Description:
The Bullfinch
is a medium-sized to large finch, round in shape with a large,
robust bill. Both adult males and females have a black cap
that extends forward around the bill, together with a grey
back, black wings (with a grey-white wing bar), black tail
and white rump. The underparts of the adult male are rose-red,
while those of the female (and juveniles) are pinkish-grey.
Juveniles have a brown head, lacking the black cap.
The call note
is a low, piping ‘deu-deu’ (sometimes ‘deu’),
while the song is highly variable, though usually quiet in
nature and audible only over short distances.
Ecology & Behaviour:
Bullfinches appear
to have a well-developed pair bond, often maintained throughout
the year. Within Britain, the species breeds mainly in deciduous
woodland, but it will also use large gardens, thickets and
churchyards. Bullfinches are shy birds, rarely seen in the
open and seemingly visiting only those gardens that can be
accessed via suitably thick cover, hence a Garden BirdWatch
reporting rate typically well under 10%.
The nest is made
between 4 and 7 feet off the ground in cover and is made from
fine twigs, moss and lichens, and lined with a thick layer
of fine roots. It is during the spring that Bullfinches can
damage fruit trees by feeding on developing buds, with far
more being destroyed than are eaten. It is because of this
that the Bullfinch has been regarded as a pest in some areas
and controlled under licence.
Garden BirdWatch links
Garden BirdWatch results show
two peaks in reporting rate for Bullfinches, one in the winter
and one in late summer.
A 'Focus On' article on the Bullfinch
appeared in issue 18 of the Bird
Table magazine. Garden BirdWatch participants can download
a copy of this article from the participant only pages.
