Sicalis uropygialis
The Bright-rumped Yellow Finch, *Sicalis uropygialis*, is a striking and hardy passerine found exclusively in the high-altitude Andean regions of South America. Measuring approximately 13-14 cm (5.1-5.5 inches) in length, males are predominantly a vibrant yellow, characterized by a brilliantly bright yellow rump that gives the species its common name. Their backs are typically olive-yellow with dusky streaks, while some subspecies may display a greyish crown or nape, providing key identificat...
Found in the high-altitude Andean puna and altiplano regions, typically at elevations ranging from 3,000 to 5,000 meters (10,000 to 16,000 feet), favoring open grasslands, rocky slopes, and disturbed areas near human habitation.
Primarily consumes seeds from high-altitude grasses and herbaceous plants, supplemented with small insects, particularly during the breeding season, foraging by gleaning from the ground.
The Bright-rumped Yellow Finch is a diurnal species, spending its day actively foraging. It primarily gleans seeds and insects from the ground, often seen hopping methodically across sparse vegetation and bare earth. During the non-breeding season, these finches are highly gregarious, forming sma...
The Bright-rumped Yellow Finch is endemic to the central Andean highlands of South America, with its primary distribution spanning southern Peru, western Bolivia, northern Chile, and northwestern Argentina. Specifically, the subspecies *S. u. sharpei* is found in central Peru, while *S. u. chryso...
