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.

10/05/12 - We think it's all over...it is now!

During the last week as a result of lots of hard work and help from local birders, we've had another fantastic number of colour-ringed Whimbrel spotted around their favoured fields in the Storwood area and elsewhere on the reserve. A total of 13 'new' birds for this year have been seen during the last seven days, including 11 birds still present that have been seen previously this year - some numerous times, inparticular Yellow/Yellow-Orange! This bird has been with us since April 20th, the average stay for a Whimbrel in the valley is just 8 days, however this one remained in the area for 14 days (we think) as it was last seen on May 3rd.

What has also been noticeable towards the end of the roost period is that some of the new arrivals have been the birds that were caught in the last catches of 2010 and so it fits with them arriving back now in subsequent years. Indeed it appears that 'early' birds arrive back early each year and those caught or present later in the spring also come back later each year (see previous post on just how arrival dates are so specific).

We've now also had two birds sighted that were originally ringed seven years ago during 2005, when the project was only in its second year. How far it's come since then, with over 100 birds now colour-ringed, and with 30 of those sighted during the last three weeks. It's been a great effort this year which has furthered our understanding of staging Whimbrel in the UK.

Thanks to everyone who has worked alongside us to make this project happen this year and over the course of the last 8 years - those that have helped catch and ring the birds, those that have monitored the roost site to obtain counts and identify where to put the nets, those that have read colour-rings and tracked birds in the field and all our partners who have had a role in making it happen in one way or another alongside Natural England - Yorkshire Wildlife Trust, Carstairs Countryside Trust, BTO and the RSPB. Only the last handful of birds remain now and many of the birds listed here will already be in Iceland or northern Scandinavia. We're already looking forward to them coming back next year - but hopefully we'll get some re-sightings away from the valley this year aswell.
