NLRG was formed in 1957 to help in the study of birds in the Lancaster and District Birdwatching Society area. There are currently 12 active ringers. Species currently being studied include: Pied Flycatcher, Bearded Tit, Sand Martin, Twite, Goosander, Oystercatcher and Grey Wagtail. Migration has been studied for 28 years at Heysham. We welcome anyone who wants to observe, help or perhaps wish to become a ringer. Photo: A Heysham-ringed Twite on the Mull of Kintyre (thanks to Eddie Maguire)

Long Lived Reed Warblers

This week we have caught a Reed Warbler at Leighton Moss which was first ringed there on 23/07/01. that makes it 7 years 342 days since ringing, almost 8 years. However it was an adult when caught so it is at least 9 years old. The oldest Reed Warbler the group has recorded to date was 10 years old. The oldest Reed Warbler recorded by the National Ringing Scheme was 13 years- so our bird has a bit to go. The interesting thing is that it had never been retrapped during the 8 years until this year.
We have also had two other long livers this spring at 6 years and 302 days and 5 years and 309 days. These two birds have also not been regularly re-trapped. They have obviously breeding away from our ringing rides. This year though much of the reedbed was seriously trashed by the roosting Starlings so there may well have been a re-distribution of breeding birds.
