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)

Ring more Great Tits!

A Great Tit ringed in Winder Wood, Roeburndale as a pulli last year was retrapped near Wray (also Roeburndale) at the weekend.

It might not sound too earth-shattering a question, but where do the Great Tits all go in winter? Winter observations suggest the aren't present in the upland woods, but they aren't retrapped elsewhere in the same way as Blue Tits (which can show surprising movements from the Lune Valley woods to lowland urban areas.)

So if they don't move, and if they don't stay in the upland woods ....... what do they do?

perhaps its time to question the old assumptions ... or to return to the hibernation hypothesis!

maybe we might learn something by ringing all the pulli we can find!
