Priorslee Balancing Lake and The Flash

8.0°C > 9.0°C: Surprise! More very low cloud. Brisk easterly wind fell light. Moderate visibility.

Sunrise: 08:20 GMT again

I am pleased to say that all the photos withheld recently have now been added and can be accessed by scrolling down the web page and using the "older posts" link. As always I am hugely indebted to Martin Adlam for his hard work in making this possible.

* = a species photographed today

Priorslee Balancing Lake: 06:45 – 09:35

(310th visit of the year)

Bird notes:
- *six Canada Geese were again on the water at first light, soon leaving to the East. A pair came in from the East later, returning a few minutes later.
- yesterday's two Mute Swan arrivals were nowhere to be seen.
- in the murk I did not count the Coots today.
- Perhaps the lowest number of gulls I can recall. The first eight of an eventual c.75 Black-headed Gulls arrived at 07:43.
- Four Lesser Black-backed Gulls came from the South at 07:47, took a look around and flew off South again. Four more(?) did the same thing a few minutes later. A single adult arrived at 08:15. No others were on the water with just a small number passing over.
- a quartet of Cormorants arrived together. Another arrived later.
- the Great (White) Egret seen again. None of the three Grey Herons seemed interested.
- as yesterday a typical number of Rooks were noted passing on their usual flight-line but very few Jackdaws.
- I only glimpsed it briefly but it seemed a lone Starling flushed off the dam-face c.08:15. Most odd.
- not entirely clear how many Song Thrushes were singing today. Certainly 13 on my first walk around. Later two birds were singing at other locations when most of the original songsters had fallen quiet. New songsters or birds relocating?
- *at least 25 Redwings flushed out of trees around the Telford Sailing Club HQ c.09:15.

Bird(s) noted flying over here:
- 4 Wood Pigeons only
- 1 Herring Gull
- 42 Lesser Black-backed Gulls
- 48 Jackdaws
- 134 Rooks

Counts from the lake area:
- *8 Canada Geese: six departed together; two visited briefly
- 6 (4♂) Mallard
- 28 (18♂) Tufted Duck
- 7 Moorhens
- Coots not counted
- 3 Great Crested Grebes
- c.75 Black-headed Gulls
- no Herring Gulls
- 1 Lesser Black-backed Gull only
- 5 Cormorants: see notes
- *3 Grey Herons
- 1 Great (White) Egret

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

Moths:
- 1 male Mottled Umber Erranis defoliaria: fourth day in the same place

Flies:
- 1 very small plumed midge

Springtails:
- 5 springtails sp., all probably Dicyrtomina saundersi

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

Later:

Nothing seen

Much the same weather as yesterday pre-dawn. Today a group of Canada Geese photo-bomb the view.

My friend the Grey Heron was by the Wesley Brook bridge again.

It looked at me.

Checking me out

And then got down to the serious business of fishing.

Success again! Not sure about the fish species. Obsidentify did not help: "Mountain Hare"!?!

Now the right way around for the heron to swallow. You have feel sorry for the fish but the heron has to eat.

The heron then wandered off, carefully watching me but unperturbed.

One of c.25 Redwings in trees at the West end.

The Flash: 09:40 – 10:50

(303rd visit of the year)

Bird notes:
- a second Mute Swan today. They took very little notice of each other.
- *until yesterday I had not seen or heard any Coal Tits for some weeks. Yesterday there were two singing and calling by the academy. Today three were chasing around alongside the lower car parking area – at least other than for a short break as everything dived for cover when a Sparrowhawk flew over.
- I counted 26 Redwings leaving trees at the top end and flying off East.

Bird(s) noted flying over here:
- 1 Sparrowhawk

Noted on / around the water:
- 7 Canada Geese
- 2 Mute Swans
- 34 (25♂) Mallard [yesterday's total was mistyped as 21 (19♂): it should have read 31 (19♂)]
- *10 (6♂) Pochard: yet again
- 34 (16♂) Tufted Duck
- 2 (0♂) Goosander
- 10 Moorhens
- 43 Coots
- 5 Great Crested Grebes again
- 50 Black-headed Gulls exactly
- 1 Herring Gull: first-winter
- 1 Cormorant
- 2 Grey Herons

Noted around the area:

Spiders, harvestmen etc.:
- *1 Missing Sector Orb-web Spider Zygiella x-notata

There were again no insects on the bank of Ivy.

A drake Pochard again, edited to show the feather patterning to best advantage.

A poor photo of two sparring Coal Tits. The white stripe on their nape is visible – just.

And a very poor photo of the same two.

On one of the street lamp poles I found this spider. Perhaps a Missing Sector Orb-web Spider Zygiella x-notata. But I now read on the NatureSpot site that this species is "very difficult to distinguish from Z. atrica". It seems that around "window frames or car door mirrors" then Z. atrica is unlikely. Elsewhere separation needs an expert – which I am not. So I should probably record these in future as "Missing Sector Orb-web-type Spider from the species pair Zygiella x-notata / atrica".

Priorslee Balancing Lake and The Flash

7.0°C > 8.0°C: More very low cloud. A short spell of rain c.09:15. Moderate easterly wind. Moderate visibility becoming good.

Sunrise: 08:20 GMT

Despite it being the Winter solstice and the shortest day it will continue to get lighter slightly later in the mornings for the next 10 days or so.

Photos will be added later

Priorslee Balancing Lake: 06:50 – 09:30

(309th visit of the year)

Bird notes:
- six Canada Geese were on the water at first light, soon leaving to the East.
- two Mute Swans flew in from the West at 09:00.
- I only managed to find 26 Coots today. It would not be a complete explanation because Coot numbers at The Flash are also well down but I have been wondering whether when the contractors cut some of the reeds back in October the cut stems have blocked access to the birds' roosting sites inside the reeds and they have gone elsewhere.
- a Sunday lie-in for the gulls. Both Black-headed and Lesser Black-backs arrived simultaneously from different directions at 07:40. There were more Black-heads and fewer Black-backs with most of the latter having a quick wash and moving rapidly on.
- unusually there was a larger (re?) arrival of both species (along with a few Herring Gulls) c.09:00.
- Wood Pigeon is a species that will breed at any time of the year given the chance. Nevertheless three birds "singing" while it was still dark at 06:55 was unusual at this date.
- no Great (White) Egret seen here (or at The Flash later).
- a typical number of Rooks were noted passing on their usual flight-line but very few Jackdaws.
- a Blackbird joined in with the 13 singing Song Thrushes.
- I should not have mentioned a recent scarcity of Siskins yesterday. At least 10 birds were in Alders at the West end this morning.

Bird(s) noted flying over here:
- 1 Greylag Goose: flew East pre-dawn
- 22 Wood Pigeons
- 4 Herring Gulls
- 91 Lesser Black-backed Gulls
- 47 Jackdaws
- 122 Rooks
- 5 Redwings: two groups

Counts from the lake area:
- 6 Canada Geese: departed together
- 2 Mute Swans: arrived together
- 2 (1♂) Mallard
- 32 (21♂) Tufted Duck
- 4 Moorhens
- 26 Coots only
- 4 Great Crested Grebes as usual
- c.125 || 193 + 16 on football field Black-headed Gulls
- 7 || 13 Herring Gulls
- 65 || 88 Lesser Black-backed Gulls
- 2 Cormorants: arrived separately
- 2 Grey Herons
- no Great (White) Egret

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

Moths:
- 1 male Mottled Umber Erranis defoliaria: third day in the same place

Flies:
- 4 winter craneflies Trichocera sp.
- 1 very small plumed midge

Beetles:
- 1 unidentified small ground beetle

Springtails:
- 1 springtail Pogonognathellus longicornis

Spiders, harvestmen etc.:
- 2 Long-jawed Orb-web Spiders Tetragnatha sp.
- 1 harvestman Paroligolophus agrestis

Later:
- 1 harvestman Paroligolophus agrestis on a wall of Telford Sailing Clun HQ.

Looking West from the dam with the light pollution from Telford providing a glow. The Ricoh sig providing the only colour. The lake is devoid of birds at this time: the gulls are yet to arrive and the Coots are still hiding in the reeds.

Well it is near Christmas so we must have a Robin.

A small male plumed midge. This one no more than 5mm long. No idea as to the species,

A springtail Pogonognathellus longicornis. Apparently it is not unusual for these to lose part of, or sometimes all, one antenna.

One of very many (about 350 if Google AI is to believed) species of ground-beetles in the UK. This was smaller than many and about all I can say.

One of two harvestmen Paroligolophus agrestis I noted this morning. This, on one of the street lamp poles, shows only an ill-defined pale stripe down the abdomen. I asked Obsidentify what it thought. It said Nursery Web Spider Pisaura mirabilis. I have no idea why it thought that. Even if I had got the species wrong it is most certainly a harvestman and not a spider as it has no cephalothorax (the joined head and thorax that are distinct from the abdomen on spiders).

The other Paroligolophus agrestis, this one on a wall of the Telford Sailing Club HQ. The pale stripe down the abdomen is more obvious on this specimen.

------------------------------------------------------------------------------------------------------

Woodhouse area

I made a short visit here, mainly to look at the two storm pools to see whether the Mallard were still hanging out there. Despite both pools having very brown and discoloured water I found:
on the lower pool:
- 25 (17♂) Mallard
- 1 Coot
on the upper pool:
- 2 (1♂) Mallard

The only other birds of interest in the area were:
- a Mistle Thrush was giving its rattling call from a tree near the Priorslee Lake sluice exit (it later flew across Castle Farm Way and started to sing in the south-east area: and was presumably a different bird to one calling alongside Teece Drive much later)
- a Meadow Pipit was heard to flush from the grass. A species that has been scarce this year.

(Ed Wilson)

------------------------------------------------------------------------------------------------------

The Flash: 09:35 – 10:45

(302nd visit of the year)

Bird notes:
- no sign of the drake Shoveler.
- a fifth Great Crested Grebe noted

Bird(s) noted flying over here:
- 3 Herring Gulls
- 1 Lesser Black-backed Gull
- 1 Redwing

Noted on / around the water:
- 7 Canada Geese
- 1 Mute Swan
- 21 (19♂) Mallard
- 10 (6♂) Pochard: again
- 23 (19♂) Tufted Duck
- 3 (1♂) Goosander
- 14 Moorhens
- 46 Coots
- 5 Great Crested Grebes
- 71 Black-headed Gulls
- 3 Herring Gulls: two (near?) adults; one first-winter
- 2 Cormorants
- 2 Grey Herons, the second seen arriving
- no Great (White) Egret

Noted around the area:

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

Beetles:
- 1 pupa of a Harlequin Ladybird Harmonia axyridis

Fungus:
- Blushing Bracket Daedaleopsis confragosa
- Velvet Shank Flammulina velutipes

Unsurprisingly there again were no insects on the bank of Ivy.

An odd-looking duck Mallard, slightly more rufous than usual and with the feathering less well-defined. I am amazed at how many slightly unusual Mallard have turned up over the years, often not staying very long. It suggests that there is more of a movement in and out of this apparently sedentary species than might be expected.

This duck Mallard is more or less dead-centre of this feeding frenzy.

Six of the Pochard went for a fly-about. Of the centre four the leader and the one at the top are clearly adult drakes with paler wings.

Two as they fly back the other way. I cannot explain why the tail feathers are being held differently.

I classified this as a (near) adult Herring Gull. There seems to be too much dark on its bill for an adult-winter yet there is no sign of any remnant dark in the tail. Third- or fourth-winter I suggest.

There were four Song Thrushes singing away here. This one decided that tossing leaves around looking for food was a more worthwhile pursuit.

A Christmas Robin here too.

Unexpected at this date is a pupa of a Harlequin Ladybird Harmonia axyridis. Whether there is anyone home is impossible to say. It looks "fresh".

I found two species of fungus today - seems a bit late in the year. This is Blushing Bracket Daedaleopsis confragosa.

It is fortunate that the Priorslee Academy is not in session. Poking my camera through the fence might be misconstrued even if I was only photographing the Velvet Shank fungus Flammulina velutipes .

Here showing the underside.

Worth another view from a slightly different angle.

Priorslee Balancing Lake and The Flash

4.0°C > 5.0°C:  Very low cloud and mist. Moderate south-easterly wind. Poor visibility, moderate at times.

Sunrise:  08:19 GMT

Well that wasn't as forecast – when is it though? All my weather apps said clear skies. So why was it very misty and then low cloud?

Photos will be added later

Priorslee Balancing Lake: 06:35 – 09:30

(308th visit of the year)

Bird notes:
- usually there are c.12 Coots scattered around the edges at the East end and c.30 at the West end with most of these on the south-west grass. Today 22 appeared on the water at the East end with only 15 on the south-west grass. I doubt they had been flushed off the grass as there were two Cormorants on the sailing club platforms and I am sure they would have moved off had there been any disturbance.
- the first Black-headed Gull arrived at 07:48. Eventually c.50.
- 22 Lesser Black-backs appeared out of the murk overhead at 07:31 and disappeared again. 34 did the same at 07:37. I am assuming these were among the eventual c.375 that were present by 08:05.
- a Great (White) Egret again. Neither of the Grey Herons flushed it away. It was therefore not seen at The Flash later.
- only a few Jackdaws and Rooks were visible overhead.
- a group of 10 Greenfinches eating Ash keys at the West end was good to see. A much-declined species. I recall 20+ years ago seeing >400 birds leaving a Winter roost in the south-west area.
- after several weeks when Siskins were heard and usually seen daily I have not recorded any here for the last three days.

Bird(s) noted flying over here:
- 4 Wood Pigeons
- 19 Lesser Black-backed Gulls
- 17 Jackdaws
- 20 Rooks
- 5 Redwings together

Counts from the lake area:
- 5 (3♂) Mallard
- 44 (27♂) Tufted Duck
- 6 Moorhens
- 37 Coots
- 4 Great Crested Grebes as usual
- c.50 Black-headed Gulls
- 24 Herring Gulls
- c.375 Lesser Black-backed Gulls
- 3 Cormorants: not seen to arrive
- 2 Grey Herons
- 1 Great (White) Egret

Noted on the West end street lamp poles pre-dawn:
Colder and with dew on the poles meant very little seen.

Moths:
- 1 female Winter Moth Operophtera brumata
- 1 male Mottled Umber Erranis defoliaria : same as yesterday

Springtails:
- 1 springtail sp., probably Dicyrtomina saundersi
- 1 springtail Pogonognathellus longicornis-type

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

Nothing else

On the Teece Drive fence:

Nothing noted

As I was approaching the Wesley Brook bridge this Grey Heron was standing next to the bridge.

We looked at each other for a while.

The heron decided I was harmless and went on a...

 ...fishing expedition.

  Success!

"Now what do I do with it?"

"I can't swallow it sideways".

Well the head is going down.

Gulp!

Not easy to see – but this female Winter Moth Operophtera brumata doesn't need to be. She attracts her suitors with pheromones. Like many "Winter moth" species the females are flightless with only vestigial wings, thought to be so that she can concentrate all her energy in egg production at this challenging time of the year.

Yesterday's male Mottled Umber Erranis defoliaria with added Xmas sparkle courtesy of the dew.

 A springtail Pogonognathellus longicornis.

The Flash: 09:35 – 10:55

(301st visit of the year)

Bird notes:
- what I assume is the same drake Shoveler was flushed from sedges and then went in to hiding again.
- still 10 Pochard but today I was sure there were six adult drakes.

Bird(s) noted flying over here:
- 7 Lesser Black-backed Gulls

Noted on / around the water:
- 5 Canada Geese
- 1 Mute Swan still
- 1 (1♂) Shoveler
- 40 (26♂) Mallard
- 10 (6♂) Pochard: see notes
- 34 (16♂) Tufted Duck
- 7 (3♂) Goosander
- 7 Moorhens again
- 44 Coots
- 4 Great Crested Grebes still
- 53 Black-headed Gulls
- 1 Herring Gull: (near?) adult, briefly
- no Cormorants
- 1 Grey Heron seen arriving
- no Great (White) Egret

Noted around the area:

Spiders, harvestmen etc.:
- 1 harvestman from the species pair Dicranopalpus ramosus / D. caudatus

Unsurprisingly there were no insects on the bank of Ivy.

The flat-light provided ideal conditions to photograph the Tufted Ducks that had come close to the Derwent Drive fencing to dive for seed proffered, Here a duck looks at me suspiciously.

Yes: you!

Note even ducks (females) of this species always show a small "tuft"

 And a drake in full breeding plumage It is difficult to recall August-time when sexing these birds was difficult as they went through their annual moult.

Six of the seven Goosanders were behaving as pairs. The other brownhead was wandering around elsewhere.

These two Great Crested Grebes had just been displaying. They do not have any real head plumes as yet but what they do have are being raised punk style.

Photographers are often unhappy. A Long-tailed Tit horribly back-lit.

And now with branches in the way.
