Editing Collared trogon (section)

==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/>
