Priorslee Lake and The Flash

Priorslee Lake: 07:35 – 10:15
The Flash: 07:15 – 07:30 // 10:20 – 10:35

c.9.0°C > c.14.0°C: Fine and clear with persistent con-trails making it rather hazy. A few puffy clouds later. Mainly light E breeze. Good visibility, becoming very good.

Sunrise: 04:48 BST again

Priorslee Lake: 07:35 – 10:15

(70th visit of the year)

I again spoke with the contractors cutting the weed in the lake. They confirmed that their contract did not cover removal of the weed from alongside the water where the cut weed has been piled up. It seems it is the Yacht Club’s responsibility

Notes from today:
- several Buzzards seen around the lake. I am used to seeing these harried by Carrion Crows (never Rooks it seems). This morning they were getting a hard time from the
- in the fine weather the broods of Coots were out and available to count. Still seem to be doing less-well here than at The Flash
- an immature Lesser Black-backed Gull dropped in briefly: my first gull on the water for weeks
- at least two groups of Long-tailed Tits with juveniles: one part of at least 9 birds
- must have been the cooler weather yesterday that inhibited warbler song – back to normal numbers today. Indeed there seemed to be a 4th Garden Warbler singing: as previously noted these birds are mobile within their territories yet these are close-together making it hard to sort them out
- several juvenile (Common) Whitethroats seen today
and

- Common Blue Damselfly
- Azure Damselfly
- Blue-tailed Damselfly
- Red-eyed Damselfly

- Mystacides longicornis – caddis flies
with
- a Rhagonycha fulva (Common Red Soldier Beetle aka Hogweed Bonking-beetle)
- a few Common stretch-spiders (Tetragnatha extensa)

A fine study of a Common Buzzard overhead.

Rather distant but here is a bird hovering again.

Not quite so serene here with two Magpies in hot pursuit (of a rather distant bird). I cannot recall ever having seen Magpies do this.

They were giving it a good seeing off.

And would not let up.

Even further away a Jay was having go at another Buzzard. As with the Magpies I cannot recall having seeing Jays do this before either.

A trio of very new Coots with one of their parents.

Close-by were these two older juveniles. I paused long and hard over these: surely the bi-coloured bill means these are Moorhens? That species would show white along the flanks by this age so must be the way vegetation is wrapped around the bill.

One of the Speckled Wood butterflies. This species is more or less continuously brooded and can be seen in warm weather from March to November. That said my first this year!

This one was rather shy and shuts its wings. Not too often we see the underside.

Another specimen showing off.

I only had one shot at this Common Blue butterfly before it was off to places unseen. Sadly a waving grass stem in the foreground has slightly blurred things.

A very fresh Large Skipper butterfly with a clean neat yellowish tip to the wings.

My first-ever Broad-bodied Chaser dragonfly at the lake. I managed to see where it had landed and while this is a rather distant shot we can clearly see the brown marks at the base of the wing that identifies this species. This is a female – the males are blue. ‘Broad-bodied’ seems a suitable epithet.

A Red-eyed Damselfly. With the small amount of blue on the ends of segments 8 and 9 I think it has to be a male, the other marks suggest it is a teneral, yet to acquire the ‘proper’ colour.

This seems to be a Red-tailed Bumblebee (Bombus lapidarius) though the collar is rather more orange than I would expect.

This is a hoverfly of the genus Syrphus. Only females of S. ribesii and S. vitripennis can be separated and this looks like a male.

This hoverfly awaits positive identification.

Hard to fit in – ‘just’ a Common Crane-fly (Tipula oleracea).

This seems to be a Dolerus species of sawfly, and likely a female as most males in the genus are all-black. Specific identification is not possible from this picture.

This is the crane fly Mystacides longicornis that can be seen in dancing swarms around the edge of the lake. Superficially similar to the Yellow-barred Longhorn (Nemophora degeerella) moth this species has red eyes and dark marks across the wings.

Try as I might I could not persuade the camera to focus on the head of this spider. It seems to be a Common stretch-spider (Tetragnatha extensa) even though it is not looking ‘stretched’ here.

Two spikes of the orchid with spotted leaves. And ...

A close-up of the flowers showing the shape of the petals. I am now convinced this is a Common Spotted Orchid (Orchis (Dactylorhiza) fuchsii).

The small flowers of the Snowberry bush (Symphoricarpos albus).

Just opening is this Hedge Woundwort (Stachys sylvatica).

And a close-up as seen by pollinators!

The heap of cut Canadian Pondweed after two days. Should be large by the end of the week!

And

On the roof of the tunnel under Priorslee Avenue was this swift species of moth. Hard to be 100% certain but I think the width of the shoulder mark and the way the tip of body is curled up identifies this as a Common Swift.

The Flash: 07:15 – 07:30 // 10:20 – 10:35

(53rd visit of the year)

Notes from today
- both broods of Mallard ducklings well-seen today: it turns out BOTH have seven ducklings
- numbers of Tufted Ducks changes again!
- more broods of Coots out in the fine weather: one bird still sitting; another pair with an unfinished nest
- >40 Common Swifts in a tight swirling group today
- as expected the fine weather meant the Barn Swallows to the N could desert the wires they were sitting on conserving energy and had likely gone off hunting insects. So no photos

Birds noted flying over
- 1 Feral Pigeon

Hirundines etc. seen today
- >40 Swifts
- 2 House Martins

Warblers noted: figures in brackets is singing birds (not all the males seen might have been singing)

- 8 (5♂) Tufted Ducks

The ‘other’ younger group of ducklings and we see there are in fact seven in this brood too.
