What a difference a week makes

At Stanford Reservoir, Northants our CES 5 on 18th June produced just three juveniles out of a miserable total of 30 birds which was more than likely due to heavy losses after an almost entire week of torrential rain leading up to the weekend.
CES 6 yesterday was a completely different story with a total of 105 birds processed throughout the day. However, only 58 contributed towards CES.
Of those 58 CES birds, 41 were juveniles and 17 were adults. Highlights of the day were this years first juvenile Willow Warbler, Sedge Warbler, Blackcap, Garden Warbler, Grasshopper Warbler and Goldcrest.
Unfortunately we were rained off an hour early and with everything soaking wet and all packed up decided to visit the dam for a look around. A family of Grey Wagtails were feeding on the pond weed in the outflow so we decided to set up a 20' across the channel and see if we could catch some.
Two juveniles of both Pied and Grey Wagtails were caught although the adults proved far too net-wary. A Mute Swan caught by hand on the dam ended a rather damp but productive morning.
