The Patagonian Sierra-Finch is a small songbird that lives in far southwest South America. They are sparrow-like in appearance and behavior, but more closely related to tanagers. They have slate-grey or blue-grey hoods, wings, and tails. The body color may be russet or reddish with a yellow or green tinge.
Patagonian Sierra-Finches eat both plant and animal matter. Besides seeds, fruit, and insects, they may dine on nectar or sap. They will visit back yard feeding stations and have also been seen feeding from scraps of garbage.
