Description:
The Siskin is
one of our smallest finches (smaller than a Goldfinch). It
has a relatively long and narrow bill for a finch and also
has a distinctive forked tail. The plumage is predominantly
a yellow-green colour, with a striking yellow band on the
wing and yellow patches at the base of the tail. Adult males
have a black crown and a lot of black in the wing, which contrasts
with the yellow wing-band. Females are greener in colour than
the males, streaked above and without the black crown. Juveniles
resemble females but are buff-brown above and more heavily
streaked (both above and below).
Ecology & Behaviour:
The breeding
range of Siskins within Britain has expanded following the
spread of new conifer plantations. This, coupled by the exploitation
of peanuts provided in gardens, has resulted in a dramatic
increase in the number of Siskins visiting gardens during
the late winter months. Almost invariably it is after the
New Year that Siskins begin to be reported in increasing numbers
in gardens. In spring, there is a rapid movement of birds
away from gardens and back to the breeding areas. Birds continuing
to visit gardens during the breeding season will be local
breeders, with adults accompanied by young a feature of late
summer in these areas.
Movements into
gardens to feed quite possibly occur after the alder seed
crop has been exhausted. This is supported by the way in which
the peak Garden BirdWatch reporting rate for Siskin varies
from year to year, corresponding to the quality of the seed
crop.
