Priorslee Lake and The Flash

11.0°C > 13.0°C: Clear enroute with low stratus spreading quickly across the whole sky. Lifted somewhat but stayed cloudy. Calm start with light NNE breeze later. Good visibility.

Sunrise: 04:47 BST yet again

* = a photo today

Priorslee Lake: 04:15 – 05:20 // 06:15 – 08:05

(131st visit of the year)

Bird notes:
- A Pheasant calling, apparently from somewhere along the N side: I have not heard any here for several months.
- A duck Mallard with three small ducklings is the third brood I have seen here this year. None of the others has survived.
- The Swifts slept in today, the first arriving at 05:05 with just six soon afterwards. Juts one seen in the distance later.
- Just one Garden Warbler heard singing and some way from any previously noted locations in the SW area.
- c.60 Starlings in the area, many of them juveniles. I counted 42 on the academy playing field and others calling from the hedges when another party of 14 arrived.

Overhead:
- 5 Wood Pigeons
- 2 Common Buzzards again
- 2 Lesser Black-backed Gulls: ages not determined
- 2 Cormorants: singles
- 2 Jackdaws

Hirundines etc., noted:
- c.6 Swifts

Warblers noted (the number in brackets is singing birds):
- 14 (10) Chiffchaffs
- 1 (0) Sedge Warbler
- 10 (6) Reed Warblers
- 14 (13) Blackcaps
- 1 (1) Garden Warblers
- 3 (2) Common Whitethroats

Count from the lake area
- 2 + 5 (1 brood) Mute Swans
- *9 (8♂) + 3 (1 brood) Mallard
- 4 + 2 (1 brood) Moorhens
- 33 + 21 (7 broods) Coots
- 6 Great Crested Grebes still
- 1 Grey Heron: departed

On / around the street lamps pre-dawn:
- 1 Bridge Orb-web Spider (Larinioides cornutus)
- 1 Stretch spider sp (Tetragnatha sp.)

Noted later: not much in the dull conditions.

Moths:
- Timothy Tortrix (Zelotherses paleana)
- *Green Oak Tortrix (Tortrix viridiana)
- Common Marble (Celypha lacunana)

Other flies:
- *Black Snipefly (Chrysopilus cristatus)
- Grouse Wing (Mystacides longicornis) [caddis]
- *unknown fly reminiscent of a semaphore fly

Spiders:
- *possible Common Candy-striped Spider (Enoplognatha ovata)

Molluscs:
- *Glass snail sp.

Also
- *unknown possible beetle larvae

The duck Mallard allowed me to photo two of her three ducklings on a brief foray out of cover of the reeds.

I flushed this pale moth and it remarkably was then happy for me to get close to photo it. I has a typical Tortrix moth shape and seems to be a rather faded Green Oak Tortrix (Tortrix viridiana). Most of those that I have seen previously have been a quite bright green.

I thought this looked a bit small for a Black Snipefly (Chrysopilus cristatus). Looking in detail at al Steven Falk's photos of snipe flies on the web I cannot provide any better identification. It cannot be a Little Snipe Fly (Chrysopilus asiliformis) as that has bright green eyes.

With white wing-tips I thought this might be a fly related to yesterday's Semaphore fly (Poecilobothrus nobilitatus). Compared to that species this shows less white on the wing tips and the thorax is brown and not green. I cannot match it with photos on the web sites I use.

This tiny snails looks like a glass snail sp. I don't think I'll be able to get a more specific identity.

This green spider with prey is reminiscent of the Common Candy-striped Spider (Enoplognatha ovata) but the abdomen shape seems wrong. I'll have to get it checked.

Another one I need help with. I have no idea what this tiny creature might be. I assume a beetle larva?

Between the lake and The Flash:

- The Chiffchaff was still singing, rather intermittently, by the lower pool.

Nothing noted on the roof of the Priorslee Avenue tunnel.

The Flash: 05:25 – 06:10

(116th visit of the year)

Bird notes:
- Just one well-grown juvenile Coot. Perhaps some others were being brooded.
- I eventually managed to see the Great Crested Grebes lurking under an overhanging fallen tree – thanks to two Greylag Geese that invaded their space and put them briefly in the open.

Birds noted flying over here:
- 2 Jackdaws

Hirundines etc., noted:
None

Warblers noted (the number in brackets is singing birds):
- 2 (2) Chiffchaffs
- 3 (3) Blackcaps again

On /around the water:
- 128 + 1 Canada Geese
- 34 Greylag Geese again
- [no Greylag x Canada Goose located]
- 3 + 2 (1 brood) Mute Swan
- 31 (22♂) Mallard: no ducklings seen
- 9 (7♂) Tufted Duck
- 4 + 2 (1 brood) Moorhens
- 1 juvenile Coot: see notes
- 2 Great Crested Grebes

Nothing else of note.

The juvenile Canada Goose has managed to evade the attentions of the cob Mute Swan ... so far. Note the loose primary feather in what I assume to be one of its parents alongside.

The male Blackbird does not look convinced about the absence of bread! He also looks in need of a good moult as the breeding season draws to a close.
