Fieldfare and Siskins Return

Another week and another two sessions on Leith Hill producing another wealth of Redpolls (a cracking adult male Common below).  Wednesday being the first non-foggy day for almost a week and a half produced another 39 with a supporting cast of four Chaffinch which seemed to be of northern origin and a few Goldcrest - including a first year male with a huge wing length of 58.5mm, well outside the accepted size for this species.
The second visit yesterday morning was much more productive with 101 new birds which included 12 Goldcrest and 43 Redpoll, but was highlighted by a Great-spotted Woodpecker (below top two), my first Fieldfare of the year (below bottom three) and 22 Siskin.

The woodpecker is an obvious first year bird and is showing a huge amount of bleaching and wear on the older feathers.  The Siskins were a real surprise as there have been very few about recently and I have only caught 12 since the beginning of October (seven new and five retraps).  They were all coming to nyger which is usually not started in earnest until the New Year when the natural food starts to become scarcer.  Only the next few weeks will tell!

Also today another control Redpoll was caught Y439009 and the following recoveries were received:

Y443956 - Redpoll ringed on 29.10.11 at Queen Mary Reservoir, Surrey and controlled on 16.11.11 at Leith Hill 18 days and 27km SE later.

DHC979 - Goldcrest ringed on 16.10.11 at Hardham, Sussex and controlled on 17.10.11 at Leith Hill one day and 29km NE later.  This was a great movement for such a little bird in just one day, and seemingly in the wrong direction for autumn migration!

Common (Mealy) Redpoll - 65
Lesser Redpoll - 3
Redpoll sp. - 14
Chaffinch - 5
Blue Tit - 12

  1. Leith Hill is turning out to be a fantastic ringing site, Sam. Keep up the good work.
