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)

Reed Warbler Progress Report

Our Reed Warbler RAS (Re-trapping Adults for Survival)at Leighton Moss is going well. To date we have caught 71 adults. Of these 43 were already ringed in previous years. The breakdown when first ringed is detailed below-

Year of Ringing Number
2002 1
2004 2
2005 2
2006 3
2007 12
2008 9
1009 19

Of the 19 from 2009 seven were ringed as adults and 12 as juveniles.

The oldest bird is eight year old with the two 2004 birds both ringed as adults so are at least seven years old. Our oldest Reed Warbler to date was just short of ten years.

This is the 14th year of our study and we average around 165 adults a year but with the rest of June and the whole of July yet to go it looks as though we are on track to achieve this total. Most adult birds have left by the middle of August.
