Village Voices Nature Note: Time to Fly
I hardly left Suffolk during lockdown – well, why would you? But this May I finally ventured out as far as another lovely county, Dorset, to try and catch up with a local celebrity there. I went to Giant Hill above Cerne Abbas, where a huge naked male figure (very naked, very male) is inscribed into the chalk hillside. That area is now fenced off, I was told, because women had taken to sleeping within the outline of the mighty male member hoping thereby to get pregnant. But I was in any case more interested in the lower slopes, where one of Britain’s rarest butterflies, the Duke of Burgundy, might be performing its own mating rituals. The Duke was never common in Britain, but in the nineteenth century it could still be found in several ancient Suffolk woodlands, like those at Reydon, Bentley and Bradfield. The last confirmed Suffolk sighting was in 1973, since when nothing. It’s hanging on at Giant Hill, though, breeding in very small numbers on the scrubby grassland where its favourite foodplants, primroses and cowslips, flourish in glorious yellow profusion. The Dukes are tiny but very beautiful, just thumbnail size with orange-and-brown chequered wings. They are the only European representatives of the Metalmark family, so called because of the distinctive glittering spots on the underwings.
You have to be at just the right place and time to see a Duke of Burgundy nowadays. The time is a short window in mid-May, and this is one of the few places. You have to be in the right posture, too, which is on your hands and knees, peering around to catch sight of the male perched on a stem, from which it sallies forth in short bouncy flights, to drive other males off its little kingdom. Just think, you have the whole of southern Britain to choose from and you have to defend to the death your minute patch (maybe a parable coming on here). The weather wasn’t great. Butterflies need it to be at least 14° C to warm their bodies sufficiently to fly and it was a cool, blustery day, threatening rain. But the clouds parted briefly and there was a sudden pulse of warmth from the sun. Almost immediately butterflies appeared, as if from nowhere: peacocks, tortoiseshells, red admirals, small brown jobs like grizzled and dingy skippers, and at last … yes, a freshly minted Duke, clinging to a buttercup.
The vision lasted only a few minutes. The clouds closed in and the rain came. But as the great Indian poet, Rabindranath Tagore said, ‘The butterfly counts not in months but moments, and has time enough’.

Village Voices Nature Note: a Local Success Story
I see that the Minsmere bird reserve is celebrating its 75th anniversary this year. Congratulations! It’s a haven for all kinds of wildlife, of course – some 6,000 different species at the last count – but its long history has been especially associated with one particular bird, the avocet, surely one of our most charismatic national species. Avocets are quite unmistakable. They’re tall, graceful wading birds, a picture of elegance with that pied black-and-white plumage – both bold and delicate at the same time, like fine porcelain. They have unusual upturned bills, which they swish from side to side, sifting the saline pools for small crustaceans and invertebrates, and they have those lovely long legs in an extraordinary shade of pale blue. Even the name sounds attractive. It’s derived from the Italian and sounds so much more elegant, as you might expect from the Italians, than the old English names of scoop-bill, clinker, yelper and barker. Avocets are impossible to miss if you are near a colony, since they keep up a chorus of soft fluting calls should you approach too close. In fact, if they think their chicks are threatened they can become quite aggressive and the avocets turn into exocets, dive-bombing the intruder.
Even if you’ve never seen a real avocet you must have seen an image of one, since they have long been the official RSPB logo and appear everywhere on their badges, signs and products. This was a very shrewd commercial choice by the RSPB, since not only are the birds beautiful to look at but they are also the perfect symbol of a great conservation success story. Avocets disappeared from Britain as a breeding species in the nineteenth century, as a consequence of human persecution and wetland drainage, but they miraculously reappeared in 1947 just after the end of the war, ironically returning to a habitat of flooded farmland and marshland which had been deliberately created as part of our coastal defences. They found their own way back to the Suffolk coast at two places: Minsmere, which is now the premier RSPB reserve in the country, and Havergate Island in the Ore estuary, where they bred successfully under conditions of high security (the RSPB even had a secret code name for the place – Zebra Island’). Since then avocets have spread along the East Anglian coast in suitable habitats, but they still need our protection in the breeding season, especially from uncontrolled dogs on the local seawalls – we had a tragic incident at Shingle Street a few years back. Let’s help preserve our avocets as a happy symbol of national recovery and regeneration – the return of a native.

Village Voices Nature Note: Despite Everything, Spring!
The chiffchaff is just a tiny olive-green warbler, weighing no more than a 2p piece, but it’s always the first migrant to make the long journey back. I listen out for it eagerly every March and think of it surfing the green wave of spring that travels steadily north across Europe, bringing with it a new season of light, warmth and growth. Twenty years ago they would arrive here about 15 March and fifty years ago 31 March – that’s global warming for you, but the thrill has been the same each time.
This year is different in another way, though. It’s just as exciting to hear this herald of spring again, but it’s terribly poignant. The news from Ukraine is almost unbearable and other, human, migrants are streaming across Europe in despair. It will soon be the spring equinox, the moment in the year when night equals day and the forces of darkness and light are in equilibrium. That’s a perfect metaphor for this conjunction of destruction in the human world and rebirth and renewal in nature. I had the same feeling in March 2020 when the Covid pandemic first took a grip, right at the start of one of the best springs in living memory. The spring was unstoppable then and so it will be again this year, just as the tides will rise and fall every day, regardless of human disasters. And we can find hope, beauty and consolation in these natural rhythms, of which we are an integral part, if we respond to them fully. That’s not evading the bad news but counteracting it.
You can listen to the chiffchaff’s onomatopoeic song, if you just google chiffchaff song. Some old country names represent this as chip-chop, chit-chat, siff-siaff (Welsh) or tiuf-teuf (Irish); while the Dutch call it tjift-tjaf and the Germans zilp-zalp. Whatever the language, by the time you read this the chiffchaffs will have arrived all over Europe, with the promise of spring in their songs.
Village Voices Nature Note: a Herald, but of what?
The Herald Moth’s name may be meant to recall the flaring skirts of the medieval herald’s traditional costume, but its scientific name libatrix suggests dieval herald’s traditional costume, but its scientific name, suggests an alterna- an alternative explanation. Libatrix literally means meant ‘someone who pours a libation’, so maybe we are supposed to imagine the moth as a Roman priestess in her fine robes, pouring a libation to the gods or we could update that and think of it as someone raising a glass to greet the New Year with a rousing `Good Health’. Well, let’s hope so. My moth will emerge from hibernation in March or April, and what will our world be like then? Who knows? A month is a long time in a pandemic.
I’m uneasy. I think it was the exceptionally mild weather that made this Herald more active. Daffodils are already shooting up their green spears and may be flowering as you read this. I saw a bumblebee on the ivy the other day and birdwatchers have just spotted the first swallows of the year in Cornwall. We had the warmest ever New Year’s Day and people turned out in crowds to enjoy the unseasonable temperatures but we know this isn’t normal – or didn’t used to be. Some early stages of climate change may seem quite pleasant round here, but look round the world: tornados in the American mid-West, Typhoon Rai in the Philippines, record fires and snowfalls in Colorado, a heatwave in Bilbao. This is the ‘new normal’ and it’s coming our way. Expect the unexpected.
At COP 26 last November – remember that? – we were given some reasons to be hopeful. But have the promises already been forgotten? Can we still turn things round? Perhaps the wise advice is to think like pessimists and behave like optimists.
Village Voices Nature Note: Strange Combinations
Muntjacs are not a native species and they still look rather strange in an English landscape. The unusual name is a clue to their origins. It’s derived from a Dutch word, which in turn comes from the Sundanese, a language from Java in the Dutch East Indies. Muntjacs are animals of Asian rainforests and were first introduced into Britain in 1925 by the 11th Duke of Bedford for his wildlife park at Woburn. Inevitably, some escaped and they have now spread rapidly northwards, reaching as far as Scotland and even Northern Ireland (assisted passage, presumably).
This explains some of their unusual physical features, too. They are our smallest deer – about the size of a large dog – and have a most unusual profile, with the hindquarters higher than the front end, so that they always seem to be walking downhill. That’s an adaptation to enable them to move easily through the dense vegetation of the monsoon forests which are their natural home. It also explains their shyness – they are safe from predators in that dark tangle and communicate with each other more by sound than sight, hence their other common name of ‘barking deer’.
Sex again, I’m afraid.They breed all the year round and the females can conceive immediately after giving birth, so there’s always plenty to bark about. If you hear eerie barks and screams round here at night, it’s more likely to be muntjac than your neighbours.
Their other spooky adaptation is a set of long recurved fangs, very prominent in the males and quite disconcerting if you encounter one close up. Most deer have large antlers for mating displays, but those would just get caught up in undergrowth in the jungle. Moreover, the muntjac’s tusks are hinged and can be folded away when not needed for combat – so more like flick-knives than daggers. Neat!
It’s always a risk introducing a new species into an established habitat and muntjac do quite a bit of damage here browsing bushes and cropping such much-loved woodland flowers as bluebells and primroses.
But I gather from a game-keeper I know that their venison makes very good eating, so maybe that points to a solution?
Village Voices Nature Note: the Humbler Creation
All the great naturalists in history have praised worms. Aristotle called them the intestines of the soil, while Charles Darwin studied them for over 40 years and observed, It may be doubted whether there are any other animals which have played so important a part in the history of the world. My favourite worm quote, however, comes from the peerless Gilbert White, curate of a small village in Hampshire, whose Natural History of Selborne (1789) is said to be the fourth most published book in the English language (after the Bible, Shakespeare and John Bunyan). White is the spiritual father of all today’s nature diarists (including me) and Selborne is the record of his daily observations in his tiny parish, which he rarely ever left. Here he is extolling the worm and making a very modern point about the interconnectedness of all life:
The most insignificant insects and reptiles are of much more consequence, and have more influence in the economy of Nature, than the incurious are aware of; and are mighty in their effect... Earthworms, though in appearance a small and despicable link in the chain of nature, yet, if lost, would make a lamentable chasm. For, to say nothing of half the birds, and some quadrupeds, which are almost entirely supported by them, worms seem to be the great promoters of vegetation, which would proceed but lamely without them.
In some cultures we become part of this chain too by eating worms – the Maori traditionally regarded them as a great delicacy; and in most others we willingly submit to the reverse process on death ...
Village Voices Nature Note: A Local Exotic
Well, that was a very good description of what is certainly a charismatic bird, but not in this case an exotic one – it’s a common British resident, the green woodpecker. We naturally associate all our native woodpeckers with trees, as their name suggests, and they do indeed use their powerful dagger bills to excavate nest holes in tree-trunks, probe the bark for grubs and drum on hollow branches to advertise their presence both to rivals and potential mates. But the green woodpecker has also developed this further habit of using its formidable drilling equipment to dig into ant colonies in our lawns and lick up the inhabitants with their specially adapted tongues.
The artist Leonardo da Vinci, who observed everything with insatiable curiosity, was fascinated by woodpecker tongues – why were they so long, he asked, and how were they housed in the woodpecker’s head when they were retracted? The answer was later revealed by dissection and is illustrated in this little diagram of a skeleton: the tongue is literally wrapped around the brain and its elastic movements are controlled by specially adapted bony cartilages.
In spring, the male green woodpecker has a very distinctive territorial call, a descending peal of (usually seven) loud ‘laughing’ notes that gave the bird its old country name ‘yaffle’. Another folk name was ‘rain bird’. It was widely believed that the yaffle’s call presaged rain, which would bring out the insects on which the bird feeds. An easy prediction to make in Britain, perhaps, when it is always about to rain anyway, but quite false. Possibly it derived from an even older, more primitive belief in the woodpecker as the ‘thunder bird’, who summons up the rain with his resounding drum-roll and wears the red badge of lightning on his crest.
Anyway, no need to invoke foreign exotica with such wonders close to home.
