Priorslee Balancing Lake and The Flash

11.0°C > 15.0°C: Mostly cloudy at medium level. A few blue patches but also some light showery rain c.08:45. Light south-westerly breeze. Very good visibility.

Sunrise: 07:00 GMT

* = a species photographed today.

Priorslee Balancing Lake: 05:40 – 08:55

(230th visit of the year)

Bird notes
Highlight this morning was only my second Peregrine of the year here (the previous one was on 14 June). It cruised over c.06:45. Remarkably none of the many gulls on the water paid it any heed with a single passing Jackdaw attempting to chase it away.

Other bird notes:
- only small groups of migrant Wood Pigeons noted and these did not all seem clear as to where to go. One group was flying West; two south-west and one south-east with other three groups heading South.
- after the now usual arrival of at least 450 Black-headed Gulls, skimming in low over the M54 at 06:35. I was then surprised to see two more large groups (c.100 and c.150) arrive a few minutes later.
- in contrast there were very few large gulls, especially early. The first three appeared overhead at 06:30 but deigned to stop and these, along with 18 others, flew on. Eventually just seven Lesser Black-backs arrived before almost all the gulls departed.
- much later 49 Lesser Black-backed Gulls flew in from the North, followed ten minutes later by 11 Herring Gulls. Most odd.

Counts of birds noted flying over:
- 11 Canada Geese: four outbound together; seven inbound in two groups
- 2 Greylag Geese: outbound together

Telford Sailing Club
Around the outside of the Telford Sailing Club HQ pre-dawn:

Flies:
- 4 craneflies, not all specifically identified: one could be *Nigrotipula nigra
- 9 other midges/gnats, also not specifically identified

Beetles:
- 1 Alder Leaf Beetle Agelastica alni

Spiders, harvestmen etc.:
- 23 spiders of several species, not specifically identified
- 1 male harvestman Leiobunum rotundum

Noted later:

Bees, wasps etc.:
- 1 Common Wasp Paravespula vulgaris

Plants:
- *Nipplewort Lapsana communis: seem unusually late for this to still be flowering

Surprisingly somewhat better weather than I expected – until it rained a bit later.

A Great Crested Grebe in winter plumage. Just a few vestigial head plumes remain – or perhaps are beginning to regrow.

Record shot of the Peregrine. Well it was only 06:45!

A cranefly that was flying against a wall of the Telford Sailing Club HQ. I pressed the shutter at just the right moment to capture the distinctive wing markings that leads to its identity as – er? I cannot find a match. It might be Nigrotipula nigra which would be a new species for me.

I saw two craneflies in a similar pose as few days ago. At the time I noted that all the mating pairs I have seen in photos have been with them paired end-to-end. There were two 'pairs' like this today where the upper individual was sitting at a slight angle and lower individual had no abdomen showing. So I suspect they are mating with one of them twisting their body upwards somewhat similar to female damselflies.

Two unidentifieds. At the top a small ichneumon. At the bottom at springtail.

Another unidentified tiny insect. As far as I can tell it is most likely one of the Psylliodes - jumping plant lice. The few that are illustrated on the NatureSpot web site which vaguely match this are all seen during Summer.

A Long-jawed Orb-web Spider Tetragnatha sp.

Both my apps were convinced this is Nipplewort Lapsana communis. Not only does it seem unusually late for this to be flowering but I am used to seeing at the top of vertical stems.

The Flash: 09:00 – 10:30

(233rd visit of the year)

Bird notes:
- a Little Grebe again. Is it the same one? Has it been lurking by the island all the while? It was today. I heard it call once – unusual outside the breeding season I would have thought.

Bird(s) noted flying over here:
- 3 Jackdaws
- 23 Redwings: two groups

Noted on / around the water:
- 5 Canada Geese
- 3 Greylag Geese
- 6 + 3 (1 brood) Mute Swans
- 36 (24♂) Mallard
- *1 (1♂) Mallard-hybrid
- 131 (?♂) Tufted Duck
- 16 Moorhens
- *136 Coots
- *1 Little Grebe
- 1 Great Crested Grebe
- 2 Black-headed Gulls
- 1 Cormorant

Noted around The Flash:

Moths:
- *1 Pale Birch Tortrix Acleris logiana.: almost the same place as yesterday

Bees, wasps etc.:
- >5 Common Wasps Paravespula vulgaris

Flies:
- *1 possible Nettle Aphid Microlophium carnosum
- at least five species seen

Leafhoppers:
- *1 unidentified leafhopper

Bugs:
- *1 Harlequin Ladybird Harmonia axyridis var. succinea

Beetles:
- 1 Alder Leaf Beetle Agelastica alni

Spiders, harvestmen etc.:
- none

A few more photos of this strange Mallard-hybrid. I cannot think of any species of duck whose drakes shows feathering along the flanks as shown here. And where does the rufous on the face come from?

The bill pattern is a puzzle too.

The curled tail-feather confirms drake Mallard genes are there.

Coots are inveterate nest-builders. This one is still building.

When not nest building they can often be found fighting. Two against one here.

"Take that".

Reinforcements arrive.

Apparently surrenders. It is interesting that with c.140 Coot here at the moment many of them are not fighting – thank goodness.

As previously noted it is a long way to the island and Little Grebes are indeed 'little'.

Of course at the top of a tree behind many branches. A Great Spotted Woodpecker.

With red on the nape it is a male.

The same Pale Birch Tortrix Acleris logiana had moved a few inches to the right and was hiding in a crack in the street lamp pole. Even had I initially noticed it here the view would almost certainly precluded identification.

A number of unidentified flies today. Here is one.

 And another.

This looks distinctive-enough to be easy to identify. Looks can be deceptive! In real life it was stunningly orange-toned and resembled some other small orange flies. The banding on the abdomen is something I have not seen previously.

Another settling down to a meal of Ivy nectar.

An unidentified leafhopper. Some species are distinctive-enough to be identified from reasonable photos. There are several confusing mainly green ones.

Another puzzle. The 'lump' looks to be what I identified last week as the workings of the gall-midge Dasineura urticae. Here a small nymph seems to be emerging from the gall. A midge would not have a nymph-stage: like all flies their lifecycle is egg then larva and direct to adult. Perhaps the 'nymph' is a Nettle Aphid Microlophium carnosum and unconnected with the gall.

At last. Something I can identify! A Harlequin Ladybird Harmonia axyridis of the form succinea. All forms are somewhat variable. This is unusual in showing more black than red (the spots are larger): also the dark shading in the white 'eyes' does not appear in any photos I can find on the internet.
