The presence of a Jack Snipe on the local nature reserve last week, once
again highlighted the value of birdwatching a local patch. The finder, a
colleague from work, visits the site on a regular basis throughout the year.
Every now and then one of these visits turns up something unexpected or
unusual, just reward for the amount of effort put in to watching the same site
and its visiting birds on many occasions throughout the year.
Although the Jack Snipe is a smart little wader, it is rather secretive
in its habits and rarely strays far from damp, well-vegetated cover. If you are
fortunate enough to see one from a bird hide then you may well be treated to
its furtive, crake-like feeding behaviour. The bird will tend to pick at food
items on the surface, probing less often than its more familiar relative, and
sometimes bobbing its body up and down like some peculiar clockwork toy. Your
more typical view of a Jack Snipe is to see one launch itself from the piece of
vegetation next to which you have just placed your foot. Once in the air, the
Jack Snipe tends to stay rather low, flying in a straight line (Common Snipe
zig-zags and gains height rapidly) before quickly dropping back down into
suitable cover.
While the nature of its escape might suggest the Jack Snipe to be
somewhat weak when it comes to flight, it is actually a long distance migrant,
with some birds from the Siberian breeding population known to winter in
sub-Saharan Africa. Others, from the western end of the breeding range, pass through
Britain in the autumn, with some overwintering here. Arrivals here tend to
begin in mid-September, increasing through October then dropping before the
return movement in April.
The migratory nature of the species, coupled with its somewhat secretive
habits and choice of feeding habitats, mean that we have a very poor
understanding of this species. Of particular concern is the degree of
uncertainty surrounding estimates of its population size. If we do not know how
many Jack Snipe occur in Europe (or beyond) then how can we reliably determine
if their populations are in difficulty, perhaps declining with the loss of
favoured habitats to afforestation or land drainage.
While both Woodcock and
Common Snipe are familiar birds to me, often seen on my ramblings around the
Brecks, the Jack Snipe is a bird that I have seen only on a handful of
occasions. I might just make a few more visits to the reserve over the coming
week to see if I too can strike it lucky. Even if I don’t, there is always the
chance that I might stumble across something else equally fascinating.
