Thick-billed Siskin

Spinus crassirostris

The Thick-billed Siskin is a small finch found in the high-altitude Andean forests of South America. It is characterized by its stout, conical bill and distinctive yellow and black plumage. These birds are highly social and often form large flocks, foraging for seeds and small insects in the forest canopy. Their breeding season is typically during the austral summer, and they build cup-shaped nests in trees or shrubs. The Thick-billed Siskin is an important seed disperser in its ecosystem, contributing to the maintenance of forest diversity.
