Priorslee Lake and The Flash

9.0°C > 13.0°C: Clear except to very far E. A few clouds later. Moderate, fresh at time, NNW breeze. Very good visibility.

Sunrise: 06:16 BST

* = a photo today.

Priorslee Lake: 04:57 – 06:45 // 07:45 – 09:15

(177th visit of the year)

Bird notes:

- An adult Little Grebe was seen in the NE area. Recently calls have been from the NW area (but not for the last three days)
- At least 50 Black-headed Gulls had arrived by 06:05 with at least 70 more in flight to the NW. At this time a Kestrel flew through going W and all the birds dived for the water with >220 noted by 06:10. Some moved away very shortly afterwards (see the totals of birds on the foot ball and academy playing fields), although more stayed than recently recorded. 82 were present at 07:50.
- A male Pheasant was flushed from the SW grass at 05:50, An unusual date for a sighting here.
- 37 presumed House Martins seen flying W high and a long way to the N of the lake at 06:15. None was seen over the lake or the estate at this time or shortly afterwards. At least, possibly the some of the same birds, were feeding in the shelter of the trees along the N side by 08:15. There was at least one Sand Martin with these birds.
- Up to 10 Song Thrushes were singing here well in to June and a small number sang until 8th August. I have noted just two non-singing birds since that date. While these are rather shy birds when not singing and often crepuscular their absence is puzzling.
- At least two, probably three and possibly four pairs of Reed Buntings bred here and numerous juveniles were seen. It is now two weeks since I saw or heard one. Where have they gone?

Birds noted flying over / near here:

The full list of things noted:

- *Common Carder Bee (Bombus pascuorum)

- *Lesser Hornet Hoverfly (Volucella inanis)
- *Common Darter (Sympetrum striolatum)
- Harlequin Ladybird (Harmonia axyridis)
- 5 Pipistrelle-type bats

Good to have a sunrise at last.

One sunrise photos deserves another.

And another.

An adult Little Grebe put in a brief appearance. Note the yellow spot at the base of the bill. The chestnut head is catching the sun.

Very many Chiffchaffs around at the moment, mostly gleaning insects from tree-tops. This one came lower. Compare how the supercilium looks when compared with...

..this view from below. Dark legs and the pale base to the lower mandible confirm the identity (it real life it was sub-singing to make it even easier).

I had to conclude this butterfly was a Large White (Pieris brassicae). The inner edge of the black on the wing tip is certainly not almost straight as it would be on a Small White (Pieris rapae). But neither does it curve and extend well down the trailing edge as is normal in Large White. This is a female – the black spot on the hind wing can just be seen through the lower edge of the forewing.

Not the best angle on the best specimen of Square-spot Rustic moth (Xestia xanthographa) to date. Had to shoot upwards to avoid branches.

There were several splendid-looking Common Carder Bees (Bombus pascuorum) this morning. Here is one.

I know how this one feels – a bit thin on top.

And another

The third one from another angle.

Close-up reveals that this Tapered Drone-fly (Eristalis pertinax) is quite hairy – even the legs.

The folded wings don't help but enough of the markings are visible to identify this as a Lesser Hornet Hoverfly (Volucella inanis).

For a change a male Common Darter (Sympetrum striolatum). Not as red as it will become later in the year.

One of the most distinctive harvestman is this Dicranopalpus ramosus with its long and hooked palps.

Not one of the usual harvestmen that I am seeing at the moment. Scuttling away in the dark does not make for crisp photos. I think a female Mitopus morio.

The Flash: 06:50 – 07:40

(162nd visit of the year)

Many geese already present when I arrived (probably the birds seen inbound over the lake earlier). More arriving all the while. Made it difficult to find other birds on the water with the geese moving around and clambering on to the island.

Other bird notes:

- Since Tuesday I have inexplicably reported just five Mute Swan cygnets as present. All seven have been present throughout.
- My first sighting of the trio of Greylag x Canada Geese for several weeks.
- Yesterday I reported a possible hopeful Coot still sitting on a nest. Today there was one very small and very late juvenile around the nest.
- Another Willow Warbler singing. Has been a good Autumn passage for this species.

Birds noted flying over / near The Flash:

- 3 Common Buzzards
- 2 Feral Pigeons
- 3 Stock Doves
- 7 Wood Pigeons
- 3 Jackdaws

Hirundines etc. logged:

- 2 House Martins again

Count of warblers logged (singing birds in brackets):

- 2 (0) Chiffchaffs
- 1 (1) Willow Warbler
- 1 (0) Blackcap

Counts from the water:

- 3 + 7 (1 brood) Mute Swans
- >48 Greylag Geese: 47 of these noted arriving
- 3 Greylag x Canada Geese: arrived
- >178 Canada Geese: 126 of these noted arriving
- *24 (15?♂) Mallard
- 17 (6?♂) Tufted Duck
- 2 Great Crested Grebes
- 9 adult and juvenile Moorhens
- 73 adult and juvenile Coots
- 1 Black-headed Gull

On various lamp poles:

Moth:

- 1 Elbow-stripe Grass-veneer (Agriphila geniculea)

Other things

- 1 plumed midge (Chironomus plumosus)

Otherwise:

- 1 Grey Squirrel yet again..

The Mallard seem to be celebrating completion of their wing-moult and are now doing much flying around. Here a trio caught by the early sun. Two drakes and (bottom left) a duck with the darker belly.

This drake has yet to get full breeding plumage – the chestnut on the neck is rather patchy.

The neck on this drake is less patchy but there is more pale behind the bill.

Between the lake and The Flash:

Of note 

- *1 Large Yellow Underwing moth (Noctua pronuba): still more or less in the same place in the tunnel as previously.

The Large Yellow Underwing moth (Noctua pronuba) had moved a bit and was better orientated this morning so it appears for the third day.
