Priorslee Balancing Lake and The Flash

3.0°C > 5.0°C: Clear skies. Light north-westerly wind. Excellent visibility.

Sunrise: 07:50 GMT

$ = my first sighting of the species for this year
$$ = my first ever recorded sighting of the species in the area

Priorslee Balancing Lake: 06:15 – 09:35

(287th visit of the year)

Bird notes
A distant and high party of 22 Golden Plover were seen to the East at 07:25 identified by their distinctive formation pattern and very fast wingbeats. I record this species most years. The numbers involved seems to reduce year-on-year. It is bird species #106 for me here this year.

Other bird notes:
- a male Pheasant calling again in the south-west area.
- large arrival of gulls started by 06:40 with eventually c.700 Lesser Black-backed and c.250 (very noisy) Black-headed Gulls. Not easy to see at this time but there seemed to be no more than 10 Herring Gulls with them.
- after 08:00 there was a mass arrival from the North of 41 Herring and 210 Lesser Black-backed Gulls.
- a low count of Jackdaws and Rooks passing over from their roost(s). With a northerly component in the breeze and clear skies those I noted were flying very high out of both audible and, without using binoculars, visual range.
- at least 20 Siskins in

Bird(s) noted flying over here:
- 22 $ Golden Plover
- 1 Feral Pigeon
- 21 Wood Pigeons
- 51 Lesser Black-backed Gulls
- 26 Jackdaws
- 25 Rook

Counts from the lake area:
- 9 Canada Geese: arrived as a septet and then a duo
- 10 (7♂) Mallard
- 3 (2♂) Pochard
- 48 (24?♂) Tufted Duck
- 4 Moorhens
- 47 Coots
- 5 Great Crested Grebes
- c.250 Black-headed Gulls
- c.50 Herring Gulls
- c.700 Lesser Black-backed Gulls
- 2 Cormorants: arrived separately
- 1 Grey Heron

Noted on the West end street lamp poles pre-dawn:

Moths:
- 7 Winter Moths Operophtera brumata
- 2 Mottled Umbers Erranis defoliaria

Ants:
- 1 Formica sp., possibly Blood-red Ant F. sanguinea

Beetle:
- 1 flea-beetle

Spiders, harvestmen etc.:
- 1 Long-jawed Orb-web Spider Tetragnatha sp.

Later on the Teece Drive fence or elsewhere:
Nothing noted

No cloud so limited interest to the sunrise.

 It was still before sunrise when this distant Great Crested Grebe caught its breakfast.

A Blue Tit looking for insects wherever. Here on an air-vent on the sailing club's shower and toilet block!

Often a shy species this Redwing was not going to show itself!

What a sweetie. A male Pied Wagtail. Note the back is not universally the same shade of black (if that makes sense!). Possibly a first winter bird?

Yes: you!

A female Siskin tucks in to Alder cones for the seeds.

A male Siskin does the same.

As does this one.

Direct comparison: a female Siskin above a male.

An unusually well-marked specimen of a Winter Moth Operophtera brumata.

One of two Mottled Umbers moths Erranis defoliaria on the street lamp poles. This is a very faintly-marked individual with the wavy cross band and the black dot in each wing only revealed by some judicious editing. The editing also revealed an unidentified flea-beetle is keeping it company. Note the very straight edge along the front two-thirds of the moth's wings.

That straight-edge was important to identifying another faintly-marked individual sitting at a very difficult angle.

At the time I thought this would turn out to be a ground beetle when I looked at the photo in detail. Not so. It is a very large ant. Searching around my usual apps and web sites I am sure it is a Formica sp., and just possibly Blood-red Ant F. sanguinea.

The only spider or harvestman on the poles was this Long-jawed Orb-web Spider Tetragnatha sp.

In the Priorslee Avenue tunnel pre-dawn:

Flies:
- 1 midge only

Spiders, harvestmen etc.:
- 3 spiders: all Missing Sector Orb-web Spiders Zygiella x-notata [Silver-sided Sector Spider]

About time we had a photo of a Missing Sector Orb-web Spider Zygiella x-notata (or Silver-sided Sector Spider if you prefer).

The Flash: 09:40 – 10:50

(280th visit of the year)

Bird notes:
- still very few geese.
- a first-winter Mute Swan cygnet was departing as I arrived.
- no sign of the Little Egret but three Grey Herons.
- a trio of (Common) Teal (two drakes) flew from the top end and was then unusually seen in the open alongside the island.

Bird(s) noted flying over here:
None

Noted on / around the water:
- 6 Canada Geese
- no Greylag Geese
- 26 (17♂) Mallard

Noted around the area:
A few things on the sunlit bank of Ivy despite the low temperature

Moths:
- 1 Winter Moth Operophtera brumata : same as yesterday

Bees, wasps etc.:
- >3 Common Wasps Vespula vulgaris

Hoverflies:
- 1 Marmalade Hoverfly Episyrphus balteatus
- >2 Tapered Droneflies Eristalis pertinax

Other flies:
- >40 Common Blow Fly Calliphora vicina
- >10 smaller unidentified flies

The first-winter Mute Swan cygnet circling to....

...to leave.

Very high contrast on the trio of (Common) Teal at the edge of the island. Two drakes on the left. A Coot is lurking at the extreme right.

A sextet of Pochard. Two ducks on the left with four drakes. Behind is a duck Tufted Duck.

 Still a few Common Wasps Vespula vulgaris around.

Probably my last Marmalade Hoverfly Episyrphus balteatus of the year.

If the weather forecast is correct (a big if!) and it cloudy for the next few days this may be the last opportunity to see any hoverflies. The Ivy is about finished anyway. Here is one of the Tapered Droneflies Eristalis pertinax I noted.

Perhaps a different specimen.

The same one?

 Again. Note the long tongue. However many there were they were all females.

One of very many Common Blow Flies Calliphora vicina

"Plane" of the day. This is an Airbus Helicopters built Eurocopter EC135 T3H Juno HT.1 from 1 FTS (Flying Training School) at RAF Shawbury. It was on a navex (navigation exercise) and passed over Birmingham Airport before over-flying Leicester Airport to reach Preston before returning to base.
