[edit] Distribution

South America: found from the Andes of Peru to Tierra del Fuego.

[edit] Taxonomy

This thread discusses a recent (2011) phylogenetic study of the genus.

[edit] Subspecies

There are three polytypic and one monotypic groups[1]

  • P. f. fruticeti
  • Andes of northern Peru to Bolivia (La Paz and Cochabamba)
  • P. f. peruvianus smaller than nominate, with heavier streaking on upperparts. In fresh plumage brighter and more reddish brown above
  • Andes of south-western Bolivia to southern Chile and southern Argentina
  • P. f. coracinus male nearly completely black during breeding season.
  • Andes of Bolivia (western Oruro and Potosí)

[edit] Habitat

Lives in open and partially open arid habitats. In the Andes it occupies shrub covered hillsides, including Polylepis forest edge and cultivated land. In the steppes of Patagonia it lives in flat steppe, often covered with Berberis microphylla. In Central Chile it occupies lower agricultural areas and open matorral cactus habitats. It is found in altitudes, in the Patagonian steppe and in Central Chile during the winter, of up to 4000 m.

[edit] Behaviour

[edit] Diet

Seeds and invertebrates, and small fruit when available. Winter studies in Central Chile shows 98% seeds and 2% invertebrates. Terrestrially foraging in pairs or small flocks. Nearly always in flocks outside of the breeding season.

[edit] Breeding

Breeds from September to March in most of it's range. Central Chile from October to January, a bit later in Patagonia. Fledglings have been recorded in December in La Paz, Bolivia. Records show that eggs hatch in April and May in Peru.

Seems to be partially colonial without strong territorial behaviour during the breeding season and displays all the time. Flies up to height of 4–10 m, and sings in a glided descent.with widely spread wings and tail. Wings are held slight lowered during descent.
Nests are slack and sloppy, made of grass and lined with spongy matter in thick low bushes. 2–3 eggs, light green dappled greeny brown.

[edit] Vocalisation

Song a loud, buzzing and rasping sound like some icterids, the buzz often pstarts with a short “chip” and ends with “pik-chzzzzzééééé chwiip” In central Chile, the song is higher and buzzier than in northern Chile, northwest Argentina, Peru and Bolivia. In Peru and northern Chile the song lacks the initial “chip”. Call is a raspy “shweaaa”, nasal sounding.
