Priorslee Balancing Lake and The Flash

10.0°C > 13.0°C: Amazing: both the almost full moon and the sun seen! Some mainly high cloud. Light southerly wind. Very good visibility.

Sunrise: 07:40 BST

* = a species photographed today.

Priorslee Balancing Lake: 05:55 – 09:20

(220th visit of the year)

Bird notes:
- generally there were fewer gulls despite / because of the clearer conditions.
- I have no idea why there were so few Rooks.
- after very few recent Reed Bunting records there was a small roost seen dispersing from their traditional West end site.

Counts of birds noted flying over:
- 9 (?♂) Tufted Duck: five flew West; four flew East and presumed same flew West a few minutes later
- 1 Stock Dove
- 85 Wood Pigeons: of these 54 in just three migrant flocks
- 38 Lesser Black-backed Gulls
- 3 Cormorants: single and duo
- 1 Sparrowhawk
- 331 Jackdaws
- 16 Rooks
- 1 Skylark
- 55 Redwings: of these 52 in five groups; at least three heard flying over pre-dawn
- 1 Pied Wagtail

Birds seen leaving roost around the lake:
- 3 Reed Buntings

Warblers noted (the figure in brackets relates to birds heard singing):
- 1 (1) Cetti's Warbler

Counts from the lake area:
- 10 Canada Goose: of these four departed
- 19 Mute Swans
- 8 (5♂) Mallard
- 8 (3♂+) Tufted Duck

Noted on the street lamps poles pre-dawn:

- 1 wood gnat Sylvicola sp.
- *1 unidentified cranefly

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

Sailing Club
Around the outside of the Telford Sailing Club HQ pre-dawn:

Flies:
- *13 craneflies

Slugs, snails etc.:
- *2 unidentified slugs
- 1 White-lipped Snail Cepaea hortensis
- *2 Girdled Snails Hygromia cinctella

Spiders, harvestmen etc.
- 17 spiders of several species

Noted later:
- Shaggy Inkcap or Lawyer's Wig Coprinus comatus: one more has appeared

The setting full moon according to my phone camera. Note that at this time the visiting Mute Swans escape being penned in to the south-east corner.

Look! A sunrise! This in my 'big' camera.

And this from my camera phone.

A spectacular cloud as part of the sunrise.

Later the high cloud produced this dramatic sky.

Yesterday's deluge produced the usual mud-stained water from several of the sluices running in to the Wesley Brook. Here gunge has been stopped in its tracks by branches jammed against the supports of the bridge.

I did not have much luck identifying craneflies this morning. This apparently dark-winged specimen was on a street lamp pole pre-dawn.

The main problem was dew. One of 13 craneflies on the walls of the Telford Sailing Club HQ. all of which evaded identification.

What exactly are these two doing?

Or these two come to that. All the photos on the web of mating pairs shows them end-to-end rather than with one contorted which would be the only possibility here.

Also somewhat dew-spattered is this Long-jawed Orb-web Spider Tetragnatha sp. in its web.

I cannot suggest an identification for the slug on a wall of the Telford Sailing Club HQ. I can find no photos of. essentially. black slugs with paler spots.

Also on the Telford Sailing Club HQ was this Girdled Snail Hygromia cinctella, one of three similar-looking snails probably all this species.

Plane of the day. This is what the RAF called an Airbus Voyager KC.2. Airbus know it as an A330-243MRTT (Multi-Role Tanker Transport) indicating it can be use for trooping, freight-carrying and air-to-air refuelling of any aircraft with NATO-conformant recipient capability.

The FlightRadar24 data. Typically the aircraft will not publish a flight plan so the destination and purpose of any flight will not be revealed. Air Traffic Control (ATC) will be given sufficient data to ensure separation from commercial traffic.

The Flash: 09:25 – 10:30

(223rd visit of the year)

Bird notes:
- I have no idea why there were so few Moorhens. I hope they have not all been run over.
- Skylarks passing in Autumn do so just above my visual range, often in small groups. I have to try and point my binoculars in the direction of their flight calls to determine how many there are.

Bird(s) noted flying over here:
- 132 Jackdaws: in four groups
- 4 Skylarks at least: see notes
- 1 Redwing

Warblers noted.
None

Noted on / around the water:
- 5 Canada Geese: four of these arrived together
- 6 + 3 (1 brood) Mute Swans
- 37 (26♂) Mallard
- 117 (?♂) Tufted Duck
- 6 Moorhens
- 154 Coots
- 3 Great Crested Grebes
- 1 Black-headed Gull
- 1 Cormorant

Noted around The Flash:

Butterflies:
- *1 Comma Polygonia c-album

Bees, wasps etc.:
- 3 Common Wasps Paravespula vulgaris

Hoverflies:
- 1 Common Dronefly Eristalis tenax

Beetles:
- 2 Alder Leaf Beetle Agelastica alni

Bugs:
- *1 Common Flower Bug Anthocoris nemorum
- 8 Nettle Groundbugs Heterogaster urticae
- 1 adult Common Green Shieldbug Palomena prasina
- *1 possible Gorse Shieldbug nymph Piezodorus lituratus

A Comma Polygonia c-album on the about-to-flower Ivy bank. Only the third butterfly species I have seen here all year – a truly dire year for this group of insects.

A Common Flower Bug Anthocoris nemorum. Seems late in the year: not many flowers around now.

Not positive about this. It is a nymph of a bug. My best suggestion is a Gorse Shieldbug Piezodorus lituratus. Not a species I am familiar with. The nearest Gorse plants are around the upper car park of The Priorslee which is not that far from where I found this.
