SNIPE

Snipe
are medium sized wading birds, a bit smaller than a Lapwing (Peewit). They have
a very long bill, about a quarter of their total length, and feed in soft mud.
Seen close to, they are richly patterned in black, brown and rufous, with
cream stripes on the head and back. From
a distance, they look dark golden brown.

Snipe
are secretive, and crepuscular, and are much more likely to be heard than seen.
They have a characteristic “drumming” display flight, usually at dusk but
occasionally during the day, and a “chipping” call, emitted from deep cover
in the marsh. Drumming occurs mainly in the very short twilight period around
dawn and dusk, and might be heard at any time between March and the last week in
July. Wintering and passage birds usually do not drum or chip, although passage
birds are known to drum occasionally in April.
Males
arrive on the breeding territory about ten days before the females.
Initially their “drumming” display flight occurs over quite a wide
area, although there is no deep encroachment into areas covered by other males.
As incubation becomes more advanced, the area of the display flight is much more
restricted, and is closer to the nest.
First eggs are usually laid at the end of April or beginning of May,
usually in a tussock of grass or rush. Incubation takes around 20 days. Chicks
leave the nest shortly after they hatch, and feed themselves.
The parents divide the brood between them, and separate.
The male ceases territorial defence, including drumming flights, as soon
as this parental responsibility starts.
If
the first clutch is lost, the male will continue to defend the territory, and a
new clutch will be laid. Several
repeat clutches may be laid, until either one hatches successfully, or the
breeding area becomes too dry for the birds to feed. Young birds are potentially
independent of their parents as soon as they fledge, about 20 days after
hatching.
Feeding
areas need to be close to the nest – long foraging flights to food increase
the risk of the adult being predated, and the location of the nest being
observed on the bird’s return. Their
long bill is used to probe mud or soft soil for prey – mainly earthworms, but
also insects and snails. The margin
between wet and dry areas is their most important feeding area – worms cannot
survive in ground that is permanently flooded.
Snipe
suffer a very high rate of nest loss, mainly through predation and trampling by
livestock. They will lay repeat clutches until nesting females cannot access
food close to the nest. Once the ground dries out, and becomes hard, Snipe are
unable to feed there, even if there are still substantial amounts of prey below
the surface.
Snipe have disappeared as a breeding bird in much of lowland
A
national survey carried out by the British Trust for Ornithology in 2002 found a
94% decline in the
A Survey was carried out in 2004 to establish the population, distribution and breeding requirements of Snipe in the south-west Shropshire Hills. For the Executive Summary from the Report click here.
On
the Long Mynd, an estimated 7 – 8 pairs were found.
This is only around one-third of the population found in 1994-98. The
range has also contracted considerably – Snipe were only found on and around
Wild Moor, but they were found all across the moorland plateau 10 years ago.
On
The Stiperstones NNR, none were found, although Snipe are known to have bred
there in 1995-96, when the population was estimated at six pairs.
On
Rhos Fiddle, a Shropshire Wildlife Trust Nature Reserve in the Clun Uplands, an
estimated 3 - 4 pairs were found (including a possible pair at an
adjacent site on Bicton Hill).
In
addition, a large number of other apparently suitable sites throughout the
south-west Shropshire Hills (total area approximately 580 square kilometres)
were assessed. The 25 sites judged to have the greatest potential to hold
breeding Snipe were then surveyed. Only three of these sites were found to hold breeding
Snipe:
Each
of these three sites apparently only held one pair, so the total estimated
population of all 25 sites is only three breeding pairs.
The
total population of the Survey Area is therefore estimated at 13 – 15 breeding
pairs.
Unless
there are substantial populations in areas currently not known to conservation
bodies and birdwatchers, the County population is now estimated at only 20-25
pairs.
In
common with other ground-nesting wading birds (Lapwing and Curlew), numbers have
declined considerably in recent years as a result of land drainage, and
concentration of the reduced population in smaller areas which make them more
vulnerable to the increasing number of predators. This increase is attributed to
the large amount of carrion available as supplementary food for these predators,
a by-product of intensive sheep farming and pheasant rearing in the last 10-15
years.
Because
of the high rate of nest loss, Snipe need an extended breeding season. This
maximises the number of repeat clutches that can be laid, thereby increasing the
chance of a successful nest. Extending
the date on which a female can commence a new clutch from 10 June to 10 July has
been estimated to double the number of chicks per female. As first-year birds
breed later than mature birds, increasing the available habitat later in the
season also gives them a chance to breed.
Thus
maintenance of high water tables throughout the breeding season, but avoiding
extensive surface flooding, is likely to produce the best conditions.
A network of ditches and varied surface topography, providing abundant
damp, penetrable areas even when the water table is low, will also enhance the
habitat for Snipe.
Therefore, any site which holds breeding Snipe, or which has the
potential to attract them, should be managed to achieve extensive areas of short
vegetation that are wet (not damp), from the beginning of April until the end of
July. The four regular territories on the one kilometre length of the stream
that flows into Wildmoor Pool suggests a distance between the centre of each
territory in optimum habitat of 250m. The average territory includes around two
hectares of acid / wet flush.
In
addition, management proposals should also aim to:-
As
farmers are now being encouraged to manage their land to increase the Snipe
population through Defra’s new Environmental Stewardship Scheme, hopefully
more of this habitat will be safeguarded and created.
