The recent weather has caused the river to overtop its banks and the
depth of water now present on the meadow has greatly changed the dynamics of
the site. Areas of exposed mud have been submerged and the geese that roost
here are now spread over a much larger expanse of water. The higher ground
remains dry, however, and the rabbits feed nervously on the short turf, ever
alert to danger and to the stoats that hunt here.
The flooding has made movement around the site less easy and our
nocturnal visits in search of snipe and woodcock more difficult. It is not so
much the depth of the water, which is readily tackled in wellingtons, but that
it has pushed these wintering waders into the tussocky swards where they are
difficult to spot. Snipe are jumpy birds at the best of times and the squelchy
of our approach, coupled with the agitated sounds coming from the roosting
geese, prompts many to flush before we get close enough to pick them out in our
torchlight.
These snipe are feeding rather than roosting, the latter a behaviour
usually restricted to the daylight hours. There are two peaks in feeding
activity. The first of these occurs during the early part of the night, the
second just before dawn. With their long and probing bills, snipe are able to
feed on a wide range of invertebrates, taking many beetle and fly larvae during
the course of their nocturnal foraging. Snipe can increase their body weight by
as much as 25% during the winter. This additional weight is added as a layer of
fat that insulates the bird and provides a food reserve should the weather
worsen and favoured feeding sites freeze over.
If the weather does deteriorate then the snipe will move south or
southwest in search of more favourable conditions. Some will remain, however,
seeking out the margins of streams and rivers, where the ground has yet to
freeze. Vast numbers of snipe winter here, often overlooked, with many arriving
from elsewhere within Europe. Wintering numbers mask conservation concerns
about a declining breeding population and more research work is needed identify
opportunities for improving the conservation status of these smart little
birds.
