The
Asian Rosy-Finch is a finch species found in Asia. Its normal range
extends from Japan, Norrth and South Korea, and Kamchatka peninsula in the
east, westward through parts of eastern Russia, Mongolia, China, and
Kazakhstan. They are related to the
Gray-crowned Rosy-Finch,
Black Rosy-Finch, and
Brown-capped Rosy-Finch of North America. They are not known to
wander long distances and thus were not a species that could normally be
expected even as a vagrant in North America. However, iin late
December 2011, a lone Asian Rosy-Finch was sighted on Adak Island in the far
western Aleutians, and thus the species was added to the official American
Birding Association's checklist of birds that have been sighted in North
America.
Habitat: Found in open habitats that may vary
depending upon breeding location. They are often found in and around
sub-alpine to alpine meadows (as high as 18,000 feet) that are interspersed
with rocky slopes, barren rock, and cliffs. In some lower elevation
coastal areas they may be found on bare rocky beaches.
Diet: Feeds primarily on seeds, but they will also
take insects (particularly during the summer breeding season), and may
occasionally eat berries and fresh buds and shoots of plants.
Behavior: Most foraging is done on the ground.
They gather seeds while walking and hopping on the ground, and during the
summer months will do the same with insects and spiders.
Nesting: Breeding biology of Asian Rosy-Finches is
poorly understood, as the species is little studied, and few nests have been
observed.
Song: unknown
Migration: Some populations of Asian Rosy-Finch
are likely permanent residents, although those found at higher elevations
will move to lower elevations for the winter. Some more northerly
populations may make short migratory flights.
Conservation Status: Populations have declined
substantially in recent decades. However, they are still found over a
very wide geographic range, and are common to even abundant in parts of
their breeding range.
The IUCN considers
the Asian Rosy-Finch as species of "Least Concern".
