofmixed-species foraging flocks but do not mix with the other members.[5]
The collared trogon's nesting season is highly variable across the species' wide distribution, beginning as early as November in French Guiana and as late as April in Venezuela. It nests in cavities in decaying wood or arboreal termite nests; the cavity is often so shallow that much of the bird is visible. The normal clutch size is two eggs. Both sexes incubate the eggs and care for the young.[5]
| Songs and calls |
The collared trogon's song varies geographically. The Mexican and Central American populations sing "a plaintive 2-3 notedkyow'-kyow or caow' caow, and a fasterkyow kyow-kyow". South American songs are described as "a series of mellow whistled notes, usually with a stuttered introductory note:whi'whi whew-whew-whew." Calls include "a prolongedcharr" and a "snortingchur-r-r-r".[5]
TheIUCN has assessed the collared trogon as being of Least Concern. It has a very large, though not quantified, population and a very large range.[1]
