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)

Our Ringing Suggests Excellent Productivity

2014 is turning out to be a record year for the group. Although helped by the excellent ringing weather in September our ringing totals so far this year  for warblers especially, are the highest on record . The table below compares our catch this late summer/autumn with the  averages for the past 10 years from three of our regularly ringed sites where effort has been similar over the years

                                              Average Catch                   2014 Catch
Chiffchaff                                      132                                409
Willow Warbler                             280                                541
Blackcap                                         65                                 244
Whitethroat                                     77                                 243
Reed Warbler                                602                                 916
Goldcrest                                        87                                 139
Robin                                              96                                 255          

For the last two residents the average catch extends to December so the 2014 figure should rise. The only warbler that we ring in significant numbers not to show an  increase was Sedge Warbler . Here the catch at 438 was around average.

Lesser Whitethroat can also be added to the plus list with 60 new birds at Middleton/Heysham well above average
