The usually clear lake was covered in thick green patches of weed, enough for Coots to be able to walk on.
Radical path clearance
The path, too, looked rather different, with many of the large creaky poplars cut down leaving a wide unfamiliar swath of bulldozed path. The poplars constantly drop branches and fall over so it was about time.
Green-Veined White on Stinging Nettle
There were not many insects about – Emperor Dragonfly, Migrant Hawker, Common Blue Damselfly (with the ace-of-spades on segment 1 of the abdomen), Green-Veined White, a few Speckled Wood was about it.
Himalayan Balsam
I don’t recall seeing much of that troublesome weed of nature reserves, the Himalayan Balsam, but it was evident in cleared areas. Shame it’s a nuisance, as it’s rather a beautiful plant.
Someone’s been eating Cherries…Agrimony in flower and burrs
Warm September weather usually means no migrants as they all settle down to enjoy the last bit of summer before moving. I heard a Cetti’s Warbler and a brief unseasonal burst of Chiffchaff song; I think I glimpsed a Blackcap diving from a patch of Teasels back to its bush. A few Jays shrieked and flapped butterfly-like across the horse pasture. A lone Kestrel flew lazily to perch in a tree. On the water, not much apart from Coots, a Mute Swan, Mallard, a family of Egyptian Geese, some Cormorants (quite a few of them with a lot of white on their fronts).
An Apple tree glowed with nice ripe fruit; someone had beaten a path under it to do a little picking.
When a chilly east wind drops and the sky clears to a brilliant blue in February, it is a shame not to drop everything and rush outside to enjoy it. So I found myself down at Wraysbury Lakes, all wrapped up in my winter clothes — but my gloves never left my pockets, and my jacket and pullover were soon unzipped as the temperature climbed to 9.5 C, and in the sun with scarcely a breeze (the planes returned to their usual takeoff towards the west) it felt far warmer than that.
White bracket fungi on fallen Poplar
Some handsome white bracket fungi shone in the sun; they were triangular in section with flattened tops, slightly toothed beneath. Could be a Trametes or Tyromyces perhaps.
On the lake, half a dozen Goldeneye were all that were left of the more ‘special’ ducks; a male joined the party, and a female swam rapidly up to him, bobbing her head; he bobbed back, and threw his head over his back too. Spring is in the air. It looked as if they were already a pair, I’d say.
Also on the lake were some handsome Pochard, mostly asleep, one diving and surfacing, and a Shoveler, preening. A Heron flew slowly over, half a wingspan from the water. A Field Mouse ran right in front of me and down to the waterside by the willows, and obligingly fed in the open for a minute while I watched with binoculars on close focus: the long tail, round ears and quivering ‘whiskers’ (vibrissae) at work.
Away from the lakes, a Rabbit hopped across the path. A Mistle Thrush called harshly; another flew past; a solitary Fieldfare left over from the sizeable flock a week or two ago.
I wandered down to the confluence of the Colne with the Thames; a Kingfisher gave me a good of that always astonishing turquoise bolt of blue lightning, flashing on short triangular wings over the little river. A minute later, it flashed back upstream, as startling as before. A single green sphere of Mistletoe clung to the leafless canopy of a tree behind the industrial estate.
Winter has definitely set in. The spinach beet in my garden was all frozen, the air at -3 Celsius and the ground presumably rather colder under a clear night sky. Fearing it might all be lost, I picked some and went out to see what there might be today down at Wraysbury Lakes.
Almost the first thing I saw was a bulky little finch high in a waterside willow. It called ‘deu’ quite loudly, fidgeted about and flew before I could focus on it. Still, there was no doubt it was a Bullfinch: the call, its shape, its solitary habits, and its shyness all pointing the same way. It is never an easy bird to see, even where it is resident (it is regularly ringed at Wraysbury). Leafless trees and the rising energy of the coming breeding season provide one of the few opportunities to catch a glimpse of this less well known finch.
At first sight there seemed to be no birds out on the lake. Finding a small illicit patch cleared by a fisherman I set up the telescope and looked about. A Pochard or two; some Tufted Duck and Coot; a male Goldeneye… but the Smew and Goosander of a week or two ago were nowhere to be seen. The old truth is that you never know what you’ll see: but it’s often a delightful surprise, and almost always energizing to be out in nature.
I walked on and looked about again: some rather white ducks caught my eye in the distance. Two male Goldeneye, each with a female in tow. The males threw their heads forward a few times, pretended to preen; one threw his head back and forth, then lowered his head and stretched it out and in. His female swam after him, her head resting on her back as if she were asleep! But she was certainly watching the display, and swimming to keep up a few lengths behind.
A loud squawk betrayed a Heron; it flapped out of cover at the end of the lake and landed on the bank behind the ducks. A few Mallard panicked from the water below me; a Moorhen briefly took flight.
Away from the lake, a few Robin and Dunnock hopped in and out of the bushes. A solitary Fieldfare or two gave their chack-chack call from the hawthorns, watchful and flighty. Another Bullfinch calling, this time atop a bare hawthorn bush – or maybe the same bird, half a mile on – and again I couldn’t get binoculars on to it, despite my stealthiest movements: it had surely seen me at once, and just took a few seconds to decide when to flee.
A Kestrel hovered beyond the tall poplars: no Buzzards or Red Kites today, but really the Kestrel feels almost more special than them, its numbers declining across Britain.
A few Jackdaws, Carrion Crows and Wood Pigeons on the horses’ hill; some Fieldfares in the trees, with a single Redwing; a Stock Dove flying low.
After a chilly grey start, the clouds dispersed and it turned into a brilliant winter’s day, the sky crisp blue, the air clear. I grabbed the telescope and went down to Wraysbury to see if the winter ducks had finally arrived.
Snapped tree (Poplar) over path
The first thing I saw was a sign of the violence of the recent storms; a Poplar, always a fast-growing and short-lived tree, had snapped off and fallen over the path. But a way had already been cut beneath it.
Soapy Pollution in River Colne
The next sight was a sad one: for the first time I can remember, the River Colne was obviously polluted, with lumps of foam drifting rapidly by, or caught on branches in the normally clean water. The river supports Kingfishers, wagtails and assorted waterfowl, so I hope the cause is a brief one-off event.
On the lake were four or five Goldeneye, the males waving their heads up and down to signal to the females – or to warn off rival males – the bold white patches on the sides of their heads visible without binoculars.
A little further on was a small party of Goosander, a male and two redhead females, their long serrated hooked bills and distinctive long bodies instantly recognisable, a sign of winter in this part of the world as they come down from their chillier breeding grounds.
Then, just as I was moving on, the bold whiteness of a male Smew caught my eye. With him was a redhead female, both ducks far smaller and shorter than the rather big Goosanders. A few grebes and tufted ducks vied unsuccessfully for my attention.
Ramalina lichen on Poplar
Some of the poplars, half-fallen, offered normally out-of-reach branches for close inspection. Along with the usual Common Orange Lichen and the grey leafy lichens (Parmelia sulcata and such) were a few bristly tufts of Ramalina, easily told for being rather stiff, slightly forked, and the same grey-green on both sides. You’ll probably have seen the genus on rocks just above the high-tide mark by the sea, or on big old stone-age megaliths. It’s a lichen that demands clean air, so it’s rather a nice surprise to see it so close to Heathrow Airport. Perhaps the prevailing Westerly winds keep most of the atmospheric pollution away. There is no doubt, though, that London’s air quality is far better than it was a generation ago: hardly anyone burns sulphurous coal any longer, and while there are hotspots of nitrogen oxides (Heathrow for one, Oxford Street for another) and diesel particulates, these aren’t as harmful to lichens as sulphur dioxide was.
Red Kite
Around the corner into the area of wet grassland and scrub, I was delighted to be surprised by two Red Kites circling silently overhead against the brilliant blue, their long wings and forked tails a welcome sight that would have been familiar to Shakespeare but was missing until their recent reintroduction to lowland Britain. There was plenty of professional angst about whether the new Chiltern population should be encouraged to interbreed with the remnant Welsh population: but in the event, the birds easily dispersed the couple of hundred miles involved, and soon the gene pools mixed all by themselves.
Ponies and Hay
Up on the smooth green hill that was the old rubbish mountain and is now home to a dozen ponies and horses, the distant chack-chack of Fieldfares drifted to my ears. At least fifty of them were standing, watchful but constantly feeding, on the bare grass, flying up and chattering at the least warning. A solitary Mistle Thrush stood big and grey with its boldly spotted breast among them; a flock of a hundred Starlings moved flightily between trees and grass. A Wood Pigeon panicked and all the Fieldfares flew into the trees, still chacking. I splashed through the ankle-deep mud and puddles on the somewhat flooded path to the road.
Finally, right at the end of November, autumn is starting to look something like winter. Even now, and even with a light easterly wind, it is mild, almost too warm for any sort of winter coat.
Pochard, here for the winter
But winter flocks of birds have at last arrived: 45 Pochard on the lake, handsome with their reddish heads contrasting with pale grey backs; dozens of Goldfinch in the nearly leafless trees, twittering ceaselessly; a dozen or more Fieldfare in the thorn bushes in the horse field; a few Redwing in another thorn bush.
My first flock of Redwing this winter
The low sun made the dried flowerheads of the Teasels beautiful. A single Pleated Inkcap gleamed among the short grass and muddy hoofprints.
On an incredibly warm afternoon for the end of September (26° C), I went for a walk around Wraysbury Lakes, not expecting to find much: nearly all flowers should be over by now; it’s too warm for most birds to bother migrating south for the winter; insects and birds have mainly finished their showy summer breeding season; the winter ducks will not yet have arrived from the north. So I determined to relax and enjoy whatever might turn up, if anything.
There were not many ducks on the lake: mostly Tufted, a few Mallard, but 13 shy Gadwall under the far bank. A couple of Great Crested Grebes, a Heron, and a family group of cygnets made up the waterfowl, but for a party of a dozen Cormorants flying past. There were no gulls except a few Black-Headed. For the warblers, a couple of Cetti’s sang briefly; something churred once; and a few Chiffchaffs called.
Banded Snails on dried Hogweed: there are 5 in the photo
The hogweed had almost all formed its fruiting umbels and dried up, though one or two latecomers were still in full leaf. The dry stalks each had at least one banded snail parked up: some had 5 or more. So I thought I’d photograph each snail and, unusually for a nature blog, do a little rather random science and try to count the numbers in each colour variety. For the white-lipped banded land snail is rather delightfully polymorphic. I imaged 37 snails, all those I could reach, so they were probably a fair sample, unless you think there were some better-camouflaged ones I didn’t notice: I doubt that as all of them were high up on the stalks. Here are a few of them to illustrate some of the colour variation.
Polymorphism in White-Lipped Banded Land Snail
I counted:
2 yellow ( unstriped), 5%
16 yellow with brown stripes, 43%
15 white with black stripes, 40%
4 black, with an obvious broad fused stripe, 11%
Actually the stripes and background vary fairly continuously so a better way of dividing them up would be necessary. All the same, it’s fun to see just how convincing the polymorphism is. I didn’t see any dark-lipped snails (another species), by the way, and only a couple of snails of other species.
A small Pedunculate Oak had dozens of spangle galls under its leaves; these are caused by tiny wasps that live inside them.
Spangle Galls on Pedunculate Oak
A few dragonflies were still about: one Emperor; a few Hawkers, probably the Migrant Hawker; one smaller species, likely a Darter; and one Common Blue Damselfly.
The teasels, like the hogweed, had all fruited and dried out, forming a handsome pattern against the sky with their bristly pineapples on spiky stalks.
Teasels
Rose hips and hawthorn haws proclaimed Autumn, season of mists and mellow fruitfulness: contradicted by the humid heat of the day.
Round on the reclaimed landfill hill, it was a pleasure to see the low five-petalled cinquefoils in the horse-nibbled grass.
Potentilla (cinquefoil)
The surprise of the day came almost at the end of the walk: a party of perhaps fifty Meadow Pipits, shyly calling see-see-see as they swept up from the meadow, flashing their white outer tail feathers: the same species I had seen all over the moors of Badenoch and Strathspey, 500 miles to the north. It felt a little strange to see them passing by here.
For a day when I didn’t expect to see much, I think I did pretty well.
I had a beautiful, peaceful, sunny summer walk down at Wraysbury Lakes. Away from the roar of the traffic and the enormous queues brought on by roadworks and summer weekend commuting, I was surrounded by fluttering, glittering, shimmering Banded Demoiselle males, and on the vegetation also the gloriously iridescent green females, their clear green wings like fine lace dress trimmings to accompany their dazzling emerald-jewelled and enamelled bodies.
Common Blue damselfly pair in cop
As well, Common Blue damselflies basked in the sun; a few pairs in cop carried out their incredibly complicated sex act, all claspers (male tail to female neck, female tail to male belly with its spermatophore and secondary sexual organs, forming the startling ‘heart’ or ‘wheel’, in which the pair can, at a pinch, fly like synchronised swimmers.
At first I thought there were no warblers about, but gradually little bursts of song punctuated the afternoon, and by the end I had heard six warbler species, and good binocular views of three of them (Garden Warbler, Whitethroat and Willow Warbler).
There were some handsome Ichneumons about, but perhaps the insect I was most surprised to see was a Small Tortoiseshell butterfly. When I was a boy these were so common as to be unremarkable – as were House Sparrows, Starlings and Yellowhammers. It is almost a shock to discover that seeing just one is now a rare treat: more nostalgic than pleasurable, perhaps. Much work needs to be done on landscape-scale and farmland conservation to bring back our common butterflies.
May is the fastest time of Nature’s year. What a difference a few days make! Last time at Wraysbury, a few sluggish mayflies sitting around as if waiting for something to happen in a one horse town.
Well, today it’s happening. In places, the sky is filled with rising mayflies: a few mating, most alone. Here and there, some repeatedly dance up, and a few seconds later, down; but most just climb, and fly about, seeming frail on their large wings, their triple tail streamers hanging below them: it’s worth zooming in on the picture. Even better, here’s a short video clip. The soundtrack combines an airliner taking off and a Blackcap singing.
Male Banded Demoiselle on Bramble
One of the glories of summer by water is the brilliant turquoise and green iridescence of the male Banded Demoiselle – the so-called band is actually the appearance of flickering of the wings, the dark spot on each of the four wings giving a hard-to-describe semblance of a sparkling blue jewel in flight, with bands of colour too fast and changeable for the eye to understand. But he’s pretty fine at rest, too.
Male Common Blue Damselfly
Common Blue, Bluetail, and Red-eyed Damselflies have all now emerged, the Red-eyed being the scarcest of the three, seemingly.
Soldier Beetle, Cantharis rustica on Cow Parsley
On the Cow Parsley were, as well as the damsels, two cantharid Soldier Beetles, Cantharis rustica or a close relative. Another enormous cloud of rising mayflies, and suddenly behind them a pair of Hobbies, hawking for insects – whether damselflies or even mayflies is impossible to tell. One comes close, wheels away on scything wings as it sees me.
Silver-Ground Carpet Moth Xanthorhoe montanata
A Silver-Ground Carpet Moth, Xanthorhoe montanata, flutters weakly past me among the Hawthorn bushes and flops onto the grass. Garden Warblers sing, a Whitethroat rasps in its songflight. A Treecreeper sings its little ditty sweetly from near the river.
On the hill, three Greylag and two Egyptian Geese form a peaceful flock. Stock Doves and a mixed flock of Crows and Jackdaws rise from the grass. A Song Thrush gives a marvellous solo recital near the road.
A high pressure zone is bringing bright and mainly sunny weather to Britain, but as it’s not overhead it is also bringing quite a cold breeze. Down at Wraysbury Lakes, all the winter ducks have left, with just Tufted, Mallard and a pair of Gadwall remaining. Two Great Crested Grebes wandered around each other, not quite getting into a courtship dance.
Things were more exciting on the birdsong front. Blackcaps and Chiffchaffs sang sweetly all over. A Cetti’s sang very loud, very close by the lakeside as always, first in front … I stalked up very quietly … and then behind me. Invisible, the skulker. In the thicker scrub, several Whitethroats sang their scratchy short song, the first this year; and at least three Willow Warblers sang their descending scales, also the first of the year. And, briefly, one Garden Warbler gave me a burst of his even, musical tunefulness. There’s often a Sedge Warbler near the river but not apparently today. More song came from the Robins, a Song Thrush, and a Chaffinch or two.
Overhead, a Grey Heron circled upwards towards a Boeing 747-400 and did its best to resemble a soaring stork or crane, quite impressive really with broad, downcurved wings rather like one of those air-filled kites made only of light cloth.
St George’s Mushroom
A small patch of St George’s Mushrooms nestled among the Potentilla leaves by the path; it’s about the only edible mushroom at this time of year, but I don’t pick them, both for conservation reasons and because I’m not keen on their rather mealy taste.
The first Speckled Wood butterflies of the year are in evidence; they are fiercely territorial already, chasing off numerous Peacock butterflies. A few Green-Veined Whites settled, frail and shy, on the thicker herbs.
Ground Ivy
Great patches, almost carpets of Ground Ivy, which sounds a lowly herb, but looks glorious among the low-cropped grass, shining in the sunshine. It’s in the Labiate or Mint family, and has pretty rather short toothed leaves, purple-tinged, with attractive blue lipped flowers that are really quite orchid-like if you ignore their long tubes.
We had summer already. Yes, in March. It was baking hot for two weeks, then it ended as suddenly as it began. Then we had spring: the grass started to grow; the gooseberry bush is covered in its fresh green dress; the cherry trees in the streets are glowing with white and pink blossom; now the plum tree too is following with its delicate white flowers.
I grabbed my binoculars and went down to Wraysbury Lakes to see if any warblers had arrived. Even from the road I could hear a Chiffchaff singing; there were at least 10 singing around the lake, so plenty of migrant birds must have arrived to join any hardy overwinterers in the springtime. A Cetti’s Warbler, too, sang its loud brief song from the waterside. But no other warblers, yet; the chorus included a Song Thrush as well as the usual small birds, Great Tits making an odd rasping noise today (nothing like the typical ticha-ticha-ticha call), Robins, Dunnocks, Wrens, a Blackbird.
On the water, I had a surprise: there were two female Goldeneye still present, and a handsome male not far from them. Their biological clocks are still on the ‘Winter’ setting, clearly; their far northern breeding grounds guaranteed to be bitterly cold, devoid of food so early in the year. And near them, two pairs of Pochard, the handsomely rufous-headed males gleaming in the bright sunshine.
A loud splashing alerted me to the presence of an aggressive Mute Swan, its neck folded back, its wings raised threateningly; it had flown a short distance to warn off a rival male, which did its best to appear unconcerned. They both swam very fast, repeating the flying off a short distance (the rival) and noisily giving chase (the threatener) three times. Eventually the rival decided he had saved face enough, and flew off a hundred metres or so, leaving most of the lake to the victor.
I turned to walk on, and out of the blue sky came a minute’s hail, the grains about 5 mm across, pattering cleanly on to the ground. The wind freshened to force 4 from the southwest, feeling wintry on my ears; presumably up at Cumulus cloud level, the wind was strong enough to carry the hail some distance sideways from where it had formed.
The English seem unemotional … except for their passion for nature
