Three RAS sessions

During the last week, visits have been made to three reed beds for our RAS Reed Warbler study. 
On Monday 19th June, Andy and Jerry completed our first visit, to a new site near the Sailing Club.  It was a bit disappointing, with just 11 birds ringed, and no re-captures, but is expected to improve when there are more juvenile birds active. 
On the evening of Tuesday 20th, Carlton tried the jetty, and had a catch of 17 + (9).  There were a few Swallow/Sand Martin about, but he failed to attract any to the tapes/nets. 
The following morning, Alan L continued at the jetty, with 16 + (3), while Andy and Jerry were in rb2, for 23 + (14).
Wednesday was forecast to be the last day of the recent heatwave, and future visits could see netting conditions improve. 
A summary of species for all of the catches - Wren (1), Blackbird (1), Robin 2, Redstart 1, Cettis Warbler 1, Reed Warbler 30 + (18), Sedge Warbler 1, Chiffchaff 8, Garden Warbler 5, Blackcap 3, Blue Tit 7 + (3), Long-tailed Tit 2, Treecreeper 1 + (1), Bullfinch 3, Lesser Redpoll (1) and Reed Bunting 3 + (1). 
The Reed Warbler recaptures included an additional seven individuals for our RAS.  The Cettis Warbler was a juvenile bird caught at the jetty.  The Lesser Redpoll was a female (with good brood patch), in rb2; this species is rarely caught by us during the breeding season, and had been ringed, as a young bird, in the garden, in Nov 2016.
