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.

10/07/26 - National Meadows Day

Early July saw a celebration of the Lower Derwent Valley National Nature Reserve and its incredible hay meadows as part of National Meadows Day – hosted at the iconic Aughton Church in the small hamlet of Aughton (at the edge of the River Derwent’s floodplain grasslands), with the event proving very popular with visitors attending from all over Yorkshire 🤩

Starting with an early morning guided bird walk with local birder Duncan Bye, those who had pre-booked were treated to recently fledged Curlew, hunting Red Kites, singing Skylarks and various warblers and buntings, and (thanks to the Friends of Aughton Church) then finished off with a very welcome breakfast 🍞đŸĨ“☕️

Throughout the day Natural England’s licenced team of bird ringers were also able to show some of the local birds to the assembled crowds, and share with them their life stories, be that of the residents or those with their annual migration journeys to Africa, along with knowledge about their weight, size and habits. The capture and ringing of a Treecreeper and Kingfisher were real highlights amongst a bird-filled day đŸĻđŸĻ‰đŸĻ†


Visitors were also able to find out about the local moth population by exploring the contents of a light trap that had been set the previous night which had attracted an array of species, whilst our team of volunteers also spent time locating birds and showing them to everyone through their powerful binoculars and telescopes. Several (and hugely popular) guided walks were also enjoyed in one of the Ings meadows, which are managed each year by hay cutting and grazing 🚜🐑🐄

It was fantastic to see this event so well attended and to create a real buzz around the village, but we couldn’t have managed to organise and run this day without the help of our fantastic team of volunteers, so a huge thank you must go to all involved on the day and to those who helped behind the scenes 👏

04/07/26 - Himalayan Balsam

It’s that time of year again when Himalayan Balsam is starting to takeover and start flowering, and whilst we know it’s good for our bee species, unfortunately it forms dense carpets which shade out native ground flora, and so creating a serious problem (reducing diversity of flowering plants) and therefore having an adverse knock-on effect for many species in the food chain đŸĻ‹đŸžđŸĒ˛đŸ•ˇ️🐟

Also, due to this species being shallow rooted it fails to bind the soil together, and after having excluded almost all of the other plants from being able to survive, the ground alongside riverbanks, ditch sides and elsewhere in the floodplain becomes at risk of eroding away. However, good news is that the seed produced by such vast stands is usually only viable for a couple of years, so if we can prevent it from flowering and seeding then it is possible to reduce its competitiveness and restore a more diverse native vegetation cover đŸĒģ

Our teams will be hard at work over the next few weeks hand pulling and strimming vast areas of balsam, as will many other people – residents, birders and groups have taken it upon themselves to pull it on their daily or weekly walks, and the Bubwith ‘balsam bashers’ have made huge progress clearing it from around the riverbanks and elsewhere in the Parish (after just one season the results are fantastic with balsam few and far between), and in its place patches of Marsh Woundwort and Figwort can be found. The Pocklington Canal Society are holding task days along the canal this summer, so there’s plenty of options if you’d like to lend a hand –  to join in or organise a group task in the LDV please contact Lucy.Murgatroyd@naturalengland.org.uk or for tasks along the Pocklington Canal please contact PCAS direct, or for Bubwith, please contact Louise Smith at the Jug & Bottle – or if you’d rather work solo, why not simply spend 10-15 mins clearing a patch when you’re out and about, and you’ll be amazed what a difference it can make! 😄

We wouldn’t be able to manage the balsam around the LDV without the extra help provided by our regular volunteers and corporate groups, so a huge thank you to our team (some pictured below) who were hard at work tackling it last summer before it went to seed đŸŒŋ

25/06/26 - Corncrake/Aviva update

🤩 HUGE THANK YOU! 🤩

Over the last few weeks the response to the Friends of the Lower Derwent Valley’s new Corncrake Aviva fund has been incredible and quite simply has blown us away – the money donated is going to make a massive difference to the reintroduction project, making sure the sound of crex’ing Corncrakes from the Ings meadows is once again a common sound of summer. The money raised will also allow greater local community engagement and work with schools in producing a new children’s Corncrake book (following on from the success of our Whimbrel and Nightjar books) – so watch this space for more details 👀

 

It’s an exciting time to be part of the LDV team and the Friends of the Lower Derwent Valley, with the charity going from strength to strength each year thanks to your generosity. With another 15 days left of the project is there a chance we may reach £15,000 we wonder… here’s hoping! Raising this amount of money would be incredible – the more we raise the more we can deliver to make this reintroduction project a real success, and not just for Corncrakes, but for a whole host of species that thrive in the Ings meadows – if we get the management right for Corncrakes we will also be helping species such Curlew, Corn Buntings and Reed Buntings, not forgetting our population of harvest mice 😁


Please remember every donation made will be matched, with Aviva generously doubling each donation – if you haven't donated yet but would still like to, please use the link below – thank you 💰

12/06/26 - Responsible Recreation

Over the past week, our Responsible Recreation Team have been busy replacing some of our signs across the reserve with new information boards, detailing how we can all help protect wildlife during the ground-nesting bird season. This is one of the most crucial times of year for many of the reserve's bird species, and we're pleased to say that 2026 is shaping up to be an exciting year, with a short summary below of how the season has unfolded so far.

• A large number of Curlew clutches began to hatch from the 21st May, and recently our team recorded six pairs with 20 newly hatched or small young at one site – we now need to hope that these young chicks have the best chance to fledge and recruit into the breeding population. 

• An impressive 69 pairs of drumming Snipe have been recorded across the reserve so far this spring.

• Several Quail have now been heard (following the first on the 6th May).

• The first-ever breeding Marsh Harriers for the site have been recorded this year.

• Several broods of Lapwing chicks have already hatched.

• It’s been a strong spring for Common Cranes – a species which could potentially colonise the site in the future.



Whilst we would like our visitors to enjoy the reserve and all the wonderful wildlife it has to offer, we ask everyone to help give these vulnerable species the best chance of success by following a few simple guidelines:

Keep dogs on leads 🐕

Stay on marked footpaths đŸšļ 

Use designated viewing areas 🔭 

Take notice of signs đŸĒ§

Ground-nesting birds are particularly sensitive to disturbance, and unfortunately even well-intentioned visitors can inadvertently cause birds to leave their nests, thus exposing eggs or young chicks to predators. By keeping to designated routes, a safe environment can be created where wildlife can thrive.

You may notice livestock grazing in some areas across the reserve – grazing animals play an important role in maintaining the special habitats found across the Lower Derwent Valley, helping to create the varied conditions that species such as Curlew, Lapwing and Snipe depend upon. 

Many ground-nesting birds have evolved alongside grazing animals and are generally well adapted to their presence, and the movements of livestock are often predictable, allowing birds and grazing animals to share these habitats successfully. This is why conservation grazing remains an important part of the management of many of the UK's most important breeding sites for ground-nesting species.

Many thanks to everyone who is already helping us to look after this special landscape – together, we can ensure the reserve remains a haven for wildlife, while continuing to be a wonderful place for people to enjoy nature responsibly.

08/06/26 - Common Terns

In 2017, thanks to your support (via cards, calendars and log sales) and a kind private donation to the Friends of the LDV, four terns rafts were purchased by the charity, and since then, we’ve had the pleasure of having Common Terns breeding annually on the reserve (at least one or sometimes two pairs each year) - most notably on the rafts on the pool at Wheldrake Ings. 

Common Tern brood - Wheldrake raft - 2019

A total of 32 chicks have been hatched, ringed and fledged since that time, and so it was really pleasing to receive news about two of them this week.  

One of the chicks (ringed in July 2019) was seen at Tophill Low, whilst the other (ringed in 2023) was reported amongst the tern colony at North Cave Wetlands. In other years, we have had individuals reported from colonies at RSPB Aire Valley and the Farne Islands. One or two have also been sighted at Seaforth Nature Reserve in Merseyside and another, ringed in July 2019 (and the sibling of the bird seen recently at Tophill Low), was even spotted at sea off the coast of the Gambia. It's amazing to think how our four tern rafts and small numbers of breeding pairs have added to the population, and with each chick marked with a darvic colour-ring, it has allowed these incredible journeys to be revealed.
