Priorslee Balancing Lake and The Flash

5.0°C > 9.0°C: A clear start with high cloud encroaching from the West. Light south-easterly wind. Good visibility with haze and mist over the water again.

Sunrise: 05:50 BST

* = a species photographed today.

Priorslee Balancing Lake: 05:05 – 06:15 // 07:35 – 09:35

(103rd visit of the year)

Bird notes:
- once again the pair of Gadwall did their 'appearing' trick on the south-west grass: by 08:45.
- the duck Pochard still present.
- yesterday I thought I might have seen a second Cetti's Warbler. I was probably mistaken. The singing bird chased another bird in the same area today but that turned out to be a *Dunnock.
- four Sedge Warblers heard singing. All of them in the same place as yesterday.
- Blackcaps numbers back to full strength.
- what I presumed was the same Lesser Whitethroat was mostly heard singing from the dense Hawthorns alongside the West end path. It made at least two forays across the path and was seen in the bushes around the sailing club's boat yard where it seemed to be pursuing another though I did not see that well-enough to positively identify it.
just a pair of Common Whitethroats noted at the West end. The previously photographed bird along the South side not seen or heard.

Bird(s) noted flying over here:
- 3 Canada Geese: a single and a pair outbound
- 14 Wood Pigeons
- 1 Herring Gull
- 1 Lesser Black-backed Gull
- 62 Jackdaws

Counts from the lake area:
- 12 Canada Geese: of these two pairs and a trio arrived separately
- 1 Greylag Goose: briefly
- 2 Mute Swans: one on the nest throughout
- 2 (1♂) Gadwall
- 5 (4♂) Mallard
- 1 (0♂) Pochard
- *8 Moorhens again
- *23 + 5 (2 broods) Coots again
- 7 Great Crested Grebes
- 1 Lesser Black-backed Gull: adult seen leaving the football field c.06:05 again
- 1 Cormorant: arrived; a different bird to that seen yesterday
- 1 Grey Heron: flew across the water c.05:30 and not seen again

Hirundines etc. noted:

Warblers recorded (the figure in brackets is birds noted singing):
- 1 (1) Cetti's Warbler

- 18 (18) Blackcaps
- *1 (1) Garden Warbler
- 1 (1) Lesser Whitethroat: perhaps a second
- *2 (1) Common Whitethroats

On the West end street lamp poles pre-dawn:
Nothing noted. Too much dew?

Noted elsewhere:

Hoverflies:
*female Tapered Dronefly Eristalis pertinax

Alder Flies:
Alder Fly Sialis lutaria

Other flies
*unidentified midge sp.

Spiders:
*Bridge Orb-web Spider Larinioides sclopetarius

New flowers for the year:
*Red Dead-nettle Lamium purpureum

A clear if hazy start.

No real colour, just a tinge to the haze layer.

If you look hard there is a sliver moon showing in the eastern sky.

Moorhens and Coots usually manage to tolerate each other. This Moorhen is taking no chances.

Mrs. Blackbird with nesting material (a nest?).

"Now where is home? I can't see". It seems late for this species to be nest-building. A replacement nest for one destroyed by the tree cutting?

"Perhaps it is over there".

"Or that way?" Note the single white-tipped feather on the back. This species is known for the frequency of stray white feathering.

As I did yesterday I saw the male Cetti's Warbler chase after another bird that I thought might be a mate. Not so: it was this other rufous and brown bird – a Dunnock.

It would be a good photo without the twig.

The Common Whitethroat at the West end. This is the male who had just completed a dancing display flight.

Some you win... This is a Garden Warbler sitting in dappled sunlight. Would it show any better? Nope. Remember this species is recognised by having no distinctive features! For a warbler it is larger than most, unmarked grey and brown and with a stout all-dark bill. I hope to do better.

A female Tapered Dronefly Eristalis pertinax.

A very distinctive-looking midge. Despite this I have been unable to get an identification on it. I found it on the wall of the sailing club HQ.

"Me and my shadow". A Bridge Orb-web Spider Larinioides sclopetarius, also on the wall of the sailing club HQ.

Not fully open and covered in dew this is Red Dead-nettle Lamium purpureum.

In the Priorslee Avenue tunnel:

Flies
*7 Psychodidae sp. [Drain Fly, Moth Fly or Owl Fly]
various *craneflies and midges

Arthropods:
*1 White-legged Snake Millipede Tachypodoiulus niger

I still can't work out what species of cranefly this is. I photographed one like this yesterday.

One of no fewer than seven Psychodidae sp. [Drain Flies, Moth Flies or Owl Flies] on one wall of the tunnel.

And a White-legged Snake Millipede Tachypodoiulus niger. I have seen hardly any of these this year so far: I suspect the dry weather.

The Flash: 06:20 – 07: 30

(100th visit of the year)

Bird notes:
- a visiting pair of Mute Swans was being seen off by the resident cob just as I arrived.
- again two Great Crested Grebes noted, and again only loosely together and not particularly close to the island either.

Bird(s) noted flying over here:
- 1 Herring Gull: immature
- 1 Lesser Black-backed Gull: adult
- 5 Jackdaws: singles

Noted on / around the water:
- 18 Canada Geese again
- 3 Greylag Geese again
- 3 Mute Swans: a pair chased off; the other resident presumed to be on the island.
- 18 (16♂) Mallard
- 12 (7♂) Tufted Duck
- 6 Moorhens
- 26 + 6 (1 brood) Coots
- 2 Great Crested Grebes

Warblers recorded (the figure in brackets is birds noted singing):
- 6 (5) Chiffchaffs
- 5 (5) Blackcaps

Noted elsewhere:
*1 possible Robber fly Dioctria sp.

A flying Jay.

 "Do you want a photo of me?"

"This is my best photo pose". A cooperative Song Thrush.

I found this high up on one of the street lamp poles. As far as I can determine it is possibly a Robber fly Dioctria sp.
