Priorslee Lake and The Flash

14.0°C > 24.0°C: Fine and sunny throughout. Calm start: light SE wind later. Very good visibility with a haze layer above.

Sunrise: 05:28 BST

* = a photo today.

Priorslee Lake: 04:14 – 06:05 // 07:05 – 09:37

(151st visit of the year)

The first bird singing this morning was a Robin. They have been quiet for a few weeks while they moult. Both sexes will start to sing to set up winter feeding territories. The Reed Bunting was next to sing. Then just two Song Thrushes.

Other bird notes:
- The seven Canada Geese arrived on the water, having peeled off from one of the inbound groups.
- The second brood of Great Crested Grebes was unexpected because their nest must have been very close to that of the earlier brood. The bird sitting in the SE corner was off the nest this morning. Three eggs were visible.
- A Hobby flew fast E at 07:50.
- Another small passage of Lesser Black-backed Gulls moving S. Yesterday they passed overhead c.05:45: today to the W after 08:00
- Many small groups of Swifts. Hard to know how many birds involved. Did they return or were they all different. Up to six at any one time.
- The Barn Swallows included a group of four, two of which had short tail streamers suggesting a family party of two adults and two juveniles.
- Five House Martins arrived overhead, apparently from the S at 05:10. Later c.30 were high over the lake / estate. I have often wondered where the early-brood juveniles roost when later broods are in the nest. Perhaps the early arrivals were birds that roosted nearby returning to their home range?

Clear, calm mornings do not make for an interesting sunrise. Better than all the recent dull days though.

A Cormorant dropping in. The long tail always touches the water first even though the feet are in 'brace' position.

Standby for several Great Crested Grebe photos. Here is the original brood of two juveniles with one of the parents.

The other providing breakfast for whoever gets there first.

A gentle hand-over (bill-over?).

Close-by there are two much smaller juveniles peering out of this adult's back.

With feathers fluffed up it is hard to know how many young there are.

Meanwhile this pair are still in love but show no sign of nest-building.

This Great Crested Grebe was off the nest and showing three eggs. Is it allowing the sun to warm the eggs? Or are they about to hatch?

I chopped this Black-headed Gull's wing-tip off but it is useful in showing the moult happening. In addition to messy-looking primaries a number of secondary coverts are regrowing and there is a square of white in the wing where they are missing and allowing the light to shine through.

An interesting moult effect makes this Black-headed Gull look ring-necked. Another bird in serious wing-moult.

In the warm-light of early morning an immature Herring Gull, also in moult. Both outer secondaries and outer primaries are missing as are most of the tail-feathers – the feet should not stick out beyond the tail like this.

Rooks normally pass early and with the sun behind them. This exception allows the long pointed bill with the bare skin at the base to be seen to good effect. The bare skin is likely for the same reason that some vultures have bare heads. Where they stuck their beaks to eat – in the case of Rooks soft earth - would make feathers a matted mess. Another bird in wing-moult.

A new moth for me in Shropshire is this Small Seraphim (Pterapherapteryx sexalata).

My first Phoenix moth (Eulithis prunata) here this year – I saw one between the lake and The Flash five days ago.

A Dun-bar moth (Cosmia trapezina) and unknown friend. A consistent emergent date – I last recorded this species on 2nd August 2019.

This seems to be my first-ever Gypsy Cuckoo Bee (Bombus bohemicus). Features are the white tail: the very thin white midriff band: and the white collar with the buff centre section.

This bee is a puzzle. It looks much too hairy for an Andrena mining bee. Yet it seems too small and not hairy-enough for any of the Bombus bumblebee-types.

A splendidly fresh example of a Green-veined White butterfly (Pieris napi). The veins still don't really look green but you can see why they could be thought that way.

A smart Red Admiral butterfly (Vanessa atalanta). I am pleased that my newer camera shows this as truly 'red' - my other camera seemed to want to invent an 'Orange Admiral'.

Unless you know then this butterfly at this angle would be a challenge to identify

Easier from top side! A Peacock (Aglais io).

A male Common Darter (Sympetrum striolatum). This specimen is more mature than the one I photographed a fortnight ago – this one is acquiring the adult red colour.

The Flash: 06:10 – 07:00

(137th visit of the year)

Bird notes:
- All but two of the Mallard were inside the island. There is only a limited view to see them.
- Likewise some Tufted Duck were also lurking there are hard to see and harder to sex.
- Only one adult Great Crested Grebe found.
- Strangely no Black-headed Gulls.
- The Blackcap with the aberrant song was singing as I arrived but was not heard later.

Birds noted flying over / near The Flash:
- 1 Sparrowhawk again
- 8 Feral Pigeons (three groups)
- 2 Wood Pigeons
- 1 Jackdaw

Hirundines etc. logged:
- 4 Swifts
- 8 House Martins

Count of warblers logged (singing birds in brackets):
- 6 (0) Chiffchaffs again
- 1 (1) Blackcap singing only very briefly

Counts from the water:
- 2 + 7 (1 brood) Mute Swans
- 3 Greylag Geese: two flew off
- 5 Canada Geese
- 25 (?♂) Mallard (see notes)
- 20 (7?♂) Tufted Duck
- 1 + 2 (1 brood) Great Crested Grebes
- 5 + 5 (3 broods) Moorhens
- 31 adult and juvenile Coots
- no Black-headed Gulls

On different lamp poles:
Moths
- *2 Swallow Prominents (Pheosia tremula): these on the same lamps as yesterday; one of them in a different position.
and
- 1 Common Wasp (Paravespula vulgaris)

Also
- 1 Grey Squirrel yet again: still munching haws from the same bush.

I've found another clump of Purple-loosestrife (Lythrum salicaria) that does not need thigh-waders to get close. Indeed I took this from dry ground.

It is a pity about the cars cluttering the place. In the early light and with reflections in the calm water it is an eye-catching view. I should be working for an estate agent.
