With abysmal weather forecast for the next few days we took our chance and monitored Wraysbury while we could. Total amounted to 90 birds in all, mainly Whitethroat, Garden Warbler and Blackcap with a smattering of Willow Warbler, Goldcrest, Chiffchaff and a Lesser Whitethroat.
Only a few migrants had hung arounD to be retrapped, but S415109, a Garden Warbler provided some interesting information. This bird had been ringed at Broadwater on 29th July weighing 15.9g, was caught on August 1st at Wraysbury weighing 18.4g and after a week feeding at the Wraysbury site weighed 23.1g by 8th August. We don't expect to see this bird again as it will be on its way very soon - fat 6, muscle 2.

A calm evening before a few days forecast for very strong winds and intermittent showers. The four nets were up by 7pm. There were a few Reed Warblers, adults included, from the reed-bed and the track net provided approx 10 birds from the initial round. The total was much inflated by a flock of birds that passed through the track net, mainly Long-tailed Tits with a few other birds. The flock was some 40 strong and we captured about half of them.
As usual, the prospective roost promised much with quite a few hirundines making pre-roost circuits overhead, before the bulk of them moved off in the direction of King George reservoir.We did capture a few at the end of the day, but many more deserted us at the end of the day.
