Priorslee Balancing Lake and The Flash

14.0°C > 18.0°C: Clear with a very few scattered small clouds after 08:00. Light / moderate easterly wind. Very good visibility but hazy at times.

Sunrise: 04:57 BST

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

Priorslee Balancing Lake: 04:50 – 06:10 // 07:15 – 09:40

(123rd visit of the year)

New bird species:
An addition to me 2026 bird list from here: a female (on size) Peregrine Falcon was seen cruising around to the North c.05:50. It never came close enough for a photo. My bird species #87 this year.

Other bird notes:
- the seven Greylag Geese goslings present and correct.
- five Mallard ducklings seen: two almost full-grown birds, easily confusable with ducks; and a trio of sizeable ducklings with their mother
- two drake Tufted Duck were accompanied by a duck today.
- again no juvenile Coots seen. Also the number of adults remains low.
- an adult Black-headed Gull visited briefly at 05:1-
- a lone adult Lesser Black-backed Gull was again on the football field c.05:45. Another visited the lake briefly c.08:35.
- for many weeks the football field has played host to a few gulls and the Starlings. Today there were at least 15 Wood Pigeons feeding there, a species not seen on the grass for many weeks.
- no Lesser Whitethroat heard.
- two Common Whitethroats singing: as yesterday one along the South side but today vocal throughout. *Another display flying over the traditional sire. I presume this means that it did stay and has raised brood #1 and is re-establishing the pair bond for brood #2.
- a Garden Warbler was singing in the tall trees to the South of and then in front of the sailing club HQ. Possibly another was in the south-east area: the combination of a close and very loud Song Thrush and Blackcap along with noise from the M54 prevented confirmation.
- the Mistle Thrush was again singing near the Teece Drive gate, today c.07:30.
- no Starlings were on the football field c.06:00. One was on a roof in Teece Drive c.07:15

Bird(s) noted flying over here:
- 18 Canada Geese: flew West together (and probably among those at The Flash later)
- 2 Herring Gulls
- 3 Lesser Black-backed Gulls
- 3 Wood Pigeons again
- 1 Peregrine
- 4 Jackdaws
- *1 Rook

Counts from the lake area:
- 5 Canada Geese: a pair throughout; a trio arrived and departed
- *3 + 7 (1 brood) Greylag Geese: the third adult throughout
- 2 Mute Swans: the pen amused to be on the nest.
- 21 (17♂) + 5 (2 broods) Mallard
- 3 (2♂) Tufted Duck
- 2 Moorhens
- 14 Coots: only
- 6 Great Crested Grebes
- 1 Black-headed Gull again
- 2 Lesser Black-backed Gulls again
- 1 Grey Heron again

Hirundines etc. noted:
- 4 Swifts: two at c.05:40 and two at 08:50
- 3 Barn Swallows: a single departed to the South: a pair feeding over the West end grass
- 1 House Martin: seen surprisingly over the new estate to the North. I would have doubted there was any suitable nest sites on the new-build housing.

Warblers noted (the number in brackets refers to birds singing):
- 10 (9) Chiffchaffs: many of my "regulars" silent
- 11 (10) Reed Warblers

On the West end street lamp poles around dawn:
staying almost everything free!

Flies:
- 1 plumed midge

Another hazy start to the day though cooler than yesterday. The monsoon rain and hail that affected Shrewsbury yesterday afternoon did not come here.

Three of the seven Greylag Goose goslings. A few wing-feathers are starting to show. So far the cob Mute Swan has shown no interest in these or any Greylag Goose: only Canada Geese. Whether this will change if and when he has cygnets to look after remains to be seen.

The original Common Whitethroat put in an appearance.

A species I have not seen for several day: a Rook. It is disguising its characteristic cone-shaped bill by carrying food. There is no disguising the bare skin at the base of the bill. Other ways to separate from Carrion Crow are more subtle: it is slimmer, the tail longer and the wings often more noticeably "fingered". The call-note is more hoarse.

Can someone explain why when my camera is set to "sports mode" (which it usually is: to "freeze" things in flight) then I can only photograph fairly-Red Admiral butterflies Vanessa atalanta? The colour balance seems all wrong and trying correct with the photo-editor makes things worse.

One of two dreadful photos of moths today. The excuse for this photo of a Silver-ground Carpet Xanthorhoe montanata is that it was c.05:30 and the moth was in deep shade. You get the idea of this commonly seen moth that flushes from the undergrowth.

Buried deep in the long grass and threatening to fly off in to the middle distance if I disturbed it again was my first Silver Y moth Autographa gamma of the year and moth species #24 for me here. At least the silver Y is clear-enough.

An Orange-tailed Mining Bee Andrena haemorrhoa. The "orange tail" is never very extensive and quickly wears / fades.

Most bumblebees were flitting from bramble flower to bramble flower, stopping for seconds, if that. This Early Bumblebee Bombus pratorum posed long-enough to pose.

This is the sawfly Tenthredo mesomela

A Bumblebee Blacklet Cheilosia illustrata. The only member of this genus that is easily recognisable with the white and orange hairs to relieve the all-black of most members. Does not look much like a bumblebee to my eyes.

Smart: a Blotch-winged Hoverfly Leucozona lucorum or, as Obsidentify prefers, Blotch-winged Whitebelt.

My initial thought here was a Tiger Hoverfly Helophilus pendulus but it has only two stripes on the thorax. Obsidentify was 100% sure it is what Steven Falk records as Brush-thighed Stripe-back Parhelophilus versicolor (Marsh Stripeback in Obsidentify-speak). It is a new species for me but...

...with this view of the same insect Obsidentify would only say Parhelophilus sp. A check of Steven Falk's Flickr pages suggests Obsidentify was right first time.

Here with a "thistle" mark on the first body segment is a male Common Blue Damselfly Enallagma cyathigerum.

A not very sharp photo of a male Blue-tailed Damselfly Ischnura elegans. The camera seemed to want to focus either on the head; on the tail; or, as here, on the wings with the other parts less clear.

A Large Red Damselfly Pyrrhosoma nymphula

The only fly I bothered with this morning was this splendid Flesh fly Sarcophaga sp., possibly S. carnaria.

Looking like a small cranefly this is a wood gnat, probably Sylvicola cinctus. Unusual for me to see a wood gnat other than on street lamp poles pre-dawn. A much clearer view and hence a probable specific identity. Genitalia examination is needed to confirm.

A Cucumber Green Orb Spider Araniella sp. either A. cucurbitina or A. opisthographa strangely walking on the hand-rail of the boxing ring on the dam. As previously noted this species spins a web across a leaf and lies upside down waiting for prey to blunder in. It is out of luck here.

Also on the boxing ring was this running crab spider from the Philodromus group. All members of this genus are very variable in markings and cannot be identified from photos.

No visible mean of support for this Long-jawed Orb-web Spider Tetragnatha sp.

Another orchid species today: a Southern Marsh Orchid Dactylorhiza praetermissa.

In the Priorslee Avenue tunnel:

Flies:
- 47(!) midges of several species
- 2 unidentified Limonid cranefly
- 1 owl midge Psychodidae sp. [Drain Fly, Moth Fly or Owl Fly]

There were (at least) 47 midges on the easily-accessed wall of the tunnel. The majority of them were of this species. It looks somewhat like Chironomus plumosus though to my eyes it seems too slim with wing/body ration wrong.

The Flash: 06:15 – 07:10

(120th visit of the year)

Bird notes:
- still five visiting Mute Swans and the presumption of the resident pen on the nest. Three of the visitors made a short flight – all of about 100'!
- a single and growing Canada Goose gosling seen.
- no Greylag Geese again.
- nine juvenile Coots seen from four broods, one of which I had not seen previously.
- at least three Great Crested Grebes seen. A lone bird keeping close to the erstwhile nest site with no suggestion that the site was occupied. Another pair(?) close-by took off together and flew to the top end. These may have been the two birds at the opposite end of the island that I failed to get to grips with.
- a small group of Treecreepers was working the trees near where I photographed a juvenile being fed about a week or go. What I presume was a bird from another family calling from trees around the lower car parks.

Bird(s) noted flying over here:
None

Noted on / around the water:
- 48 + 1 (1 brood) Canada Geese
- no Greylag Geese
- 7 Mute Swans: assuming the pen is on the hidden nest?
- 25 (22♂) Mallard
- 2 Moorhens only
- 27+ 9 (4 broods) Coots: see notes
- 3 Great Crested Grebes: see notes
- 2 Lesser Black-backed Gulls: adults, leaving as I arrived.

Hirundines etc. noted:
None

Warblers noted (the number in brackets refers to birds singing):
- 3 (3) Chiffchaffs
- 4 (4) Blackcaps

Noted around the area:

Butterflies:
- 1 Painted Lady Vanessa cardui

Moths:
- 1 Common Marble Celypha lacunana

"I want my mummy". Since goslings cannot fly they seem to have unusually substantial legs. Mum is a Canada Goose of course.

A surprise at 06:15 in the morning was this Painted Lady butterfly Vanessa cardui. With another seen flitting about at the Balancing Lake and a Silver Y moth there it suggests the recent warm weather from the South has led to a substantial influx of insects from the Continent.

Priorslee Balancing Lake and The Flash

17.0°C > 26.0°C: Clear until a few scattered clouds after 08:30. Calm. Very good visibility but hazy early.

Sunrise: 04:58 BST

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

Not an inspired visit as I try to get rid of a nasty cold..

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

(122nd visit of the year)

Bird notes:
- the seven Greylag Geese goslings present and correct.
- no Mallard ducklings seen but plenty of adults.
- two drake Tufted Duck were new in. The first for nine days.
- no juvenile Coots seen. The number of adults low: perhaps sheltering in the reeds.
- *an adult Black-headed Gull visited c.08:20: an unusual date.
- a lone adult Lesser Black-backed Gull was on the football field c.05:45. *Another visited the lake briefly c.08:10. A small passage overhead early only.
- a Lesser Whitethroat was intermittently singing a brief song from the Ricoh hedge area c.05:00 only. This strongly suggests that it has bred here and is now between broods.
- a Common Whitethroat was singing along the South side c.05:10 only. Perhaps it has found a mate and is busy nesting.
- I could not hear any Garden Warbler.
- with less traffic during the school holiday I was able to hear a Skylark singing from the fields to the East while I was on the dam-top.
- a Mistle Thrush was singing by the Teece Drive gate c.05:00. This early-breeding species has normally finished singing by this date.
- no Starlings were on the football field c.05:50 suggesting the juveniles are strong-enough to fly greater distances to feed. A family party of six flew toward the estate c.09:10

Bird(s) noted flying over here:
- 4 Greylag Geese: one flew East; a trio flew West
- 17 Lesser Black-backed Gulls

- 3 Jackdaws

Counts from the lake area:
- 7 Canada Geese: of these a pair arrived
- 4 + 7 (1 brood) Greylag Geese: the third adult throughout; a fourth visited briefly

- 24 (20♂) Mallard
- 2 (2♂) Tufted Duck
- no Moorhens
- 12 Coots: only
- 5 Great Crested Grebes
- *1 Black-headed Gull
- *2 Lesser Black-backed Gulls
- 1 Grey Heron

Hirundines etc. noted:
- 2 Swifts at c.05:00 only

- 13 (13) Blackcaps only
- 1 (1) Lesser Whitethroat: see notes

On the West end street lamp poles around dawn:
Staying moth free!

Spiders, harvestmen etc.:
- 1 Bridge Orb-web Spider Larinioides sclopetarius
- 1 Long-jawed Orb-web Spider Tetragnatha sp.

A hazy start to the day.

The two drake Tufted Duck. When they look like this it is difficult to imagine that come Autumn it will be hard to tell the sex of many of them.

An adult Black-headed Gull attracted to food.

And flies off with some stale bread courtesy of Paul in the Classic Catering van.

"Any more where that came from?"

Yes. In this photo it is clear that "Black-headed" is wrong on two counts. It has a hood that dark chocolate in colour. Probably too late to change the name...

All gone: sorry.

An adult Lesser Black-backed Gull. Note there are only seven (eight?) primaries visible meaning that the three (or two) inner primaries have been dropped as it starts its post-breeding moult. Hence the "step" in the trailing edge.

A splendid Tree Bumblebee Bombus hypnorum with the orange "pile" on the thorax and white tail.

This may be my first-ever Burdock Blacklet hoverfly Cheilosia impressa. Obsidentify's name for the species, Yellow-winged Blacklet, may seem appropriate but females (and this is a female) of the common Buttercup Blacklet C. albitarsus also have yellow at the base of their wings. As their scientific name suggests these should show pale on the legs and these look all dark. It is not on a buttercup but Cow Parsley Anthriscus sylvestris and there is a Parsley Blacklet C. pagana... A difficult group....

..and neither Obsidentify or Google Lens would be drawn to identify thus beyond Cheilosia sp.

A freshly-emerged Common Blue Damselfly Enallagma cyathigerum. These develop as larvae in the water and when ready to emerge the larvae climb up anything suitable to enable them to emerge and dry out before taking to the wing. At this stage they are known as tenerals. The colour develops over a few days. This one was on the boxing ring on the dam.

A Common (or Red-headed) Cardinal Beetle Pyrochroa serraticornis. I wonder how it got that name?!

Beginning to appear are the first Common Spotted-orchids Dactylorhiza fuchsii of the year.

Just opened are a few Blue Flag Iris Iris versicolor. I read that this species is not native to the UK and that all instances are as a result of garden escapes / deliberate planting.

Spiders seem to have been visiting this Common Poppy Papaver rhoeas. The seeds of this species are almost indestructible and can stay in the ground for many years until conditions are suitable. As a result they often emerge after ground has been worked.

------------------------------------------------------------------------------------------------------

In the Priorslee Avenue tunnel:

Flies:
- 33(!) midges of several species
- *1 cranefly Limnophila schranki [Broad-winged Mottled Longneck]
- *1 cranefly Tipula vittata
- 1 otherwise unidentified Limonid cranefly
- 1 owl midge Psychodidae sp. [Drain Fly, Moth Fly or Owl Fly]

Spiders, harvestmen etc.:
- *1 possible Snake-back Spider Segestria senoculata

This seems to be the cranefly Limnophila schranki also known as Broad-winged Mottled Longneck. It is a new species for me.

The cranefly Tipula vittata. Apart from the distinctive wing pattern it is characterised by a pale line down the centre of the abdomen. Or dark lines down the sides of the abdomen, depending on your perspective.

This seems to resemble the Snake-back Spider Segestria senoculata.

(Ed Wilson)

------------------------------------------------------------------------------------------------------

The Flash: 06:00 – 07:00

(119th visit of the year)

Bird notes:
- still five visiting Mute Swans and the presumption of the resident pen on the nest. The cob seems resigned to the presence of the visitors and made no attempt to intimidate them.
- no Canada Goose goslings seen.
- no Greylag Geese.
- *again only two juvenile Coots seen. None of the two broods of four alongside Derwent Drive was seen. Perhaps keeping out of the sun?
- the single adult Great Crested Grebes seen again.
- one or two Great Spotted Woodpeckers seen ferrying to and from the island. Not sure whether they were carrying food there or faecal sacs away.

Bird(s) noted flying over here:
None

Noted on / around the water:
- 59 Canada Geese: of these 23 were seen to depart
- no Greylag Geese
- 7 Mute Swans: assuming the pen is on the hidden nest?
- 22 (20♂) Mallard: where were many of the ducks?
- 4 Moorhens
- *20 + 2 (1 broods) Coots: see notes
- 1 Great Crested Grebe

Hirundines etc. noted:
None

Warblers noted (the number in brackets refers to birds singing):
- 4 (4) Chiffchaffs
- 3 (3) Blackcaps

Noted around the area:

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

The only juvenile Coots today seemed to want to snuggle up even in the warm weather.

Another sequence of something I have not seen previously. A pair (one hopes!) of mating Song Thrushes.

He seems pleased with himself. Sufficiently so...

...to repeat the process.

Almost in danger of falling off. She seems to be standing in tippy-toes.

Definitely unstable.

Oops.

Something to celebrate? Throughout I heard no song or call from these two.

Third time lucky? She has feet firmly planted on the ground this time.

"Thank you ma'am. I'll be off now".
