Breeding / Nesting ... Diet / Feeding


The Mourning Sierra Finches (Phrygilus fruticeti) are large tanager finches found in the Andes of South America, where they are regionally quite common and widespread. These birds were named for the black, grey and white plumage of the males - colors that are generally associated with mourning.

They are close relatives of the similar Carbonated Sierra Finch (Phrygilus carbonarius) found in Argentina.

Distribution / Habitat

The range of the Mourning Sierra Finches stretches from Peru south through Bolivia, northern, central and eastern Chile east and south to western and southern Argentina. Vagrants have been reported in Brazil and the Falkland Islands. Some migrate south to spend the summer in Patagonia (southern tip of South America).

In the north, they are restricted to dry montane shrubland in the high Andes at elevations from 7,500 - 14,000 feet (~2,300 - 4,200 meters). Further south in their range, they are also found at lower altitudes down to sea level.

They are most common in open dry and rocky areas with scrub and shrubby vegetation and seem to avoid forests or open grasslands.

They are usually seen in pairs or small groups. They may also join mixed species feeding flocks or form small flocks outside the breeding season.
