Despite the name, this species is a tanager (family Thraupidae) rather than a true finch. It is a characteristic bird of the windswept Patagonian region, often seen at forest edges and shrubby steppe. Males show a gray hood contrasting with yellowish underparts, while females are duller and more brownish. It frequently forages on the ground and may gather in small flocks outside the breeding season.
Temperament
social and active
Flight Pattern
short rapid wingbeats with undulating flight
Social Behavior
Breeds in pairs that defend small territories, placing a cup nest low in shrubs or dense vegetation. Outside the breeding season it forms small flocks and may associate loosely with other seedeaters. Displays simple ground and low-shrub foraging, with brief chases during courtship.
Migratory Pattern
Resident
Song Description
A bright, finch-like warble delivered from a low perch or shrub top. Calls include sharp chips and thin tseet notes used for contact within small groups.
