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.

17/02/26 - Skipwith Common NNR

Whilst the Lower Derwent Valley is currently doing a fantastic job of being a floodplain, our amazing volunteers have been hard at work on the slightly drier ground of Skipwith Common NNR. Armed with bowsaws, loppers and plenty of enthusiasm, they’ve been busy cutting back young birch and pine saplings to keep the heathland areas open and thriving. This work is being undertaken to make sure the site is in favourable condition for some of the key species that can be found on the Common such as Woodlarks, Adders, Lizards, Marsh Gentians and Round-leaved Sundew, not forgetting the Nightjar, who flies all the way from Africa to spend the summer on the heath! 🌍đŸĻ

So far, we’ve worked our way through several hectares, and we couldn’t have achieved this without our ever-growing volunteer crew, as well as the brilliant staff from WSP/FPRC Ecology and the Natural England north-east team, who swapped their desks for fresh air and made a huge difference with us at the end of last year đŸŒŗđŸŒ˛

Since the turn of this year, our hardy crew of volunteers have continued this work, with only a little bit left to finish now before the breeding season commences next month, and our attentions turn back to the Lower Derwent Valley – when (hopefully) the floodwater will have receded, and we may be busy carrying out flood damage repairs đŸĒšđŸĒ“đŸĒ›

10/02/26 - Forge Valley Woods NNR

Over the last couple of months our team have been splitting their time between the Lower Derwent Valley and Forge Valley Woods NNR, where we’ve been teaming up with Raincliffe Woods Community Enterprise and Butterfly Conservation volunteers to help manage this special woodland đŸŒ˛đŸŒŗ

Our team, who are not shy of a challenge, have been hard at work (and in all weathers) clearing fallen trees from public rights of way and tackling storm-damaged trees so that the boardwalk can be replaced with a safer and better surface for visitors to enjoy, and whilst one section of the boardwalk does remain closed for now, the northern part of the reserve is still open, with the planned work expected to be completed by the summer 🌞😎đŸĨž

During this time we’ve also been busy working alongside the river, opening up glades and re-coppicing bankside trees to let more light in, which will lead to more spring flowers, and provide a much-needed boost for butterflies, moths and bees, and when the coppice regrows, it will then create perfect nesting spots for birds and hiding places for mammals like wood mice and field voles đŸĻ🐞đŸĻ‹đŸŒđŸ

More recently we've also been opening up the quarry faces for their geological interest and valuable invertebrate habitat, and strimming the calcareous grassland pockets which will hopefully help species like rock rose flourish. A full litter-pick has also been carried out at both quarries and along the roadside, making the site nicer and safer for wildlife and visitors alike - nice to also see spurge laurel and wild garlic, and the first snowdrops of the year đŸŒŋ☘️ 🌷đŸĒģđŸŒē

Huge thank you as always to our fantastic team for their efforts recently, without whom, we simply would not be able to achieve even a fraction of our work load.

07/02/26 - White-fronted Geese arrival

This winter, especially over the last few days, there has been a considerable arrival of White-fronted Geese into the UK, including the Lower Derwent Valley – the first 20 were found on the reserve on Thursday, with numbers then increasing to around 400 on Friday and further to between 500-600 on Saturday. The arrival of these birds is likely to be due to a cold-weather movement, with them jumping across the North Sea from the Netherlands and Low Countries to escape the harsh weather. 

White-fronted Geese are most easily distinguished from other geese by the white flash on their forehead and around the bill, dark stripes on their belly and orange legs. These ‘pink-billed’ birds belong to the ‘Russian’ breeding population in tundra regions, and with Britain being on the western most fringe of their wintering range, numbers can vary greatly depending on how bad the winter weather is in any given year. 

Numbers wintering in the UK have averaged 2,000 in recent years (well short of the numbers present in previous decades) due to many birds now ‘short-stopping’ as climate change makes wintering in mainland Europe more attractive. The new ‘Birds of the LDV’ book reveals a similar scale of influx in February 1993 when numbers finally reached 830 later in the month (presently the record count for the site). Whilst visiting the reserve please do let us know if you come across any, and if you'd like to find out more about the species that visit the NNRs, there's still time to pre-order yourself a copy of our new book, just send an email to Lucy.Murgatroyd@naturalengland.org.uk

18/01/26 - Volunteer support

Last year was another record-breaking year for our incredible volunteer team, who gave up their time to deliver a stunning 918 volunteer days between them, helping us manage the NNRs – everything from clearing scrub, planting hedgerows, repairing hides and footpaths, building Corncrake pens, recording moths and ringing birds, clearing Marsh Ragwort and Himalayan Balsam, planting reeds, litter picking, seed harvesting, hay making and delivering logs - to name just a few 😄

We were also delighted to host another 40 corporate volunteering groups last year, from organisations such as Amey, the Army, Aviva, Britcon, Defra, Drax, the Environment Agency, HSE, Hull University, Lloyds Bank, Natural England, Nestle, Network Rail, Office of Rail and Road, Rural Payments Agency, WSP ecologists and York University – delivering a further 619 volunteering days (and helping pairs of hands) 👏👏👏👏👏👏👏👏👏👏👏👏

Between our regular weekly volunteers and corporate groups, this totals an additional volunteer resource of 1,537 days, and is worth well in excess of £120,000 of additional work undertaken on the NNRs and is hugely appreciated by us, the wildlife and the visitors that come to enjoy the reserves đŸĻ†đŸĻ…đŸĻ‰đŸĻ‹đŸžđŸđŸĻŽđŸĒļ🍄đŸĒģ

So, a huge huge thank you to all those that chose to undertake their companies volunteering allowance with us last year, and those that were happy to spend some of their retirement or little free time that they get in between shifts with us – we cannot thank you enough, and simply would not be able to achieve everything that we manage to without you all - we're incredibly fortunate to have such an amazing group of people who give up their time so freely 🙏 

If any of the work mentioned above appeals and you’re interested in joining our team and fancy helping to manage your local National Nature Reserves, please contact Lucy.Murgatroyd@naturalengland.org.uk for more details about how you can get involved  🛠️đŸĒ›đŸ§šđŸĒĩđŸŒŗđŸŒŋđŸĻđŸĻ‹đŸŒŋ

12/01/26 - Ringing summary

As last year came to a close, our team were busy submitting all of the records gathered on the reserve throughout the year to the various data record centres, county recorders and organisations that we work with. This included our moth data, Wetland Bird Survey (WeBS) counts, Rare Breeding Bird Panel (RBBP) submission, BTO heronry census and more. 

We have also finished compiling our end of year ringing data which saw over 5,000 birds ringed in the area during 2025. The top three amongst the 91 species ringed during the year were Swallow (810), Lesser Redpoll (710) and Chiffchaff (626) – although it was our work on waders that proved particularly successful. Of the 19 Black-tailed Godwits ringed (a species rapidly increasing on the reserve), 15 were seen again and reported at sites across the UK as well as in Iceland, whilst a motus-tagged Jack Snipe was the first BTO-ringed bird of its kind reported in Germany on spring passage, and we got a better understanding of Woodcock movements around the site day and night from using GPS tags. One of our Corncrakes made it to Spain, and a Willow Warbler to Morocco was a first for us. 


It’s also been really rewarding to be able to train a few new ringers along the way, as well as hosting various ringing displays and publishing some of the data collected in our new book ‘The Birds of the Lower Derwent Valley’. A huge thank you must go to everyone who has helped to collect all of this data, along with all of the people who have supported our work throughout the year, including those doing the hard work day and night, and those that have kindly granted permission to use their land – it takes a massive team effort to make the Lower Derwent Valley what it is – a truly remarkable place to live, work and enjoy – thanks to all. 

If you're yet to order yourself or someone you know a copy of our new book ‘The Birds of the Lower Derwent Valley’ - please send an e-mail to Lucy.Murgatroyd@naturalengland.org.uk
