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 Flycatcher reacquaintence

Perhaps predictably, the first Pied Flycatchers off the mark with full clutches in upper Hindburndale were these two old stagers:

T367170 – This was ringed at Colleyholme Wood, nr Stock's reservoir, Slaidburn as a nestling on 10/6/08.  Its whereabouts during the 2009 season were unknown, but in 2010 and 2011 it nested in the same box – in Box 21 at the top of the wooded section of road between Botton Mill and Summersgill.  The current (2012) box is about 350m from Box 21.

V470146 – This was ringed at Wray as a nestling on 5/6/07.  Its whereabouts in 2008 and 2009 were unknown, but in 2010 it nested in Box 24 Botton Mill and in 2011 it switched to Box 25 Botton Mill.  .  It is currently (2012) in Box 36, about 250m from Boxes 24/25

I have not had time to check any other 'family tree history' of these two, but V470146 was the mother of X947707 in 2010.  This was a nesting female in Box 31 in 2011, but unfortunately deserted a hatched brood.  This was presumably due to it being predated, rather than all the young dying for another reason as there was no obvious food shortage/temperature problem affecting any other tit/PF boxes
