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, regular readers may have noticed the increase in posts detailing wildlife found across the valley (ranging from plants, fungi, butterflies, dragonflies & other invertebrates). Ringing posts will hopefully resume over the winter months, and will run alongside wildlife and work posts.

28/03/12 - Norway...? No way!

This week we received a brilliant record from our friends at the WWT - one of our Whooper Swans ringed in the valley in 2008 has been sighted in Norway! Full details below:

W24882, ringed as a 4 (adult) on 30/11/08 at North Duffield Carrs, recovered on 26/03/12 in Sandsoya, More & Romsdal, Norway (field sighting).

This is the first record we’ve had of one of our birds to Norway, with the majority being previously recovered in Iceland. The bird was first ringed in the valley in November 2008 after a cannon net catch at North Duffield Carrs which resulted in 18 birds caught thanks to expert judgement from Mark Fletcher. K3H was later seen throughout January, February & March 2009 by Janet & Peter Roworth (Senior Reserve Manager at the time - now SRM at Saltfleetby-Theddlethorpe Dunes NNR). After leaving the valley in 2009 it hasn’t been seen since, until now!

Whooper Swan 'K3H'


History of ‘K3H’: Ringed as an adult on 30/11/08 at North Duffield Carrs, it was then sighted early at the start of 2009 on the 3rd, 6th & 8th of January, still present  at N.D.Carrs in February (seen on 19th & 26th) and last recorded in March on the 7th & 16th.

On the day that K3H was caught and ringed, so were 18 other birds (all fitted with darvics), and out of those we’ve had recoveries from 3 individuals to Iceland (listed below), and a number of the other birds have also been seen during subsequent winters throughout the valley.

In total 45 Whooper Swans have been ringed in the valley, in addition, 26 have been ringed elsewhere and sighted within the LDV. Out of the 45 ringed here, 31 have been re-sighted subsequently, including 11 away from the valley. The data has produced a total of 21 exchanges with Iceland and single movement to Denmark, making this the first of our birds to be reported from Norway!
