|Ash-breasted Sierra-finch Geospizopsis plebejus
(aka Phrygilus plebejus)
Chilean name: Plebeyo
The Ash-breasted Sierra-finch is distributed in the Andes of Ecuador, Peru, western Bolivia, northern Chile and western Argentina south to Mendoza. There is a disjunct population on the Serra de Córdoba, Argentina. See the distribution map at Birdlife International.
|It is found mainly on rocky slopes in grassy areas of the
altiplano at between 3,000 and 4,000 metres.
It is the smallest sierra-finch and is common and conspicuous being found in large flocks in the non-breeding season. Presumably the fact that it is so common gave rise to both its specific and its Chilean name.
|The male, seen here in photos 1 and 2, is grey-brown above
with dusky streaks and pale grey below becoming whiter towards the belly. It has a pale supercilium and an whitish eye-ring broken by a dark line
through the eye. It has a peaked crown which can be seen in photo 1 and the bill is small and dark.
Although Fjeldså & Krabbe say that sexes are alike, most authorities mention that the female is lightly streaked on the throat and breast as can be seen on the birds in photos 3 and 4.
