The hawfinch (Coccothraustes coccothraustes) is the largest finch in the United Kingdom, but its numbers have been in decline in recent years and it is on the “red list” of endangered bird species in the UK. It is more plentiful in continental Europe and across Asia as far as
Its habitats
comprise thin deciduous woodland, large parks, orchards and gardens, at all
altitudes from lowland to mountains.
Appearance
The most distinctive
feature of the hawfinch is its huge (for a bird of its size) parrot-shaped
beak, which is used for cracking open cherry stones and other large seeds. Its
head and neck are suitably large and well-muscled for performing this
operation.
The hawfinch
measures around 16-17 centimetres (6.5 inches) in length. It has long wings and
a short, squarish tail. The head is a rich brown colour, with a grey neckband
and a black bib. The underparts are mainly a pinkish brown and the upperparts a
darker brown. The wings are glossy black with white patches, and the tail has a
white tip. Female hawfinches are not as richly coloured as the males.
Behaviour
The flight is
fast, undulating and high. Hawfinches often perch in treetops, and come to
ground infrequently during the breeding season. They are therefore more easily
spotted at other times of the year, especially when the trees are leafless and
hawfinches are more likely to feed on the ground. When on the ground they stand
quite upright, hopping or walking.
Adult
hawfinches will take insects on the wing, but the main part of its diet
comprises seeds and kernels as mentioned above.
The song of
the hawfinch is not easily heard, being soft and unobtrusive, and consisting of
clicks and whistles.
Breeding
The nest is
built in late April or early May, anything from two to ten metres above the
ground in broadleaved or fruit trees. A thick layer of twigs is surmounted by a
nest of roots, plant stalks and grass that is lined with hairs and soft, fine
vegetation. Four to six eggs are incubated by the hen hawfinch alone, who is
brought food by the cock. The nestlings hatch after about 14 days and are fed
insects and soft seeds until they leave the nest after a further two weeks.
Only one brood is raised.
