Vireo Alcaudón Ventrirrufo Pteruthius rufiventer

Large-headed songbird with confusingly dissimilar male and female plumages. Male has an orange back, white throat, orangish belly, and a black head and wings. Female is green-winged and gray-headed, with a darker crown and triangular patch behind the ear. She shares the male’s warm-colored belly, but hers is more salmon-pink than orange-yellow. The species inhabits mature foothill forests, where it may often be seen with mixed-species foraging flocks.
