Priorslee Balancing Lake and The Flash

8.0°C: A cloudy start. Light rain after 07:45 became heavier and heavier with the cloud descending, Very dull and by the time I left The Flash the cloud was covering the tops of the trees. Light south-easterly breeze. Very good visibility becoming moderate at onset of the rain.

Sunrise: 08:22 GMT once more
* = a species photographed today

Priorslee Balancing Lake: 06:30 – 09:20

(2nd visit of the year)

Bird notes:
- 26 Black-headed Gulls arrived at 07:49 with eventually c.130 on the water. Some 20 minutes after they had appeared to begin leaving I noted about the same number all over the south-west grass and adjacent lake. How many of these were new arrivals rather than returnees?

- 29 Wood Pigeons: of these 23 flew low West together

Birds seen leaving roosts around the lake.
None

- 2 + 2 Mute Swans
- 4 (3♂) Mallard
- 26 (11♂) Tufted Duck
- 13 Moorhens
- Coots not counted
- 1 Great Crested Grebe
- c.130 Black-headed Gulls
- 5 Herring Gulls
- 1 Yellow-legged Gull
- 9 Lesser Black-backed Gulls
- 2 Grey Herons: as so often, one of these chased off

The (semi) nocturnal community on or around the street lamp poles pre-dawn:

Moths:
- none

Flies:
- 1 fly
- 1 barkfly Ectopsocus sp.

Beetles:
- 1 unidentified small ground beetle

Other insects:
- 9 at least springtails Pogonognathellus/ Tomocerus type
- 2 at least unidentified globular springtails
- 1 Tawny Soil Slug Arion owenii

Spiders:
- 1 Stout Sac Spider Clubiona sp.

Nothing noted

New Bird Species
Bird species added today to the year list from here were:
38 Reed Bunting: calling from the South side
39 Common Buzzard: over fields to the East.
40 Grey Heron: a newly arriving bird chased away by a previously unseen bird.
41 Great Crested Grebe: adult
42 Yellow-legged Gull: adult arrived
43 Mistle Thrush: singing by the Castle Farm Way gate: unusual here. Another singing later alongside Teece Drive

This is a barkfly Ectopsocus sp. The separation of the individual species requires genitalia examination.

A collection of springtails. Just how many species are involved here? Top right and bottom left are likely to be Pogonognathellus longicornis. The others?

Oh look: two more!

And two more here with a Tawny Soil Slug Arion owenii.

All these spiders were found on just one of the street lamp poles. This pole, the last one on the path walking towards the M54, often has multiple spiders not usually all of different species. Here we have, clockwise from the top left: a dew-covered Nursery Web Spider Pisaura mirabilis; a male Long-jawed Orb-web Spider Pachygnatha clercki; Stout Sac Spider Clubiona sp.; and Mothercare Spider Phylloneta sisyphia, a Comb-footed spider. As usual help from Obsidentify with these.

Probable Glistening Inkcap fungus Coprinellus micaceus. They are likely to be glistening more than usual by the rain sluicing down on them. A few of these were noted last month nearby. This large group probably also arose from the felling of a tree nearby.
