Priorslee Lake and The Flash

14.0°C > 17.0°C: Variable amount of low cloud below barely broken medium overcast. Early light rain. Moderate easterly breeze, fresh at times. Good visibility.

Sunrise: 06:47 BST

+ = my first sighting of this species at this site this year.
++ = new species for me at this site.
* = a species photographed today

Highlights today were:
- a duck Shoveler again at The Flash (assuming it ever went away and didn't just hide among the geese)
- two Tawny Owls calling from the Ricoh grounds
- my first Siskin of Autumn over the lake

Priorslee Balancing Lake: 05:15 – 09:15

(190th visit of the year)

Bird notes:
- Yesterday's drake Wigeon not located.
- 62 Black-headed Gulls arrived at the lake after 06:25. How many of these were among the c.230 on the football field at c.06:45 remains unclear.
- I remain confused about Tawny Owl calls. Some sources suggest that both sexes can make both the screech and hoot. I heard both this morning and the calls were close together. They must have been deafening each other if there were two birds involved.
- At least 25 Pied Wagtails were on the football field c.09:00.

The best I could do with the poor sunrise.

Yes well: a first winter gull. The pale on the inner webs of the inner primaries suggests it is a Herring Gull. However the contrast is less than I would expect. I do wonder about it being a Yellow-legged Gull though I would expect that to show a much whiter head than shown here. I have included it in the log as a Herring Gull.

Always easier when you can spend time looking in detail. All three are first winter gulls, the paler bird on the left is a Herring Gull; the other two are Lesser Black-backed Gulls.

The epitome of scruffy. A second year Lesser Black-backed Gull with very battered plumage.

Not much better here.

Almost respectable.

A Grey Wagtail.

A Square-spot Rustic moth (Xestia xanthographa). I am not having much luck finding a specimen with a very obvious 'square spot'.

"What red eyes you have". Obsidentify suggested this might be a species of Lance Fly. Research on the internet fails to illuminate that suggestion.

This green-bodied insect is a male plumed midge (Microtendipes pedellus) I found on the wall of the sailing club HQ.

This fly was, unusually, on the wall of the sailing club HQ in the dark. It is well-marked but I can't get and identity for it.

Another unidentified fly.

The only cranefly I (could be bothered to) photograph was this female European Cranefly (Tipula paludosa).

A Clubiona sp. spider on a street lamp pole.

A Bridge Orb-web Spider (Larinioides sclopetarius) on the wall of the sailing club HQ.

A Nursery Web Spider (Pisaura mirabilis). As shown here these often rest with their front two pairs of legs held together.

I think this is a Strawberry Snail (Trochulus striolatus). It is much larger than yesterday's Wrinkled Snail (Candidula intersecta).

The Shaggy Inkcap or Lawyer's Wig fungus (Coprinus comatus) continue to deliquesce.

The Flash: 09:20 – 10:20

Noted elsewhere around The Flash:

Bees / wasps etc.:
- Honey Bee (Apis mellifera)
- Buff-tailed Bumblebee (Bombus terrestris)
- Common Wasp (Paravespula vulgaris)

Hoverflies:
- *Platycheirus sp., probably Grey-spotted Boxer (P. albimanus) [also known as Grey-spotted Sedgesitter]
- *Syrphus sp. (S. ribesii / S. vitripennis)

Other flies:
- *Phaonia tuguriorum (a species in the family Muscidae or House flies)
- *at least three other species of small fly

Beetles:
- Alder Leaf Beetle (Agelastica alni); adults

Bugs:
- *Common Green Shieldbug (Palomena prasina)

Spiders:
- Garden Spider (Araneus diadematus)

A very distinctive hybrid goose that I have not seen recently, if at all. There seems to be some Canada and a lot of Greylag Goose genes However it is somewhat larger than either species so...

A very small hoverfly. One of the Platycheirus sp., probably a Grey-spotted Boxer (P. albimanus).

Another view. It is a female with the eyes well separated. It is feeding on the small flowers of what might be Hybrid Coralberry (Symphoricarpos x chenualtii).

This is a hoverfly from the species pair Syrphus sp. (S. ribesii / S. vitripennis). Obsidentify suggests a Humming Syrphus (Syrphus ribesii) though I cannot see why it makes that identification.

A fly I have identified (well Obsidentify did and I confirmed it). A Phaonia tuguriorum (a fly species in the family Muscidae (House flies)).

An unknown species of fly.

An instar of a Common Green Shieldbug (Palomena prasina).

And an adult tries to hide.

Noted in the Priorslee Avenue tunnel:

Moths:
- *2 Silver Y (Autographa gamma)

Other things:
- 1 cranefly Tipula confusa
- *1 male cranefly Tipula lateralis
- 14 White-legged Snake Millipedes (Tachypodoiulus niger)
- *1 Walnut Orb Weaver spider (Nuctenea umbratica)
- several other, unidentified, spiders
- *1 female Leiobunum blackwalli harvestman

*An update. Back on 28 August I noted a micro moth on railings beside a street lamp pole between the lake and The Flash. I could not identify it and neither could, at the time, the Shropshire recorder. He has now let me know that it was an Italian Tubic (Metalampra italica). This species was first recorded in the UK as recently as 2003 in Devon. Once thought to be confined to Italy (hence its name) it has now been recorded widely in Europe. Originally assumed to be a migrant species it is very likely to be breeding in the UK.

A Silver Y moth (Autographa gamma).

And the other one.

A male cranefly Tipula lateralis.

You WILL like spiders! This is a Walnut Orb Weaver spider (Nuctenea umbratica).

A female Leiobunum blackwalli harvestman. The dark saddle widens posteriorly and the eyes have a white ring.

And

Here is the recently identified Italian Tubic moth (Metalampra italica) from 28 August.
