The plain antvireo is a small, understory antbird that forages methodically in dense foliage. Pairs often duet, giving simple, evenly spaced notes that carry through forest thickets. Unlike obligate ant-followers, it mostly gleans insects from leaves and twigs, only occasionally attending army-ant swarms. It has many subspecies with subtle regional plumage differences.
Temperament
shy and secretive
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen in pairs or small family groups maintaining territories in the understory. Often joins mixed-species flocks while foraging but stays low and inconspicuous. Nest is a small cup suspended in a fork of slender stems or vines, with both sexes participating in care.
Migratory Pattern
Resident
Song Description
Simple series of clear, evenly spaced notes or a soft, accelerating sequence; calls are sharp chips. Pairs may duet, with phrases exchanged between male and female from concealed perches.
