Ringing recoveries

Hello

Some recent ringing recoveries have been received as a result of Northants Ringing Group activities as follows:-

1. A first year Garden Warbler was caught and ringed at Beachy Head, East Sussex on 16th August 2017. This bird has been caught three times at Pitsford Reservoir this month on the 4th, 6th and 16th when assessed as being a breeding female. It is about 194 km between the two sites but of course she has been to Africa and back on two occasions inbetween!

2. An adult drake Mallard was caught and ringed at Pitsford Reservoir on 24th July 2014. This bird was reportedly shot between Kopnino and Svechino, Perelavik, near Moscow in Russia on or about 26th April 2019. The distance from Pitsford is about 2578 km in a general east direction, 1737 days elapsing between the two relevant dates. Catching adult Mallard at Pitsford in the summer is not in itself remarkable but most of our recoveries of these birds relate to birds shot locally and we have never had a bird travel so far away. The origins of this bird are not known - was it a Russian bird summering and moulting here in 2014 or a British bird deciding to travel east?

3. A first year Reed Warbler was trapped and ringed in Spain at a place called Balsa Guarda, Bardenas near Navarra on 19th August 2017. This bird was caught again at Stanwick Pits/Lakes on
22nd June 2019 when assessed as an adult male. This is another bird that between these records has wintered on two occasions in Africa - it is about 1119 km north between the ringing and recovery sites with 672 days elapsing between both episodes;

4. A first year male Goldfinch was caught and ringed at Astcote, Towcester on 24th November 2018 and 242 days later was found dead and wedged in a radiator grill of a car at Dunbar, East Lothian on 24th July 2019. This record mirrors many other Goldfinch records indicating that many Scottish breeders winter and pass through Northamptonshire.

It is hoped to commit to some bird ringing at Harrington Airfield this coming Friday and Saturday and if anyone wants to come along to observe proceedings please let me know. This will ensure that access to the old airstrip and bunkers will be restricted to members of the ringing team and invitees (conditions imposed by land owner). Access to the concrete track and footpaths remains unaffected.
