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)

Further Evidence of an Excellent Breeding Season

I have already reported about the good productivity of our nest box schemes,  now our ringing sessions provides further proof . A  further visit to Jerry and Barbara's garden brought the total Great Tit catch  for the month to 81 which compares to  last years total from August to April of 85! Blue Tits were 91 compared to 153 in the whole of last season. Great Spotted Woodpeckers an amazing 21 one short of last seasons total and Bullfinch 24 last month compared to  only 21  last year. All proof of an excellent season with almost all of these birds being juveniles.

At our reed bed site at Leighton Moss  because of poor weather we visited in July on four less occasions than in 2012 but allowing for this Willow,  Sedge  and Reed Warblers are all well up as  are Blue Tits. Blue Tits are interesting, the percentage of adults in last seasons catch was17% this year it is only 2.5% a sure sign of good productivity.

Just got the results of our Pied Flycatcher RAS in the Lune valley. We  ringed 483 nestlings which is 163 up on 2015 even though the breeding population was ca 10 pairs lower this year. and there was high predation at two sites.

Will be interesting to see if this good productivity results in good ringing catches as the season progresses .
