Distribution
The grey
wagtail is found throughout Europe except for Scandinavia .
In the United Kingdom it is found most frequently in the summer in the hilly
regions of England, Wales and Scotland, next to fast-flowing streams, and in
winter at lower levels in farmyards, watercress beds and the like.
Appearance
The grey
wagtail is some 18-19 centimetres (7 inches) in length, being noticeable for
its long tail which is about an inch longer than that of the yellow wagtail.
Male grey wagtails are grey on the head and back but yellow on the rump, chest
and underparts, fading to white on the flanks. Their wings are dark grey and
they have a black throat. Female grey wagtails lack the black throat and have
less yellow in their plumage. In winter the males lose the black on their
throats and the yellow colouring on all grey wagtails is less pronounced. The
tail, on both males and females, is black with white edging and the legs are
flesh coloured.
Behaviour
Grey wagtails
are more often seen on the ground than in flight, running along stream edges
with tails wagging as they look for water beetles and insect larvae in the
shallow water. They will also perch on boulders and overhanging trees. In
winter they can be seen around farmyard and stable muckheaps, hunting for
insects or taking flies on the wing. They are usually seen singly or in family
groups, but roost gregariously in waterside trees.
The grey
wagtail has a high metallic call and a trilling warble. A clip of these can he
heard on the appropriate page of the RSPB (Royal Society for the Protection of Birds) website.
Breeding
Grey wagtails
nest close to water, sometimes in holes in old bridges or walls. Five or six
eggs are laid at any time between April and June, these being incubated by both
partners for up to 14 days. Both parents also feed the young birds, for 12 or
13 days in the nest and for a short time after they have fledged. A second
brood may be raised.
Conservation
Although grey
wagtails have gradually increased their UK range over time, and are sometimes
seen in urban as well as rural settings, their numbers can be badly affected by
harsh winters and recent years have seen a decline. They are therefore
classified on the red list of birds that are in danger of
extinction in the UK.
