Priorslee Lake and The Flash

7.0°C > 8.0°C: Early broken clouds soon gave way to low overcast and light rain. Later medium overcast, still with sporadic light rain. Calm start again. Light SE breeze later. Good visibility.

Sunrise: 07:51 BST

* = a photo today.

Priorslee Lake: 06:20 – 09:41

(228th visit of the year)

The often low cloud seemed to restrict any visible migration.

Bird notes:
- The Mute Swan cygnets did one and a half circuits of the lake with both left- and right-hand turns accomplished. The adults accompanied them for take-off only and then looked on.
- Fewer Lesser Black-backed Gulls flying from the N / NW between 07:15 and 07:30. I logged 264 with only 16 of these flying over leaving 248 on the lake for a while. Unlike previous days when arrival has been 'steady' the first 147 arrived before a gap of several minutes for the next arrivals.
- After 08:50 another 58 Lesser Black-backed Gulls arrived from the N, the E and the S; four Herring Gulls with them. 15 flew over without stopping.
- A brief sighting of a flying first-year gull was a candidate for a Yellow-legged Gull. I was unable to relocate it to get further evidence.
- A tight post-roost Jackdaw group of c.350 birds was followed by another scattered group of c.80 and some while later by 42. A few singles / duos made for a decent count. No identified Rooks
- A late Chiffchaff calling here.
- Many Song Thrushes around the berries – at least 10 seen. Also what seemed like many more Blackbirds than usual. Rather fewer Redwings though.

Playing fields
Not visited

On / around the street lights etc. pre-sunrise:
- 10 November Moth-types (Epirrita sp.).
This is frustrating. There are several other species of moth flying at the moment but none seems to want to come here.
- 2 winter gnats (Trichocera sp)
- 1 Tipula pagana cranefly
- *1 Ula sylvatica (a Hairy-eyed Cranefly)
- *1 presumed stretch spider Tetragnatha sp.
- 1 Dicranopalpus ramosus-type harvestman

Noted later:
- 2 Grey Squirrels again
- *different species of fungus.
- I noted both flowers and seeds of Shepherd's-purse (Capsella bursa-pastoris). For some inexplicable reason this species did not feature in my log for here – surely I must have seen it previously?

Pity about white van-man somewhat spoiling the view. A brief sunrise gave me no chance to find a better vantage point.

Dull weather makes for pastel shades of Autumn colours.

Three of the Mute Swan cygnets making their left-hand turn, all flying strongly now.

A Great Tit having a shake.

Another species of fungus found on the edge of the football field. It has a passing resemblance to some of the Bonnets (Mycena sp.) though the rather fibrous-looking cap does not seem to match any specific member of that group. Another fungus identification failure.

A trio in close-up.

The side-elevation view reveals a fourth.

I was concentrating on getting a picture of the spider and did not notice the fly until I was back home sorting the photos. The spider looks rather more delicate than the usual Tetragnatha spiders, but that is what I think it is. The fly matches photos on the web of the Hairy-eyed Cranefly Ula sylvatica. This is a new species for me.

The spider on its own. It has tucked its third pair of legs up.

The Flash: 09:44 – 10:42

(213th visit of the year)

A reasonable sprinkling of birds overhead without being spectacular.

Other bird notes:
- Tufted Duck numbers have increased again after the dip earlier in the week..

Birds noted flying over / near The Flash:
- 1 Common Buzzard
- 6 Feral Pigeons (one group)
- 9 Wood Pigeons
- 1 Rook
- 48 Fieldfare (three groups)
- 7 Redwings (two groups)
- 1 Pied Wagtail
- 2 Siskins

Counts from the water:
- 3 + 7 (1 brood) Mute Swans
- 6 Greylag Geese
- 15 Canada Geese
- 41 (23♂) Mallard
- 69 (>26♂) Tufted Duck
- 3 brownhead Goosanders
- 1 Grey Heron again
- 2 Great Crested Grebes again
- 10 Moorhens
- 37 Coots again
- 36 Black-headed Gulls
- 1 Lesser Black-backed Gull: first-winter

On various lamp poles:
- 3 November Moth-type (Epirrita sp.)
- 3 Common Wasps (Vespula vulgaris), two of these on the light sensor of their usual lamp
- *2 Dicranopalpus ramosus-type harvestmen
- *1 Opilio canestrinii harvestman

On / around the Ivy
Nothing of note.

A Dicranopalpus ramosus-type harvestman with the long palps. A typical resting position with the legs bunched and held at right angles to the body. There are two similar species which can only be separated by detailed examination of their privates.

Half a harvestman of the same group. So where have the other four legs gone? Note it has aligned the middle leg on the left with a mark in the lamp pole. Was this by accident or was it attempting a camouflage?

An Opilio canestrinii harvestman.

Here I have zoomed in on the eye. This was because I thought it was a Leiobunum rotundum-type and I needed to see the eye-ring. Only then did I realise it was the wrong shape anyway!

This is the fungus which I provisionally identified as Honey Fungus (Armillaria mellea) on the 9th October. It is now collapsing in to a soggy heap.
