A walk from Stone
Mum and Dad and I went up to Stone, on the South side of the River Blackwater, up in the wilds of Essex. I spent a few hours strolling the sea wall, strolling and wildlife spotting in the glorious sunshine, as my Dad played with boats. Birds were surprisingly few and far between, with, in what must be a first for a walk by the River Blackwater, no waders spotted, though Common Terns flew by with characteristic grace. However there was a veritable feast of butterflies. Mumsie spotted a Marbled White, and as I walked I counted many of these big Satyrids, and a pair danced among the parched grass. Their dance, presumably a courtship display, was rudely but accidentally interrupted by a Small White, causing one of the Marbled Whites to abandon the dance, and the other, if one can imagine a butterfly angry, chased the intruder furiously for 50 metres or more along the sea wall, until they were out of sight.

Butterfly highlight was a pair of Clouded Yellows, which flew up and down the sea wall at speed, full of the sun's energy, and then ascended, twisting and turning around each other, into the blue heavens. Clouded Yellows are a scarce, accidental migrant from continental Europe, some years irrupting into Southern England across the channel. Sadly they are continuously brooded, and seem unable to survive a British winter, and little correlation is seen between their numbers one year to the next.

A curious, large black bumblebee was not identified, and I think subsequent investigation led us to the conclusion it was probably a melanistic example of one of the Cuckoo bee species.

A single small copper, and a number of little orange Small Skippers flew, but Gatekeepers were by far the commonest butterfly, indeed I maxed out the counter on the iRecord butterfly app, which settled, curiously, on '101+.' A beautiful Great Crested Grebe fished on the shimmering water, and Dad enjoyed the song of a Wren from one of the sailing club chalets.

Canvey Wick, 21st July 2020
Mumsie and I found our intended destination, the excellent RSPB reserve at West Canvey, was still closed as a result of the coronavirus, so we headed over to the Buglife/Land Trust/RSPB reserve at Canvey Wick, a former industrial site, its concrete now home to some rare and unique invertebrates, including Shrill Carder Bees, one of the country's rarest bees, and Brown Banded Carder Bees.
The summer sun was high, and bright, and the air was calm, the weather glorious.
Sadly, during lockdown the dog walkers had been doing their worst, and the path up from the car park was rather unpleasant, but entering the reserve 'proper' we found a riot of floral colour, from tiny alpines, to large and unfamiliar blooms, scarcities and garden escapes leaf by petal, no doubt. They rather made me wish I was I was a better botanist.

From a high wooden platform stretching over the Thames, we saw the unmistakable shape of a Whimbrel, probably a returning migrant, probing about in the mud with sharply downcurved bill, while Godwits flocked in the distance. A Little Egret flew out from under us, brilliant white in the sunshine. There were plenty of Carder Bees of various descriptions about, and beautiful little solitary bees. Whitethroats sang, and we saw many fledglings of this charming warbler. Mumsie found a Wall Butterfly, and a stunning Holly Blue, which invited photography.
