Chew Valley Ringing Station

is located in North Somerset just north of the Mendip hills on the southwest shore of Chew Valley Lake and on the A368 road midway between Bath and Weston-super-Mare, between the villages of Bishop Sutton and West Harptree.
Ringing started at Chew Valley Lake in 1963 and the first report was produced by the Mendip Ringing Group covering the years 1962-63. Our ringing area is mainly reed bed with some scrub. Between April and September we normally catch good numbers of Reed Warblers and Sedge Warblers and a varying number of other species such as Blackcap, Chiffchaff and Willow Warbler plus the normal residents which now include Cetti's Warbler. We get a good passage of migrants and there is plenty of chance to see stages of moult. We also attempt to catch hirundines at roost.
If you wish to enquire about membership or have any other query please email us at cvrsringing@fsmail.net in the first instance for details.
