The Bolivian spinetail is a Vulnerable species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is endemic to Bolivia.
Region
Central Andes (Bolivia)
Typical Environment
Endemic to dry intermontane valleys of central Bolivia, where it favors arid to semi-arid scrub and thickets, often on steep slopes and along ravines. It uses dense, tangled vegetation with scattered shrubs, cacti, and small trees, and may occur along riparian thickets. The species typically forages from near the ground to mid-levels, weaving through vines and thorny brush. Fragmented habitat patches and ongoing conversion to agriculture restrict its distribution.
Altitude Range
1200–2500 m
Climate Zone
Subtropical
Ease of Keeping
Beginner friendly: 1/5
This secretive furnariid sticks to dense, thorny scrub where it creeps through tangles with its long rufous tail cocked upward. Habitat loss in Bolivia’s intermontane valleys has driven declines, leading to its Vulnerable status. It is usually detected by its dry, accelerating trill rather than by sight.
Temperament
skulking and active
Flight Pattern
short rapid wingbeats between bushes
Social Behavior
Usually encountered singly or in pairs, sometimes with dependent young. It occasionally associates with mixed-species flocks in scrubby edges. Nests are typically bulky, enclosed structures of sticks or fibers placed in dense vegetation, with both adults participating in care.
Migratory Pattern
Resident
Song Description
A dry, accelerating series of trills or chatters that can end abruptly, often delivered from within cover. Calls include sharp chips and rattles used for pair contact. Vocalizations are key for detection in dense scrub.
