Priorslee Balancing Lake and The Flash

11.0°C > 15.0°C: Early cloud cleared by 06:30. Fine for a while. Mostly cloudy again by 08:00, lowering later. Light and variable breeze becoming moderate south-westerly. Excellent visibility.

Sunrise: 04:51 BST

Out of time again to get the photos edited and annotated. Watch this space....
! = a new species for me here this year
!! = a new species for me in Shropshire

Priorslee Balancing Lake: 04:55 – 06:05 // 07:15 – 09:25

(142nd visit of the year)

New Bird Species
Highlight today was a Yellow Wagtail that flew on to the dam-top at 08:30, staying less than 30 seconds. My first record here this year on an atypical date: normally I see, or more often only hear, bird passing on Spring passage in April. Bird species #96 for me here this year.

Also worth special note are the first returning waders of the year: two Common Sandpipers were present at 05:30 with at least one, presumably of these, still present at 09:00. [26 June in 2023 for the first returning bird]

Other bird notes:
- the Mallard brood, assuming it is the same brood, now down to two ducklings.
- a Garden Warbler still singing from the south-west copse.
- six Pied Wagtails were on the football field at 09:15. At least two were adult males so not just a family party.

The two Common Sandpipers present at 05:30.

The bird present at 09:00. One of the same? The feathering indicates this is a breeding condition adult.

A smart bird.

Always a delight to see. A Clouded Border moth Lomaspilis marginata.

An all-wrapped-up large moth on one of the street lamp poles that I have been unable to identify. Note the very feathered antennae. The white spot is eye-shine from the camera flash.

This seems to be a female parasite wasp from the Campopleginae family. I read there are 350 species in the UK! They are all small – note the size compared with the grass seed-head it is resting on.

Not many hoverflies on the wing this morning. This is a Bumblebee Blacklet Cheilosia illustrata.

And a female Chequered Hoverfly Melanostoma scalare.

This is one of the boxer group of hoverflies of the Platycheirus genus. They are difficult to separate unless the abdomen pattern is visible.

A Blue-tailed Damselfly Ischnura elegans with the black-and-white pterostigma on the leading edge of the wing.

A Common Orange Legionnaire Beris vallata. One of these small flies that is relatively easy to identify.

A Black Snipefly Chrysopilus cristatus from an interesting angle. I needed to double-check this species as I have yet to record the most common of the snipeflies this year, the Small Fleck-winged Snipefly Rhagio lineola. Had I been misidentifying them? Nope: this is a Black Snipefly.

This dance fly from the Hybos family seems to have even larger swollen hind tibia than usual.

Another chance to see a male Semaphore fly Poecilobothrus nobilitatus.

I am not at all confident about the identity of this unusual-looking fly. It may be the blackfly Simulium angustitarse. The blackfly family of here is distinct from the "blackflies" of the Aphid family.

A Common Froghopper Philaenus spumarius. This species is very variable in markings.

 This is a flower bug but too battered and faded to get an identity.

This is the larva of a Harlequin Ladybird Harmonia axyridis.

 Just one of these False Blister Beetles Oedemera lurida or O. virescens found today.

This Leiobunum species of harvestman was too far up the street lamp pole to see the markings clearly-enough to make a positive ID.

A Creeping Thistle Cirsium arvense. A species I have not previously identified from here.

Nothing seen!

The Flash: 06:10 – 07:10

(145th visit of the year)

Bird notes:
- just two Mute Swans seen. One at the top end and presumably the erstwhile third white bird. And one presumed resident adult sitting among the Coots on the edge of the island. The other resident and the cygnets presumed to be inside the island.
- even more Coots with 51 counted standing together along the East side of the island. They were so jammed together that an accurate count would have required a telescope. I did my best counting the white shields!
- the first returning Black-headed Gulls overhead and then later one on the edge of the island. The same date as in 2023.

Bird(s) noted flying over here:
- 2 Black-headed Gulls
- 1 Lesser Black-backed Gull
- 3 Jackdaws

Hirundines etc. noted:
- 6 Swifts
- 1 House Martin

Warblers noted (the figure in brackets relates to birds heard singing):
- 6 (6) Chiffchaffs
- 3 (3) Blackcaps
'nominal' warbler:
- 2 (2) Goldcrests

Noted on / around the water:
- 228 Canada Geese
- 66 Greylag Geese
- 1 Canada x Greylag Goose
- 2 Mute Swan
- 37 Mallard: no ducklings seen
- 8 (6♂) Tufted Duck: of these four drakes flew off together
- 7 + 5 (3 broods) Moorhens
- *61 Coots
- 2 Great Crested Grebes
- 1 Black-headed Gull

Noted elsewhere around The Flash:

Moths:
- 1 Tawny Grey Eudonia lacustrata
- *1 Riband Wave Idaea aversata form remutata

Flies:
- *1 micro-caddisfly, just perhaps Agraylea multipunctata

Not easy to see what this is. It is an adult Coot because it has a full white shield. Look toward the tail and see how the wings, with the wing feathers regrowing, do not cover the flanks. I have never noted this on a Coot previously. Perhaps this explains the congregation of birds on the island: they all flightless and the usual testosterone is not present during the moult.

A Riband Wave moth Idaea aversata of the form remutata a long way up a street lamp pole in squirrel alley.

I am doing well with unidentified or partially identified creatures today. This is one of the micro-caddisflies, just perhaps Agraylea multipunctata.
