While ringing at Rostherne Mere, Cheshire, Malcolm Calvert from South Manchester Ringing Group, was amazed to catch a Cetti's Warbler! This species has been moving steadily north over the past few years but is still considered very scarce in Cheshire.
V297794 was ringed at Upton Warren, Worcestershire as a juvenile female by Wychavon Ringing Group on 18/07/2009 and when Malcolm caught it it had a fully developed brood patch and then on the 2nd July he caught a recently fledged chick. This is a very valuable breeding record for this species for the Bird Atlas. This is the second breeding record for the county!
This bird was part of a colour ringing project which is used to monitor the movements of birds without having to catch the bird, so people that don't ring birds can play a part in this monitoring.
The map below clearly shows the northward movement of this bird.
