I
went to Longshaw with John G this morning hoping for another good catch of Bramblings
and Chaffinches. I had been keeping the site well fed all week and the weather
forecast was good for this morning at least. We had 3 nets up by first light
but when the first birds started to arrive it was quite clear they were fewer
in number compared to the last few weeks.
Catching
rates were slow and were not helped by frost forming on the nets. This turned
them white for a while until the sun rose above the tree line. We packed up at
around 11am having only caught 23 new birds and 12 retraps, around a third of
last week’s total. Only 2 new Bramblings were caught along with 12 new Chaffinches.

I
decided to go to Haigh this afternoon as the wind was still very light and the
forecast was for much stronger winds tomorrow. John had better things to do so
I went alone and had two nets set up by 12:50 which is usually a quiet time of
day in ringing terms. There were plenty of birds about and the ringing totals
didn’t disappoint in sharp contrast to Longshaw this morning. A total 21
Bramblings were caught including 2 retraps. Interestingly one of these ‘retrap’
Bramblings had actually been ringed at Longshaw on 18/11/12; a movement of 9km
northeast.

Short
distance movements such as this are interesting in their own right. I have been
feeding both sites equally well and there are other feeding stations closer to
this bird’s ringing site including Kings Moss on the other side of Billinge
Hill used by Pete Fearon (blog here). It makes sense for wintering birds to
familiarise themselves with food availability over a fairly wide area. This will
enhance their chances of survival should any one food supply become exhausted as would
happen with natural food sources. It will be interesting to see if there is
more interchange between sites over the winter.
One
thing that has surprised me is how well we have done for Bramblings
relative to other feeding stations in the northwest. The ringing total now stands
at 144 Bramblings for this winter but, clearly, the birds are still moving
around and numbers at other sites are likely to increase as the winter progresses.
A
single Siskin was caught and was the first for the winter at this site; it was
an adult male and a little gem. It had found the nyger feeders and it is hoped
many more will follow before the winter is out. The ringing totals were
excellent for an afternoon but could have been even higher as the session was
curtailed at around15:30 when drizzle arrived.
