The Data Builds Up

A recent batch of recoveries added a little more to our knowledge of the movements of birds in our area.

A Sedge Warbler originally ringed in Oxfordshire in July 2010 was found breeding at Leighton Moss. This is our first Sedge Warbler recovery from Oxfordshire. By contrast a Reed Warbler also found breeding at Leighton Moss and ringed at Icklesham in Sussex in late August was our 34th Reed Warbler in Sussex.

Sand Martins have been our most ringed species this year with 2101 new birds ringed. We received details of some of the 648 ringed birds we caught while breeding in the sandy banks of the River Lune. These added to the data we already have brings the total recoveries from Sussex to 117, 13 in Kent, 18 in Yorkshire seven in Cheshire but only our second from Wiltshire. Most have been caught at reed bed roosts but a good number have been caught roosting in established colonies as they make their way south,
