Order Passeriformes
Family Thamnophilidae

This species is found in Central and South America, from southern Mexico and Guatemala to Venezuela and western Colombia, through Ecuador, Peru and Bolivia and into central, eastern and south-eastern Brazil. The plain antvireo is also found in Paraguay and extreme northern Argentina, as well as in Trinidad and Tobago.

These birds are 11-12 cm long and weigh 12,5-15 g.

The plain antvireo is found in both rainforests and dry savannas, and to a lesser extent in swamp forests, at altitudes of 600-2.500 m.

They forage on the lower branches of the trees taking insects and other arthropods, namely bees, moths, ants, katydids and spiders.

Plain antvireos breed in February-July. The nest is a deep cup made of made of small twigs and plant fibres, placed in an horizontal fork in a sapling up to 2 m above the ground. The female lays 2 white eggs with purple-brown spots, which are incubated for about 15 days. The chicks fledge 9 days after hatching.

IUCN status – LC (Least Concern)
This species has a very large breeding range and a global population estimated at 500.000-5.000.000 individuals. This population is suspected to be in decline owing to ongoing habitat destruction, but it appears to tolerate some degree of habitat disturbance and human activity.
