Puna Yellow-Finch
Sicalis lutea
A compact, high-altitude specialist of the Andes, the Puna Yellow-Finch is notable for its vibrant, uniform yellow plumage and its affinity for rocky, treeless landscapes. It is a characteristic member of the Thraupidae family adapted to the extreme conditions of the Altiplano.
What it sounds like
A sharp, thin 'tsip' or 'seet' contact call; the song is a rapid, buzzy series of high-pitched whistles and trills.

Field notes
- It is a strict high-elevation specialist, rarely occurring below 3,000 meters and reaching up to 5,000 meters above sea level.
- Unlike most other Sicalis species, the adult male lacks heavy dark streaking on its back, appearing almost entirely bright yellow with olive-washed wings.
- The species is known to nest in rock crevices and stone walls, an adaptation to the lack of arboreal nesting sites in its native habitat.
- It frequently forms nomadic flocks outside the breeding season, often mixing with Bright-rumped Yellow-Finches and various sierra-finches.
- Its bill is notably thicker and more robust than that of the closely related Citrine Yellow-Finch, facilitating the processing of hardy alpine seeds.
Habitat
Arid puna grasslands, rocky slopes, and edges of high-altitude wetlands (bofedales).
Range
High Andes from central Peru through western Bolivia to northern Chile and northwestern Argentina.
