On a lovely May day, we replaced quite a bit of wooden railing, the rail mainly being fine but several of the posts having rotted at the base.
As we worked, a pair of Brimstone butterflies flew nearby, as well as a few Orange Tips, a Red Admiral, a couple of Holly Blues, and a Large White. It was very pretty among the cow parsley, green alkanet and garlic mustard, with visiting bees and hoverflies. A couple of brilliant metallic green Rose Chafer beetles flew over, just above the tops of the cow parsley.
Around the reserve, newly-fledged robins and jays were hopping about unsteadily. A blackcap sang sweetly; a blackbird, a wren and some robins chattered in alarm from a thicket, mobbing a predator, apparently a magpie — most probably as it threatened to rob a nest of eggs or young.

Above the pond, Azure Damselflies and Large Red Damselflies were in cop and egg-laying (both species); up to three male Small Reds at a time were dashing about in tiny dogfights.
London Wildlife Trust have kindly put on a book launch event for my new book ‘The English Love Affair with Nature‘. The event is free and open to all; though small children may prefer to eat the cakes and go pond-dipping, which will be available on the reserve! Attractions will include me, reading from the book; a chance to buy a signed copy, if that’s your sort of thing; nice things to eat and drink; and the beauty of a nature reserve in May, complete with birds, butterflies, bees, bugs, flowers and trees in new leaf, not to mention mini-beasts, newts and everything that wriggles in pond water! I hope to see you there.
Well, I’d read John Stewart Collis’ marvellous The Worm Forgives the Plough, and his description of the bill-hook as a marvellous tool, but it’s one thing to read about something and quite another to do it with a purpose.
Today, we were tasked with making edges for a stretch of path in the reserve. You can see some lengths of birch trunk lying along the path edge below my left hand. These of course had to be pegged to keep them in place, and then wired and stapled to discourage casual vandalism. The only source of wooden pegs was … more sticks. I set to work with the bill-hook, and indeed the tool is finely adapted to its job. Well-balanced, just heavy enough, and sharp, it slices through wood with a satisfying soft chopping sound. Even so, care and skill are needed, and the job takes a bit of time.
Congregation of Newts
When I had made all the pegs anyone needed, I went for a little nature walk. Down by the pond a now-scarce visitor was singing in the birch trees: a Greenfinch. In the pond, several smooth newts were flicking and darting about. The sun was glinting off the water, as you can see, but it seems two magnificently spotty males were courting a drabber female at the top.
Walking past the main pond, my eye was caught by a striking pattern reminiscent of a brain coral. Lying down on the boardwalk to get the diminutive lens of my phone camera as close to the pond surface as possible, the squiggles resolved themselves into long patterns of jelly divided mostly into hexagonal areolae like miniature cells in a honeycomb, each with a white boundary and a tiny yellow egg at its centre.
At the top left of the photo is a large Ramshorn Snail: several others were nearby, so they are the likely culprits. Generally pond snail egg masses (as laid by the large pointy-spiral pond snail Limnaea) are small, undistinguished jelly-blobs, so these large, impressive structures were a surprise.
The dawn chorus at the reserve revealed two singing Blackcaps: one was alternately feeding on newly-emerged Cherry buds, presumably eating insect larvae, and giving short bursts of song or subsong. In a few days’ time the leaves will make such easy observation much less likely. There were two singing Chiffchaffs, one of them in full view in a Birch just coming into leaf above the main pond; and a Willow Warbler which I first heard yesterday near the picnic meadow.
Identifying a Pug Moth
A party of newly-fledged Great Tits blundered about the bushes on the steps by the main pond, and a Wren gave me a fine view at the ‘mangrove swamp’, which is fast drying up. The newly-dug extension to the seasonal pond has filled with water and is in fact deeper than the rest of the pond, probably a useful variation in depth.
Inspecting the Moth Trap at Gunnersbury Triangle
Up at the hut, the moth trap was being opened after a night’s work. Inside were some Pug moths, probably Brindled Pugs, and a much larger Noctuid moth, an Early Grey.
Also seen were Jay, Magpie, Carrion Crow, Wood Pigeon, singing Dunnock, Blackbird, Robin, Mallard. A Wren was carrying food to its nest near the ramp.
Well, a rarity: this fine beetle, Platystomos albinus, is an Anthribid, a member of a family somewhere between the wood-boring Longhorns and the pointy-nosed Weevils. It has plenty of odd features, not least that it is camouflaged as a bird-dropping. It is “nationally scarce (Nb)” and an “Index of Continuity Species”. This is a male – it’s easy to tell as the species is sexually dimorphic: the males have enormous long antennae nearly the length of the body; the females have antennae about as long as head and thorax together. And this specimen seems (?) to be bleeding from the back of the thorax, possibly an instance of reflex bleeding (autohaemorrhaging) to warn off predators: perhaps the blood is toxic or irritant as it is in several families of beetle. The larvae live in dead standing wood; the adults in fungus-infested Beech or Alder – we have a very few Beech here, and no Alder, and the insect was nowhere near either species.
Cuckmere Haven with bar, lagoon, and wave-cut platform
Down in Sussex for a few days, we walked the Seven Sisters from Cuckmere Haven to the Birling Gap.
We had a taste of the scale of human interference with the world’s climate in the shape of a thick haze of pollution trapped by an anticyclone: on the Weald approaching Lewes, we could see the thick haze below the level of the South Downs, and taste the acridity on our tongues. On the coast itself, it was less noticeable in the sea breeze, but the visibility was much reduced with the Newhaven-Dieppe ferry quickly fading into the murk. The BBC warned of high local pollution (worst near Hastings) and an expert advised against strenuous exercise.
The photo of Cuckmere Haven had to be enhanced as it actually looked all washed out in the haze. The geography is interesting: the Cuckmere River emerges (as a dark horizontal line) through what looks from this viewpoint like a continuous shingle bar across the mouth of the valley. The ‘lagoon’ on the landward side of the shingle is part of a former meander of the river, now cut off as if it were an oxbow lake; the current watercourse is canalized with artificial embankments. In the background are vertical sea-cliffs of chalk, with softer (brown) sands above, eroding at a shallower angle. At the base of the cliffs is a white line of fallen chalk rubble, and a dark horizontal surface, a wave-cut platform of chalk (with dark seaweed). In the foreground is the slope of chalk grassland and (left centre) two wartime concrete pillboxes defending the haven.
Seven Sisters – coastal cliff erosion
Gingerly approaching the cliff edge at a crawl, I took this photo, showing a large cave in the chalk: the waves fracture and undercut the cliff at high tide, causing progressive and often sudden cliff falls. The coastline recedes by about 70cm per year, but this bland average conceals a very different reality: the cliff edge barely changes from one year to another, until in some specially violent winter storm, perhaps three to five metres of chalk grassland and hundreds of thousands of tons of chalk suddenly collapse all at once into a gigantic white heap on the beach. The cave in the photo has created an overhang of more than 10 metres; it will certainly collapse one day in the next few years.
The walk was constantly accompanied by the song-flights of Skylarks, and their darting duels low over the grass. A few Ravens flew about the cliffs, and many Jackdaws; a pair of Carrion Crows mobbed a Raven; a few Magpies brought the number of members of the Crow tribe up to four. Near Birling, Chiffchaffs crept about an orchard, and Blackcaps dived into gorse bushes. Hundreds of Brent Geese flew Eastwards in V-shaped skeins or long lines half a wingspan above the waves. Four or five Little Egrets darted about the Cuckmere Haven lagoon, spearing small fish: a century ago they were hunted to local extinction for their plumes, used for elegant ladies’ hats. The RSPB was founded partly as the “Fin, Fur and Feather League”, a women’s campaign against the cruel and pointless use of animals in fashion that became a major force in bird conservation. In the last thirty years or so they have quietly returned to the south coast and are increasing in numbers.
It’s spring! Well, a Blackcap sang its cheerful spring song to me yesterday, in my garden, how about that, after flying all the way from Africa. Today, a Chiffchaff sang (and briefly appeared) in the nature reserve while I was working down at the frog pond.
And back at home, as I was watering the garden, I saw this Angle Shades moth (Phlogophora meticulosa, a Noctuid) in its final ecdysis, inflating its wings from their crumpled state inside the overwintering pupa. It was on the pipe insulation of the garden tap.

Presumably the moth’s body clock said “It’s spring”. Amazing to watch.
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.
Tiny footprints: Muntjac slots
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.
Well, it’s not every day one wheels a robust two-legged bench about a nature reserve. The team of three however managed to think of a way of balancing the bench on a wheelbarrow using a bit of four-by-two to prop up the legs, and thus poised it turned out to be quite easy to trundle along, carefully dodging trees and bushes along the way.
The holes were just the right depth, so all we had to do was drop in the bench, level it, pour in some water and add rapid-setting post concrete. The bit we had left turned out not to be enough, so after struggling in vain with additional pebbles, we propped it up and those with bicycles went round to the hardware store to fetch some more concrete. Second time proved lucky, the ‘crete set like custard without enough milk added, and very soon we were shovelling the spoil into the holes and stamping it down.
