 Their back is brownish, the tail is partially white (best visible from below), and males of most species have red underparts.They feed on arthropods, small lizards and fruit.Two species, cinnamon-rumped and scarlet-rumped trogons, were previously classified in a separate genus, "Duvaucelius", and a 2010 study found that these two were closely related and formed a separate clade from all of the other "Harpactes" trogons (except orange-breasted trogon, which forms a third group), but recommended that all three groups should be treated as congeneric.
