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.

10/06/19 - Sand Martin success

Recently, we posted that due to the help and support over the last few years via logs, cards, calendars and donations, the Friends of the Lower Derwent Valley had been able to purchase and install two Sand Martin nesting banks at Wheldrake Ings and Bank Island. Once installation by John and his team from Green Future Building, our hard-working team of volunteers carefully filled all the nesting chambers and tunnels with sand - so that the Sand Martins could then move in and dig it all back out. We’re delighted to say it’s been an instant success, within days several individuals were busy excavating the holes at Bank Island, providing great entertainment for visitors in the adjacent hide to watch. 

At present, up to 24 holes have been excavated, and last week we were thrilled to find the first pairs are already incubating clutches, with others busy lining their nests. Several birds have also started to investigate the Wheldrake bank, hopefully visitors to the pool over the summer will be able to enjoy the comings and goings as the colony increases. 

This really has been a case of ‘build it and they will come’ – and in this case in just a couple of weeks. Many thanks to the Friends for their ongoing support and great work in helping deliver improvements to the reserve and adjacent area, and to everyone who has supported their work and our hard-working volunteers. Following on from the immediate success this year, we are hoping to install two more banks next year, including in front of the Geoff Smith Hide at North Duffield Carrs, however a lot of funds need to be raised beforehand. If you would like to help contribute you can do so via our Go Fund Me page (https://www.gofundme.com/conserving-the-lower-derwent-valley) – thank you.
