Description:
With its striking,
richly coloured plumage the Fieldfare is an impressive and
large member of the thrush family. The head is grey, as is
the rump which contrasts with the black tail and the rich
chestnut-red back and wings, the latter with much black in
the longer flight feathers. The chest and flanks are heavily
speckled with dark spots. The most often heard call note is
a harsh, aggressive sounding ‘chack-chack’.
Ecology & Behaviour:
As a winter visitor,
Fieldfares begin to arrive in October, continuing through
until the end of November. These arrivals are later in years
with good berry crops in Scandinavia. In bad years, as many
as a million Fieldfares may have no alternative but to head
over the sea to the British Isles in the hope of finding winter
sustenance.
These winter
flocks prefer open countryside, bordered by well-developed
hedgerows and woodland, only coming into gardens in the harshest
winter weather when the ground is frozen and soil invertebrates
are not available – many people think of Fieldfares
as fruit-eaters but in fact this is not the case, they much
prefer grubs and worms, switching to windfall apples and berries
when these invertebrates are unavailable.
Fieldfares often
breed in loose colonies and are very vigorous in their defence
against predators. There are even reports of birds ramming
Magpies and Jays in flight! Some observers are sure that there
are actually ‘guard’ Fieldfares which will escort
potential predators away from the colony. However the most
characteristic defence is well-aimed defecation directed at
the intruder.
Garden BirdWatch links
Garden BirdWatch results show
that the number of gardens reporting Fieldfares during the
winter months can vary quite a bit from one year to the next.
A 'Focus On' article on the Fieldfare
appeared in issue 12 of the Bird
Table magazine. Garden BirdWatch participants can download
a copy of this article from the participant only pages.
