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.

13/02/12 - Breaking records

As of today we have ringed 203 ducks this month making it the best February to date after 174 in February 2004 (and we are only half way through the month). That’s 359 ducks during 2012, including exactly 220 Teal, which represents between 10-16% of the UK annual ringing totals over the last 5 years. It should hopefully generate a few recoveries in the years to come...

Although most of the effort has been focused upon wildfowl ringing, the net at the base feeding station has been open for a couple of hours during the last week in-between other jobs around the base. This accounted for 30 new birds with suggestions of an influx of un-ringed Robins, Dunnocks and Blackbirds mirroring other local sites. Three Reed Buntings were nice at this site whilst a Fieldfare was the first of the year to be caught. Up to 6 Short-Eared Owls were present in the southern half of the valley on Saturday (11th) whilst 2 Kingfishers are also still present on the River Derwent at North Duffield Carrs. 

Following on from Saturday it was a similar picture yesterday (but slightly warmer one) with 6 new Wigeon, 4 Teal, 2 Mallard and a Moorhen, whilst amongst the re-traps was another different Shelduck, originally ringed in the valley in June 2010.

Today (Monday 13th) once again delivered another huge catch - 46 birds in the trap with another 26 new: 20 Teal, 5 Wigeon and 1 Mallard, with re-traps including a Moorhen, Coot and Pintail - 6 species of wildfowl.


  1. Alright Guys,

    2 new Mute Swan on the main campus lake at the Uni today had red darvics on, presumably your birds again!

    Male- Y334
    Female- Y308


  2. Hi Tim,

    Thanks for these - unfortunately not ours this time. Any red darvics starting with a Y are from the Yorkshire Swan Rescue, with rings used as part of the Sorby Beck Ringing Group. Both have websites for reporting colour-ringed birds, cheers.
