Iridescent Dragonflies, Dazzling Orchids at London Wetland Centre

Bee Orchid
Black-Tailed Skimmer

The whole of the wetland was sparkling with Emperor Dragonflies patrolling the pools: a few females laid eggs by Water-Lilies, the males occasionally chasing prey, or a rival. The margins were full of Azure Damselflies, nearly all males: I saw one pair in wheel formation.

The marshy areas bristled with Southern Marsh Orchids
Red-Eyed Damselfly

Several Red-Eyed Damselfly males displayed on lily-pads, chasing off rivals; occasionally an Azure came by too. Over one or two of the smaller pools, a Hairy Dragonfly patrolled; one of them had an aerial tussle with a similarly-sized red dragonfly, I think a Common Darter.

Yellow Rattle

Overhead, quite a few Sand Martins caught insects over the water (well, the Wetland Centre does sport West London’s only Sand Martin bank, an artificial river cliff), along with a few Swifts, and I think exactly one Swallow … it feels as if something terrible has happened to these populations. They have to migrate across the Sahel, the Sahara, the Mediterranean, and numerous populations of hungry village boys and keen shooters, so it’s something of a miracle there are any left: and that’s not even speaking about climate change.

A couple of Common Terns, presumably those breeding on the Wetland Centre’s lake islands, made their bright and cheery waterbird calls as they wheeled about, searching for glimpses of tiny fish to dive in and catch.

Common Spotted Orchid

There were only a few butterflies about – a Red Admiral, a Holly Blue, a couple of Speckled Wood, some Whites, a female Brimstone. For me, the bees and pollinators looked well down on normal, too. Amidst the warmth of the day, the beauty, the peace, and the brilliant colours, it is a sombre tale of decline.

Palm Tree Trunk: detail of cross-section. What’s missing? There are no annual growth rings! Palms do not have that kind of secondary thickening. Instead, they have masses of tough bundles of fibres (dark brown spots) scattered throughout the trunk.

Well this really is one of those images one captures once in a lifetime. Swift, at dusk, feeding its young, in a crack in the facade of the church of San Matteo, Lecce. The flash has revealed the eye of both the parent and the young bird. Swifts hardly ever land, even sleeping in the air, and they spend as little time as possible at the nest.

Lesser Kestrel, one of dozens in the sky over the 6000-year-old town of Matera. They live socially. The small thumb-winglets (in aeronautics they’d be called leading edge flaps, ornithologists call them alulae) are deployed to increase lift. They appear dark as they are in shadow. The belly is reddish, the wings pale and almost unmarked.

Butterflies in Tuscany

Common Blue [L’icaro o argo azzurro] (Polyommatus icarus) on Lavender beside the swimming pool of the lovely agriturismo farm, Rocca di Cispiano, where we stayed in Chianti. Species names are shown in English [Italian] and (Latin).

Pool area: not an obvious place for butterflies, but the clever planting of a Lavender border made all the difference

Scarce Swallowtail [Il podalirio] (Iphiclides podalirius), a large butterfly with a distinctive sailing flight, taking nectar beside the pool
Silver-Washed Fritillary [La pafia o Tabacco di Spagna o Fritillaria] (Argynnis paphia), a handsome and distinctive species

Tuscan landscape (Chianti): hilltop farms, Vines (bright green rows), Olive trees (blue-gray trees in rows), low mixed maquis (macchia mediterranea) forest, Cypress trees on left skyline

Nine-Spotted Moth [La fegea] (Amata phegea) frequently visited the lavender border and other flowers. It was once also found in England; Chris Manley suggests that global warming might allow it to return (a possible silver lining to that cloud).
Brimstone [La cedronella] (Gonepteryx rhamni)
Hummingbird Hawkmoth [La sfinge del galio o sfinge colibrì] (Macroglossum stellatarum), darting from flower to flower each time just before I managed to focus the little camera …

Bee-fly (neither a bee nor a butterfly) half-hovering to take nectar, making a particularly loud buzz

Meadow Brown [La Giurtina o Maniola comune] (Maniola jurtina)
Red Admiral [L’atalanta] (Vanessa atalanta). It has  a chunk out of its right hindwing, showing it survived an attack.
The enormous, fearsome, but non-aggressive Mammoth Wasp, [La vespa mammuth] (Megascolia maculata), on Wild Artichoke. Presumably its sting would be serious but I can’t find any record of people being stung by this peaceful insect.

A Mammoth Wasp visiting a potted Hottentot Fig, with a wide view of the Tuscan landscape

Oak Yellow Underwing Moth (Catocala nymphagoga) on shower beside pool

The bushes by the pool attracted this Southern White Admiral [Il Silvano azzurro o Piccolo silvano] (Limenitis reducta)
Swallows  [La rondine] (Hirundo rustica) swooping over the pool at sunset. Many pairs nest in the farm buildings; there were two active nests inside our porch.

Perfect butterfly habitat a short walk from the agriturismo: meadow grass by Olive groves with Scabious (blue) and St John’s Wort (yellow). There’s a tiny Queen of Spain Fritillary in the picture!

Sloe Hairstreak [Satiro dell’acacia] (Satyrium acaciae)
Swallowtail [Il macaone] (Papilio machaon); this one at Brolio castle, but there were many near the agriturismo too
Queen of Spain Fritillary [La latonia]  (Issoria lathonia) on Scabious
Clouded Yellow [La crocea, La limoncella, Il postiglione] (Colias croceus) pair in nuptial flight
Marbled White [La galatea] (Melanargia galathea)
Probably Eastern Burnet Moth [La carniolica] (Zygaena cf carniolica) on Scabious.

Zygaena cf carniolica taking flight. The brilliant red underwings give a strong and honest warning signal of the insect’s inedibility.

Eastern Dappled White [L’ausonia] (Euchloe ausonia)

Olive Grove and Spanish Broom. Butterflies skittered about the flowery meadow below the trees.

Wall Brown [La megera] (Lasiommata megera)
A lizard, probably the Common Wall Lizard [Lucertola muraiola] (Podarcis muralis) given its dark chin, scurried along the wooden rail at the edge of the pool area.

A very battered Oak Yellow Underwing that has survived an attack by a bird

Great Banded Grayling [Circe, Satiro circe, Sileno] (Brintesia circe)
Dingy Skipper [Tagete] (Erynnis tages). There were Large Skippers about too, but their habit of perching on slender waving grasses made photography hopeless.
Painted Lady [La vanessa del cardo] (Vanessa cardui)
Spotted Fritillary [La didima] (Melitaea didyma)

Some rather fine wasps apparently attempting to mate

Although it was a bit late in the season for them, we saw half-a-dozen fireflies in the woods by the strada bianca (unmetalled road) and among the olive trees, half an hour or so after sunset.

I made no attempt to photograph birds, but a Hoopoe flew over the pool, and Turtle Doves cooed nearby. A Cuckoo called from far across the valley; a Song Thrush sang; a Green Woodpecker gave its laughing cry. White Wagtails flew up to the roof, and Italian Sparrows hopped about. Goldfinches twittered in the trees. A Sardinian Warbler raced for the cover of the trees, its black crown conspicuous; a Melodious  Warbler sang from the woods. In the night, an owl called, it could have been a Scops Owl. And of course, Cicadas buzzed and Bush Crickets chirped all day long.

Nightingales at Northward Hill

Northward Hill, looking over oakwood, scrub, grazing marshes, and river

Well there are some things one just has to do, even if it means braving the traffic. Nightingales, once common all over the south of England, can now only be heard in a few special places, and Northward Hill is one of them. There are some others in the southeast, like Lodge Hill, and guess what, they want to build houses all over it. Better go and enjoy the birdsong while it lasts.

A very shy Wall Brown, now a mainly coastal butterfly, the first I’ve seen for years

I was greeted by the song of blackbird, chaffinch, robin, song thrush, and wren as I walked in. A few ‘whites’ – large white, orange tip, green-veined white – skittered about as I reached the attractively rough scrub of hawthorn in full May blossom, blackthorn, wild pear, wild plum, and wild cherry, topped by the occasional whitethroat singing away scratchily.

Into the woods, with a handsome old cherry orchard on the right. Some of the oaks were straight out of Lord of the Rings, splendidly gnarled, knobbly, with massive trunks and holes to hide a good few goblins in.

Nightingale country: a fine old Oak. It looks to have been pollarded at about 12 feet up some centuries ago, so it was probably cut to that height while smaller wood was coppiced all around it.

And yes, sure enough, a nightingale obliged by singing its hesitant but amazingly rich and varied song from the thick cover. A little further, another; and a cuckoo kindly sang its unmistakable song from an oak almost in front of me, then with a ‘gok’ call flew, sparrowhawk-like, from the tree, a special sight.

Down to the hide overlooking the pool in the top photo; I wasn’t expecting more than a coot and maybe a mallard, but there were breeding lapwings chasing off the crows; breeding oystercatchers, and an avocet sitting with them; and a couple of solitary little egrets, stalking and stabbing at small fish or frogs. A redshank gave its wild teuk-teuk-teuk call and flashed its wingbar briefly.

Little Egret Stalking

Overhead a few swallows flitted about, and three swifts raced over the marsh.

The Hoo Peninsula is still a wild, spacious, lonely place, even with the swelling villages. You can see the Shard and Canary Wharf in the distance (some 30 miles); the river with its cranes and giant ships is ever-present; but the North Kent Marshes are special, as is Northward Hill with its fine old woods, still unspoilt for birds. Go and see it while you can.

 

 

Thursley Common, not just dragonflies

Red-topped Cladonia floerkana lichens

OK, ok, you wanted some dragonflies. There were masses of Black-Tailed Skimmers chasing about in groups at Pudmore Pond. Black Darters, Common Blue Damselflies, and Small Red Damselflies skittered about the smaller ponds. A large Hawker or two dashed past, unidentifiable, probably Southern Hawker. A Keeled Skimmer perched conveniently nearby, daintier than the Black-Tailed.

Keeled Skimmer

Among the birds, some 50 Swallows were roosting on telegraph wires early in the day. Families of young Stonechats gave grating contact calls, unlike the stone-clicking call of the adults. A Redstart flicked its tail in the bushes. Skylarks rose and sang almost too high to see against the clouds over the heathy hills, Shelley described it perfectly in his ‘To a Skylark’: “a flood of rapture so divine”.

Garden Warblers All Over Watlington Hill!

Prime Garden Warbler Habitat at Watlington Hill

The weather forecast said fine and warm, getting warmer each day. The chalk downs called, so I popped out to Watlington Hill to enjoy the spring sunshine and the birdsong. I wasn’t disappointed: I’ve never SEEN so many Garden Warblers, and I mean seen. Their full, rich warble came from every patch of scrub, sometimes two or three singing at once, and the still mainly leafless trees (the buds just broken) make them visible for once. In binoculars, they are almost evenly soft mouse-brown all over, slightly paler below for countershading, with the merest hint of a little half-collar of pale grey. Sylvia borin has been called “Sylvia boring” by birders, and it’s a good mnemonic, if not much of a joke. They don’t have the Whitethroat’s white throat or patterned tertials; they don’t have the Blackcap’s black cap, or even the Chiffchaff’s eyestripe. All negative descriptions: but their song is both lovely and readily recognisable.

Also singing were Chiffchaff and Blackcap, both in numbers; Blackbird, Mistle Thrush (conspicuously perched atop their respective trees, and calling loudly and ringingly to each other); Dunnock, Great Tit, Blue Tit, Robin, Chaffinch, Wren. From the woods, Jays screeched; a Pheasant called in the distance; a few Swallows caught flies overhead; Buzzard, Stock Dove, Wood Pigeon, Magpie, Jackdaw, and Carrion Crow were about.

The hill is on the west-facing scarp of the chalk (Cretaceous, obviously) of the Chilterns, dropping down to the Oxford Clay plain which stretches away to Didcot and Oxford in the haze. The chalk grass is closely cropped by rabbits, but constantly invaded by hawthorn, blackthorn, whitebeam and bramble scrub.

I was pleased to see some patches of the Dog Lichen in the low turf.

The shadow of a Red Kite passed over the grass, and I looked up. A pair of the long-winged, fork-tailed raptors drifted over the hill, swivelling their tails, their bodies perfectly streamlined and front-weighted like gliders.

Brimstone female

As it warmed up, a Brimstone butterfly appeared, perching on the ground to absorb some heat from the sun. It is one of the most leaf-like of our butterflies, which would suggest camouflage: but they are conspicuous even with closed wings. Perhaps birds see them differently from us.

Spring Surprises: Treecreeper, First Swallows, Ground-Nesting Heron

Ground-Nesting Heron a la Swan
Ground-Nesting Heron a la Swan

Spring is full of surprises, and this Heron, nesting not in a colony up in the trees, but all alone in an abandoned Swan’s nest in a reedbed, is certainly one of them. The London Wetland Centre this morning also boasted a mass of Blackcaps in the “Wildside” woodland, with at least three males and a female actually in sight at once,  along with an obliging Chiffchaff giving me an excellent view, and a characteristically invisible Cetti’s Warbler, shouting out its amazingly loud call. The Silver Birches were in wonderfully fresh green leaf, their bark crisply white against the clear blue of the sky.

Birch in Fresh Green Leaf
“Birches in wonderfully fresh green leaf”

Yesterday, round at Wraysbury Lakes, the same set of three warblers sang, but more elusively. The most delightful surprise was a Treecreeper, not only creeping up the willow branches, but singing its sweetly plaintive little song. This used to be rendered, rather tweely, as “Tree, tree, tree, once more I come to thee”, which does capture the length and rhythm of the song. It is not unlike the Chaffinch’s song, if you know that, but without the twiddly “tissy-cheeooo” ending, and not so firm and harsh. One of the Blackcaps, in the thorn-scrub area, had a fine mimetic song. Out on Horse Hill, the first two Swallows of the year flitted overhead, a solitary Kestrel beat its way against the wind, and half a dozen Jackdaws played and chased in the air, for all the world like a gang of naughty schoolboys.

Indian Summer on Thursley Common

A flock of some fifty Swallows twittered high above the sparkling blue lake among the bog pools. Dragonflies – the occasional Emperor, plenty of small red Common Darters and tiny Black Darters, some Migrant Hawkers – dashed about or sunned themselves on the boardwalks. A pair of Hobbies, those dashing, Swift-winged falcons, soared and watched the Swallows cunningly, waiting for a careless moment. One of the Hobbies swooped down, raced low, agile, among the reeds, up and switchback over a dead tree to snatch a dragonfly on the wing, powered right across the wide bog all the way to the pinewoods. Three pairs of Common Darters in cop, the males leading the females, their claspers about their females’ necks, flew in strict formation like so many Spitfires. A Hobby, high above the bog, accelerated in a long straight shallow dive, for all the world like a Junkers 88 bomber taking careful aim, racing down for a hundred yards at incredible speed to grab a dragonfly: it must have seen its prey all that distance away.

Birch Bog Bolete Leccinum rigidipes
Birch Bog Bolete Leccinum rigidipes

Clusters of the light brown Birch Bog Bolete – yes, it grows under Birches in Sphagnum bogs – are dotted about, their large squarish pores quite unlike the little round holes of the true Cep. Phillips says they’re edible but not worthwhile. This isn’t stopping a pair of plump thirty-something Poles with a sports bag wandering along collecting them (National Nature Reserve? Really?). I greet them, establish their nationality, say my mother used to do the same in the Carpathians and that there aren’t many mushrooms here. The guy with the sports bag shows me a meagre haul of Birch Bog Boletes just about lining the bottom of his bag: he means, he hasn’t found much worth collecting. I try Natsional Natur Reservat and waggle my finger, we part smiling and he shuffles off sheepishly.

Phaeolus schweinitzii (giant polypore)
Phaeolus schweinitzii (giant polypore)

Under some Pine trees, a dead stump, killed by Phaeolus schweinitzii, three or four enormous dinner-plate sized yellow discs, thick and rough with orangey-brown branching tufts: they are overgrown Polypore bracket fungi, dangerous parasites of conifer tree roots. Nobody has given it an English name, which is a pity as the namers could really have fun with it: Yellow Pine Death? Giant Pine Polypore? A magnificent fungus, somewhat alarming if you’re a forester.

On the open sandy heath, some Ammophila sandwasps are still active, perching on the path. A few butterflies – a white, some Speckled Woods, probably a Red Admiral – are about; a very large brown butterfly with agile flight, dancing around a pine trunk and up high, is tantalisingly impossible to get binoculars on, was very probably a Fritillary, in which case it was likely the Silver-Washed Fritillary.

Robber Fly Dysmachus trigonus on Thursley map
Robber Fly Machimus atricapillus on Thursley map

A couple of mean Robber Flies perched on a rather bleached map of the common: they had as Shakespeare said “a lean and hungry look”. They have a tuft of stiff bristles below their antennae to keep their prey from striking them in the head. They wait on a perch – a signboard will do if there’s nothing better – until an unsuspecting fly comes past, then they sally into the air and grab it.

Dordogne: Sunflowers above the riding-stables (17 July 2014)

The riding stables swarmed with young Swallows, perhaps 15 of them growing strong for the flight down to Africa, twittering, swooping, perching on lofty cables.

On the hill, maize and sunflowers grew in glorious profusion, the bees drunk on nectar and coated with yellow pollen.

Along the chalk path, Common Blue butterflies skipped and perched on chicory flowers, delicate blue. In the bushy hedge, masses of darkly glossy plums blooming with pale blue yeast dangled from the trees. Above, a Stonechat rasped out his scraping call. I picked up two stones and made the exact same call by scratching them together, as if lighting a stony match: scritch, scratch. House Sparrows cheeped from the bushes; more anxiously, a yellowish leaf warbler, probably a Melodious Warbler, churred continually and flew about semi-conspicuously to perch repeatedly in the long grass to distract me from its nest – its young continually piping from deep in the hedge. I retreated gracefully.

A Turtle Dove cooed softly from high on a power line. At the stables, a Scarce Swallowtail (actually reasonably common here) drifted past; a White Wagtail hawked for flies beside the manège.

At 4pm the temperature reached 34.5 degrees: such a heatwave is called the Canicule or Dog Days, as Sirius, the Dog Star, is high in the midnight sky at this time of year.

Seven Sea Swallows Don’t Make a Summer …

Down at Wraysbury, I wondered what I might see now the spring migration is well and truly under way. Last year there was a single Cuckoo, a rare treat. And perhaps there would be a good number of warblers already.

The winter ducks had all vanished from the lakes, all bar a pair of shy Gadwall right at the back. There were indeed quite a few warblers about – Chiffchaffs, Blackcaps, Cetti’s, Whitethroats, Garden Warblers and one or two Willow Warblers, all singing lustily. I listened out for a Sedge Warbler to make it Seven but couldn’t find one. Still, not bad going.

But over the lake there was a high call: Pik! Cheer! Cheeri-Cheeri-Cheeri-Cheer! A pair of Common Terns, the first of the year: graceful white ‘sea swallows’, marvellously buoyant in flight. But no – there were two pairs .. no, five birds … no, seven in all. They wheeled and shrieked high above, swooped and delicately took insects from the water surface. Comically, one or two of the Black-Headed Gulls tried to do the same: they looked like tubby Sunday footballers trying gamely to keep up with their mates, flapping heavily, looking rotund and clumsy – yet, these are the same birds that gracefully wheel about the tourists at the Round Pond in Kensington Gardens, skilfully catching pieces of bread tossed into the air at any speed, any angle, any distance. It’s just that the terns are seven times more agile. Their forked tails divide into streamers as long as the rest of the tail; their wings almost pure white below, smooth ash-grey above. Do they make a summer? Almost.

Also swooping over the water was one Swallow, the first of the year for me; and about eight House Martins were hunting above the treetops. Some Alder Flies flew past; perhaps they are emerging from the water, providing a feast for the terns.

One green female Banded Demoiselle perched on some nettles; she too is the first of her kind – indeed, the first dragonfly of any kind – for me this year. And a solitary Greylag goose stood in the shallows, an unusual sight here.

Horses and Jackdaws at Wraysbury
Horses and Jackdaws at Wraysbury

Around the horses on the green grassy hill that used to be the dump, a flock of Jackdaws with some Carrion Crows, benefiting from the insects around the horses; and a second flock, more of a surprise, of Stock Doves. They are notoriously under-reported, people just assuming they are Feral Pigeons or Wood Pigeons without looking to check. They all had the same pattern, and none of them had white wing flashes.

Walking down to the road, the narrow path was carpeted with small teardrop-shaped white petals: Hawthorn flowers, May blossom.
