Sunday's forecast and commitments elsewhere, meant Gary and I gave Granby a go today. We had the three Cs, calm, cold and clear weather, though the breeze did build up without any appreciable impact on the catching. A Tawny Owl flew across the bonnet as we drove up to the lengthsman hut.
The 3Cs gave up good conditions for catching 'keen' birds, and we processed 102 individuals. Pleasingly, Yellowhammers made up nearly a third; our best total of the winter so far. As often happens after Christmas, there was an influx of new tits amongst the retraps.
The majority of the retraps were from last winter, bar Blackbird and Yellowhammer from 2012/13, Blue Tit, Chaffinch, Robin (2) and Yellowhammer (2) from 2011/12 and Blue Tit and Great Tit from 2010/11.
Total captures were (new/retrap) 102 (59/43): Blackbird 3/1, Blue Tit 9/12, Chaffinch 10/5, Dunnock 2/1, Great Tit 6/12, Robin 3/3, Tree Sparrow 5/0, Wren 0/1, Yellowhammer 21/8.
