Welcome to the LDV NNR ringing blog, this blog is designed to share the experiences, findings and tales from a group of dedicated ringers. We specialise in conservation orientated research projects, largely focusing on wildfowl, waders, owls and birds of conservation concern, in and around the Vale of York NNR's.

NB - Whilst the purpose of this blog was initially designed to cover our nationally important wildfowl ringing activities, it now also features wildlife and work posts, explaining we how manage the NNR for both wildlife and people.

05/10/17 - Recoveries

Migration is very much in evidence in the LDV at present as the first of the incoming winter visitors start to arrive. Our ringing studies have already shown a link between the valley and 25 other countries as well as information on movements within the UK. Recent recoveries include a young Reed Warbler that was ringed at Wheldrake Ings on the 5th August, moving 381 Km to the south to Fleet, Dorset in just 11 days on the first leg of its migration. A Lesser Redpoll ringed near Melbourne in November 2015 was re-trapped by ringers in Scotland, at Carluke, South Lanarkshire, 277 Km to the north just a couple of weeks ago. 

We’ve also just heard that one of the Herring Gulls colour-ringed at the local landfill site in February this year, was re-sighted off a trawler in the Barents Sea, Arctic Ocean, 2500 Km away, showing that our ‘local’ birds aren’t quite as local as we might think. 

We’ve been fortunate over the last 20 years to ring 40 Ruff, the results of which have revealed much about their complex lifestyles and movements, and this week we received another such movement. An adult male, ringed in January 2015 as part of the resident wintering population at North Duffield Carrs, was unfortunately found dead on the breeding grounds at Tranøya, Senja, Tranøy, Troms, Norway, 1950 Km to the north-east of the valley. This is the eighth international exchange we’ve recorded, and our second movement between Norway, with a single bird from Sweden and five exchanges between the Netherlands also recorded, showing just how international our ‘local’ birds are. Up to 27 individuals are back in the valley now with numbers often peaking around January and February with over 100 birds.

Please let us know if you come across any colour-ringed birds in the valley on here or by leaving sightings in the hide log books provided, thank you.
