Priorslee Balancing Lake and The Flash

16.0°C > 19.0°C: A few breaks in low cloud early. Then a short spell of light drizzle c.06:30 after which cloud gradually lifted and broke with some sun after c.09:00. Increasing south-westerly breeze. Very good visibility except during drizzle.

Sunrise: 06:23 BST

* = a species photographed today
! = a first sighting of the species this year
$ = a new species for me in this area

Priorslee Balancing Lake: 04:50 – 09:15

(199th visit of the year)

Bird notes:
- for some while I could only see one Mute Swan. The other "appeared" later from?
- eight Tufted Duck noted: at least three drakes.
- the first 15 Black-headed Gulls had arrived by 05:45. c.105 were present by 06:00 when a large group of at least 350 arrived from the south-east (historically early arrivals tended to be from the West).
- 18 Lesser Black-backed Gulls visited early. None later.
- at c.06:45 I checked the football field finding c.350 Black-headed Gulls, an *adult Herring Gull and single *second year and *adult Lesser Black-backed Gulls. Strangely no Wood Pigeons were on the grass.
- a Little Egret was flying around the East end at 06:15. I did not see it arrive or depart.
- no Swifts were noted.
- with much low cloud still c.07:30 at least 50 Barn Swallows were low over the water. As the cloud lifted and the wind increased many of these were flying around over the dam as insects were blown up from the lake. It was hard to tell whether birds were moving on or just away and back again [I noted that the resident swallows had departed from Sleap Airfield since Monday]
- twelve House Martins were high overhead the football field at 06:45. A few minutes later there were more than 30 swirling around.
- a Willow Warblers noted in song.
- three of at least 14 Chiffchaffs were noted singing.

Through a gap in the cloud this is the best I could manage of the almost half-moon.

Not a sunrise to get out of bed for.

In the foreground a hybrid Canada x Greylag Goose. There have been a number of these around over the years, subtly different in markings. Last Winter they were strangely absent and then one turned up at The Flash on 31 May for just one day as the geese were beginning to assemble ahead of their annual wing-moult.

Among the c.350 Black-headed Gulls on the football field was this adult Herring Gull [I know it is not "crisp" but it was only c.06:40].

Also this second year Lesser Black-backed Gull (with a first-winter Black-headed Gull showing off behind it).

And an adult Lesser Black-backed Gull.

A warbler with an obvious supercilium that I thought at the time might be a Willow Warbler. Not so: the dark bill and especially the all-dark legs identify it as a Chiffchaff.

This may, or may not, be the same bird – there were a number of Chiffchaffs travelling with a party of...

...Long-tailed Tits. I am sure AI would be able to erase the annoying out of focus twig in the foreground.

This tiny moth on an Ivy leaf is a Common Nettle-tap Anthophila fabriciana. Last year I recorded over 40 of this species. This is only my sixth this year.

 "Come in number three"; a Square-spot Rustic moth Xestia xanthographa.

How to stop Common Wasps Vespula vulgaris annoying you – when you are a European Hornet Vespa crabro!

Take that!!

Distinctively marked: a Greenhouse Slug Ambigolimax valentianus.

A Large House Spider-type from the Eratigena group running away.

A delicate fungus that probably will not last the day before it collapses. It is one of the Parasola species that are almost impossible to specifically identify from photos even if you are an expert.

In the Priorslee Avenue tunnel:

An early visit again c.05:00

Moths:
- 1 *Flounced Rustic Luperina testacea
- 1 Square-spot Rustic Xestia xanthographa

A dark specimen of a Flounced Rustic moth Luperina testacea. I separate this species from other moths with this shape at rest by the dark area where the inner edges of the wings join. My 42nd species of moth found in the tunnel this year.

- 1 Lesser Black-backed Gull

Noted on / around the water:

- 1 *Comma Polygonia c-album

Moths:
none

Bees, wasps etc.:
- >5 Honey Bee Apis mellifera
- 3 Common Wasps Vespula vulgaris

Hoverflies:
- 1 *Compost Hoverfly Syritta pipiens [Common Compost Fly; Thick-legged Hoverfly]

True flies:
- greenbottle Lucilia sp.
very few other unidentified flies seen.

Bugs:
- 1 ! *Hairy Shieldbug Dolycoris baccarum [Sloe Bug]
- 1 *Common Green Shieldbug Palomena prasina: instar

Beetles:
- 1 7 Spot Ladybird Coccinella 7-punctata

The immature Great Crested Grebe still with head stripes. Possibly from one of the early broods at the Balancing Lake where some have departed.

Very smart: a Comma butterfly Polygonia c-album.

This is a Compost Hoverfly Syritta pipiens. One of this species' other names of Thick-legged Hoverfly is pertinent here though there are other hoverflies to which that epithet could equally well apply. My logs suggest that I have not previously seen this species around The Flash.

This is a Hairy Shieldbug Dolycoris baccarum also known as a Sloe Bug. The photo is somewhat over-blown as I had to use full zoom to avoid the camera focussing on vegetation around the insect. My first of the year.

An early instar of a Common Green Shieldbug Palomena prasina.
