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)

A Record Day

Yesterday was something of a record day. We caught 4 Cetti's Warblers in one net line. We have only caught singles before of this recent colonist. Up to 5 or 6 birds have been singing at Leighton Moss RSPB Reserve. One assumes that our catch originates from these breeding birds. However last October we controlled a bird which had been ringed just 38 days previously at Wood Walton Fen in Cambridgeshire a movement of 299 km in 38 days. So you never know.

We also caught our third Yellow-browed Warbler of the autumn and 8 Siskin the best catch so far this autumn.

But the most unusual catch was of a pair of Bearded Tits with consecutive ring numbers. I was amazed to find that they had been ringed as nestlings in the same nest in April 2014. We have ringed 673 nestling Bearded Tits as part of our long term study of this species. Many have been retrapped as adults but this is the first time we have recorded siblings as an apparent pair. Our observations do suggest that Bearded Tits do form lasting pairs. Interestingly neither of these birds have been recorded on the grit trays over the past two years.
