Brian,
From a couple of ringing sessions I would say it has generally been an excellent breeding season. At my woodland edge site, Whitethroats are everywhere and there are good numbers of Tit species, Chiffchaffs, Blackcaps and Bullfinches. At a garden feeder site juvenile House and Tree Sparrows have done well and Chaffinches were more prolific than ever. I will know more when our Ringing Group has collated all our records. For information, the BTO has been running the Constant Effort Ringing Scheme since 1983.
This involves ringing at about 120 woodland/reed/scrub sites (not gardens) throughout the UK which has provided invaluable information relating to demography and population dynamics. I took part from 1988 to 1997 at Occupation Lane (TF1291) which amounted to 720 hours of ringing!! Clear felling by the Forestry Commission meant that the habitat change severely affected the constancy so I had to give up. More information can be found at
