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)

Ringed Arctic Terns

During the easterlies this last few days it has seemed like the whole northern European population of Arctic terns has been dropping in to feed on Heysham Power Station outfalls before heading off north-east!

Yesterdays phenomenal minimum of 8,153 birds included a group of about 80 resting on the beach within ring"examining" range

They included 5 with what were presumed to be British C2 rings and these obviously contrasted with 3 birds bearing bulkier rings. Potentially the most interesting was one which initially appeared to have metal rings on both legs. On 50 x, this appeared to be a "long white ring" with some inscription on the right leg and a 'bulky' (c/p C2) metal ring on the left leg. The only possibility on the Dirk Raes site is one from a Dutch RAS scheme. Odd? - until you note the 50 Black Terns accompanying these birds

Are a proportion of these Arctics also overshooting? We will never know - if only they had been 50 metres on so closer!
