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)

Out Of Bounds Dipper
This superb photo of a colour ringed Dipper was taken by David Talbot on the River Kent in Levens Park on January 10th during the height of the cold spell. We have tracked it down to one ringed by Peter Mawby in his Dipper Study area which is centred on Sedbergh where he ringed 123 nestlings last year.
Although the movement is only about 16 kms it is the first time a Dipper has been recorded moving from the Lune and its tributaries to the Kent. Peter suggests that it seems probable that this winter's severe weather caused more young birds to move away than usual. He also reports that on recent visits to Sedbergh that the breeding territories are only very slowly being occupied. This time last year, despite the cold spell, nesting was well under way.
The BTO Migration Atlas shows that the average dispersal of young Dippers is only about 2.5 km and invariably within the same river system so this Dipper is quite unusual.
Peter would be very grateful for any other sightings of colour ringed Dippers. Please report them to this site.
