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.

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.

Definitely not a Jack Snipe

This morning dawned bright and crisp, all the car windscreens covered in frost (the air 1.8 Celsius). In the garden, a Chiffchaff was singing, not a bird that often visits here: probably it has only just flown in from Africa.

Constrained to stay indoors all morning, I managed to get out to the Wetland Centre in the afternoon. There was a buzz of excitement in the hide, faces and optics jammed up against the windows, notebooks at the ready: someone had seen a Jack Snipe. A young man with a Canon SLR camera and a cream-coloured telephoto lens asked if I knew the difference between the Jack and the Common Snipe. Er, I said. It has shorter legs, a shorter bill, no pale stripe on its crown, and it bobs up and down a lot. He looked just a tiny bit embarrassed. Could I tell from a photograph? I went over and peered into the bright little screen. The crown, striped or not, was not in view; half the beak was in the mud; and the legs were bent and seemed … shortish. I said I couldn’t tell and did he have another photo. He apologised, the next one was overexposed. To me, it looked much more like a Common Snipe. Where did he see it? He pointed down, where I’d seen a Common Snipe zigzag in across the water and land. I said I thought it was probably a Common Snipe: he hadn’t seen it bobbing up and down? He thought not. I observed that the light was difficult, as the sun kept on coming out of a cloud, and the water varied from dazzling to nearly black in the reflections; did he bracket the exposures? He said yes, it would be a good idea. He took some more photos, said he had a nice one against the dark water. I looked into the screen again: it was true, the contrast of the sunlit brown-and-cream of the camouflaged plumage and the velvet-black water was quite lovely. I smiled and murmured that it was beautiful, but definitely not a Jack Snipe. We had both enjoyed seeing the commoner species, so close, so bright, so crisply patterned, in such fresh spring weather.

I left the hide and walked quietly around the sheltered lagoon. On the grassy bank, a Green Woodpecker’s red cap and black moustache – it was a female – caught my attention. The way the woodpecker was probing quickly in the soft ground with her long pointed beak, then bobbing up to take a quick look around for possible predators, was remarkably snipe-like. I suppose the problem of feeding on something buried a distance beneath the surface pretty much guarantees you are going to be vulnerable while your beak is jammed into the mud and you are busy feeling with your tongue to decide if you’ve caught something edible… your attention is simply not going to be on the sky for those moments. It was curious to feel the similarity between two such different birds as the big hole-dwelling woodpecker with its jolly green and yellow plumage and its black and red face markings,  and the plump little snipe with its marvellously cryptic brown and cream camouflage jacket, and an absurdly long beak. Each was delightful; but definitely not a Jack Snipe.

Summer, Spring, Winter … in a day

Large Cumulus at Wraysbury
Large Cumulus at Wraysbury

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.

Slimbridge, home of Peter Scott’s original ‘Severn Wildfowl Trust’

Flamingoes at Slimbridge

I had the good luck to be able to visit Slimbridge this week with a friend. Back in 1946, Peter Scott founded the ‘Severn Wildfowl Trust’, setting up an observatory to study the White-fronted Geese and the Bewick’s Swans, and to help save other wildfowl from extinction. The geese and swans happily remain on the reserve today; there were 20 Whitefronts, as well as a hundred or more Barnacle Geese out on the marsh, not to mention plenty of Greylags and Canada Geese in the bright sunshine on the scrape.  And as the sun sank in the western sky, the collection Flamingos glowed in the warm light – no need for Photoshop tricks there.

The star of the show, though, was one of the European Cranes, tall and elegant with its tail ‘bustle’ like an late Victorian lady’s; incongruously, it was also wearing a radio transmitter and three coloured rings, such has been the excitement at the raising of these rare British birds from the egg, and allowing them to fly off as wild birds – only for one or two to pay a return visit. Meanwhile, a genuinely wild flock of cranes has established itself in Norfolk, so Britain once again has this beautiful and distinctive species breeding in its wetlands. The number of places, even near London, with ‘crane’ in their names is striking – Cranfield, Cranbrook, Cranford to name a few. I once imagined this was simply a confusion or word-shift, the bird having been a grey heron all along: but no, cranes were once common, as were wetlands and damp flowery meadows. Let’s hope they will be again.
