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.

22/09/12 - Jack...frost

Last night saw the first frost of the autumn, on the equinox in the Lower Derwent Valley NNR and the same night saw the first Jack Snipe of the autumn appear and find its way into our mist nets.

Large numbers pass through the Lower Derwent Valley/Skipwith Common NNR's each year, mainly in October and November with a smaller return passage in March and April. Last nights bird seemed a little early but on checking the records it is probably about on time. Small, but sometimes significant numbers can occur in late September, with 24 caught in five mist netting sessions at Bank Island between late September and early October in 2002, when as many as 50-60 birds may have been present. However, most birds do occur from mid October to late November depending on water levels and ground conditions, the 14 caught drag netting over a 6 day period in November 2010 being typical of this.

This is the second bird to be caught here this year, following one caught on Skipwith Common earlier in the year. Hopefully we'll be in for another bumper year to add to our total of 83 ringed in the valley as the conditions look perfect for them and there is currently large numbers of Snipe still coming through. We have in the past held public Jack Snipe events if birds are reliable (similar to the public Storm Petrel ringing sessions on the coast) and these have always proved popular, so we would be looking to hold these again if it's a good autumn - more details to come later.

As well as the Jack Snipe, another 2 Common Snipe were caught and ringed along with 2 Teal.
