Update for Brackenhurst & Granby ringing efforts

Just a quick summary of recent visits to the feeding sites at Brack and Granby. They've been characterised by low catches due (I guess) to the unseasonably mild and windy weather we've been experiencing, perhaps combined with poor breeding over the last year or so. Certainly Yellowhammer totals will be down by a third this year. Positives have been:
  • Ringing early migrant Chiffchaff and Willow Warbler. 1st April could be the earliest date the Group has marked this species?
  • Clearly all the Great Tits are settled on their territories as all 24 birds were ringed!
  • Nice to ring what appears to be resident pair of Treecreepers at Granby.
  • Time at Granby for Gary and I to burn some more of the brash, helping the Grizzled Skippers.
  • Getting back into ageing Chiffs with three in the hand together.
Totals for individual species (ringed/retrapped):
