Citreoline Trogon Trogon citreolus Scientific name definitions

Endemic to western Mexico, the Citreoline Trogon is fairly common in arid or semi-arid woodland habitats, mangroves and plantations up to 1,000m. 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. Near Ocozocuatla, where it may overlap with the similar Black-headed Trogon, 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. This species sometimes forms vocal leks attended by several females and builds its nest in termitaries.

27 cm. Male nominate race with bill pale blue-grey, eye yellow; head and breast dull greyish-black, creamy white breast­band, yellow rest of underside; wings greyish-black; mantle and back green, rump and uppertail-coverts deep blue; uppertail bluish-green, tipped black; undertail largely whitish with black border. Differs from similar T. melanocephalus in greyer, less black, head and breast, yellow eye and no visible orbital ring, less blue tinge to green of back, less black on undertail. Female has rather dark grey head, breast and back, upper mandible partially blackish. Juvenile with dark eye, slightly more black on undertail. Race <em>sumichrasti</em> larger, with broader white tips to outer rectrices.
