Birds of the Somerset
Levels and Moors

Bird populations are in constant change. In many cases this means decline. But two projects on the Somerset Levels and Moors focus on species whose numbers are increasing. Partly this is due to the restoration and creation of new habitat by the various wildlife organisations which work in partnership here; partly due to an ambitious reintroduction programme; and partly perhaps due to climate change, which has facilitated the spontaneous colonisation of a species new to this country.

The Great White Egret

A short film about the Great White Egret ringing programme has just
been released by the Somerset Wildlife Trust

We are all too well aware that the natural world is in crisis, and that many species are declining due to a combination of factors including habitat loss and climate change. But for some, our changing world presents new opportunities. Over the last decade the Great White Egret has begun to establish itself as a new breeding species in the UK. Once killed for their magnificent bridal feathers which were sought after for the decoration of ladies' hats (and so helping to inspire the foundation of the RSPB), the egret family declined in numbers across Europe during the nineteenth and early twentieth centuries. But fashions changed, protection measures were put in place, and the climate warmed. Fifty years ago we watched the Little Egret spread from its European stronghold into East Anglia and then gradually across England, and over the last twenty years it has been followed by its larger cousin the Great White Egret - which bred successfully for the first time here on the Somerset Levels in 2012.

At first sight the great white egret is just white. But the bird has many ways of making white into a statement. Breeding adults acquire vivid green skin around the base of their bills, which turn from yellow to black, and their legs change from brown to a deep and impressive red. Over its workaday plumage the bird grows a bridal gown of loose feathers which can be raised and lowered in display. Pairs build stick nests on rickety reed platforms, usually in colonies which here in Somerset can number up to 24 nests. They lay three or four blue eggs; sibling rivalry is intense, and typically two chicks survive. Once fledged, the young birds disperse widely, often congregating in winter roosts before settling down to breed in their third year.

Wanting to find out more about how best to welcome and safeguard these magnificent white herons, we have started a ringing study programme to see what we can find out about this new UK species. Over the last few years a team of volunteers have watched over the first nest sites, monitored the behaviour of the breeding birds, ringed some of the first chicks and kept records of their dispersal. This has involved drones, kayaks, and hours of patient observation. Birds now nest in colonies scattered across the Avalon Marshes, and their numbers are growing year on year: from an initial two nests in 2012, there were 53 successful nests in 2023, from which 88 birds fledged. Since 2016 we have colour ringed 45 of the nestlings, and most of these ringed birds have been resighted in locations across the country - from Dunbar in the north to the Isle of Wight in the south, and from the coast of Wales in the west to the coast of Suffolk in the east. At least two of the older birds have returned to breed here on the Avalon Marshes.

The colour ringing project is registered with the British Trust for Ornithology and the European colour ringing scheme, which can be accessed here. A paper 'Great White Egrets in England - tipping the balance' was published in British Birds in May 2022

In order to further our understanding of the habits and requirements of this species we are reliant on sightings of the ringed birds. So if you see any colour ringed great white egrets please do drop me an email at, and I will let you know when and where it was ringed, and where it's been seen since then.

The Common Crane

For the Common Crane, the story was, until recently, going in the other direction. Cranes are magnificent birds; 'medieval herons' as a fascinated onlooker said recently. Once common throughout the UK, scores of places up and down the country are named after their former population of cranes. But cranes are large, standing up to four feet tall, and roast well; we know that the Iron Age inhabitants of Glastonbury Lake Village ate them, and we know that in 1251 King Henry III hosted a Christmas feast at which 115 cranes were served. By the 17th century the crane was extinct in this country. But in the 1980s a small colony established itself in Norfolk, and by the early 2000s there were small numbers of breeding cranes in Yorkshire, Suffolk, Cambridgeshire and Aberdeenshire. Finally, 2010 saw the launch of an ambitious project to bring them back to the South West.

Over a five year period, 93 common cranes were hatched from eggs donated from Germany, reared at Slimbridge WWT and released onto the Somerset Levels. The programme was successful, and cranes now breed across the South West. I have been working as part of a small RSPB team to monitor and ring birds from the new generation of wild cranes. Birds are fitted with a radio tag and individually identifiable set of lightweight plastic rings, and released to join their parents. The Somerset population is now on course to become self sustaining, with birds breeding in an increasing number of locations. In 2021 a milestone was reached with the first fledging of a third-generation bird, reared by a bird ringed as a chick in 2016. About 15 young birds are now added to the population each year. Thanks to the reintroduction project, the number of UK cranes has doubled.

For centuries cranes were a conspicuous part of our landscape. Celebrated in poetry from the time of Homer onwards, they were included in many of the collections known in the Middle Ages as bestiaries - an early form of natural history enclopaedia which provided information about the species and stories illustrating how it lived and what we can learn from it. One of these was made in the 13th century here in SW England, and the British Library has put together a fascinating animation to tell the bird's story. Watch it by clicking the image below right, and see if you can spot the accurate bits!

Today we know that cranes live for up to 14 years; they find a mate through a carefully choreographed dancing display and usually (but not always!) pair for life. Their unique bugling call can be heard up to three miles away. In the winter they come together in flocks; in spring they split into pairs and establish distinct territories. They feed on unimproved grasslands and winter stubble, roost and nest in or near water, and lead their chicks out to forage in mature hay fields. They are, once again, becoming a familiar part of our rural landscape.


In 2021 we ringed three second generation birds, offspring of the original reintroduced group. One of these, nicknamed 'Sherry' after its parents Soar & Cherry, was reported from the Vendee region of France in October 2023. Instead of returning home to Somerset, Sherry paired up with a Scottish crane who swept it off to its own home territory of Aberdeenshire! The Somerset population is not migratory, although the native populations are - so this is all the more surprising.

A second bird, nicknamed 'Meg' after her parents Clegg & Michaela, has also found a partner and is currently nesting here on the Avalon Marshes. Cranes normally breed from the age of 5 or so - but we are hoping for the best for both Sherry and Meg!

Sherry made the BBC news here.

Why bother?

Why should we bother to look after the natural environment and the creatures with which we share it? For many reasons, not least that it's where we live, and we have been given responsibility to look after it. It's now recognised that our economic, physical, emotional and spiritual health is directly linked to our stewardship of the natural environment - a recent study concludes that the more bird species we see each day, the better our mental health will be.
