Hooded Siskin Spinus magellanicus

Strikingly beautiful siskin found in woodland and grassland with scattered trees and usually highly gregarious; also sometimes associates with mixed-species flocks. Males have a black hood, wings, and tail, and are olive-yellow above and bright yellow below with large yellow wing patches. Females are duller and lack the black hood. The song is a long series of fast and squeaky notes; sometimes many males sing together.
