Not illustrated are the family of three Spotted Flycatchers and the Redstart surprisingly seen in a Sussex hedge! At this time of year they could easily be migrants from somewhere further north, of course. The Peregrine falcon that had a go at a Rook, however, was probably a local.
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.
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”.
One of the real difficulties in nature conservation is the basic fact that humans have short lives and shorter memories.
We instinctively assume that the way the countryside “should” look is … how it looked when we were young. Obviously, it had been that way since time immemorial, at least since the year 1 B.M. (where B.M. means “Before Me”). In Feral, George Monbiot calls this “Shifting Baseline Syndrome” – each new generation sets the baseline to the time of its own youth: we imagine our childhood landscape to have been just right, good, and natural.
Only it wasn’t. Our limited time horizon obscures the fact that the countryside has been changing continuously since Roman times, indeed since the Stone Age. Forests have been felled, making way for fields, towns, and roads. Already by 1000 AD, most of Britain’s forests had disappeared, and our larger forest animals like bear, wolf, lynx and wolverine were disappearing with them.
But even in a single lifetime, the loss of once-familiar species is shockingly evident. I had a small reminder when I found one of my birdwatching notebooks from my schooldays. We had been on a Natural History Society trip to Portland Bill, where we stayed in the old lighthouse, a bird observatory in a fine location for counting (and trapping and ringing) arriving and departing migrants. A group of us walked out in the bright sunshine on 1 September 1972, and I listed what we saw.
I was pleased to see a Raven, a Garden Warbler, and a Kittiwake, as I would be today, though all these species are doing well. I was reasonably pleased to hear a Little Owl, something that would now be rather special. I was quite unsurprised to see 20 House Sparrows, and I don’t seem to have found the Turtle Dove or the Redstart at all remarkable. Either of those would now be close to the highlight of the year: and the Song Thrush too, once a regular garden bird, has become really rather uncommon. Then there are the Skylark and Whinchat, which I gave no more notice to than the Linnet, Jackdaw and Stonechat; and the Sand Martin too is declining alarmingly. The 39 Goldfinches, on the other hand, were somewhat remarkable to me then, but I see nearly as many in flocks around the quieter streets in town. I didn’t think the presence of 5 warblers worth noting, though at least that isn’t too terribly difficult to achieve today – just a matter of going to a reasonably decent nature reserve, as there won’t be many species on farmland (you’re lucky to get Chiffchaff and Blackcap, really). The mixture of farmland species, birds of open moorland (Meadow Pipit, Wheatear), and coastal species (Shag, Kittiwake, Rock Pipit) is far more remarkable than I realised at the time, and is probably characteristic of those headlands where migrants congregate.
It would be interesting to repeat the walk early in September (or in the spring migration) and see what we’d see. I think there would be fewer species. And a lot fewer sparrows.
It was suddenly summer again this morning, so I packed cameras, binoculars and a sandwich and went down to Thursley in glittering sunshine. This photo perhaps catches something of the dazzle and sparkle of the bog pools and their shimmering guardians: a pair of Keeled Skimmers (Orthetrum coerulescens) are flying over the water; she is darting down to lay eggs, he is hovering above, guarding her from other males. Their wings sparkle and flash, and it is amazingly difficult to follow, frame, focus and shoot fast enough to get anything like a decent picture. But I rather like the motion blur in this one, and if it’s not perfectly in focus, you know why. I hope you like it too.
I was pleased, too, with this shot of an Emerald Damselfly, the sparkling water behind it forming a pattern of pleasantly out-of-focus circles.
There were quite a few Small Red Damselflies about, mostly single but a few egg-laying pairs; and a modest number of blues, most likely Azures.
Apart from the hundreds of Keeled Skimmers, other dragonflies included Common Darter, Black Darter (I only saw a few females today), Black-Tailed Skimmer (just one), and Southern Hawker.
We saw few butterflies apart from Large Skippers which bustled about flowers near the boardwalk, and little Gatekeepers (I do mean they were smaller than usual) … until we arrived on the amazing Parish Meadow that was once a dump for emptying cesspits. Now it has an ecology strikingly unlike the rest of Thursley Common.
The meadow was full of Meadow Browns, Graylings (mating), Ringlets, Essex Skippers, a Brimstone, Large and Small Whites, and … a Purple Hairstreak (about the Oak trees). The rabbit-bitten pasture, dotted with little flower-stalks of Centaury, was thick with Ragwort, which in turn was richly covered with Cantharid beetles, solitary bees, wasps, and hoverflies and other Diptera. We put up a Silver Y moth which obligingly landed in front of us and perched in the open. We found the traces of a Green Woodpecker killed by a Sparrowhawk; but happily saw a live one in the Oaks nearby.
The boardwalks were busy with Lizards and Skimmers sunning themselves.
We met a local group of birders, complete with masses of tripods, telescopes and cameras, and asked if they were looking at the Stonechats. No, they replied, the Hobbies, there are three. We looked up, and sure enough there were three raptors. But in our binoculars, they turned out to be a Kestrel, a Hobby, and a Red Kite! Perhaps there were some more Hobbies somewhere else.
A little way further, absent the birders, we found a dead tree with some juvenile birds perched about it, and a lot of twittering. Yeah, a typical Chiswick Cafe. Some of them were young Redstarts; the others, young Stonechats: pretty confusing. But the Redstarts flew up into a Pine tree – not a Stonechatty thing to do – and sure enough, there was an adult Redstart on a lower branch, plain to see. And a Stonechat adult rasped out its grating call over to the right.
In a group of tall Oaks, we sat and ate a sandwich; and a Spotted Flycatcher flew across and perched on a high dead branch. It spent five minutes looking about, twisting its neck remarkably, but making no sallies. When I was a boy I saw them in the garden every summer; now they’re really something special, like, er, Starlings and House Sparrows.
The sandy heath paths were full of little holes dug by Ammophila Sand-Wasps, and others made by Philanthus Bee-Wolves (or Bee-Killer Wasps). Both are called digger wasps (“Sphecidae”) in most books, and it’s certainly a good name, but the family has been split up, so Philanthus is now in the Crabronidae, which contains most of the old “Sphecidae” (we’ll have to say sensu lato for this); the new Sphecidae (sensu stricto) only contains what used to be the Sphecinae, which includes Ammophila. Rich scope for confusion. Sphex is the ancient Greek word for wasp, and it’s interesting that Linnaeus chose this word for a digger wasp rather than the social wasps, which have the Latin name Vespa for the hornet, and Vespula, little wasp, for common wasps.
Out of a low bush of willow and gorse right beside a boardwalk came a strange, quiet but insistent squawky chatter of alarm. Peering in between the branches, a small slim dark bird with a long dark tail could be seen hopping about anxiously: a Dartford Warbler. It was extraordinary to be within a few feet of this shy, rare and retiring bird, and watching it for several minutes. There are actually quite a few on the heaths of Surrey and the south coast, but they’re never easy to see—most of my views have been of disappearing rear ends, diving into gorse bushes.
