Description:
Although similar
in size and shape, the Brambling can be instantly distinguished
from the Chaffinch by its white rump, orange-buff colouration,
flecked flanks and lack of white on the outer tail feathers.
Male Bramblings are more strongly marked than both females
and immatures. Confusion with Chaffinch may occur if the bird
is not seen well, when the wing pattern can be suggestive
of Chaffinch. Both the flight call, and the sound of a roosting
flock are distinctive.
Ecology & Behaviour:
Bramblings are
migrants, wintering south of the breeding range and in varying
numbers depending upon the availability of beech mast. It
is only really in poor mast years, with bad winter weather
that any number can be seen feeding in British gardens. Most
of those reaching Britain come from Fennoscandia, arriving
via the Continent to avoid crossing the large expanse of the
North Sea. While Chaffinches will exploit beech mast if it
occurs locally, Bramblings very clearly move to find beech
mast.
Garden BirdWatch links
Garden BirdWatch results show
that the occurrence of Bramblings in gardens can vary dramatically
from one year to the next.
A 'Focus On' article on the Brambling
appeared in issue 4 of the Bird
Table magazine. Garden BirdWatch participants can download
a copy of this article from the participant only pages.
