About These Birds
Bicolored Antvireo
The Bicolored Antvireo is a near-threatened small antbird restricted to foothill and lower montane forests of northwestern Ecuador and the southwest slope of Colombia. Males are grey and white and females are brown with buffy streaking. It forages in pairs in the forest midstory for insects gleaned from leaves and branches.
Black-headed Antbird
The Black-headed Antbird is a compact antbird; males have a bold black head contrasting with gray-blue underparts and brown upperparts, while females are brown with a rufous head. It inhabits dense, humid forests and river-edge vegetation in Amazonia, particularly in Brazil, Colombia, and Peru. It often accompanies army ant swarms, feeding on the small invertebrates they flush from the leaf litter.
