Tangier Island in the Chesapeake Bay

I wonder if anywhere tugs at the heart more than an island home for an islander. This whimsical thought came to me while cruising on the Bay for a return visit to Tangier Island, when I was reminded of a far and different island I call my own.

My island birth was accidental because an epidemic infection in a London hospital closed the birthing center where I was due to make an appearance. My mother had to take the 30-minute paddle-boat ride across the Solent to her family on the Isle of Wight for a home delivery. Having missed the chance of becoming a “Cockney,” an Island birth made me a “Caulkhead.”

Isle of Wight

Isle of Wight

Islanders have been called Caulkheads since the days of yore when they were hired to caulk sailing ships, although the word was corrupted to “Corkhead” by poor spellers who had to explain the nickname. To be a true Corkhead, it was said, you must be thrown off Ryde pier as a newborn baby to see if you floated.

The smaller and more isolated an island the richer its store of anecdotes and stories, and it often boasts a reputation for eccentricity. If you don’t know what I mean try watching Whisky Galore, based on Sir Compton MacKenzie’s droll novel about Scottish islanders who “rescue” a cargo of whisky from a sunken freighter during World War II.

To be a true islander you need a differentiated mindset. This is partly in defense against outsider prejudice, but mainly for the sake of pride in the strip of water that sets you apart from others and enables the evolution of particular customs, habits and, dare I say, peculiarities. Caulkheads used to look aloof to the mainland across the narrow strait at “Overlanders” (shortened to Overners), but that was when the Isle of Wight was still virginal, before it became a Victorian resort for celebrities and royalty and a popular retirement home which made it just “ordinary.” The Vectis National Party in the 1970s tried to turn back the clock, but the independence movement fizzled out otherwise I might now qualify for an Isle of Wight passport!

The English Channel has molded an island mentality for mainland Britons, but the Isle of Wight was cast off from the mother island after the Ice Age melt so we might expect Caulkheads to have a deeper sense of apartness. Maybe that’s why they gave a large majority to the Leave campaign in the Brexit referendum (62% of a 72% turnout voted to leave the European Union). Tangier men and women too take pride in their unique identity and history.

I searched the horizon for the first hour of the crossing until I saw a thin black line shimmering between sea and sky on the hot day. I was joyful at the sight of Tangier again. At its peak above the high tide mark it is barely shoulder high, and ever at risk of being swamped by hurricanes which requires the entire population of a few hundred souls to be evacuated. Most of its 740 acres is a marshland paradise for wading birds and ducks, and far too hazardous even for houses on stilts. Little more than 10% of the land surface is habitable, and even that is slowly sinking and shrinking.

As we entered the channel we passed private docks with piles of crabbing pots alongside a shed and a berth for a shallow motor boat. Apart from a short tourist season, the Tangier economy depends on the “watermen” who earn the island’s reputation as the soft-shell crab capital of the world. After the blue crabs are harvested they are moved into tanks of salty water to molt their shells, leaving a carcass of mostly edible meat which is a seasonal favorite in restaurants.

Another lover of islands, Truman Capote, wrote that they: “are like ships of permanent anchor. To set foot on one is like starting up a gangplank. One is seized by the same feeling of charmed suspension: It seems nothing unkind or vulgar can happen to you.” I understood as we stepped ashore towards a few greeters waiting for us. A lady waved us into her golf cart, not for the sport for there is no golf course on the island, but for a ten minute round trip at top speed past the 15 mph warning (radar controlled). The sole policeman on Tangier has light traffic duties, and apart from a couple of emergency vehicles automobiles are almost absent.

Tangier Island

Main Street

When I took a seat in the cart beside my brother and sister-law who were visiting from South-west England I asked them to watch for differences to mainland folk. The uniformity of ethnicity and class was the first thing that struck them, and the preponderance of full beards was next. The islanders also had an unfamiliar accent which I was advised before my first visit long ago would sound like old West Country English. But I never heard obsolete words from Shakespeare, and my sister-in-law who is a native of that corner of England declared the accent was quite different to modern Devonshire and Cornish. Since no spoken language is frozen in time I don’t expect to hear the same twang elsewhere. We had plenty of opportunities to listen because the islanders like to stop for conversation with strangers, which is a rare compliment seldom paid today except in the deepest countryside.

We paused to cast our eyes on a plaque of World War veterans. We also wandered around a tiny cemetery reading inscriptions on the heavy gravestones that anchor shallow coffins from floating away during floods. I think there were far more Crocketts, Pruitts and Parks recorded than all the other names combined. Many islanders are direct descendants of the original settlers who came from Cornwall in the 1670s. Considering island life, I am not surprised there has been so little admixture over the centuries, although it was hard to imagine the rigors of winter there because we had a bonny day.

We stopped behind a picket fence to gaze at the old Methodist church of unspoiled white clapboard and black shingles and look up at the pointy bell tower, which is one of the highest points on the island after the water tower. The smell of soap and polish greeted me inside as I stared at the Victorian glass windows and rows of dark pews with hymnals neatly laid out. When I see a church that well-cared for I imagine a large and devoted congregation, and that day I imagined many memorial services held there for men lost at sea.

The museum is one of the highlights of a trip to the island, but you should leave behind the definition of museums in NYC, DC and London. The Tangier museum is the most amateur and most authentic museum I ever knew. Its managers have lovingly curated artefacts donated by residents to tell the story of their home and people. It is a living museum in which the curators and elderly docents are among the exhibits if you stop to listen to their stories. There is old crabbing and fishing tackle laid out alongside marine hardware, duck decoys and rusted shotguns. The walls are covered with faded newspaper and magazine cuttings about local stories of triumph, hardship and rare celebrity visitors. A yellowing 1930s article reported the arrival of a boat resupplying the starving islanders after three months of isolation in the frozen Bay. We forgot the time and had to run for ice creams at store before the only boat of the day returned to Reedville.

Islands are laboratories where the culture and living of small, relatively isolated populations adapt to the peculiarities of the environment and the whims of a maritime climate. They are biological laboratories too, where natural selection molds genotypes over eons to create forms and behaviors that exist nowhere else.

Over a hundred species of lemurs are endemic in Madagascar, over 90% of terrestrial mammals in Luzon in the Philippines are not found anywhere else in the world, and New Zealand has been a haven of strange and flightless birds. In Galapagos, the finches are distinct from descendants of a common ancestor in mainland Ecuador, and more recently diverged between islands as beaks adapted to local bugs and berries.

On some islands, bodies evolved to become giants, like the moas and giant tortoises, or became dwarfs, like the extinct hobbits of Flores, Indonesia. But you don’t have to go to the tropics to see the reshaping of a species by island isolation. I spent a week studying voles on the then uninhabited island of Skomer, which is separated from the rest of Wales by only a few hundred yards across the Jack Strait. The Skomer vole is a larger and cuter edition of the common bank vole in the mainland, and tamer.

The voles sat in the palm of my hand blithely nibbling grain, but such trust is disastrous when a new predator arrives. Island life is sensitive to change and immigration. Many native birds are now extinct in New Zealand and Guam, while Galapagos tortoises compete with feral goats for food, and so on ….

Tangier islanders face more threats these days, and I found them more pessimistic about the future than on previous visits. Their admirable self-reliance has served them well, but they now face external threats to their way-of-life that are hard to resist. Caulkheads fared better after they came under the gentle assault of Outlander hegemony because they benefited from a blossoming tourist industry, but Tangier men and women have few, if any, compensations for the challenges they face. Water levels are rising, crabbing quotas are falling, and young people are leaving.

Never send to know for whom the bell tolls on the old church, it tolls for thee. In a world that looks more uniform, if more economically divided, where a store or hotel looks the same in Georgetown, Guwahati and Guangzhou, where occupations were defined by geography and culture is blurred by globalization, Tangier Island stands out as a survivor from a more colorful age. Go to there to savor the difference and spend your $$$. Enjoy it for what it is and don’t ask for the amenities you expect on the mainland. Adjust your spectacles so you can see that what seemed poor and dull is rich and precious.

Where the Bee Stings

Bee stings … an occupational hazard for beekeepers. The price paid for hosting hives and stealing their honey. I score about three hits per season, and they are generally deserved from carelessly zipping my beesuit. But honey bee stings don’t give the biggest punch: that dubious honor is held by the tarantula hawk and the bullet ant, each scoring 4 out of 4 on the Schmidt Sting Pain Index.

Beehive

Beeware

Dr. Justin Schmidt is a doughty entomologist at the University of Arizona (The Sting of the Wild). Over a career he has invited stings from every hymenopteran species he encountered. He gave a score of only 1 to some ants and small bees whose stings didn’t hurt much or for long. Most honeybee varieties scored 2, which I can report gets my attention. Red paper wasps and velvet ants were at 3. Few species reached the top of the range – a blinding pain that feels extreme/ excruciating/ electric – and yet the pain from a ¼” tarantula hawk sting is long over (if not forgotten) before a honeybee’s sting has started to fade. Why the difference? Why do some insect stings give crippling pain while others are as mild as pressing a pencil tip on the skin, and many fierce-looking bugs don’t or can’t sting? Nature presents many conundrums, but this isn’t one of them because stinging makes sense in biology.

The hawks lay their eggs inside tarantulas which are eaten alive after their larvae hatch. They rarely sting us unless we try really hard to annoy them, as Dr. Schmidt must have done to obtain “data”. Why should they shoot their big gun when we don’t normally threaten them? As solitary wasps they have no “home” to protect. The mud-dauber wasps are also solitary, often making a tubular nest of dried mud on the sidings of our home. Schmidt tried very hard to get them to sting him, and when one was sufficiently enraged it hardly hurt.

Honey bees and yellow jackets, on the other hand, are colony dwellers that store food during warm seasons to support them with their queen through the winter in readiness for a burst of foraging and reproduction in early spring. Their honeycomb must be defended at all costs, which they do aggressively whenever a beekeeper inspects his/ her hives. But honey bees rarely sting while they are feeding in a garden or meadow unless you trap them between your toes, etc.

During the hot Virginia summer large numbers of bees gather at the side of our pool to take water back to their hive for air-conditioning. I can impress visitors by nonchalantly wading through a buzzing cloud, trusting they won’t sting me clad only in swimming trunks. For the same reason that they are relatively docile away from their food store, a swarm of bees that is emigrating to create a new colony is quite passive, even though it may look terrifying. But there is a different explanation for the old trick of circus performers who dared to pour bees into their mouths – by carefully selecting drones they can’t be stung.

Queen bees possess a sting, but they leave hive defense to workers and reserve their swords for dispatching rival queens. There is another difference between them. Queens can sting repeatedly, whereas it is a death sentence for workers because their anatomy requires stings to be ejected with some of the viscera.

Human sensibilities might deem their sacrifice altruistic for defending the hive’s socialist society, but surely natural selection could have evolved a superior warrior bee that can sting and survive, just as many other species can and do? Perhaps the explanation is that death is required for the release of a special pheromone for attracting other bees to escalate attacking a threat. This pheromone is a mixture of volatile fatty acids said to smell like bananas, and beekeepers lightly smoke their hives to pacify bees by masking the scent. I can hardly blame them for being angry, and in a feminist poem Sylvia Plath sympathized with female workers whose bounty is stolen by (male) beekeepers:

Stings poem

One of the scariest encounters you might have on a hiking trail in the South-West is with a mountain lion, but I would rather take my chances with the big cat than with a swarm of Africanized bees (aka killer bees). They are spreading north in states from Texas to California. A young man died this summer after a bee attack, as have several dogs and even horses. Africanized bees can’t be outrun, wait for you to come up for air if you jump in a pool, and can’t be fought off except with fire. They don’t have a more painful sting but are more aggressive – much, much more aggressive.

The victim wasn’t reported to be allergic, but the thousand stings on his body exceeded the lethal dose for bee venom. The major active agent in venom is an acidic peptide, melittin, which has anti-inflammatory properties and is probably responsible for its long-supposed medicinal value in the Orient. So there may be virtue in it, even while we try to avoid stings or carry an EpiPen as a precaution.

There is an outsized fear of being stung that beekeepers have to shrug off. But, apart from the 30 minutes of pain, let’s put a perspective on the big risk – of dying from bee stings.

According to CDC statistics for human mortality from wild and domesticated animals for the fifteen years to 2014, 486 people died from dog attacks, 1,163 from other mammals (mostly cattle and horses), 9 from crocodilians, about 15 from black bears and only one from a mountain lion. But 921 people died after being stung by bees, wasps or hornets, although most of them are thought to have been allergic to the venom. This is not a huge risk compared to others we face, and it is one that I dare say beekeepers hardly think about, but if we could compare the total number of attacks from all these species, combining non-fatal and fatal ones, I am sure bee stings would soar above all. And what do all these figures reveal – that we put ourselves most at risk not from ferocious wild carnivores but from the creatures we choose to live with or steal from.

Playing Possum

Playing possum is something that Virginia opossums do, but so do some other animals—including humans. But because it can help animals to outsmart a threatening predator, can it save us from a terrorist shooter or a rapist or a grizzly attack? A few plucky people have credited their survival through mass shootings in America and Europe to acting dead.

When the Scottish explorer David Livingstone was attacked by an African lion he tumbled into a delirious, catatonic state that bore a resemblance to death. “(The lion) caught me by the shoulder as he sprang, and we both came to the ground together. Growling horribly close to my ear, [the lion] shook me as a terrier dog does a rat. The shock . . . caused a dreaminess, in which there was no sense of pain nor feeling of terror, though quite conscious of all that was happening.” He survived the ordeal, not because the big cat turned its nose up at Livingstone’s “dead meat,” but after a native teacher came to his rescue.Poem_possum

I was musing about this story after I rescued a toad from our pool. It was a spadefoot toad (Scaphiopus holbrookii), so-called because it has a black, horny spur on each hind leg for digging holes. We rarely see this species because it lives most of the year underground and only ventures out in warm, wet weather.

When I saw it floating with outstretched limbs I guessed it was alive, but after netting it and holding it in my palm it was curled up as if it was dead. Motionless and unresponsive, its eyes were half-closed and both pairs of limbs were gathered in a praying attitude (for a toad). It didn’t fool me, but the attempt might be beguiling to someone who wanted to eat it. So I set it down on a rock beside the frog pond and stood back to watch. Two minutes later an eye cracked open, then a limb extended tentatively, and next it had disappeared into the pond with a fruity “plop.”

I can’t find any reference to spadefoot toads playing dead (scientifically called thanatopsis/ thanatosis), although it has been observed in other amphibians and when I cast a wider search I found examples in a range of animals. Some, like the toad, simply look moribund when threatened, but the hog-nosed snake goes further by emitting a foul odor to repel predators from taking “old meat.” There are sharks, iguanas, fire-bellied toads, cichlid fish, and even spiders that play dead, although in the last case only among males courting a much larger female. Even rabbits will sometimes act this way, although this might surprise people who grew up on a diet of heroic stories about Hazel and Bigwig (Watership Down by Richard Adams). Orcas have no predators so when they are acting dead they hope to trick their prey.

Scaphiopus holbrookii

Back from the dead

It must have taken many generations for these behaviors in toads and other prey species to replace the more natural instinct to fight or run or hide. Evolution comes at a high price of mortality until the hunted have perfected their act for fooling the hunter. But what should people do? Apart from those who play dead as art noir, it’s probably not wise in real life, and the security services don’t recommend we try when in dire straits.

Crazy about Chelonians (Turtlemania)

As I exited our driveway there was a screech of brakes and I had to join a line of stationary cars on the highway. This is an accident black spot. But while waiting for the wail of sirens and flashing lights of emergency vehicles, the lead car in the opposite lane started moving forward. I rolled down my window as it passed and watched the driver curl a grin under his mustache. I wondered about the dark humor and what those ahead of me could see as we crept forward and rubbernecked to the roadside. Soon enough I too was smiling.

Something looking like an upturned brown soup bowl was padding slowly to the safety of the grassy verge. It was a yellow-back slider. Had the reptile been a snake instead of a turtle it would never stop traffic: some motorists would even swerve to guarantee it never completed the crossing. Perhaps it is the strange beauty and harmlessness of turtles that touches our kinder hearts, or maybe turtle dreams because they symbolize good things—fertility, wisdom and longevity.

Rhodin poem

There are twenty-four species of turtles inhabiting Virginia’s waterways and coastline—from the tiny Eastern Musk Turtle (2-4”) to the grotesque Snapping Turtle (18”) to the giant Leatherback Turtle (record carapace length 74”), but only one of them is a landlubber.

Eastern box turtle

When I first saw Terrence on our lawn I assumed he was a pet tortoise that had escaped from a neighbor’s yard, but I was wrong on both counts. He is an Eastern Box Turtle and a wild Virginian. Europeans differentiate turtles and tortoises according to whether they are aquatic or terrestrial, but they are all called turtles in America. I may have been mistaken on another account because I assumed Terrence was male, but I didn’t rudely turn his shell over to examine his plastron. Perhaps “he” is a Teresa.

Updike poem

Terrence seems to nonchalantly trust that his carapace will keep him safe, and only ducks inside for a minute when I hold him or rub his shell. A bony carapace has been a wonderful protector of his tribe for 200 million years, but not any longer since a new predator on wheels arrived on the block. We mourn highway casualties.

Terrence - a curious chelonian

Terrence – a curious chelonian

Perhaps it is their naivety, vulnerability and inoffensiveness that appeals to us, or that innocent head swiveling on its periscope at a dangerous world that makes even aggressive drivers slam on brakes to avoid making chelonian pie. There are few non-furry animals we love more than tortoises/ turtles, especially box turtles and colorful terrapins. Sometimes they benefit from our care, but often they suffer from it. Thousands are legally collected for the pet trade in South Carolina (plus others in Europe), but few thrive in captivity for long, and I regret owning another Terrence when I was a boy.

When I see box turtles I wonder if they will be lucky to outlive me. They have more lives than cats, and are the longest-living animals in the region. Potential centenarians.

You might expect that great longevity will help to preserve the species, but not so—perhaps even the opposite. I mused about the evolutionary trade-off between longevity and fertility in Cheating Time (Macmillan 1996), and a potted story goes like this—

A species living in a protected environment (like a hard shell) or less vulnerable to predation, disease and starvation by virtue of structure and habits is under less pressure to grow up quickly to make lots of babies for perpetuating its kind. It can evolve a strategy of making a greater investment in a robust body that lives longer and matures later, and it doesn’t need to be superfertile to ensure its genes will endure. Mayflies at the opposite end of the spectrum only live for 24 hours as adults, while turtles—well, now you know!

A stretched life plan has served turtles well in the past, and giant tortoises once flourished despite postponing reproduction until around 50 years old. But in the days of ocean exploration and long sea voyages under sail crews took them onboard for fresh meat, and colonists introduced egg-eating predators to their homelands. After decimation their populations have never recovered because their rate of replacement is plodding slow.

Turtle image on St. Helena 5p coin

Jonathan is a giant tortoise that was brought from the Seychelles to Saint Helena in the South Atlantic in 1882 and is probably the oldest living reptile. Since he was already mature at capture, he had probably hatched around the year that Charles Darwin sailed in the Beagle in 1831. He now earns celebrity status living in the grounds of the Governor with a personal vet because of the distinction of great age and the threat of extinction for his species.

Believing that box turtles also deserve a special honor, some people have nominated them as the state reptile of Virginia. But when it was put to the vote at the Virginia General Assembly in Richmond, the motion was defeated. A delegate who spoke against the motion declared that any animal that crawls back in its shell at the first approach of danger and yields cravenly to murderous wheels is too much of a coward to represent a state with a proud military history. But if a turtle had made a defense of its kind at the Assembly maybe it would have praised their peaceable nature as a high virtue, and surely the Mock Turtle in Alice would have agreed, for he declared, “we called him tortoise because he taught us.”

Down on the Clover Patch

Woe betide the feet that trespass on the hallowed lawns of Oxbridge colleges! But you already know if you have seen Jeremy Irons as a Trinity Fellow nonchalantly striding across the Great Court in The Man Who Knew Infinity (2016). College lawns, golf courses, bowling greens and 40 million acres of American gardens are groomed to degrees of perfection by proud owners and hired lawn companies. The result is a green desert with as much biodiversity as a cornfield, but that is the point of all the effort and expense.

A closely-cropped carpet is no place for bees and other pollinators, something we admire for its greenness and never for fruitfulness. But the original lawns of medieval Europe were never so barren, nor could they have been before chemical fertilizers and powered lawnmowers and aerators. They evolved from meadows in the moist climate that suited them.

When lawns were tended around English manor houses and castles they were mixtures of clover, lily-of-the-valley, wild strawberry, violets, daisies, chamomile, thyme and self-heal among tussocks of grass. All are native plants that grow vigorously without a gardener’s care because they are well-adapted to the environment. Their blossoms used to feed bees before the scythe in midsummer, and some of the broadleaf plants were harvested for herbal remedies. But apart from a few favored grasses, they are marked for elimination in the modern lawn, as the Weed-B-Gon packet advises: “Clover is a perennial weed …” (Scott’s Garden Supplies).

Dickinson poem

The difference between early and modern lawns is like comparing Jackson Pollock’s fractal tracings in his early paintings to the dull murals of Mark Rothko. Didn’t Pollock declare, “I am Nature?”

Few people want a lawn looking early English or like Pollock’s Blue Poles (1952), though most of us admire a wild flower meadow. Perhaps something in between would better satisfy eye and nature— perhaps by encouraging clover in turf, for clover…

Dutch white clover crouches low

Dutch white clover crouches low

… needing no polluting chemicals, provides its own nitrogen fertilizer which improves soil quality,

… has deep roots that require less watering so it stays green even in drought,

… produces pretty blossoms to attract pollinators and doesn’t need to be reseeded,

honey bee visiting red clover… only slowly invades lawns and their borders,

… grows companionably with grasses while helping to squeeze out unwanted weeds,

… doesn’t yellow in our winters like Bermuda and other warm season grasses,

crimson clover is taller for a wilder-look

crimson clover is taller for a wilder-look

… doesn’t brown like grass where pets pee,

… tolerates the shade of trees where grasses struggle to grow,

… and looks lush the year round.

I know gardeners who will huff at this attempt to promote clover, but the monoculture lawn became fashionable only recently and will hopefully yield to esthetics and ecology. Pollock’s Blue Poles was purchased for a modest sum amid much controversy by the National Gallery of Australia in 1973, but it is now displayed in pride of place and worth anything up to $100M. As clover gradually colonizes the lawn I think our garden is going to look a million dollars.
