Among the wonderful moments on this walk: a heron gave its cronking call and flapped slow over the water; a plane passed behind three cormorants drying their wings, perched on the branches of a dead tree; a group of goldeneyes panicked and pattered across the lake, gaining speed for takeoff, giving their high-pitched call, the waves sparkling in the slanting sunshine; a song thrush tentatively singing its repeated music; a solitary fieldfare.
It was a glorious winter morning at Wraysbury Lakes. The lakes themselves held few birds, but the Goldeneyes had arrived with the recent cold weather, and the males were giving their fine trumpeting call (they’re not called “clangula” for nothing, the duck with the resounding bell-like music) and displaying, too.
A few herons flapped lazily over the water; a small group of tits hopped through the bushes. My first fieldfares of the winter chack-chacked in the willows and obligingly gave good views of their handsome brown-and-grey plumage.
A sparrowhawk raced very low over the meadow. On the way home, a peregrine falcon perched on a streetlight.
The day was exceptionally warm after the chilly winter weather. The hedgerow plants dripped gently. I liked the colours and light on these blackened rose-hips, still somehow looking invitingly fruity.
The path too was covered in blackened leaves, wet and slippery. On the lake, half-a-dozen Goldeneye, a couple of Pochard, a few Teal, some Tufted Duck, a few Mallard. Apart from the ducks, a couple of Cormorants, two young and very white Great Crested Grebes. On the meadows, a Green Woodpecker, flocks of Goldfinches, scattered Redwing and Fieldfare, a flock of Carrion Crows.
With another day of freezing fog, very dangerous on the roads, nature is telling us that, yes, global warming or no, it’s winter. The false acacia, totally leafless, whirs with activity. A big wood pigeon sits impassively, ignoring the small passers-by. Within a few minutes, these include 3 goldfinches, keeping well away from each other in the branches; 2 male blackbirds, similarly, their heads high on the lookout for competitive activity; 4 ring-necked parakeets, never settling for more than a moment, jumping up squawking at the slightest provocation; 2 redwings, handsome with their contrasting eyestripes; 1 fieldfare, markedly bigger, and a handsome bird when seen in crisp winter sunshine rather than today’s murky fog. A few minutes later, a blackcap appeared: still a bird that we think of as a summer visitor, though a few pass through in winter from colder places. Later still, a great tit jumped in and wriggled about; and a little flock of 6 starlings blew in for a few minutes, sadly diminished from the sort of flocks I remember: and even this local flock used to have 7 members.
The effect as birds appear from and vanish into the gloom is rather of one of those popular tales physicists tell to try to make the public feel they understand what nuclear physics is all about: particles and antiparticles are ceaselessly created by the vacuum, and as continuously meet each other and annihilate, returning to their matrix, the apparently endlessly creative fog, which one would otherwise have mistaken for chilly nothingness.
After the bitter cold of the New Year, down to a surprising -12C in London, suddenly spring (as it were) is back in the air, and the Daffodils are resuming their progress towards full bloom in gardens and on roadsides.
The warmth and sunshine tempted me out to Wraysbury. With the heavy rain and perhaps also the rapid changes of temperature, a large Poplar had fallen across the river, forming a minor weir.
On the path, a Muntjac deer had left its tiny prints in the soft mud. Unlike a lot of other mammals, at least this one is readily identifiable from its print, the two small sharp slots of its slim feet not mistakable for anything else.
The lake, which had been full of birds as big as Swans last time I visited, was almost empty: a few Coots, some Great Crested Grebes, a Black-Headed Gull, a few roosting Cormorants, a few Tufted: and happily two of the area’s specialities, three pairs of Goosander, and nine Goldeneye (including three males).
A Kestrel hovered and dropped slowly after a small mammal in the long grass. A Redwing flickered away around a corner. A Song Thrush sang sweetly from a thicket. One or perhaps two Bullfinches gave their distinctive “Deu” call from the middle of a bush. Half-a-dozen Fieldfares chattered and skittered about from the top of one bare thornbush to another. A few Wood pigeons and Crows looked out warily.
A twittering, constantly moving flock of a dozen Goldfinches greeted my arrival at Wraysbury. The wind was already keen and I was glad of my thick fleece and waterproof jacket. A few Wood Pigeons and a Crow or two blew down the wind, hardly needing to flap. Even a Heron, doing its best to flap downwind as usual, rocketed past in the swift airstream. A solitary Fieldfare chattered to me from a bare thorn tree, its chack-chack unmistakable.
The stormy winds of the weekend had broken several large willows including the big one just North of the bridge: two branches had fallen, cracking off what are now revealed to be fragments of the hollow shell of the trunk. Willows and poplars are dangerous as the trunks are short-lived and often rotten inside: and the fast-growing branches can be very thick and heavy.
This tree by the lake snapped its seemingly solid, reassuringly mossy trunk and fell into the water. It was quite hollow, filled with soft brown beetle frass with finger-thick borings. Notice, however, the bracket fungus near the base.
The lake was covered in winter wildfowl, as the Channel at dawn on D-Day was covered with ships. I gave up trying to count the hundreds of Gadwall; there were dozens of Wigeon and Tufted Ducks, and plenty of Mute Swans, Canada Geese and Coots too. A few Cormorants, some with very white bellies, and a Great Crested Grebe or two made up the numbers. As I raised my binoculars, a Kingfisher darted from the near bank and raced right across the lake, perching on the far side.
Suddenly it feels like spring. The migrant warblers haven’t arrived, though a resident Cetti’s gave me a fine burst of its loud simple song; and the winter ducks haven’t all gone back up North, a few Goldeneye and Goosander still fishing the lake; but it was almost warm in the bright sunshine, and the wild pear tree in the woods positively sparkled with fresh new blossom.
There were animal tracks too: tiny footprints of Muntjac.
A little further, a fresh pile of tiny scat, Muntjac for sure.
A Sparrowhawk dashed low over the willows, and disappeared as swiftly as it had arrived.
On the path, the much larger slots of Roe deer; and a Rabbit hopped quietly aside.
The last of the winter thrushes – a flock of Fieldfares – called their chattering chack-chack from the tall boundary hedge of trees. A flock of gently twittering Goldfinches, too, served as a reminder of a winter only just passing.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The low sun made the dried flowerheads of the Teasels beautiful. A single Pleated Inkcap gleamed among the short grass and muddy hoofprints.
