Willow Emerald Damselfly Eggs in Willow Twig

Willow Emerald Damselfly Eggs in Willow Twig. The female cuts a slit in the bark for each egg. The cuts have healed up (by now, November) leaving a bump around each egg.
Willow Emerald Damselfly (photographed earlier this year). The species is very new to Britain, having arrived last year or not long before that; and this year is the first time we’ve seen them at Gunnersbury Triangle, so it’s very exciting to see the unique egg-laying traces!

(Prob. Southern) Hawker Dragonfly Nymphs, Pond Snails. We also saw plenty of Ramshorn Snails, a flatworm, a leech, small diving beetles, damselfly nymphs, water fleas, Greater Water Boatmen (Backswimmers), young newts (with 4 legs and gills) and more.

Moths at Gunnersbury Triangle

Angle Shades, named for the dark angled markings

Netty had a successful night with the moth trap.

Pyrausta purpuralis, a small but beautiful “micro” moth. And yes, it’s name means the purple one in Latin
Heart and Dart, one of 3 trapped (and released after ID). The name refers to the black markings
Rustic. We scratched our heads at its similarity to Uncertain (hah!) but it does seem to be the paler and less distinct species all the same.

 

Gunnersbury Triangle Damselflies Egg-Laying Like There’s No Tomorrow!

Shimmer and sparkle: many pairs of ovipositing Azure Damselflies – seven seen here, there were at least fifteen pairs, not to mention …#
Large Red Damselfly (there were several pairs)
Male Bluetail Damselfly on a reed leaf: there were two males tussling, but no female as yet
Yellow and Orange ‘escaped’ Goldfish in GT pond. Perhaps people think ‘setting them free’ when moving house will be a good thing, but they devastate native pond life

Nightingales at Northward Hill

Northward Hill, looking over oakwood, scrub, grazing marshes, and river

Well there are some things one just has to do, even if it means braving the traffic. Nightingales, once common all over the south of England, can now only be heard in a few special places, and Northward Hill is one of them. There are some others in the southeast, like Lodge Hill, and guess what, they want to build houses all over it. Better go and enjoy the birdsong while it lasts.

A very shy Wall Brown, now a mainly coastal butterfly, the first I’ve seen for years

I was greeted by the song of blackbird, chaffinch, robin, song thrush, and wren as I walked in. A few ‘whites’ – large white, orange tip, green-veined white – skittered about as I reached the attractively rough scrub of hawthorn in full May blossom, blackthorn, wild pear, wild plum, and wild cherry, topped by the occasional whitethroat singing away scratchily.

Into the woods, with a handsome old cherry orchard on the right. Some of the oaks were straight out of Lord of the Rings, splendidly gnarled, knobbly, with massive trunks and holes to hide a good few goblins in.

Nightingale country: a fine old Oak. It looks to have been pollarded at about 12 feet up some centuries ago, so it was probably cut to that height while smaller wood was coppiced all around it.

And yes, sure enough, a nightingale obliged by singing its hesitant but amazingly rich and varied song from the thick cover. A little further, another; and a cuckoo kindly sang its unmistakable song from an oak almost in front of me, then with a ‘gok’ call flew, sparrowhawk-like, from the tree, a special sight.

Down to the hide overlooking the pool in the top photo; I wasn’t expecting more than a coot and maybe a mallard, but there were breeding lapwings chasing off the crows; breeding oystercatchers, and an avocet sitting with them; and a couple of solitary little egrets, stalking and stabbing at small fish or frogs. A redshank gave its wild teuk-teuk-teuk call and flashed its wingbar briefly.

Little Egret Stalking

Overhead a few swallows flitted about, and three swifts raced over the marsh.

The Hoo Peninsula is still a wild, spacious, lonely place, even with the swelling villages. You can see the Shard and Canary Wharf in the distance (some 30 miles); the river with its cranes and giant ships is ever-present; but the North Kent Marshes are special, as is Northward Hill with its fine old woods, still unspoilt for birds. Go and see it while you can.

 

 

Spring Migrants at Thursley Common

Eriophorum angustifolium, Bog Cotton, a plant of wild, wet and rugged places

A bright, breezy, and much cooler day (16 C, not 29 any more) was just perfect for a visit to Thursley. Perhaps many of the dragonflies decided not to fly: I saw one Common Darter and (I think) one Brown Hawker, and nothing else, so anyone who went along hoping to see the Hobbies hawking for dragonflies by the dozen will have had a wasted trip (and indeed I saw several extravagantly camouflaged types with gigantic telescopes standing about looking very bored).

But everything else was in full swing. A Cuckoo called from the pinewoods. A Curlew gave its marvellously wild, bubbling call from the open marsh. A Dartford Warbler gave me the best view ever of its rufous belly and long tail, as it sat low in a scrubby Birch, giving its rasping anxiety call repeatedly. I enjoyed the view through binoculars. By the time I remembered to take a photo it was half-hidden again.

A Stonechat gave its scratchy call from a small Birch, then hopped up to some Pine trees (so, a distant shot).

A few Chiffchaffs called from the woods; plenty of Whitethroats sang from the regenerating Birches that are encroaching on to the heath. A Green Woodpecker gave its fine laughing call.

Birches regenerating on to heath below Pines

So I heard three warblers today to add to the four yesterday, so seven singing warblers in 24 hours, a little bit special.

The lichen flora on the heath was quite beautiful, with Usnea beard lichen, leafy Parmelia, bristly Ramalina (all on old Heather), and elegant Cladonia potscourer, cup, and stalk lichens (three species).

Miniature elegance: Cladonia cf fimbriata, cup lichen

A Linnet sang from the top of a Birch. Goldfinches twittered and flitted about.

And on the path out, a Hobby leapt from a tree right in front of me, where it had been sitting watching the bog pools,  waiting for dragonflies to come out and display themselves. It flew round and up, then circled, soaring, away to the south. Perhaps it was the one the twitchers had been waiting to see flying all morning.

Hedgehog Day!

Mass Hedgehog Production. Cocoa or Plain (with a pinch of cinnamon). Someone should teach that Biscuitier that hedgehogs have very small eyes.

Gazebos Rain Tea Hedgehogs. On the ground is not Snakes and Ladders, but rather Hedgehogs and Strimmers. People came through all day, with a brief lull at lunchtime, and an amazing number of hedgehog houses (real, out of corrugated plastic) and hedgehog models and drawings were made.

LWT Hedge-Laying Course with Clive Leeke at GT

Netty delighted to find a Tawny Owl feather in the reserve, for the first time

The hedge before we started: tall, leggy, and apparently never cut or laid before
Clive demonstrating how to cut a pleacher, a Hawthorn stem that you can then lay to form a barrier. Somehow it looked quite easy when he did it.
… and down goes the pleacher, that’s all you have to do.
Well we managed it somehow, our first pleached Hawthorn (a complex job with a lot of stems to lay)
Clive Leeke showing us how to sharpen a stake with a few swift axe-blows
Hedge-Staker extraordinaire. The idea is to space them a cubit apart, in a straight line, trapping every pleached stem. The binders then retain the stakes. Well, that’s the theory…

Charming Wooden Animal Trail at Gunnersbury Triangle

Wooden Animal Trail Camouflaged Smooth Newt

Netty found some dusty but very well-made wooden animals, complete with attachment rings, evidently designed for use on a Nature Trail. She repainted all of them and we hung them around the reserve. The camouflaged animals – the newt and the frog – seemed to ‘work’ the best. We hope the children will have fun going around with their parents to find them. One or two may be quite difficult!

It wasn’t all wooden animals. As it happens, we saw some of the real things, November or not.

Wooden Animal Trail Dragonfly

[Spoiler alert!] We went down to the pond to affix the Dragonfly, and spotted a small limp orange shape floating apparently lifeless at the surface…

Rescuing a drowning newt. We put it in one of the Anthill Meadow refugia (under a carpet mat), it seemed to be fine.

Then we started mowing the Ramp Meadow with its remarkably fine stand of Evening Primroses …

… and found a real frog, escaping the scythes and boots.
