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 how we manage the NNR for both wildlife and people.

10/05/21 - Returning Common Terns

We're delighted to announce that the first pair of Common Terns have returned to the Lower Derwent Valley for another year – arriving during the last weekend in April. Common Terns used to be a regular spring passage migrant to the reserve with occasional, but unsuccessful breeding attempts, however, thanks to a generous private donation to the Friends of the Lower Derwent Valley in 2017, two tern rafts were provided which resulted in the first successful breeding attempt for the site, with a single pair raising two young. Since then, and with an additional two tern rafts being provided, a total of 15 young have been reared and ringed on the reserve. 

From these colour-ringed birds we have had two subsequent re-sightings – a bird returning in its first summer to Lancashire, with the other seen during its first winter off the coast of The Gambia, Western Africa (pictured below) - amazing to think these birds cover such huge distances during the year and return every spring back to the rafts in the Lower Derwent – fingers crossed for another successful year.
