The '''collared trogon''' ('''''Trogon collaris''''') is a [[near passerine]] [[bird]] in family [[Trogonidae]], the quetzals and trogons. It is found in [[Mexico]], throughout [[Central America]], and in northern [[South America]].<ref name=IOC11.2>{{cite web |url=https://www.worldbirdnames.org/ |title=IOC World Bird List |version=v. 11.2) |last1=Gill |first1= F. |last2=Donsker|first2=D.|last3=Rasmussen |first3=P. |date=July 2021 |access-date=July 14, 2021 }}</ref>

==Taxonomy and systematics==

The [[International Ornithological Committee]] (IOC) and the [[Clements taxonomy]] recognize these 10 subspecies of collared trogon. They treated ''T. c. aurantiiventris'' ("orange-bellied trogon") as a separate species until the late 2010s.<ref name=IOC11.2/><ref name=Clements>{{cite web|author=Clements, J. F.|author2= T. S.

==Description==

Trogons have distinctive male and female plumages, with soft, often colorful, feathers. The collared trogon is about {{cvt|25|to|29|cm|in}} long and weigh about {{cvt|41|to|64|g|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 white [[vermiculation]]. 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.<ref name="COTR-BOW">{{Cite journal |last=Inman |first=Seth |date=2020 |title=Collared Trogon (''Trogon collaris'')|version= 1.0 |url=https://birdsoftheworld.org/bow/species/coltro1/cur/introduction |journal=Birds of the World |language=en |doi=10.2173/bow.coltro1.01 |issn=2771-3105|url-access=subscription }}</ref>

==Distribution and habitat==

The 10 subspecies of collared trogon are found thus:<ref name=IOC11.2/><ref name=COTR-BOW/>

*''T. c. puella'', central Mexico to western [[Panama]]
*''T. c. underwoodi'', northwestern [[Costa Rica]]
*''T. c. aurantiiventris'', central Costa Rica to western Panama
*''T. c. extimus'',  eastern [[Darién Province]] in northeastern Panama
*''T. c. heothinus'', Panama's [[Serranía del Darién]]
*''T. c. virginalis'', western [[Colombia]] through western [[Ecuador]] into northwestern [[Peru]]
*''T. c. subtropicalis'', central Colombia, especially the Magdalena and Cauca valleys
*''T. c. exoptatus'', northern [[Venezuela]] (and [[Trinidad & Tobago]]?)
*''T. c. collaris'', east of the Andes from Colombia south to northern [[Bolivia]] and east through [[the Guianas]] and much of west central [[Brazil]] (and Trinidad & Tobago?)
*''T. c. castaneus'', southeastern Colombia south to eastern [[Peru]] and northern Bolivia and into northwestern Brazil; also eastern Brazil

Clements places ''T. c. exoptatus'' in Trinidad & Tobago; the IOC places ''T. c. collaris'' there instead.

In South America the collared trogon inhabits humid lowland [[evergreen forest]], both [[primary forest|primary]] and well-established [[secondary forest|secondary]]. In Mexico and Central America it inhabits those forest types and in addition humid [[montane forest|montane]], semideciduous, and pine-evergreen forests. It is found as high as {{cvt|2400|m|ft|-1}} in Mexico and {{cvt|2300|m|ft|-1}} in Costa Rica, but in the Andes it is mostly below {{cvt|1300|m|ft|-1}} in Ecuador and {{cvt|1200|m|ft|-1}} in Peru.<ref name=COTR-BOW/>

==Behavior==
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.<ref name=COTR-BOW/>

===Feeding===

The collared trogon eats small fruits (such as berries)<ref name="sta.uwi.edu">{{cite web|author=Shaquille Duncan|title=''Trogon collaris'' (Collared Trogon)|website=The Online Guide to the Animals of Trinidad and Tobago|publisher=[[University of the West Indies|UWI]] |url=https://sta.uwi.edu/fst/lifesciences/sites/default/files/lifesciences/documents/ogatt/Trogon_collaris%20-%20Collared%20Trogon.pdf}}</ref> and invertebrates such as caterpillars, crickets, cicadas, beetles, and phasmids.<ref name="sta.uwi.edu"/> They often accompany the edges of [[mixed-species foraging flock]]s but do not mix with the other members.<ref name=COTR-BOW/>

===Breeding===

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.<ref name=COTR-BOW/>

===Vocalization===

The collared trogon's song varies geographically. The Mexican and Central American populations sing "a plaintive 2-3 noted ''kyow'-kyow or caow' caow'', and a faster ''kyow 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 prolonged ''charr''" and a "snorting ''chur-r-r-r''".<ref name=COTR-BOW/>

==Status==

The [[IUCN]] has assessed the collared trogon as being of Least Concern. It has a very large, though not quantified, population and a very large range.<ref name="iucn" />
