Phrygilus atriceps
The Black-hooded Sierra Finch (Phrygilus atriceps) is a striking member of the Thraupidae family, known for its vibrant plumage and high-altitude Andean habitat. Males are instantly recognizable by their glossy black head, face, and throat, contrasting sharply with bright yellow underparts and a gray back. Measuring approximately 14 cm (5.5 inches) in length and weighing between 18-20 grams, this species is a robust high-elevation specialist. Females, while sharing the same general pattern, e...
This species primarily inhabits high-altitude Andean regions, favoring puna grasslands, rocky slopes, scree fields, and alpine tundra. It is typically found at elevations ranging from 3,000 to over 5,000 meters above sea level.
Their diet consists mainly of small seeds collected from the ground, supplemented by small insects and other invertebrates, especially during the breeding season.
Black-hooded Sierra Finches are diurnal, spending their days actively foraging. They are predominantly ground gleaners, meticulously searching for seeds and small invertebrates among rocks and sparse vegetation. During the breeding season, pairs establish and defend small territories, but outside...
The Black-hooded Sierra Finch has a widespread but restricted range across the high Andes of South America, primarily spanning Peru, Bolivia, Chile, and Argentina. Its core breeding range extends from central Peru southward through the Bolivian Altiplano, into the northern and central Chilean And...
Least Concern
- The Black-hooded Sierra Finch is one of the highest-dwelling passerines in the Andes, regularly found above 4,000 meters (13,000 feet). - Its bright yellow underparts are thought to provide a form of thermal regulation, absorbing solar radiation in its cold, high-altitude environment. - Unlike ...
