The
Eurasian Siskin, also known as the European Siskin, Common Siskin, or simply
"Siskin" in much of its native range, is a small finch with a broad range
across Europe and Asia. The largest popoulation covers much of Europe,
eastward into western Russia and Asia. Another population is found in
far eastern Asia, including Japan. In North America, they are but rare
vagrants. Sightings accepted as those of true wild, vagrant birds by
the American Birding Association has occurred on multiple occasions in the
Aleutian Islands, on Atta and Unalaska. Other sightings with
unequivocal photo documentation have occurred in other parts of North
America, including Wisconsin, Maine, near Winnepeg in Canada, and
Newfoundland. Many birding groups consider the sightings outside of
the Aleutians to be escapees from captivity. Eurasian Siskins are
sometimes kept as cage birds in Europe, but that's simply not the case in
North America. The species also has been known to wander widely, and
there's nothing about the observations (leg banding, abnormal behavior for a
wild bird, etc.) outside of the Aleutians that would indicate a domestic
origin.
Habitat: Found in a variety of conifer and mixed
conifer/evergreen forests during breeding, but often found in and around
areas of spruce trees. They will use a much wider variety of habitats in
migration and in winter, including riparian areas, deciduous forests and
woodlands, thickets and shrublands, and urban and suburban parks and
gardens.
Diet: Feeds on seeds, often with a preference for
spruce and pine seeds. They will also feed on the catkins and seeds from
birches and alders, and other seeds. During the breeding season,
insects and other small invertebrates are also taken.
Behavior: Quite active birds, they will use a
variety of foraging techniques depending upon food source and location.
They are often seen hanging upside down as they hold onto a pine or spruce
cone, extracting and consuming seeds with their fine, pointed bill.
They will also feed on the ground, or clamber through shrubs or tree
canopies in search of food. They are very social birds outside of the
breeding season, often found in flocks that not only include other Eurasian
Siskins, but also sometimes other small passerines.
Nesting: The nest is built by the female, and is a
cup of fine grasses, mosses, lichen, downy feathers, and other material that
may be available. She lays 2 to 5 eggs, and she alone incubates the eggs,
although the male will typically deliver food to the female during the
incubation period. The eggs hatch after about 12 days. The young
fledge from the nest about 2 weeks after hatching, but may stay in the
vicinity and continue to be cared for by the parents for another week or
two.
Song: A weak whistled CHURR-reee call is often
given while in flight. The song is a longer serious of relatively quiet
musical phrases, varying in pitch throughout and ending with a harsher rasp.
Migration: Across its broad geographic range, some
Eurasian Siskins are semi-permanent residents. However, many
populations, particularly those in the northern parts of their summer
breeding range, are migratory and move southward for the winter. While not a
true, seasonal migratory behavior, Eurasian Siskins are also nomads, often
wandering in search of areas with strong spruce and pine seed crops.
Similar Species:
Similar in size and structure to North America's
Pine Siskins, and shares some of the similar wing and tail patterns.
Overall though, Eurasian Siskins are much more brightly colored, with
substantially more yellow tones on the body.
Conservation Status: Eurasian Siskins are found
across a very broad geographic area, they are common in parts of their rane,
and despite declines in overall numbers in recent decades, the overall
population is still very high.
The IUCN considers
the Eurasian Siskin as species of "Least Concern".
