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)

Pied Flycatchers Record Year

Now got all the data in for our Pied Flycatcher RAS for the 18 woods we survey in the Lune Valley. We have a record 98 occupied nest boxes 19 up on last year and 8 more than our previous best year of 2015.
To date they are doing well.We visited nine nests yesterday all had young and seven were old enough to ring with an average brood size of 7.2 including two with eight young.Have got the first details of the adults that we have caught. They show the usual pattern of adults mainly returning to the same wood in successive years but birds ringed as nestlings mainly move away from the natal wood to other woods in the Lune valley with a few moving outside our area. The two extremes from past years were birds found breeding in Denmark and Germany after being ringed as nestlings in our boxes.
We have many broods yet to ring hope that the heavy rain forecast for early next week doesn't harm them.
