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)

Sand Martin recoveries

We've had another batch of Sand Martin recoveries and leaves just one bird we caught this year as having an unknown origin (well unknown beyond Spain or possibly Senegal anyway).

Once again France have excelled themselves and sent us details of two birds we caught:

Paris 6243026
Ringed 14/08/2009 Lentilles, Aube, France
Retrapped 11/07/2011 Arkholme, Lancashire 806km NW

Paris 6452590
Ringed 17/08/2010 Lentilles, Aube, France
Retrapped 26/07/2011 Alston Reservoir, 777km NW

While both of these are nice they are very unsurprising given the number of Sand Martins ringed in France and it is the only viable route to Africa for British Sand Martins. The bird caught at Alston is out of our normal area however was caught as part of a mission to see where the Alston colony had been populated from. The answer is clear - not the Lune valley!

Details of two birds we ringed as Juveniles at Whittington have also been sent through:
Ringed 29/06/2011 Whittington
Retrapped 01/07/2011 Weather Hills Pond, North Yorkshire 74km E

Ringed 14/06/2011 Whittington
Retrapped 26/06/2011 Whittington
Retrapped 01/07/2011 Weather Hills Pond, North Yorkshire 74km E

These movements once again show that Juvenile Sand Martins move very quickly. Y150440 moved 74km in 2 days while Y150149 did it in 5 days having stayed around for two weeks from ringing.

I have no doubt there are many more Sand Martin details to come through from 2011s ringing, hopefully with several in Senegal.
