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)

Which Way Africa?

A recent batch of recoveries from the BTO included details of three Sedge Warblers. Two juveniles ringed at Leighton Moss took the expected southerly direction. One ringed on 23 August was caught just 12 days later at Orfordness in Suffolk a distance of 372 km SE. The other ringed 1st September turned up 15 days later in a net at Titchfield Haven Hampshire 387 SSE. Nothing unusual in these two for we have had 69 previous recoveries of Sedge Warbler from late July to early September in Southern England. The recovery locations, almost all of them controlled by ringers, ranging from Cornwall to Suffolk and all counties in between.

But Y223110 was different . It was ringed on 23 July 2011 at Belvide in Staffordshire and caught at Middleton NR just 26 days later on 18th August, 154 kms NNW. Its our first example of reverse migration in this species. This regularly occurs in a number of species, ringing has shown that some at least retun to the usual migration route.
