Puffins- the spell of the Northern Monks.

The little tourist boat out of Ulver Ferry on the Isle of Mull drew towards the towering cliffs of Lunga, largest and northernmost of the Trennish Isles, the chain of rocky little basalt islands in the Inner Hebrides, north of the famous Fingal’s Cave on the isle of Staffa, that great monument to undersea volcanism and geological forces. The water we crossed was crystal clear, and rich in life, fish weaving between fronds of waving kelp beneath the surface, moon jellies, and occasionally more unusual cnidaria, drifting everywhere. At one point even Common Dolphins were leaping beside us.  We docked at a rocky promontory on the island and made our way ashore on the columnar basalt, climbing a short cliff path. The skipper had warned us the birds would hypnotise us, that we’d risk falling into a trance on the cliff path, and would have to come back to the boat without seeing the spectacular heart of the seabird city which lines the steepest cliffs. His warning was spot on, but not heeded.




We sat up on the cliff top, among the wild flowers, the Bird’s foot trefoil and Burnett moths, on the rabbit-grazed, short grass, and watched the comings and goings of the Atlantic Puffins (Fratercula arctica) for hours. Birds flew in off the clear blue water, on wings beating rapidly, with thick, vivid coloured beaks full of silver sandeels.  Adults with food swiftly disappeared into their burrows, even Puffins are not averse to nicking their neighbours’ food, and to the gulls and skuas a Puffin with food on land is an obvious target.  So, they take their food underground hurridly, and unload it for the subterranean Puffling, the single, fluffy youngster waiting in the burrow.  Puffins without bills full of food seemed to enjoy a more leisurely lifestyle, taking some time to enjoy the sun and each other, pairs bill-rubbing and calling to each other, enjoying the bonds which hold them together, companionable, almost romantic. We were, naturally, enchanted by these entertaining little seabirds, and never made the journey across the little island to the spectacular Guillemots and Kittiwakes up on the towering sea stacks.




My paternal Grandma loved Puffins, and as such I must have drawn and painted hundreds of pictures of them, and bought puffin calendars and birthday cards for her every year. Images of them adorned her home.  They were here favourite bird, and as such have always held a special place in my heart. However I was in my mid-twenties by the time I saw one, on another chain of islands on the West coast, right down in the Scillies.  Puffins tend to live far from us, on rocky offshore islands, like the Scillies or the Trennish, or famously on Lundy, where the Bristol Channel meets the Atlantic.  They visit the coastline only briefly, setting up in April, and gone by the end of July. Their vanishing act is thorough and though wintering puffins were encountered at sea from time to time, it wasn’t fully understood until the advent of geotagging.  Once their Puffling has come waddling out under the sky for the first time, and taken to the sea, the parents remaining tie to land is severed. They shed the bright, temporary sheath which has grown around their bill, and darker feathers grow around the eye, masking the big, white face patches.  They loose the ability to fly during the Autumn moult, and spend the winter upon the ocean waves, living like the penguins of the Southern hemisphere, undertaking deep dives, wings adapted for ‘flying’ underwater. The black and white countershading Puffins, plus several related Auks share with Penguins are an example of convergent evolution, where similar evolutionary pressures lead to similar adaptations.  They retain the ability to fly only because of the need to avoid land predators, and only in the breeding season, to reach their cliff-top nesting sites, and they are at their most graceful underwater.  Then, come March or April, they return to their home island, and reunite with their lifelong partner, smartly attired once again. Some compare Puffins to clowns, given their colourful features and ‘eye makeup,’ and their scientific name compares them to monks, Fratercula arctica means ‘little Brother of the North.’ The name Puffin once applied to any burrow-nesting sea bird, hence the confusing scientific name of the Manx Shearwater, Puffinus puffinus.




Puffins are members of the Auk family, Alcidae, and are related to the Guillemot and Razorbill, as well as the extinct Great Auk. The family resemblance is apparent.  Unlike their relatives, puffins nest not on precarious ledges on the cliffs, but in burrows at the cliff-tops, usually taking advantage of those abandoned by rabbits, though they are capable of digging their own, and often do, take note of the sharp grey claws on their feet next time you are close to one.  A single egg is laid underground, in a chamber carved out for the purpose. The chick remains underground in relative safety, out of the reach of Herring Gulls and Raptors which occasionally prey on Guillemot and Razorbill chicks. Puffins also differ from their relatives in their winter habits. Razorbills and Guillemots can often be seen in winter, forming big rafts just offshore from their breeding colonies, remaining visible to birders onshore all year round, but Puffins are always absent from these agglomerations, preferring to spend the winter in the vast, open Atlantic, the Bay of Biscay and the North Sea, rich fishing grounds to which they have been tracked by modern telemetry techniques.




Puffins have a number of predators, with Gulls and Arctic Skuas all too keen to steal their hard won catch of Sandeels, which the young Puffling relies on almost exclusively, and Great Skuas, Great Black Back Gulls and birds of prey such as Peregrines, will occasionally prey on the adult Puffins. They are even, in some parts of their range, still hunted by man, though not in Britain.  Climate Change, and the loss of Sandeels as a result, and as a result of overfishing remain the biggest threats they face. They are confined to relatively few colonies around the North Atlantic, largely on islands off North America and North-Western Europe, and this reliance on a small number of sites led to the Atlantic Puffin’s listing as Vulnerable by the IUCN, and they are Red-Listed as Birds of Conservation Concern.




Yet at some of their colonies they are thriving, and one of those seems to be that of the Isle of Lunga. Rich, clear Atlantic seas offer them the food they need, and they are bothered little by the tourists who continue to visit their island breeding sites in considerable numbers. They are confiding and allow close approach, and photography. A few nest still at Bempton Cliffs in Yorkshire, alongside the Gannets and the occasional visiting Albatross, and though closed this year given the unfortunate impact of the ongoing HPAI epidemic, the Farne Islands still host a healthy population of these charming, entertaining little sea birds. Go and see them.

Snospurven! Snow Buntings, Plectrophenax nivialis, and all I know about them.

 At the lower station of the Cairn Gorm funicular railway, just above Loch Morlich, not far from Aviemore and part of Britain’s most noted Ski resort, there is a small, and usually astoundingly busy car park, surrounded by high end tat shops and various small, ski-related enterprises.  Emma and I visited the Cairngorms’ eponymous mountain in the hope of catching up with the confiding Ptarmigan for which the lower slopes are noted. The heavens had, the night before, dumped impressive volumes of snow on the towering landscape, and, though some paths up to the Slopes were already well trodden, the mountains, for miles, were coated in a thick, deep blanket of white, softening their ragged edges. Snow brings a curious sense of silence, and seemed to dampen the hubbub of excited skiers, and we looked down on a winter wonderland, snow hanging in the branches of the pine woods of Rothiemurchus, all the way down to the loch shore and beyond.

Snow Bunting, Cairn Gorm, March 2023



There were, despite this being apparently the only centre of human activity for miles here, special, and especially beautiful, birds here. A small band of Snow Buntings perched on the sloping roof of the ski centre. They fluttered down to pick about in the snow beside the green, angular, corrugated iron structure, flashing black and white wings. They allowed close approach, unafraid of the people around. Eventually a small crowd of photographers, armed with long lenses, gathered, and the Snow Buntings were keen and obliging models. Charming birds of high altitudes and the high arctic, last time I visited the flock, apparently a fairly regular fixture around the lower car park and the higher Ptarmigan restaurant during the winter months, had already melted away to their breeding sites high up in the crags. Flocking, and moving around these lower slopes, and being confiding, are winter behaviours. They nest high in the rocky landscapes, males singing atop deserted and windswept crags, where people very seldom tread. Arctic/alpine specialists, they breed right up into Arctic Norway, Arctic Russia, Iceland and Arctic Canada, places of icy extremes. When I visited Arctic Norway, in high summer, ‘Snospurven,’ a ‘common breeding bird,’ were nowhere to be seen.  Both sexes become whiter in summer, as they feed around the snow line, grabbing the insects which drift up on thermals, to find themselves dropped just above the snow line, an easy meal for the Snow Buntings to take back to their chicks.  During the last ice age they thrived across Europe. What impact climate change will have on such specialists as these remains to be seen.

Snow Buntings, Cairn Gorm, March 2023



Britain’s only breeding Snow Buntings are the few hundred pairs in the highlands, but in winter, more do appear in the country, and tend to choose a habitat which couldn’t be more different to the Cairngorms. They gather in small parties on stony ground, usually on shingle beaches, and are a regular fixture in some spots along the East coast. Here, their white-and-sandy winter plumage provides remarkable camouflage, blending readily with the Carstone and iron stained Hunstanton chalk pebbles of North Norfolk.  Here too they can be confiding, on a recent trip to Titchwell it was a joy to find these small and cheerful little birds scuttling around our feet. They can turn up as far South as Kent and Essex, but favour the North and East, making landfall at night as they cross the North Sea from Scandinavia and beyond, from places which make the North Norfolk winter seem mild.

When we returned from our fruitless trudge through the snow on Cairngorm, without having seen a Ptarmigan, and a pair of noisy, cronking Raven the only new species on our day list of two species, we found 30 or so Snow Buntings now gathered, and a small crowd of photographers admired them, from just a couple of metres away.  What a privilege to encounter such charming and special birds, at such close quarters.

High Fashion and Green Metal in an Essex Summer: The Lestidae Damselflies

 As it is (ed: Not long past) Christmas, and I have already written of a decidedly Christmassy species, I thought, in the dark of St Stephen’s Night, to revisit the insects with which I spent a privileged summer, through the coastal marshes of Essex. The Lestidae damselflies, or Emerald Damselflies, come in a range of shades from key lime pie green, to metallic fir tree tinsel green, some bearing a dusty blue pruinescence. They are desperately fashionable too, subject of many treatises, management plans and UK Wildlife Podcasts, in part because of their undoubted beauty, more subtle than that of the splendid Calopteryx spp - perhaps more of them later- and less easily spotted than the big Aeshnids I wrote about before. Essex is their spiritual home- and arguably one of the epicentres of their remarkable colonisation of these islands. All four breeding species are found in the county, and I had the privilege of meeting them all over the summer of 2022.


Scarce Emerald Damselfly nomming a Blue Tailed Damselfly (Ishnura elegans)



Willow Emerald Damselfy, RSPB Bowers' Marsh, Essex. 

My first encounter with these splendid creatures was a couple of years ago at RSPB Rainham Marshes, where I met a gorgeous, deep bronze green insect hanging serenely on some wetland tree that may or may not have been the one from which it took its common name. This slim and delicate creature was a Willow Emerald (Chalcolestes viridis) a stunning creature which immediately caught my eye, especially as it was October, when all but the hardiest Common Darters and Migrant Hawkers had reached the end of their season. The Willow Emerald is unique among British odonata as it does not lay its eggs in water, but instead, in neat incisions made in woody vegetation overhanging water with a modified ovipositor. I have witnessed them laying eggs like this while still in tandem, the male gripping the female with his anal claspers, protecting, or jealously guarding her. From these eggs the tiny prolarvae emerge in spring, and drop into the water below to continue their life cycle, much more typically. Any which fail to find water do not make it, but conversely, being to an extent free of the need for water during late summer oviposition offers an advantage in a drying climate.  This species was first recorded breeding in the UK in something like 2009, in Suffolk. On a September walk by the Thames at Tilbury in 2022, with my good friend Chris, we found hundreds of these beautiful, bronze green insects, hanging out on Brambles tens of metres from fresh water. It is a species which has undergone a meteoric rise. Look for an all-green Damselfly, sometimes shimmering bronze in the sunshine as the light catches its iridescence, with clear wings (mind those flashy Calopteryx!) white pterostigmas (the dots in the ‘outboard’ corners of the wings), hanging out on marginal woody vegetation near still or slow-moving water.

Willow Emerald, Tilbury, September 2022


A few years later, while walking among the ditches at an EWT nature reserve way off the beaten track yet not too far from Basildon. Hanging on a branch, apparently relatively freshly emerged, was a beautiful male Scarce Emerald (Lestes dryas). Contrary to its English name, this species seemed very numerous on the sites where it lived. A hulking brute of a damselfly, size being a key if not universally reliable way of separating it from the smaller Emerald Damselfly (Lestes sponsa), and another species identified as having a distinct upward population trend, it likes Sea Clubrush choked ditches, sometimes to the consternation of site managers irked by its insistence on enjoying exactly the habitats wading birds do not, and often co-occurs on the coastal grazing marshes also favoured by Small-Red Eyed Damselflies and Ruddy Darter Damselflies. Like all Odonata it is an active predator, adult and nymph, largely taking small flies,  but not averse to dining on its distant relatives. At RSPB Old Hall, what I initially took to be a mating pair of Blue-Tailed Damselflies, turned out on closer inspection to be a Scarce Emerald feasting on the corpse of a Blue-Tailed Damselfly. In addition to an impressive display of predation, though I had no way of telling whether the Emerald had caught its prey on the wing or simply made a fortuitously (for the Emerald) timed landing, it represented a good chance to compare the blue bits of the two species. The steel blue pruinescence, a dusting of scales which fades with age, contrasted strongly with the almost luminescent looking blue tail-light of the commoner species.  Scan through the big crowds of Blue Tailed Damselflies for this big beast, and use your close-focus bins or a good photo to identify it by the pruinescence covering the whole of the first two segments of the abdomen, and the big, bent-paddle claspers at the back end to separate from male Lestes sponsa. A slightly different pattern of green and pale cream on the thorax separates the females of these species.  Look for them in June and July, I saw few of them after the big heatwave of 2022, for reasons unknown, perhaps it baked off the adults or desiccated any late developing nymphs.

Historically, the commonest of the Lestidae in the British Isles, and still the one you’re most likely to encounter outside of South Eastern England, is Lestes sponsa, the Emerald Damselfly, you may hear it called the Common Emerald Damselfly.   This species has undergone something of a decline of late, like many of our odonata, as documented in the State of Britain’s Dragonflies report. It is hard to separate from L. dryas, I recommend a good book with the illustrations of Richard Lewington in it and a good pair of low-magnifying small binoculars for close focus, though any particularly small Lestes-with-blue-bits is likely to be one. Sadly I encountered just a few of this species during my summer transects.

Emerald Damselfly, Essex, 2022


The fourth species is the newest, and perhaps the slowest colonising, the beautiful and distinctive looking Southern Emerald Damselfly (Lestes barbarus). This is a gorgeous, key lime pie of an insect, with its dark green metallic upper surfaces contrasting with the pale, green-tinged yellow of its undersides, boasting a unique and instantly recognisable (yes, really) bicolour pterostigma, half milk white, half blackish brown. It has distinct ‘antehumeral stripes,’ look for markings like braces on its thorax. Its stronghold is on Canvey Island, of all places, I am advised a particular ditch is a good place to look, but I found it on the site near Basildon, where it was a new record. More delicate looking than the other three, it was first recorded in Britain in 2002, in Norfolk, and it’s been gradually colonising low-lying Essex since being discovered at Wat Tyler Country Park by Neil Phillips in July 2010, with other early records coming from Gunners Park, Shoeburyness in 2012. It is a more committed climate change rebel, and habitat specialist, than even the Willow Emerald, relying on ditches drying up in late summer for oviposition. I could scarce believe my eyes when I found one near Basildon on an EWT reserve. These species are moving so fast and unpredictably with their quiet invasion that they are one group in which the observations of keen eyed amateur naturalists and local surveyors can make real changes to known distribution maps.

So think of them on these winter days, and dream of them shimmering beneath a warm summer sky. Their season will roll around soon enough. Get yourself a good dragonfly book, a good pair of bins, and, come June, go to your favourite wetlands. You may just find yourself a new favourite insect there.

The Darter Dragonflies

As I write, it is grey outside. Mild now the now has melted, but drizzling and chill. Dragonfly season is well over. But it lasted into October, even November with the mild conditions and today feels an excellent day to look back.
Ruddy Darter, male, Essex 2022

At nearly every site I surveyed, the most numerous genus of Dragonfly I encountered, especially as the season pushed on into August and September, was Sympetrum. Specifically, Sympetrum sanguineum, the Ruddy Darter, and S. striolatum, the Common Darter, the former apparently capable of surviving even mildly brackish water conditions, favouring low lying coastal marshland, occurring alongside Scarce Emerald Damselfly (Lestes dryas) and Southern Migrant Hawker (Aeshna affinis). The latter, S. striolatum, is capable of flying well into the season of mists and mellow fruitfulness and is often one of the last dragonflies on the wing. However despite their abundance, and their abundant charisma, this genus seems relatively unexplored in the popular literature.

These represent the two commonest species of Sympetrum, a genus in the family Libellulidae. Both species are broadly speaking red in the adult male, and gold, fading to brown in the the females. These creatures are, like other Odonata, agile aerial predators as adults, darting from their perches and sunbathing spots to seize small insects off the wing. It is this darting habit which gives them their common name. Their larvae lurk in almost any still or slow-moving body of water you might find.
Common Darter, Rainham Marshes, October 2021


Most numerous in the low coastal marshes of Essex in June and July is the Ruddy Darter (Sympetrum sanguineum),the males vivid, blood-red as the scientific name implies, the females an eye catching straw gold. They are the smallest of the ‘large’ dragonflies (Anisoptera) typically on the wing. They tend to form an assemblage with Scarce Emerald Damselflies (Lestes dryas) and Southern Migrant Hawkers (Aeshna affinis) alongside several of the small, blue damselflies, a habit noted by Brooks and Cham in their excellent field guide, which I found reflected strongly when I had the privilege of carrying out dragonfly surveys for a conservation organisation in the Summer of 2022. The males possess something of a ‘waist’ to the abdomen and can appear club tailed. Legs are jet black and the thorax lacks distinct stripes.
Common Darter, Otmoor, Oxfordshire, September 2022

Common Darter Breeding territories are closely guarded, with adults prepared to chase away any intruders, but away from water, their habitats are different. They like to be in the sun, and pick the sunniest spot they can find, and bathe in it, absorbing the solar energy through their skin. Signage, gateposts and fencing are among their favoured perches, and here they can gather in large numbers, occasionally lifting up, briefly, to grab some passing prey on the wing, or in readiness to flee a threatening shadow, before settling back down again, usually in the same patch of sunshine from which they took off. In Autumn especially, Common Darters can be surprisingly willing to come and sit on an outstretched hand, something I have witnessed and done several times, at a few sites up and down the country. Try it one sunny afternoon. Go somewhere with abundant Common Darters, any still water with adjacent sunlit rides is a good bet, find a patch of sunshine, and hold out a hand.Perhaps these engaging insects will come and visit. Stand calmly; they are completely harmless and will not bite, and they will use you as a sunbathing and bug hunting post.
Black Darter, male, Garry, Isle of Lewis and Harris, Scotland, August 2021

Both Common and Ruddy Darter are abundant and thriving, but another Sympetrum, S. danae, the Black Darter, a specialist of acidic pools on heath and moorland, has shown significant declines in its numbers in recent years. It is still an abundant dragonfly in the somewhat specialised habitats in which it occurs. Our smallest Sympetrum, and indeed our smallest true Dragonfly, shorter than your little finger, the male S. danae is also the only entirely black dragonfly in Britain; the female is black and gold. Like their red lowland cousins they can be confiding and will occasionally perch on fingers. Another upland species, under more extreme threat of local extinction, is the White-Faced Darter (Leucorrhinia dubia), reintroduced since 2010 to Foulshaw Moss in Cumbria, a Cumbria Wildlife Trust reserve probably most famous for its breeding Ospreys. A true specialist, this beautiful insect, with a white frons and a body dappled red and black, or gold and black in the female, they spend their larval development right down among the mass of sphagnum, avoiding open water, or anywhere fish can be found. Like so many species of the North, it is threatened by peat extraction, the abandonment of traditional moorland management, and by a warming climate. The peatland habitats in which these two darters dwell represent an important carbon sink, ever growing Sphagnum, is a real asset in our fight against man-made climate change. Efforts to secure the future of these two little dragons in Britain are efforts to secure the future of our world and ourselves.
White Faced Darter, female, Foulshaw Moss, Cumbria, May 2015

So keep an eye, next summer and into the Autumn, for these species wherever you happen to wander. The two ‘red’ species so numerous here in Essex are common and widespread, flying from May into late October, even November. They are sometimes overlooked in favour of the more glamourous Aeshnids and distinctly fashionable Lestidae damselflies, but I think they have a remarkable charisma of their own.

Lydd Airport Expansion



Finding time to blog is sometimes a bit of a challenge.  This is why I am blogging about an announcement made now several weeks ago. On the 10th of April the news broke that permission had been granted for Lydd airport to be expanded, a measure which will may conclude the story of Dungeness’ National Nature Reserve’s “Death from a thousand cuts” to quote the expression once used by the botanist Brian Ferry, who has worked extensively on the site.


Dungeness Old Lighthouse from the RH&DR narrow-guage railway.



Dungeness, announced as “the other lands end” by a sign welcoming visitors to the expansive National Nature Reserve and ramshackle fishing community, is a totally unique habitat, with no parallel existing anywhere in the world. It consists of miles of shingle, bound by a community of lichen and bryophytes, grazed by a few hardy rabbits and hares.  It shows a complete succession from a maritime flora of rare Sea Kale, a curious, salt-tolerant member of the cabbage family, up to scrub, established on soils left behind by lichen and bryophyte pioneers, an example of life finding a way on a stony desert of rounded pebbles deposited by the sea. Wild flowers grow among the simpler plants and lichens, and in high summer these are visited by a range of butterflies, small tortoiseshell, small heath, small copper.  A single road winds across the foreshore, past the two lighthouses, historic and modern, past the Pilot Inn, serving local fish and chips, past the old coastguard cottages housing the Dungeness Bird Observatory, my home for five weeks in the Autumn of 2010, toward the dual towering, steam emitting monstrosities of Dungeness A and B nuclear power stations. A small footpath cuts north in a straight line across the shingle, past a memorial two a couple of brave Polish lads who died in their Spitfires defending the English coast, a threadbare polish flag flying over the wild, flat shingle country. A series of lakes,  traces of the gravel extraction workings which dot Romney Marsh are attended by herons, and in Autumn, swallows and martins gather over them in their thousands, surround an old cart track, where the lichen flora is barer, and where one can experience jelly legs after hours spent walking over the unstable shingle, which leads up to the famous RSPB reserve, home to the most obliging birds of prey in the country, a population of Marsh Harriers, a bird described by the lands custodians as rarer than a Golden Eagle. Yellow wagtails and meadow pipits breed here, and the reserve hosts black redstarts, specialists in these extreme habitats, and a rare colony of Tree Sparrows.  The gravel workings present an opportunity for migratory birds passing through the area from Great Britain, Ireland, Scandinavia, and even Iceland and Greenland, through the migration bottleneck the peninsula presents, on their way to the Mediterranean and beyond. From the lighthouse the ridges and troughs, landforms typical of an apposition beach, can still be seen, creating interest for Geomorphologists as well as Ecologists.

Lydd airport as it is now is fairly inoffensive. Light aircraft fly out of it, pleasure flights take in the beauty of the channel coast and the Kent countryside. But the news of impending airport improvements threaten all of this, and, wooed by the promise of a meagre 200 new jobs (according to the Guardian’s transport columnist) local opinion is spilt, although a poll suggested 2/3 people would still rather not see their treasured NNR disappear, and are opposed to the airport expansion.  More concerningly, the scheme has been approved by government who claim, despite all the scientific evidence to the contrary,  that the airport scheme will not damage local wildlife.  This is a clear falsehood, as the RSPB, and Professor Ferry, of whose teaching I had the honour when I was an undergraduate at the University of London, would testify. The Sulphur dioxide pollution associated with jet propulsion causes increased nitrogen deposition to the soil, to which lichens, complex symbioses of algae and fungi, specialists in nutrient-poor environments, in which the two organisms depend on each other to survive, are particularly vulnerable.  The increased nutrient levels will destroy the unique plant communities and the succession.  The RSPB manages its reserve for birds, and flight safety legislation may prevent them from managing in such a way as to encourage them. The Wildlife and Countryside act protecting wild birds from hunting does not apply where there are flight safety issues, and any birds perceived as presenting a danger to flights will probably be shot.  Lydd Airport expansion, for Dungeness and its wildlife, means death.  The RSPB has been campaigning hard against airport expansion, with petition after petition, and even calling in the initial approval of the scheme to judicial review.  Their case was that the nature conservation value of the area was overlooked by the planners, which is clearly true. Nevertheless the judiciary sided with the business cartel.  The airport is owned by the charming Sheikh Fahad el Athel, who was once in court over millions of pounds of commissions involved in weapons deals between BAe and his native Saudi Arabia, who complains the runway.

Cricket among the shingle at Dungeness.

The government seems intent to force upon us some new airport building in the near future, despite widespread campaigns to the contrary. They support their war on Ecology through the use of academic stooges such as the Ecosystems Markets Task Force, a group, tellingly composed of economists, who claim it is possible to offset damage caused by commercial building projects simply by directing conservation effort, funded by developers, to other sites, equivalent to licensing an individual to destroy the Mona Lisa and replace it with a picture of a smiley face. Dungeness is irreplaceable, as the barren shingle “habitat creation” projects at Sussex Wildlife Trust’s Rye Harbour reserve demonstrates. Such habitats, and the landforms which accompany them, cannot be created artificially. This deserves another blog, but ridiculous exercises in market-based approaches will sound the death knell of the British conservation movement if they are permitted to get any further. Nevertheless they will try and fall back on such guidance notes.  Meanwhile Hundreds of loyal, Tory-voting West Londoners have succeeded in convincing the government not to expand Heathrow, with the help of well meaning green campaigners. Few of us see the need for increased airport capacity, and much as I love aeroplanes, and the opportunities for travel they provide, I acknowledge we need to reduce, not increase our capacity if we are to reduce carbon dioxide emissions and minimise the coming climate disaster. Campaigners, including those at the climate camp in 2005 I had the honour of attending, have done well, but using Heathrow as a focal point for protest is problematic, as it risks diverting development to places they can do much more damage, places like the Thames Estuary, and Cliffe. Places like Lydd.  The truth seems to be, although many West Londoners appear curiously reluctant to adjust to the jet noise which has been going on above their heads, usually since before they were born, Heathrow may just be the least worst place for this environmental tragedy to play out. Not Dungeness. We would all rather it didn’t happen anywhere, but so called green campaigners who talk of airports “in unpopulated areas” are really doing biodiversity no favours at all.
View across Dungeness to the Nuclear Power Station.

Now it seems the campaign against the airport, and to save Dungeness, could have found a pair of very unlikely friends. When it is next in court, as the RSPB will, with widespread support, ensure it will be, the main focus may be in the area of Nuclear safety.  Large aeroplanes and nuclear power stations present a fairly obvious safety risk and security challenge, and, especially in these days of paranoia, the risk of aeroplane-reactor collision, and all the associated fallout, are a real concern.  A blight on the beautiful landscape may yet, ironically, save it.  If not, one can hope that the legal fees will eventually build up sufficiently that the business interests whose endless greed would see this green, windswept paradise of bird life and lichen erased forever, will be put off by the mounting cost. The possibility remains that the cost of building the airport at Lydd will eventually prove prohibitive. We must not be complacent, campaigns continue to prevent it. It is not over, and it may yet go to court in Europe, where, as a designated SPA site, UK equivalent of the Natura 2000 network, the planning authorities will have to demonstrate that the airport, is in the vital national interest.

What is in the vital national interest is preserving this unique, and incredibly fragile and vulnerable wildlife habitat.

The Last Flurries of Winter



ese past couple of days, still in Lancaster and without any pressing deadlines (how wonderful it feels to be free of pressing deadlines,) I was rather hopeful of getting some good wildlife spotting in. It’d been nearly a week since I last went birding, when incidentally I was able to add Bittern to my Lancashire list, one flying through the evening sunshine over the still brown reed beds at the RSPB’s stunning Leighton Moss.  I was enthusiastic to get out there and find some wildlife, see something I’d not seen before, perhaps.  On my way to drop off my essay, it did occur to me there may have been a fall of migrants, with what I am  I handed in my essay on Friday afternoon, and, no sooner had I done so, than the wind began to pick up, and Lancaster was, not for the first time that day, raked by horizontal, and some might say unseasonal snow.

Unseasonal. With Pheasant tracks.

I cursed climate change for its increasing tendencies toward extremes of weather, and spent the day indoors watching films instead. When I did manage to face up to the unseasonably big freeze, I got in the car and headed up, away from the sea this time, and into the Forest of Bowland, an area of Outstanding Natural Beauty which lies to the East of Lancaster. It took only a few minutes on delightfully names roads (Bay Horse Road! Procter Moss Lane!) to reach the car park in Abbeystead, a small town in Bowland. I wandered into the woods toward Abbeystead Lake. Bird life seemed a little scarce, the woods were quiet, and the footprints in the snow, enchanting to look at though they were almost exclusively those of grey squirrels and pheasants.  However the great tits with their two syllable song, were really going for it, the harbingers of early spring appeared unperturbed by the snow, which was thick on the ground in places. There were a few blue and coal tits about in the branches, but bird life seemed sparse.

Upon reaching the lake, which was all pleasantly dramatic, lying in a steep-sided, wooded valley, with the snow white Bowland fells climbing up behind it, I startled up a few nervous mallards. Some teal, too, rested on the dark green water and a couple of Jackdaws passed overhead cawing. I continued round the lake, which was held by an impressive dam, and down into the woods. Robins and chaffinches occasionally flew across the path in front of me. As I walked back up toward the lake I became aware of a few Goosander, unfamiliar before my move up North but near ubiquitous round here it seems, floating about on the water surface, but I wondered where all the birds had gone. It occurred to me they may well have cleared out of these upland woods and headed somewhere at lower altitude, somewhere more sheltered, perhaps.  Walking across a bit of farmland on the way back to the car park revealed not just pheasants but also good numbers of Lapwing and Snipe in the fields, so the true upland waders at least were still on their spring habitat. Some of the lapwings were displaying, whooping and tumbling, using their broad wings to aerobatic advantage. Spring, it seemed, was in the air still somewhere, alongside the wind chill.  I drove home dodging pheasants and snowdrifts. One poor pheasant must have had the fright of his life, caught between a snowdrift, an oncoming vehicle and a Buzzard. Of course I waited until he had disappeared into the hedge beyond the snowdrift before I proceeded.

Today I headed down to a place near Scorton, on the river Wyre where it is still fast and narrow. I parked up at a picnic site with some bird feeders in it, which clearly hadn’t been filled for some time. A few blue and great tits hopped about in the trees above them, looking awkward and expectant. I walked past and onto the banks of the Wyre, where the tree canopy opened, The sky was blue, but a few flakes of snow fell from it inexplicably. A dipper shot up and down the river and paused on a rock for a moment, allowing me to take a (poor) photograph before returning to a cluster of branches by the waters edge. As it did so a second bird appeared and flew upstream. A pair of dippers, and a lovely new addition to my Lancashire list. These lovely birds are very scarce indeed down South, they are birds of the west and the midlands it seems, specialists of fast flowing streams, dipping under the water to hunt invertebrates and emerging still perfectly dry, smart and distinctive in their smart brown plumage and white breast.

Rounding the corner into the wood what struck me was the snowdrops. The wood was covered in them, and among them daffodils too were springing out of the ground. In stark contrast to the upland wood in Bowland, this wood down near the Wyre was a different matter. The snow had all cleared, as if it had never been there (of course, it might never have been there) and the snowdrops and daffodils still stood proud. March snowfall has been part of these plants evolution, of course. When the channel first separated Britain from the continent, about 12 thousand years ago,  isolating its impoverished fauna, anything which could not tolerate March snow would not have been able to survive. Colder winters abound through our history, the mini ice age of the 18th century, the cold snap of the 1970s, and spring flowers have made it through. Here they formed a glorious white carpet splashed with yellow. Somewhere among the singing great tits I thought I heard a chiffchaff.  Cormorants flew overhead through a blue sky, and a buzzard was patrolling somewhere. Spring wasn’t cancelled, it had just had a minor setback, and it will be interesting to see what effect this late flurry of winter has had on wildlife phenology as the year progresses.
