Oreopsar bolivianus
The Bolivian Blackbird, *Oreopsar bolivianus*, is a striking member of the Icteridae family, an iconic group often associated with the Americas. This medium-sized passerine measures approximately 21-25 cm (8.3-9.8 inches) in length and weighs between 50-70 grams (1.8-2.5 ounces). Its plumage is predominantly glossy black, particularly noticeable on the male, with a slight iridescent sheen in good light. A key field mark for identification is its bright yellow iris, which contrasts sharply wit...
Found exclusively in arid to semi-arid inter-Andean valleys, typically at elevations between 2,000 and 3,500 meters (6,500-11,500 feet). It prefers areas with rocky outcrops, scattered shrubs, cacti, and agricultural fields.
Primarily insectivorous, feeding on beetles, grasshoppers, and other invertebrates, supplemented with seeds and some fruit, especially during non-breeding seasons. Forages mainly by gleaning on the ground.

Their foraging strategy involves walking and hopping, gleaning insects and seeds from the soil and low vegetation. They exhibit territorial behavior during the breeding season, w...
