Two more Jetty visits and CES 11

In contrast to our modest reed-bed catches at Llangorse Lake, in the last 10 days or so, Goldcliff R Gp have had a catches of 136, 155 and 88 in the Uskmouth reed-beds - made up of almost equal proportions of Reed and Sedge Warblers, and with only a handful of other birds. The extensive reed-beds at Uskmouth, and the coastal location, both contributing to the numbers of birds that are caught. As well as having a larger breeding population, Uskmouth is now well established as a stop over site for migrating "Acros". It would be interesting to see what weight gains are achieved, but as relatively few birds are re-caught, this might not be easy to establish.Not to be deterred by Goldcliff's greater success however, Andy and Jerry were at the jetty on Tues 18th for a catch of just 16 + (1). Jeremy was there on Fri 21st, when the weather was drizzly and breezy, and he had an even lower catch of 12 + (2). At the jetty, where the nets are in constant view, and shelter is provided under the hide (or in the back of the car), we are able to cope with inclement weather conditions. In the garden however (where Jerry was undertaking CES 11), we wouldn't normally choose to ring in such drizzly conditions, but had no option as the forecast was the best of the upcoming days. The catch was undoubtedly effected by the poor conditions, and was perhaps Jerry's lowest CES ever, at 10 + (6) and by far the lowest of the year.

Species make up for the three sessions -
Wren (2)
Robin 1
Blackbird 1
Reed WArbler 11 + (1)
Sedge Warbler 11 + (1)
Willow Warbler 1
Chiffchaff 7 + (1)
Goldcrest 2
Blackcap 1 + (2)
Blue Tit 1 + (1)
Great Tit (1)
Treecreeper 1
Nuthatch 1
