Trogonidae Trogons

These generalist foragers of tropical forests often reveal their presence only by their deep whistled or chuckled calls. Once spotted, trogons can be distinguished by their hunched shoulders and long tails, and their underparts of bright yellow, red, or orange and upperparts of iridescent dark green or blue or matte cinnamon make a feast for the eyes. Sexual dimorphism in trogons grows most extreme in the quetzals, in which even the males, with their spectacularly long tail coverts, take an active role in incubating and feeding chicks in their tree-hole nest. Males sometimes aggregate loosely for days at a time early in the breeding season, but why they do so remains unclear.
