Priorslee Balancing Lake and The Flash

3.0°C > 8.0°C: Clear and hazy again early. Thin high cloud spreading from the West. Light north-westerly breeze. Moderate / good visibility.

Sunrise: 06:15 GMT

First time on "summer schedule": once around the Balancing Lake; up to, around and back from The Flash; and then around the lake again. When I can manage it without getting caught up in the school traffic!

* = a species photographed today
$ = a new species for me in this area

Priorslee Balancing Lake: 05:50 – 06:50 // 07:55 – 09:25

(66th visit of the year)

New bird species:
Three additions to my 2026 bird list for here: in sighting order:
- a Blackcap was seen in spluttering song in the north-east area c.07:30. What I presume was the same bird was heard singing properly along the North side c.08:15. The same date as my first here in 2025.
- several House Sparrows had made it from the estate on to my (self-imposed) recording area in the bushes between Teece Drive and the football field.
- a Green Woodpecker was heard calling from the North side c.08:30. I could not locate the bird. Two days earlier than the last one I heard – at The Flash in 2025.
My bird species total here moves on to #70.

Other bird notes:
- a first-winter Black-headed Gull dropped in briefly: the only gull seen here today.
- yesterday's pair of Shoveler not seen.
- a Reed Bunting was calling along the South side; one was singing along the North side.

Bird(s) noted flying over here:
- 1 Greylag Goose: flew West
- 2 Greylag Geese: pair flew East
- 1 Stock Dove
- 31 Wood Pigeons
- 1 Jackdaw
that's all

Counts from the lake area:
- 12 Canada Geese
- 1 Greylag Goose: departed
- 2 Mute Swans
- 11 (8♂) Mallard
- 18 (14♂) Tufted Duck
- 8 Moorhens again
- 27 Coots
- 4 Great Crested Grebes

- 1 (1) Blackcap

Noted on the West end street lamp poles pre-dawn:
much dew on all the poles.

Flies:
- *male and female plumed midges Chironomus plumosus

Spiders, harvestmen etc.:
- *1 Long-jawed Orb-web Spider Tetragnatha sp.

Noted later:

Bees, wasps etc.:
- >3 Buff-tailed Bumblebees Bombus terrestris

Spiders, harvestmen etc.:
- *1 money spider

Slightly better than the forecast fog and / or low cloud.

Taken later. Some of the early aircraft arriving from the USA have left some partial contrails in the sky.

This photo seems to capture both a male and a female plumed midge Chironomus plumosus: the male on the left with plumed antennae; the female on the right with a shorter, stouter abdomen and simple antennae.

It seems a midge has fallen victim to a money spider. Whether the spider happened upon the dead midge (no web is apparent) or whether it managed to catch and subdue it is unclear. Spiders do tackle prey items much larger than themselves. It almost looks as if the spider has more than eight legs. I assume the "extras" are its palps either injecting venom in to or sucking blood from the midge.

My photo of this Long-jawed Orb-web Spider Tetragnatha sp. reveals that there was one of the small globular springtails present as well.

The Flash: 06:55 – 07:50

(63rd visit of the year)

Bird notes:
- only one Great Crested Grebe noted: asleep near the putative nest site.
- a Blackcap seen and heard singing: perhaps the first true migrant here this year.
- no Siskins seen or heard

Bird(s) noted flying over here:
- *2 Cormorants: together

Noted on / around the water:
- 19 Canada Geese: probably more inside the island
- 2 Greylag Geese
- 2 Mute Swans
- 21 (17♂) Mallard

- *27 Coots
- *1 Great Crested Grebe
- *1 Black-headed Gull: adult
- *2 Lesser Black-backed Gulls: adults, departed

Warblers noted (the number in brackets refers to birds singing):
- 4 (4) Chiffchaffs
- *1 (1) Blackcap

Of note around the area:

Bees, wasps etc.:
- 3 Buff-tailed Bumblebees Bombus terrestris

Ms. Mallard does not look impressed with either of her suitors. [PS: it is the roof that slopes – honest!]

A Great Crested Grebe (pretending to be?) asleep near a putative nest site and ignoring the passing Coot.

An adult Black-headed Gull still to moult out a few white feathers around the base of its bill before it is in full breeding plumage.

Two smart adult Lesser Black-backed Gulls.

One of them leaving. This species has bright yellow legs in the breeding season. What we see here are the feet which are pink: the legs are tucked up.

Two Cormorants flying over, both adults in full breeding plumage, each with a large white thigh patch and extensive white throat patch and neck plumes.

This female Blackbird seems to be trying to decipher the patterns on the rock.

Give up and look for food instead.

It is just about possible to make this out as a male Blackcap.
