Typical Environment
Found in inter-Andean valleys and adjacent uplands of central Bolivia, favoring a mosaic of dry scrub, open woodland, and farmlands. It often uses hedgerows, pastures, and riparian thickets near villages and ranches. The species tolerates moderate habitat alteration and can be seen along fence lines and field margins. It prefers semi-open habitats rather than dense forest.
Altitude Range
1200–3000 m

A member of the Icteridae, the Bolivian blackbird is the sole species in the genus Oreopsar. It is restricted to Bolivia’s inter-Andean valleys, where it frequents open woodlands, scrub, and agricultural edges. Its limited range makes it of conservation interest, and it often associates with human-modified landscapes.
Temperament
social and active
Flight Pattern
strong flier with direct, purposeful wingbeats
Social Behavior
Typically seen in pairs or small flocks, especially outside the breeding season. It forages on the ground and low vegetation, sometimes following livestock to catch disturbed insects. Nests are likely cup-shaped and placed in shrubs or small trees, with both parents attending young.
Migratory Pattern
Resident
Song Description
Vocalizations include harsh chatters and sharp notes interspersed with simple whistles. Calls carry well across open country and are given from exposed perches such as fence posts or treetops.
Plumage
Mostly uniform glossy black plumage with a sleek, smooth appearance.
Diet
An opportunistic omnivore that takes insects, larvae, and other invertebrates, along with small fruits and seeds. It often gleans from the ground, probes leaf litter, and picks prey from low branches. Around livestock, it seizes insects flushed by grazing animals.
Preferred Environment
Edges of fields, scrubby slopes, and riparian thickets where cover alternates with open foraging patches. Frequently uses human-altered habitats such as pastures, orchards, and village margins.
