The Eurasian Siskin is a very small and
very active member of the finch family, “Fringillidae”. It also falls into the
category of “winter finch”, as it is part of a group of finches that breed in
the extreme north and generally only visit southern temperate regions during
the winter months. All winter finches, including crossbills, siskins and others
also follow several year cycles of migration in which they are absent in
southern regions for several years and then numerous for one year. These
irregular migration patterns are directly related to climatic changes and
variable food supplies.
The range of the Eurasian Siskin is
separated in two sections through Eurasian One part is in North Europe with the
other in North Asia . It is absent from the
portion of Russia
that separates these two sections. Its summer breeding range includes the
extreme northeast of Heilongjiang Province up into Russia . In the winters that it
chooses to seek southern climes, it can be found throughout much of east China as far south as Shenzhen and Hong Kong .
Like other winter finches, the Eurasian
Siskin is a largely a seed eater which can survive without difficulty at
northern latitudes where coniferous forests offer seeds all year long.
This species is always seen feeding high in
the trees as it rarely ventures close to the ground. It is quite acrobatic in
its search for food in the trees, often hanging upside down in the manner of a
tit.
During winters that it ventures south to
temperate regions, it will feed from seeds of both coniferous and deciduous
trees. In summer, this bird will feed its chicks insects, as the proteins found
in animal matter will allow for faster development of their young.
During the winter males and female form
pairs that will mate in the coming spring. The birds construct a nest high in
the upper branches of coniferous tree, usually a pine. The female lays 2-6 eggs
and incubates them herself. The chicks are “nidiculous’, meaning that they
remain close to their nests long after hatching remaining dependant on their
parents for food.
