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.

15/08/26 - Ellerton Churchyard

It’s that time of year when our team have once again been working hard to help Ellerton Church Preservation Trust undertake the annual hay cut of the churchyard, with the aim of improving the diversity of wildflowers and spreading the benefits of the Ings hay meadows outside of the boundary 🌿πŸͺ»

As another growing season is over, we are pleased to say that the management of the churchyard is working as intended, with increasing amounts of Yellow Rattle and Greater Burnet, as well as many other herbs and finer grasses, along with other typical ‘Ings’ species that are now found in increasing numbers amongst the headstones. Whilst in recent years the churchyard has been looking more welcoming and awash with colour during the summer months, it is also now more resilient in the drought compared with many other areas of mown/drought-stricken grasslands, and so it's worth a mention and reminder of how our churchyards and gardens are incredibly important in providing valuable habitat for the local wildlife if managed correctly 🚜

Each year after our team have cut the meadow, it is then turned before being dried and made into bales by Rosewood Farms – helping both biodiversity of the site and the local farming community in producing feed for livestock. If you haven’t yet visited this area of the Lower Derwent Valley it’s somewhere worth calling on your next visit – set right next to the Ings the church overlooks the winter floods and is rather a special place in the local landscape – complete with its breeding Barn Owls who also feature in a specially made stained-glass window within the church, which details some of the history and wildlife of the Ings πŸ¦‰πŸͺŸ

As always, it’s been yet another fantastic effort by our team, enabling the ongoing management of the churchyard and helping to make more places better for wildlife and people in our local area, and helping nature to recover and spill out from the core of the valley – huge thank you to our brilliant team for their efforts πŸ‘

08/08/26 - Clouded Yellow/HBHM records

We’ve enjoyed several sightings of two special visitors of late, with the Clouded Yellow butterfly and Humming-bird Hawk-moth making appearances across the reserve, including in our NNR Base Garden.

The Hummingbird Hawk-moth is a small, day-flying moth, and is a summer visitor to the UK, migrating from Southern Europe in variable numbers each year, and appearing to be on the increase as our climate changes. In some years it can be common and seen in gardens, hovering as its names suggests like a Hummingbird as it feeds on the nectar of honeysuckle, red valerian and other nectar-rich species. 


The Clouded Yellow is one of our migratory European butterflies and is a regular visitor to Britain and Ireland, and although some of these golden-yellow butterflies are seen every year, the species is famous for occasional mass immigrations and subsequent breeding, which are known as 'Clouded Yellow Years'. A few individuals have been reported across the county this year, with the warm weather undoubtedly accounting for the influx of this southern range species.

It's been 15 years since our NNR Base Garden was originally planted by our team, with the idea of making it a demonstration bee and butterfly garden – including nectar-rich plant species such as cowslips, purple loosestrife, scabious, foxgloves, lavender, buddleia and water mint. As we hoped it would, this garden has proved to be a hive of activity, producing high counts of butterflies, in particular whites on the lavender, along with Small Tortoiseshells, Red Admirals, Commas and Peacocks on the buddleia. A number of bee species have also taken a liking to the lavender, whilst hoverflies and moths have been numerous – why not try this yourself and make a home for pollinators in your own garden – let us know how you get on!

28/07/26 - Quail

The year of the Quail! 🀩

2026 is proving to be a bumper Quail year with the largest influx recorded since 2011 when 2,000 singing males were recorded across the country. The Lower Derwent Valley (with its extensive flower-filled traditionally managed hay meadows) is one of the countries Quail ‘hotspots’ and an impressive 74 calling males have been located so far this year. The first birds arrived in early May, with several further arrivals – the most recent being in early July and involving birds singing from their other favoured habitat – barley fields. 

Quail are rarely seen and are often given away by their distinctive ‘wet my lips’ call coming from areas of dense grass, herbs and surrounding arable (https://soundapproach.co.uk/common-quail/). They are a migratory species of gamebird, travelling as far south as Africa for the winter, then returning to the UK to breed from late spring, with later birds arriving through June and July which may have attempted breeding in southern Europe before having a second attempt here. Most years around 100-300 calling males are recorded throughout the UK, although national influxes can result in much larger numbers in the country, and such influxes are often mirrored in the Lower Derwent Valley. 

A staggering 91 singing males were present across the reserve in 1997, followed by 70 in 2000. More typically, 5-15 males are located each year, so 2026 is certainly up there as one of the best. Our team have taken this opportunity to ring a sample during the influx, and so far, have caught and ringed 18 individuals, which given only 220 have ever been ringed in the UK is a huge addition to the national totals, and will hopefully lead to more valuable data on the conservation needs of this incredible little gamebird. Please do let us know if you’ve heard any on your travels around the reserve, thank you.

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 🍞πŸ₯“☕️

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 πŸ¦πŸ¦‰πŸ¦†


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 πŸšœπŸ‘πŸ„

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 πŸ‘

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 πŸ¦‹πŸžπŸͺ²πŸ•·️🐟

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 πŸͺ»

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! πŸ˜„

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 🌿
