Hmm, neglecting my blog readership in favour of my Facebook friends has found these pages embarrassingly out of date. Please keep coming back to check for catch ups including an account of my first trip helping out with the Delaware Shorebird Project as well as the trials and tribulations of endeavouring to hold down a full time job while ringing with three CES's this summer - yes, it can be done!
It had been a balmy October evening when three cannon nets
were set on Snettisham beach and after arriving under the cover of darkness on
a cooler Saturday morning the assembled team waited patiently albeit with eager
anticipation for the waders to arrive. Crackling radio commentary between base
camp laying in the marram grass and the hide team viewing the catching area
from the sea wall giving the only clue to progress. In, out, twinkle please,
switch in net two, hearts beat faster and bang! Feet were instantly carrying us
down to where the edge of net and water met and after guiding the birds safely
above the rising tide the rest of our morning began.
Keeping cages on the right allow birds time to settle down after the catch

Over 500 birds were caught of four species. The larger part
of the catch was Knot and Sanderling with two Grey Plovers and eight Dunlin
also processed – rings fitted to new birds, ring numbers recorded for those
that had already been ringed and a sample were measured and weighed to give an
indication of their health. Quite a few of the birds were actively moulting suggesting
that they are likely to use the Wash over the winter. It was nice to see a
number of new team members gaining their first close up encounters with some
wader species.

Unbelievably the October weather was warm enough to work on the beach in shorts barefoot, talk about an Indian summer! Incredulously other folk were trussed up in coats and hats - bizarre.
Beautiful sunset over the Wash.
On Sunday morning the team split up with smaller groups visiting
a number of sites to look for birds that have been colour ringed. Noting down
the combinations of the different colours or reading the codes on small plastic
leg flags means that data about movements of individuals can be recorded
without the need to re-capture the bird. It was a glorious autumnal morning and
over the weekend ninety colour ring combinations had been noted and flags read.
Little Stint - 2 were seen amongst the thousands of other waders
roosting in Snettisham Pits.
The black smudge to the left is 15,000 Oystercatchers!
One Sanderling was ringed in Iceland in 2011 and has spent
the last two winters in Spain, 3 Knot were seen that had been ringed in Norway
with another from Iceland but the real highlight was a total of 48 Curlew which
is more than the group would usually expect to re-trap in an entire year. This
really demonstrates the enormous value of colour ringing as a valuable tool that
can be employed to increase the amount of really useful encounter data that can
be acquired just using a pair of binoculars or a telescope, helping us to
increase our understanding of wader ecology and how these fascinating and
beautiful birds use the Wash; an understanding that will ultimately assist with
the conservation of the birds and their habitat.
I'm off to Canada at the end of the week so
this maybe my last Comma for the year.
