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)

How good are you at ageing/sexing Twite?

The Heysham wintering Twite, with perhaps a mix of  larger north Scottish birds and smaller south Scottish/the odd Pennine bird are not easy to age/sex.  Have a go at these.  Wing length given as a clue/misleader.
