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)

Godwit arrival dates

Black-tailed Godwit have started arriving in reasonable numbers at Leighton Moss in recent days.  Several of these have long histories of spring sightings at Leighton and other very local sites having spent the winter further south on the Dee.  Two are of note with several years of good arrival data for Leighton Moss.  The first seen date is listed below for each year they have been seen at Leighton:







It would be very easy to say 'global warming' or 'unseasonably hot weather' is driving the early arrival date however I think it's more complex.  This winter has been fairly dry and many of the sites used early in spring by these birds (Lytham Hall, fields on the field) are only good feeding in wet conditions so maybe the early arrival is more a case of lack of good feeding throughout the tidal cycle rather than an early migration north.

Thanks to all the observers at Leighton Moss for seeing and reporting these birds to the ringers (in this case in Iceland).  The arrival and departure dates are really useful so even if the bird was seen yesterday reporting it again is important to understand how the Godwit use different landscapes in a changing world.

Our Nuthatch Study

We have continued our colour ringed study of Nuthatch visiting Jerry and Barbara's woodland edge garden at Silverdale. They usually see no more than two birds visiting their feeders at once but since late summer 2018 we have seen or caught 19 birds. In January at least 11 different birds have visited the feeders. They basically fall into three categories based on our sightings.

There is obviously a resident pair which have each been seen 14 days,very often together. Three other birds have been seen less often but still regularly  probably from adjoining territories close by. But the remaining six are only infrequent visitors only being recorded once or twice a month but obviously attracted by the abundance of bird food on offer. One assumes that they have territories some distance away in the surrounding woodland.
