The Trimley Round up. Number 12. November
19th 2012

Yesterday
the estuary at Trimley marshes shined like a diamond in the wonderful autumn
sunshine. The last few weeks have certainly
been like gems, as we have experienced a ‘purple’ patch on the reserve.
During
the last month there has been a good visible ‘migration’ as we have seen birds
on the move. In October and November
along the bridleway there have been hundreds of Blackbirds arriving and feeding
on the fantastic berries on offer to them. The last few weeks have resulted in over 150 Blackbirds being ringed and
processed. An exercise which contributes significantly to our understanding of
‘migration’, as well as how birds are coping in an ever changing world and in
so many cases, in a decline of habitats.
Other species to visit the reserve these last few weeks have been Redwing, Fieldfare and Song Thrush. On November 6th we ringed a lovely Fieldfare and
over the last few weeks have also ringed a good number of Song Thrushes.
November 6th we also noted a very late group of 7 Swallows departing our shores.
The
smallest species of bird in Britain is the Goldcrest,
Just weighing a few grams and the size of a fifty pence piece. They really are lovely and colourful
with their Yellow crest for a female and for a male a Gold. This autumn has seen a significant
number arrive at Trimley and we have been able to ring a good number. It is hard to imagine such a tiny bird
travelling all the way from Scandinavia and the Nordic countries to spend
winter with us. Other tiny birds
that we have seen and ringed include Redpoll
and Siskin
Another
striking and colourful bird to make a visit this month is the Waxwing. We had 8 on the 12th November eating the
berries of Viburnum opulus just outside the visitors centre. Such exotic looking birds and there have
been good sightings around other areas of the county.
Visitors
to Trimley often hear the very melodic song of the Cetti’s Warbler. The shrubs by the visitors centre can
be a favorite singing post for this very distinctive little bird. However, it
depends on thick vegetation for its survival. The importance of Trimley reserve for this species as well
as other marshland birds is hugely significant. This autumn we have seen a good
increase in numbers on passage. We
have ringed at least 2, which will contribute, significantly to our
understanding and subsequently their survival.
Early
yesterday morning on a glorious sunny day and walking along the sea wall I
heard the call of the Kingfisher.
Today we had the privilege of ringing one. Looking at the colours of this beautiful little bird tells us
that nature is truly amazing.

Thanks to Ernie, Dave and John for
their hugely valuable counts and sightings.
