Godwit Fact File
Smaller than a curlew, the black-tailed godwit is a large wading bird with a
very long straight bill and long legs. In spring, the head, neck and breast are
a striking chestnut-red colour. In flight, it shows a white wing-stripe and a
black and white tail. It has suffered a large breeding population decline in the
past and is now a rare breeder. It is a summer visitor to its breeding grounds,
wintering in Africa. Birds from northern Europe spend the winter on UK coasts.
Much of the lowland wet grassland where godwits like to nest has disappeared
from Britain and most breeding colonies are now on nature reserves where these
habitats are carefully managed. Throughout Europe, godwit breeding numbers are
declining because of drainage of wetlands.
Eggs: 3-4
Incubation: 22-24 days
Fledging: 20 days
Maximum lifespan: 15 years
Length: 40-44 cm
Wingspan: 70-82 cm
Weight: 290-350 g
UK breeding: 30-50 pairs
Up to two pairs of black-tailed godwits have nested near the estuary for several
years and the nestwatch scheme has helped protect these rare breeding birds from
thieves who may try to steal the eggs for their illegal collections.
Black-tailed godwits are fully protected by UK law and anyone convicted of
taking their eggs would face a fine of up to £5,000 for each incident or six
months in prison.
The breeding
Black-tailed Godwits of Newton Marsh - a race apart
The Black-tailed Godwit has a discontinuous breeding distribution
from Iceland to Siberia with three forms (distinct populations)
being recognised of which two breed in Europe; the nominate form limosa
and the form islandica. Islandica which, as
it's name suggests breeds principally in Iceland, is currently
increasing and, as it is Black-tailed Godwits of this form
thatoccur in some numbers on the Ribble Estuary and elsewhere in
the British Isles as non-breeding visitors, this population rise
has been reflected in higher counts here. Therefore, it might
seem likely that the breeding Black-tailed godwits at Newton
Marsh are islandica which have chosen to remain to breed
by the Ribble Estuary, indeed as many as 200 islandica
regularly visit Newton Marsh to feed late into the spring.
However, the nominate form limosa is the only form which
regularly breeds in the British Isles, primarily on RSPB reserves
in Cambridgeshire.
Since Black-tailed Godwits were discovered breeding on Newton
Marsh their form has remained unknown until this year when, after
good views, they have been confirmed as being of the
internationally declining form limosa. Limosa
breeds in the Low Countries through to Russia and is a true long
distance migrant wintering mainly in sub-Saharan Africa and
India.
But does it really matter which form of Black-tailed Godwit
breeds at Newton Marsh? Well it may prove to be crucial factor in
determining the future of breeding Black-tailed Godwits at the
site. It is most unlikely that islandica will ever breed
so far south and so recruitment of breeding birds from the
growing wintering population on the Ribble Estuary is therefore
not likely to occur. Black-tailed Godwits are long-lived birds so
the same adult birds are probably returning to nest at Newton
Marsh each year. If breeding success remains low in future years
and breeding godwits are ultimately lost from Newton Marsh it
seems unlikely that they would ever return.
Black-tailed godwits -
spot the difference
Telling limosa from islandica in the field is
not easy but to the trained eye a combination of features often
makes it possible.
