The Black-headed Trogon (Trogon melanocephalus) is a species of bird in the family Trogonidae. It is found in Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, and Nicaragua. Its natural habitats are subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and heavily degraded former forest.
This Trogon measures 28 cm (11 in) and weighs about 89.4 g (3.15 oz). Males and females both have bright yellow underparts with a narrow band of white separating the yellow from a dark chest. Distinctive markings include a dark eye surrounded by a light blue eye ring and black tail feathers with broad white tips. Males have black heads and breasts with a blue-green sheen on the nape, back, and wings. Females are similar, but duller yellow below and slate grey above, with none of the blue-green sheen of the male. [Wikipedia]
