Priorslee Lake and The Flash

Priorslee Lake:  04:10 – 05:40 // 06:40 – 08:45
The Flash:  05:45 – 06:35

15.0°C > 16.0°C:  Clear to E / SE with cloud soon arriving from the W and a few light spots of rain by the time I left. Light W wind. Very good visibility.

Sunrise: 04:53 BST

Priorslee Lake:  04:10 – 05:40 // 06:40 – 08:45

(168th visit of the year)

Best today was a Tawny Owl calling from somewhere in the Ricoh ground at 04:15.

Other bird notes from today
- The newest brood of small Mallard ducklings still clinging on with the lone survivor. The long-term two ducklings still with their mother but now almost full-grown and difficult to identify.
- The juvenile Great Crested Grebes in the NW area were not seen in the water: the adult was holding its back feathers as if there were still juvenile(s).
- Two adult Black-headed Gulls at 04:15 had probably roosted. 17 more arrived overhead at 04:40 with 15 of these leaving. Thereafter a few adults, perhaps the same birds, throughout.
- Two heavily moulting Lesser Black-backed Gulls stopped for a ‘gas and go’ at 04:55. Another adult arrived for a drink at 08:15 and then decided it wanted to stand on the only buoy which was already occupied by a Black-headed Gull. Having done so it reckoned without the Common Tern that was not about to share the water with such a brute and harassed it until it decided it was best to leave.
- The Common Tern arrived at 07:55 this morning.

After yesterday’s bonanza the lamp poles pre-dawn produced just
- 1 Small Fan-footed Wave moth (Idaea biselata)
- 1 Chironomus plumosus (plumed midge sp.)
Seen later, much reduced in cloudy conditions:
The following insects logged
- Butterflies (in species order):
- 1 Ringlet (Aphantopus hyperantus)
- Moths (in species order):
- 2 Garden Grass-veneers (Chrysoteuchia culmella)
- 2 Common Marble (Celypha lacunana)
- 1 possible Silver-ground Carpet, though this species should no longer be flying
- Damselflies etc. (alphabetic order of vernacular name):
- 2 Blue-tailed Damselfly only
- Hoverflies noted: only one species this dull morning
        - 5 Marmalade Hoverfly (Episyrphus balteatus)
Other things:
- >10 pupa of Harlequin Ladybirds (Harmonia axyridis)
- 1 Snipe fly sp.
- 1 Nephrotoma quadrifaria cranefly

Just before the cloud rolled in from the west there was a short sunrise – like this. 

The Common Tern passing by. 

Here as well. We see very clearly the dark primaries and the dark tip to the bill.

This seems to be a ladybird pupa .... 

... as does this rather differently-marked individual. I suspect therefore they are both from Harlequin Ladybirds (Harmonia axyridis), itself a variable species.

I was not able to get a plan view of this crane fly. However the well-marked wings suggest it is most likely Nephrotoma quadrifaria (no vernacular name).

A snipe fly sp. with its prey. Perhaps it is getting ready to present it as a gift to a female.

The Flash:  05:45 – 06:35

(161st visit of the year)

Notes from here:
- One very small duckling Mallard could have been another new brood. The other obvious juveniles were a reasonably well-grown trio.
- Many of yesterday’s Tufted Duck gone again.
- Confirmed there are still two Great Crested Grebe juveniles.
also
- 2 Grey Squirrels
- 1 Riband Wave moth (Idaea aversata) on a lamp pole.
- 2 Little Grey moths (Eudonia lacustrata) on different lamp poles.

Birds noted flying over / near The Flash:
- 3 Cormorants

Hirundines etc. noted.
None

Warblers noted (singing birds):
- 3 (3) Chiffchaffs
- 1 (1) Blackcap

Counts from the water:
- 3 + 4 Mute Swans still
- 59 Greylag Geese
- 1 Greylag x Canada Goose still
- 127 Canada Geese
- 24 (11♂) + 5 (2 broods) Mallard
- 7 (7♂) Tufted Ducks
- 2 Grey Herons again
- 2 + 2 (1 brood) Great Crested Grebes
- 2 Moorhens
- 17 + 8 (3 broods) Coots
- 1 Black-headed Gull

The most accessible Riband Wave moth (Idaea aversata) so far and hence my best photo. 

This moth is likely a Little Grey (Eudonia lacustrata). There are, as ever, a number of confusingly similar species though this is by far the most common.

Another presumed Little Grey moth.

A bit of a puzzle when seen some ten feet above me on a lamp pole. I have concluded it is a yet another ladybird pupa, most likely also a Harlequin Ladybird (Harmonia axyridis).

Between the lake and The Flash:

- still no Moorhens noted
- 1 calling Chiffchaff near the upper pool
- 1 (1) Blackcap still at the lower pool
- 2 Bullfinches, one of them a juvenile, around the upper pool
and
- 1 Grey Squirrel
- 1 Small Dusty Wave moth (Idaea seriata) on the tunnel-wall under Priorslee Avenue

A long way away on a dull morning ... I do not often get a chance to photograph juvenile Bullfinches. These look quite different from adults as the body is plain olive-brown and they lack any black on the head. Note here the large grey bill and the broad white bar across the black wing. We also see the broad white rump showing above the tail.

The moth in the Priorslee tunnel was on the wall today. It took me a while to realise that it is not, as I assumed, one of the confusing pug moths but in fact a Small Dusty Wave (Idaea seriata) – a common-enough species that I have not seen for a number of years.
