Priorslee Lake and The Flash

Bird notes:
- Low number of geese logged. More heard. Since yesterday they have changed their feeding location and most flew off S, far to the E, obscured by vegetation from my usual vantage point.
- A juvenile Common Buzzard made a brief flight around the Ricoh copse, still managing to call for food as it did so.
- The Common Sandpiper either survived the Saturday disturbance or is yet another.

This was the clearest the skies got this morning.

A Cormorant (or Black Death as the fishermen call them) poses regally.

"Get off that buoy: it is MINE"

"I'm the king of this buoy. You can kiss my feet if you like"

This Grey Heron makes a study in concentration.

The newer of the broods of Great Crested Grebe. One of the adults arrives with breakfast for the youngsters.

One juvenile reaches to grab the offering

And the adult watches as the small fish disappears.

An adult Common Buzzard ignores a disgruntled Magpie.

Almost too close. Never noted the wing-tips of a Black-headed Gull curl up like this.

A moth sitting, unusually, with its wings closed. Still under investigation.

This resting Red-tailed Bumblebee (Bombus lapidarius) was posing well.

Long Hoverflies (Sphaerophoria scripta) are really small – compare with the Ragwort flower for size.

A shieldbug instar. Not 100% sure of species – the web really only illustrates the instars of Common Green Shieldbug (Palomena prasina). This looks too dark green for that species. So?

The Flash: 06:15 – 07:20

(139th visit of the year)

Bird notes:
- After two days with missing resident Great Crested Grebes I logged an additional adult.
- A new brood of Coots seen – just two peering out from under the parent's belly. Perhaps more being brooded.

Birds noted flying over / near The Flash:
- 1 Sparrowhawk
- 3 Lesser Black-backed Gulls: two, at least, adults
- 5 Feral Pigeons (one group)
- 2 Stock Doves
- 7 Wood Pigeons

Hirundines etc. logged:
- 4 House Martins

Count of warblers logged (singing birds in brackets):
- 4 (0) Chiffchaffs
- 1 (0) Blackcap

Counts from the water:
- *3 + 7 (1 brood) Mute Swans
- 1 Greylag Goose

- 14 (?♂) Mallard
- 27 (9?♂) Tufted Duck

- 31 adult and juvenile Coots
- 5 Black-headed Gulls: flew in
- 1 Lesser Black-backed Gull: (near) adult, briefly
- *1 Kingfisher

On different lamp poles:
Moths
- None: the Swallow Prominents (Pheosia tremula) have moved on (or been eaten!)
and
- 1 unidentified caddis fly sp.
- 2 Common Wasps (Vespula vulgaris)
- 2 Dicranopalpus ramosus (harvestmen)
- *2 Leiobunum rotundum (harvestmen)

Otherwise
- 1 Grey Squirrel.

The cob Mute Swan on the warpath chasing his daughter from 2018. It must be about a year since I last saw her fly so I am not sure what the outcome will be. She normally hides back on the island.

You will have to peer hard in the middle of this photo – where you can see a Kingfisher. The island is a long way away to photograph small birds. It is often a surprise to note that from the front very little blue shows, just a deep brick red.

Two Leiobunum rotundum harvestmen. At least I think they are – there is another less common and very similar species. Need to see the colour of the eye surrounds to be sure – 15 feet up a lamp pole that is unlikely.
