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)

July Update

With the rain beating down and the wind blowing and a poor forecast for the next two days  it looks as though our ringing is finished for this July. Time to take stock and compare with last July's ringing in our RAS studies  at Leighton Moss RSPB reserve. Its so easy to do this  with IPMR. We managed 16 ringing visits this July, two more than in 2012.

Bearded Tits have done well with 32 juveniles compared with just 17 last season. The most intriguing increases though are Blackcap with only 14 last year but 50 this July and Chiffchaff increasing from just 6 in 2012 to 46 this year. Willow Warblers after a good start have slipped back recently  and we caught 83 in both years.

Sedge Warblers have done well with 91 compared to 39 last year. Reed Warblers though are down from 261 to 202. Whether this reflects a population decline or just a late start to the season only ringing in August may reveal. Interestingly we caught two adults in the last week showing signs of preparing to start their return migration, one weighed 13.1 grams, with a fat score of 3 and the other 12.4 and a fat score of 2. From past ringing we know that return migration in this species starts in late July, for we have had 5 adults caught on migration on the south coast during the last week in July.
