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.

This is actually the first Garganey to be ringed in the UK since 2012 (when we last ringed one here), so we’re hoping that an eagle-eyed birder may spot it on passage somewhere. If you haven’t seen a Garganey yet this year you haven’t got long left – they often leave in August, however at the moment one is still present on the pool at Wheldrake.

The Sparrowhawk was a second-year male – moulting from its juvenile brown plumage and acquiring its fresh new grey adult feathers - good to know it survived that all important first hard winter. We have had a few recoveries of local Sparrowhawks, including one ringed in October 1977 in Dumfries and Galloway - found in Wheldrake in February the following year – a distance of 203km. It’s certainly been a good breeding season for many of our small passerine birds, so it’s safe to say that our Sparrowhawks will no doubt be enjoying a good year too with plenty of prey available.

Several days after trapping the Privet Hawk-moth (above), we were then delighted to find a Pine Hawk-moth in the trap early one morning (pictured below) - a new species for the reserve this year, and one which isn't always annual.
As well as many species appearing in good numbers over recent weeks, we have also recorded several scarcer species for the reserve. During recent years we have recorded just singles of the rather stunning Oak Eggar moth, which is attracted to our light trap at Bank Island. However, this year we have already recorded six of these large and impressive moths. The Oak Eggar, surprisingly given its name, does not feed on Oak, but instead actually got its name from the fact that its cocoon is acorn-like in appearance. The food plants of the caterpillar are mainly Heather and Bilberry but also include Bramble, Willow and Hawthorn – the latter three of which are found around the NNR base at Bank Island.

After our first catch, the following day we were amazed to receive our first re-sighting – H6 was photographed by Pete Short at Blacktoft Sands RSPB reserve, further showing the links between the two reserves. When visiting the site please do let us know of any colour-ringed birds you see, or if you see any of our blue colour-ringed birds elsewhere – either by messaging us on here, via our Twitter account or by using the log books provided in the hides.

On the day that we ringed the chicks, we also received some exciting news...
