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)

Which Way Africa?

A recent batch of recoveries included the first two from our ringing of 1440 Swallows this year mainly at a roost in a maize field.

The first one from Hampshire, 389 km to the SSE just 19 days after ringing in early September, was obviously heading in the right direction. The other though was ringed as a nestling on June 12th this year near Hoylake on the Wirral. It was caught in our roost 79 days later and 88 km to the NNE. This is not the first Swallow we have had to show a northerly movement at a time you would expect them to be heading south. A nestling ringed in Staffordshire on 10th June 2005 was controlled in our roost on 30 August the same year and 191 km to the north. Perhaps even more surprising was a juvenile ringed in Lincolnshire on 26th August 2004 and caught four days later in our roost 186 km NW.

This type of movement has been recorded in a variety of species. Members of our Group who take part in vis.mig. watches tell me that N and especially NW movements of Swallows in some numbers have been recorded in most recent years and is often linked to unfavourable migration weather.
