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.

Ashy Antwren

The Ashy Antwren is a small Bolivian endemic antbird found in humid montane forests on the eastern Andean slopes. Weighing about 8.8g with a wingspan near 10.4cm, it is uniformly grey in coloration. It forages in the forest understory, often joining mixed-species flocks to glean insects from foliage.
