More Goldcrests on the move.

There was a brief lull in the unsettled weather this morning so I headed up to Billinge to make the most of the calmer conditions. I set 3 nets in the top willows but used a different net configuration to the one I have been using recently as the breeze was due to strengthen from mid morning. It would have been a fairly quiet session but there was a rush of birds about an hour after sunrise that boosted the totals and accounted for nearly half of the 50 birds that were caught over the course of the morning.

The catch was dominated by Goldcrests (19) and Chiffchaffs (14) as is often the case at this time of year and one of the Goldcrest, a 1cy female, was a control (a bird ringed elsewhere). I suspect this Goldcrest may have been ringed on Walney Island (68km NNW of Billinge) as the ring number was fairly close to one I have had from there before, although that is only an educated guess at this stage and I will only know its origin for certain when the recovery report comes through. The best of the rest were a Grey Wagtail, the first Willow Tit for a while and 2 Yellowhammers.

There were a few more Meadow Pipits moving overhead than there have been so far this autumn but it was still not much more than a trickle and petered out as the breeze picked up. A few Reed Buntings were also on the move early on and was the first obvious movement of that species this autumn and resulted in 3 being caught. However, it very much had the feel that the weather was holding up diurnal migrants and more would have been moving had the conditions been clearer and the breeze hadn't increased so much.

Ringing totals (retraps/controls in brackets) for 10/09/17 were: Goldcrest 17(2); Blue Tit 1; Great Tit 1; Willow Tit 1; Long-tailed Tit 1; Chiffchaff 13(1); Willow Warbler 2; Blackcap 1; Wren 1; Grey Wagtail 1; Chaffinch 1; Greenfinch 2; Yellowhammer 2; Reed Bunting 3.
