The citreoline trogon (Trogon citreolus) is a species of bird in the family Trogonidae. It is endemic to western Mexico, with an estimated distribution size of 539,000 km2[2] Due to this very large range, the IUCN consider it a species of Least Concern and that the current population trend is stable.

Its natural habitats are arid or semi-arid woodland habitats, mangroves and plantations.[3] This species build nests in cavities in arboreal termitaria[4] (termite nests built in trees). It is thought that this nesting technique provides a critical role in creating necessary cavities for many organisms in tropical dry forests.[4]


Adult males have a uniform gray head and upper breast, and a metallic green mantle, fading to a violet-blue rump. The uppertail is blue-green with a black tip, and the wings are dark, with outer webs of the primaries white. The dark gray upper breast is separated from the bright yellow belly and undertail coverts by a broad but vaguely defined white band. Females are entirely dark gray above and tend to have a paler gray breast and paler yellow belly. Both sexes have dark bills and yellow eyes and predominantly white undertails.[3] Near Ocozocoautla de Espinosa, the Citreoline can overlap with the Black-headed trogon, in this area the Citreoline is paler overall with more white in the undertail (extending all the way to the undertail coverts in the outer webs) and lacks the dark eye and white eyering. [3]
