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)

Early Population Indications

One of the great things about reasonably standardised ringing is that it gives you some insight into the productivity of the most frequently ringed species. It's early days yet but there are a few indicators from our two regular ringing sites in the Silverdale area. Two species stand out -Treecreeper we have already caught 29, the best we have ever achieved in a full year was  27 and weve still five months to go. We have already also caught 29 Long-tailed Tits two more than in the whole of 2017.

Of the species ringed in larger numbers Willow Warblers are doing well with 110 ringed and the best period for passage yet to come. We have caught a good number of moulting adults. After a slow start both Reed and Sedge Warbler are doing well. I feel that both these species  had a protracted arrival this past spring and this is reflected in an extended breeding season with numbers of young coming through now. Blue Tits and Reed Buntinga are well above average so far this season. The only regularly ringed species which appear to be lower than usual are Goldcrest  and Wren.

One further thought, in this very dry summerr with many streams and pools dry, both our sites still have water which may be proving attractive and rather inflating numbers around our net sites.
