The
Oriental Greenfinch is well-named, with a normal range in eastern Asian that
extends from Kamchatka Peninsula of Russia in the northeast, southward
through Japan, North and South Korea, eastern and southern China, and
Vietnam. They are also sometimes called the Gray-capped Greenfinch. As
with some other passerines in far eastern Asia, they have been found as rare
vagrants in the far western Aleutian Islands. Elsewhere in North
America, there are confirmed sightings of Oriental Greenfinches in
California and in British Columbia in Canada. However, the source of
the birds found in North America outside of the Aleutian Islands and Bering
Sea may be questionable, with some sources considering these birds to be
likely escapees from captivity rather than true wild vagrants. The
likelihood of these birds being escapees is probably low, however, as there
are extremely few records of Oriental Greenfinches being kept by either
hobbyists, or by zoos and aviaries.
Habitat: During the summer breeding season,
Oriental Greenfinches are most commonly found in coniferous to mixed
coniferous/deciduous forests. A much wider variety of habitats are used in
migration and during the winter months, as they may be found in forest edges
and woodlands, riparian areas, shrublands and second-growth forest, and in
suburban parks and gardens.
Diet: Feeds primarily on seeds and grains. They
will also feed on insects, spiders, and other small invertebrates,
particularly during the summer breeding season.
Behavior: Uses a variety of foraging techniques
depending upon the food item, and may feed either on the ground, in shrubs
or other low vegetation, or even high in a tree canopy.
Nesting: The nest is a cup of grasses and moss,
lined with fine grasses and softer vegetation, placed in a tree or sometimes
a bush. The female lays 2 to 5 eggs and she alone incubates them.
Song: The call of an Oriental Greenfinch is a
distinct, nasal "djeeeeee"
Migration: Most Oriental Greenfinches are
non-migratory. However, the sub-species that breeds in Kamchatka is
migratory. This migratory sub-species is the one that is almost
certainly the source of vagrant birds in North America.
Feeders: In their normal
range, Oriental Greenfinches will attend feeders for a variety of
offered seeds, suet, and nuts.
Similar Species:
Most similar to the European Greenfinch, a species that has not been found
in North America. The Eurasian Siskin has similar plumage on the wings
and tail, and is also a species that has been found on rare occasions as a
vagrant on the western Aleutian islands. Of North American birds,
Pine Siskins have similar patterns on the
wings and tail, but plumage on the body is quite different and they are
unlikely to be confused with Oriental Greenfinches.
Conservation Status: The Oriental Greenfinch is
found across a very broad geographic range, is common in parts of its range,
and the overall population is considered stable.
The IUCN lists the
Oriental Greenfinch as a species of "Least Concern".
