Brackenhurst, Wednesday 28 December

As often happens there was a cold snap betwixt Christmas and New Year. Duncan, Kev, Tom and I took advantage of this on the 28th. It was still and frosty when we arrived before dawn and freezing fog came down at nine, but soon to be replaced by bright sunshine ‘til we left.

The first net round produced about 30 birds; mainly Redwing and Yellowhammer. The latter formed nearly half of the catch with the oldest retrap being a bird from just over six years ago; this Yellowhammer had not been caught between times. The old birds often show up at the feeders in cold weather, and we also had Yellowhammers from 2013 (2), 2014 and 2015 (2). The oldest bird retrapped was a Chaffinch from 2009. As with Yellowhammers, Robins are apt to show up at the feeders in cold weather and we processed 10 birds with retraps from 2013, 2014 and 2015. Its almost like the older, more experienced birds know where to look for food when its cold!

The total number of birds processed was 87 (54 new/33 retrap), comprising: Dunnock 0/1; Robin 5/5; Blackbird 3/1; Fieldfare 1/0; Redwing 7/0; Blue Tit 2/6; Great Tit 1/8; Treecreeper 0/1; Chaffinch 5/1; Yellowhammer 30/10.
