Priorslee Balancing Lake and The Flash

13.0°C > 15.0°C: Some patches of cloud. Moderate / fresh north-westerly breeze. Excellent visibility.

Sunrise: 05:13 BST

* = a species photographed today
! = a new species for me here this year
!! = a new species for me in Shropshire

Priorslee Balancing Lake: 04:45 – 06:00 // 07:05 – 09:30

(158th visit of the year)

Bird notes:
- all four Mute Swans remain.
- at 05:45 there were 34 Black-headed Gulls on the academy roof along with 32 more on the football field where there were also nine Lesser Black-backed Gulls and one Herring Gull. At this point something spooked them and they all flew off. By 05:55 a few Black-headed Gulls had started to return(?) with seven of the first 11 being juveniles – suggesting a much more successful breeding season. Last year this species suffered badly from avian influenza.
- five adult Great Crested Grebes were noted: also the juvenile.

Counts of birds noted flying over:
- 7 Canada Geese: single and quartet outbound; single inbound
- 9 Greylag Geese: single outbound; eight flew South to the East together

The (slightly edited) sunrise according my big Sony camera.

A (slightly less edited) sunrise according to my ancient Samsung smart phone. The phone's camera seems to handle the contrast between the bright sky and the shaded vegetation better. It also has an even wider angle of view - the Sony photo was at 24mm equivalent (for those who know about these things).

A Blackcap in hiding. There does not seem to be any gape-line so this is likely an adult female rather than a juvenile.

Of course you remember that Gatekeeper butterflies Pyronia tithonus have two white spots in the black wing dot. Er? This one doesn't!

From above the veins of Green-veined White butterflies Pieris napi are not all obvious. Separation from other 'white' butterflies can be made on the shape of the black wing-tip mark. With a black dot only in each forewing this is a male.

From underneath the veins are very obvious. But 'green-veined' requires some imagination.

A faded Shaded Broad-bar moth Scotopteryx chenopodiata.

The abdomen shape of male Tapered Droneflies Eristalis pertinax is diagnostic.

This is a female (her eyes do not meet) with a less-obviously tapered abdomen.. It is more tricky to separate these from female Common Droneflies Eristalis tenax.

Here is a Common Dronefly Eristalis tenax, separable at this angle by having mainly dark front legs. This was the only insect I noted in the c.100 flowers of Greater Bindweed Convolvulus sylvaticus.

A Chequered Hoverfly Melanostoma scalare. It certainly lives up to the "long-winged" part of its alternative moniker Long-winged Duskyface. The "Duskyface" part is less obvious.

This used to be a cranefly before it became breakfast. One of the 'tiger craneflies'. I cannot identify which on this view.

The only thing I could find on the street lamp poles around dawn was this springtail Pogonognathellus longicornis-type. A better photo than many – the hairs on the side of the abdomen are visible.

In the Priorslee Avenue tunnel:

Moths:
- *1 Single-dotted Wave Idaea dimidiata

Nothing else noted

The best specimen of a Single-dotted Wave moth Idaea dimidiata I have found so far this year. And no: I don't know why it is "single-dotted".

The Flash: 06:05 – 07:00

(161st visit of the year)

Bird notes:
- I noted the duck Gadwall again. I suspect she is always around somewhere: not easy to find with all the Mallard in eclipse (non-breeding) plumage.

Bird(s) noted flying over here:
None

Hirundines etc. noted:
- 6 Swifts
- 3 House Martins

Warblers noted (the figure in brackets relates to birds heard singing):
- 4 (0) Chiffchaffs
- 1 (1) Blackcap
'nominal' warbler
:
- no Goldcrests

Noted on / around the water:
- 179 Canada Geese
- 24 Greylag Geese
- 1 Canada x Greylag Goose
- 2 + 3 (1 brood) Mute Swan
- 1 (0♂) Gadwall
- 14 (?♂) Mallard
- 23 (?♂) Tufted Duck
- 7 + 6 (4 broods) Moorhens: two of the broods new
- 56 + 2 (2 broods) Coots
- 3 Great Crested Grebes

Noted elsewhere around The Flash:

Moths:
- *1 !White-banded Grass-moth Crambus pascuella [Inlaid Grass-veneer]
- *1 Engrailed Ectropis crepuscularia

Typically a long way up a street pole was this fresh-looking White-banded Grass-moth Crambus pascuella. This species used to be known as Inlaid Grass-veneer. The new name seems better.

Not so fresh-looking was this Engrailed moth Ectropis crepuscularia
