Now Where Did YOU have Christmas Dinner?...

News has come in from Adrien Pajot that he has re-sighted one of our brent, 2IRR (2 right leg, I left leg, R ed right leg-ring colour, R ed left leg-ring colour) on Christmas Day, on the western tip of the Île de Ré, Charente-Maritime, France. For those of you who are equally geographically challenged to myself, this island, which is connected to the mainland by a bridge, lies about half-way down the western coast of France, near La Rochelle, on the Bay of Biscay.

This record is from near the southern limit of the range of our birds, and only two ringed birds have ever been recorded from as far south before - CIWW visited the nearby Île d'Oléron during the 2005 / 2006 winter, and HPRY was recorded from Île de Ré in February 2011. Both birds were subsequently recorded from Ireland in subsequent winters, so the extra flight and sun-tan doesn't seem to have done them any harm!

2IRR was ringed in 2013 as part of the intensive series of catches in the Dublin area which have been going on in the past few years. This winter I had it passing through Strangford Lough in late September, following which it was picked up by Pat Watson at North Bull, Dublin on 03 November. Just over a week later, it was recorded from Havre de Regnéville, in Normandy, the main French site for our flyway, on 11 November, by Jerome Bosec. It was recorded there a couple of times again by Alain Livory and Roselyne Coulomb, for the last time on 14 November.

So, this bird has been passed on from one observer to another right along the flyway, which I guess is one of the fascinations of being a ring-reader!!

Having been laid low by a number of fairly vicious bugs over the Christmas period (and apologies that this has led to fewer updates on things), I'm hoping to remove myself to County Donegal tomorrow to seek out a few more new rings at less well-covered sites there over the New Year. Season's Greetings to everyone!!


PS Collation of the early November Census is nearly complete, and I would hope to be able to come back with the findings on my return!

Site Faithfulness Across the Flyway...

I've just been working on the latest overall Summary which I send out to observers of marked birds, and, despite it being relatively early in the winter, already the re-sighting pattern is following that of other winters since 2007, when the Group first ringed birds on the breeding grounds in High Arctic Canada. Detailed study by our colleagues at University of Exeter, and particularly Xav Harrison, has shown that groups of birds and families tend to use the same specific sites throughout the flyway path i.e. breeding, through migration to their wintering sites.

Hence, I thought it might be worth sharing that, already, about 10% of the birds which we ringed this summer up on Axel Heiberg Island (look it up on Google Earth!!) have been recorded from one small estuary in Ireland, at Rogerstown, just north of Dublin. The recent photographs below are courtesy of Christer Persson, of birds located at the entrance channel - the second one is looking out towards Lambay Island, which the brent from Rogerstown (proven by records of ringed birds) also use on occasions.

And Now the Other One...

The second bird I referred to in yesterday's blog was S6WR, an adult ringed at Greyabbey, on the eastern shore of Strangford Lough on 24 October, as part of a catch of 7 birds.

At Greyabbey, inter-tidal is particularly difficult, as we are depending on the tide flooding up to a HW spit, and any catch involves a mad tidal dash by the team across to the net in waders! The birds can be very fickle from day to day, illustrated by one of my recce (as usual, VERY poor quality!!) shots on a non-attempt day, which makes one wonder how we can catch only 7 geese!! C'est la vie!! And we always catch less than we hope for there!!


So, having set the scene, unlike the bird yesterday, which went south, this bird headed east and north, to the Solway Firth, Wigton Bay in SW Scotland, to be more precise, where it was picked up by Derek Farr, and reported in to us.

So, again, a lot of effort, but it proves that even small catches at this stage of the season can yield very interesting results, as these birds are merely staging on Strangford Lough! As with the "Lone Ranger", we are indebted to canon-netter Stuart Bearhop (the Prof!) from University of Exeter, the rest of the team from there, and those who turned up to help with the catch.
