The rufous-backed antvireo is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil.
Region
Atlantic Forest of eastern Brazil
Typical Environment
Occurs in humid evergreen and semi-deciduous forests, using the understory to midstory of both primary and well-structured secondary growth. It favors shaded interiors and densely vegetated edges, where it moves methodically through foliage. Birds often accompany mixed flocks along narrow forest trails and ravines. It tolerates some disturbance but declines where forest is heavily fragmented.
Altitude Range
Sea level to 1200 m
Climate Zone
Tropical
Ease of Keeping
Beginner friendly: 1/5
A shy understory antbird of Brazil’s Atlantic Forest, it is more often detected by its thin, high whistles than seen. It frequently joins mixed-species flocks, gleaning small arthropods from foliage and twigs. Habitat loss and fragmentation in the Atlantic Forest likely affect its numbers, so local protection of forest patches is important.
Temperament
shy and skulking
Flight Pattern
short rapid wingbeats
Social Behavior
Typically seen singly or in pairs, often accompanying mixed-species flocks in the understory. Likely monogamous, maintaining small territories within suitable forest. Nests are presumed cup-shaped and placed low to mid-level in dense vegetation.
Migratory Pattern
Resident
Song Description
Song is a series of thin, high-pitched whistles, often slightly descending and delivered at intervals from concealed perches. Calls include soft chips and brief trills used to keep contact within pairs or with mixed flocks.
