Ringers: LL,CMS,CK,GK
Weather: Westerly 10 - 15mph, cloudy
With the forecast for the rest of the week looking very unsettled we took the chance to get CES 6 done today. Glad we did because despite the wind, threatening showers and a worrying mid-morning lull, we had a good session with 83 birds caught and 80% of them juvenile - demonstrating that the breeding season is going very well.
With four of us there the nets went up quickly and although the first net round was quiet, at 5:30am we had a good round of mainly young chiffchaffs and blackcaps but also juvenile robins, wrens and blackbird.
We had another juvenile reed bunting side by side with an adult male which we colour-ringed. Hopefully we will be able to re-sight these birds at the reservoirs over winter.
We caught our first young reed warblers, a second juvenile cetti's warbler and another six young wrens. The wren's nest we are monitoring is nearly ready to fledge so we are promised more next week!
The reed bed is now nearly at full height and the rides are full of marsh bedstraw and there is water figwort coming into flower.

At around 9am it started to go quiet and for a while I thought it was going to be a disappointing total but just as we started to think about taking the nets down we were hit by a lovely flock of young tits, chiffchaff and our first young goldcrest. Twenty nine birds in the last round brought the total up to 83 which is well above the average of 60 for CES#6.
