Priorslee Lake: 10:00 – 10:10

(246th visit of the year)

A very short visit viewing from the dam area to check whether there was anything unusual: there wasn't. The sailing club were setting up and some things had probably departed.

Bird notes:
- The loud Cetti's Warbler was heard, relocated in the NE area.

Overhead:

- 12 Black-headed Gulls only
- 1 Herring Gulls
- 14 Lesser Black-backed Gulls

Nothing else noted

(Ed Wilson)

Note:
If you happen to be at Priorslee Lake and hear a really loud burst of song, it could be the Cetti's Warbler.

Here is a short video of a Cetti's Warbler I recorded at Radipole Lake, Weymouth a few years back. There is a long intro and then the song. (Martin Adlam - Port and Wey)

And a photo of the Cetti's Warbler (Martin Adlam)

Another rain-delayed start.

Priorslee Lake: 08:35 – 10:10

(245th visit of the year)

I had hoped that as the weather cleared there might be some visible migration. Not so – apart from two small groups of Wood Pigeons.

I only viewed from the dam area.

Bird notes:
- The loud Cetti's Warbler was heard, relocated in the NE area.

Overhead:
- 4 Greylag Geese: one group, inbound
- 1 (♂?) Goosander
- 4 Stock Doves: two duos flying S.
- 42 Wood Pigeons: 18 of these in two migrant groups heading S
- 1 Herring Gull
- 24 Lesser Black-backed Gulls
- 2 Common Buzzards
- 1 Redwing

Counts from the lake area:
- 2 Mute Swans: 7JVC + unringed
- 3 (2♂) Mallard: arrived
- 2 (1♂) Gadwall
- no Pochard located
- 42 (22♂) Tufted Duck
- 2 Moorhens
- 66 Coots
- 1 Little Grebe
- 46 Black-headed Gulls only
- 5 Herring Gulls
- 13 Lesser Black-backed Gulls
- 2 Cormorants: arrived separately

Also noted
- 1 Cetti's' Warbler – heard from NE area
- 1 Grey Squirrel
- *a different species of fungus, probably Butter Waxcap (Hygrocybe ceracea).

I think this fungus is Butter Waxcap (Hygrocybe ceracea). It looked rather too delicate to go rooting about 'gardening' so as to get a view that included the stem.

(Ed Wilson)

The Flash: 10:15 – 11:10

(222nd visit of the year)

Bird notes:
- One of fishermen reported that seven Goosanders had briefly dropped in.
- A Redwing in Hawthorns near the Priorslee Academy

Birds noted flying over here:
- 1 Feral Pigeon

On /around the water:
- 26 Canada Geese
- 4 Greylag Geese
- 3 + 2 (1 brood) Mute Swan
- 26 (17♂) Mallard
- 19 (5♂) Tufted Duck
- no Goosander: see notes
- 9 Moorhens
- 23 Coots
- 4 Great Crested Grebes again
- 12 Black-headed Gulls
- 1 Grey Heron again

On one of the lamp poles:
- *Hawthorn Shieldbug (Acanthosoma haemorrhoidale)

Noted elsewhere:
- very many Common Wasps (Paravespula vulgaris) on the Ivy flowers.
- *Marmalade Hoverfly (Episyrphus balteatus)
- *Common Drone Fly (Eristalis tenax)
- *Chequered Hoverfly (Melanostoma scalare)
- *Syrphus sp., possibly Glass-winged Syrphus (S. vitripennis)

It is all insects today before they all disappear. On sunny days we may get hoverflies on the bank of Ivy by the academy in to December is the wasps don't eat all the nectar first. I found four species of hoverfly this morning though mostly singes of each species. Even from the side this Marmalade Hoverfly (Episyrphus balteatus) is easy-enough to identify with paired striped on the abdomen.

Here a plan view showing those stripes. Also noticeable are the three stripes down the thorax. These stripes slightly spread apart.

When they sit still and I can get a really sharp photo I am always surprised how hairy hoverflies are. This is the most common species in late Autumn, a Common Drone Fly (Eristalis tenax). On this species the front legs are mainly dark.

A different specimen with its tongue stuck in to an Ivy flower.

And a third specimen. This view also highlights its hairiness.

Surprisingly my first Chequered Hoverfly (Melanostoma scalare) of the year here – possibly the last also. It is just possible to make out the yellow spots on the abdomen through the folded wings. It is also just possible to see these are triangular marks indicating it is a female, though the widely separated eyes is a somewhat easier way to sex this specimen.

The fourth species of hoverfly, one of the Syrphus ribesii / S. vitripennis pair. A male which are usually regarded as inseparable unless examined under a microscope. Reference to the latest information on Steven Falck's Flickr site suggests that with very restricted yellow on the hind femur this is S. vitripennis which he calls Glass-winged Syrphus.

A sunny Hawthorn Shieldbug (Acanthosoma haemorrhoidale). Some idea of the actual size of this insect can be gauged by looking at what it is resting on. That is the edge of the wrap-around to a lamp pole in squirrel alley. Sometimes I find insects tucked in to the cracks on these lamp poles.

Lastly a bit of a cheat. Taken on a window-sill of my house before it ran away and hid. It is a Harlequin Ladybird (Harmonia axyridis) of the less-often seen form spectabilis (as far as I recall my first this year).

Priorslee Lake: 11:05 – 12:05

(244th visit of the year)

A later visit with all viewing from the dam-top area only.

Firstly an update on the Mute Swans:
Courtesy of Martin Grant, keeper of the ring information:
- Three of the four cygnets raised this year were ringed. The one I had not recorded was 7JVL. This is presumably what I have referred to as the fourth cygnet and which I did not see after it was ringed. It had been noted flying strongly, often on its own, by that date.
- Of the two recent arrivals 7JVC is a pen (female) hatched in May 2020 at The Hem near Shifnal. In early September this year it was noted with at least 22 other Shropshire-ringed birds in a flock of c.120 swans near Bangor in North Wales.
- Nothing is known about the unringed bird, though the assumption is that it is a cob (male).

Bird notes:
- All the large gulls were 'passing through', stopping for a wash and brush up.

Overhead:
- 3 Common Buzzards
- 35 Starlings: two groups
Wood Pigeons not counted: very few

Count from the lake area:
- 2 Mute Swans
- 2 (1♂) Mallard
- 3 (2♂) Gadwall again
- 1 (0♂) Pochard still
- 40 (14♂) Tufted Duck
- 1 Moorhen
- 61 Coots
- 17 Black-headed Gulls only
- 6 Herring Gulls
- *71 Lesser Black-backed Gulls
- 1 Kingfisher

I paused over this first-winter gull with a white-looking head. It is 'just' a Lesser Black-backed Gull as evidenced by the dark primaries and secondaries with the greater coverts almost as dark. There is no suggestion of the inner primaries being paler apart from small white fringes. Note that the bill has a tiny pale tip. Note too the broad dark tail with only a hint of pale on the outer edge of each outermost feather.

(Ed Wilson)

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

The Flash: 09:55 – 10:55

(221st visit of the year)

A bit windy and some things likely to be hiding away.

Bird notes:
- No Teal found.
- Goosanders back with at least three drakes.

Birds noted flying over here:
- 1 Sparrowhawk
- 2 Jackdaws

On /around the water:
- 20 Canada Geese
- 1 Greylag Goose
- 3 + 2 (1 brood) Mute Swan
- 29 (20♂) Mallard
- no Teal
- 16 (6♂) Tufted Duck
- *10 (3♂) Goosander
- 3 Moorhens only
- 22 Coots
- 4 Great Crested Grebes
- 13 Black-headed Gulls
- 1 Grey Herons

On the lamp poles:
Nothing on any of them

Noted elsewhere:
- Common Wasps (Paravespula vulgaris) on the Ivy flowers.
- *Several flies, all perhaps Phaonia errans.
- *1 planthopper, most likely Empoasca vitis

The resident pair of Mute Swans. When they can be compared this closely it is possible to say the back bird is the cob (male). He is slightly bigger and the swelling at the base of the bill is larger. When a bird is seen on its own neither of these features is necessarily obvious. Martin Grant provides information that I have been telling people incorrectly. The pen (female) has the green ring – CF59. Green rings are put on birds in Cheshire and not Worcestershire as I have reported. Oops!

A trio of drake Goosanders was among a small group of ten birds. Here is one. Still to acquire full plumage with some white showing at the base of the bill and the flanks still with some grey areas.

Two drakes and three brownheads (and an adult Black-headed Gull).

Ostensibly two brownheads (again with an adult Black-headed Gull). The front bird has too much white showing in the wing as it preens and the breast is too pale for a duck; it is a drake beginning its moult in to adult plumage. Indeed the head is not really 'brown' and beginning to 'go green'.

In addition to many Common Wasps (Paravespula vulgaris) on the Ivy flowers there were a few of these flies. I am never sure how they manage to hold on when the leaves they are sitting on are blowing about. They must have very sticky feet. This individual has spiky hairs which suggests it is a species of House Fly of the Muscidae family. If I had to guess I would go for Phaonia errans as the species.

I also found this planthopper, most likely Empoasca vitis. There are similar species: however the pale oval area on what appears to be the flanks suggests this species. This species is active throughout the year when the temperature is warm enough. I think the brown leaf mine alongside it is unrelated. The planthopper did not behave as if it had just emerged, springing far away as I tried to get a closer shot.

Priorslee Lake and The Flash

13.0°C > 14.0°C: Mostly cloudy once more. Light drizzle c.08:00. Fresh / strong S wind. Very mild again. Very good visibility.

Sunrise: 07:58 BST

Priorslee Lake: 06:25 – 09:25

(243rd visit of the year)

Rather quiet on the lake. I wonder whether the construction work across Castle Farm Way is having an effect. Earth-moving equipment has created a large mound of soil which is being added to from c.07:15 by vehicles with very powerful lights. These shine across much of the lake. Next week, after the clocks have changed, work will not start until after day-break for a few weeks at least.

Other bird notes:
- I was correct when I suspected the two Mute Swans might not be 'our' pair. One has blue Darvic ring 7JVC; the other has neither a Darvic plastic nor BTO metal ring.
- Only one pair of Gadwall seen. Still an extra drake.
- Five Black-headed Gulls arrived at 07:20 but did not stay. No more until c.20 at 07:35 with eventually a rush of over 150 arriving together at 07:45.
- This morning's early 'large gull' count: 11 Lesser Black-backed Gulls and one Herring Gull stopped off; and 39 unidentified gulls flew over.
- As I was trying to count the first big group of >80 Jackdaws passing over the E end of the lake at least 80 Starlings shot out of the reeds at that end and mingled with them.
- A lone Reed Bunting was the only other bird noted leaving a roost around the water.

Overhead:
- 27 Wood Pigeons: no migrant groups
- 48 Lesser Black-backed Gulls
- 39 unidentified large gulls only
- 1 Common Buzzard again
- >200 Jackdaws
- 1 Rook
- c.20 Pied Wagtails
- 1 Siskin

Warblers noted:
- 1 Cetti's Warbler: sang at least five times in the NW area

Count from the lake area:
- *2 Mute Swans [yesterday's total should have read 2 also]
- 2 (1♂) Mallard: departed
- 3 (2♂) Gadwall [yesterday's total should have read 5 (3♂)]
- *1 (0♂) Pochard again
- 42 (>21♂) Tufted Duck
- no Moorhens seen or heard: most unusual
- 52 Coots
- 1 Little Grebe
- c.175 Black-headed Gulls
- 4 Herring Gulls
- 27 Lesser Black-backed Gulls
- 1 Grey Heron: departed

At / around the street lamps pre-dawn:
Draughty again!

Moths:
- 2 November Moth agg. (Epirrita sp.)
with:
- several more small flies
- *possible Pegomya bicolor
- *Phaonia pallida
- *unidentified
- *1 ichneumon sp.
- 2 Common European Earwig (Forficula dentata)
- 2 Pogonognathellus longicornis-type springtail
- *1 possible Iris Leaf Beetle (Aphthona nonstriata)
- 1 Larinioides cornutus (Orb-web spider)
- 1 Bridge Orb-web Spider (Larinioides sclopetarius)

Feedback via Martin Adlam from the Diptera Facebook group suggests from yesterday

- the small fly with the startlingly red eyes is probably a species of Drosophila fly. This group are called small fruit, wine or vinegar flies. One member, D. melanogaster is widely used in science. It seems that the genes of these flies and of humans are so closely related (!) the flies can be used in genetic research.

- the larger fly with red eyes and red-brown head and thorax is almost certainly Dryomyza anilis.

Wikipedia will provide more details than you could ever wish to know about these critters.

Noted later:
- 2 more species of fungus
- - *probable Hare's-foot Inkcap (Coprinopsis lagopus)
- *Beefsteak Fungus (Fistulina hepatica)

Some Autumn colour. The leaves were rapidly falling in the strong wind.

The magic camera just about froze the movement of the leg on this Mute Swan to enable the Darvic ring to be read – 7JVC.

I managed a reasonable photo of the Pochard. Although it looks superficially like a duck Pochard the back looks rather blotchy and the pale mark behind the eye is rather indistinct. I suspect it might be an immature yet to moult in to adult plumage, though I would think it will become a duck anyway.

One of a three different small flies this morning, this with a grey thorax and red abdomen. It may be a Pegomya bicolor though the photos of that species on the web do not seem to have the dark bands across the abdomen.

This is almost certainly one of the more common small flies, though slightly larger than some. I think Phaonia pallida.

Here is another small fly, this with rather dull red eyes and a striped grey / black thorax. I cannot track down any identity for it.

I probably saw the species yesterday though I fouled up the photo. It looks to be a species of ichneumon – the 'wasp-waist' can just be made out. Unlike species I have seen before this appears to have a mark in the wing.

A tiny black beetle found on a lamp pole. It is possible it is an Iris Leaf Beetle (Aphthona nonstriata), a species associated with Yellow Flag Iris which occurs here. But there are many species of small beetle.

 I think this is a Beefsteak Fungus (Fistulina hepatica) on a tree that is broken off just above head height.

Another fine clump of fungus.

A closer view of one of them. I am sure this one of the Coprinus group, known colloquially as Inkcaps.

One small one still growing showing their original shape. The group most closely resembles Coprinopsis lagopus, known as the Hare's-foot Inkcap from the supposed resemblance of the young fruiting bodies to the foot of a Hare. While not being entirely familiar with the Hare's anatomy this one does not look like the foot of anything. [Confused of Newport: the scientific name for the Hare family is Lepus. It is the Grouse family that is Lagopus. So why not C. lepus?]

I tried to get a shot of the underside. I could find no angle that was not against the sky and even forcing the flash to fire failed to provide the detail I hoped for. The fruits of this species are very short-lived – they deliquesce in a matter of hours. The underground mycelium live for many years.

Priorslee Lake: 06:20 – 09:30

(242nd visit of the year)

Still quiet. Best was a high-flying Great White Egret going W at 08:30. By the time I had put the appropriate settings on the camera for what would have been, at best, a record shot I could relocate it.

Other bird notes:
- Two adult Mute Swans. I was not able to read any rings and I have mixed views as to whether they are 'our' pair. Once they awoke they positioned on the slipway suggesting they were 'ours'. However the bill colour of both of them looked rather paler than I recall. Time may tell.
- A second pair of Gadwall new in. Still an extra drake.
- First returning Pochard of the Winter – a duck.
- Tufted Duck especially tricky to count as many were being harassed by Black-headed Gulls and continually diving right at the edge of the water in the vegetation. Probably under recorded.
- After several days with rather few Black-headed Gulls a group of at least 250 arrived well before dawn at 07:15 and flew around and around for at least 20 minutes. They must have better eye-sight and quicker reactions than me to avoid crashing in to each other, though perhaps from inside the group it looks more organised than it does looking across at birds going in all directions.
- Rather more 'large gulls' with 26 Lesser Black-backed Gulls and eight Herring Gulls stopping off; and 21 unidentified gulls flying over.
- c.20 Starlings glimpsed probably leaving a roost in the W end reeds.

Overhead:
- 16 Wood Pigeons only: no migrant groups

Moths:
- 1 November Moth agg. (Epirrita sp.)
with:
- *many small flies
- *2 craneflies: different species
- 1 male Plumed midge (Chironomus plumosus)
- 1 froghopper sp.
- 4 Common European Earwig (Forficula dentata)
- 1 Common Rough Woodlouse (Porcellio scaber)
- 1 Pogonognathellus longicornis-type springtail

- 1 Paroligolophus agrestis harvestman

In the sailing club shelter pre-dawn
- *1 (Common) Striped Woodlouse (Philoscia muscorum)
- many Bridge Orb-web Spiders (Larinioides sclopetarius) as usual

Nothing of note later:

'Tis the Fall. With a fresh wind to blow the leaves down and the academy on half-term (and no teachers or workmen today) there was no traffic to blow the leaves off Teece Drive (and block the drains).

I am afraid it is all 'creepies' this morning. A small fly with startlingly red eyes and short body (or long wings if you prefer). Despite (because of?) the wind there were more flies than usual and less of everything else.

A slightly larger fly with a red head and thorax as well as red eyes. Anyone know a dipterist in Shropshire to help?

A large plain-looking cranefly with one of its long legs missing. Possibly Tipula luteipennis but I am far from certain.

I found this rather different-looking woodlouse in the sailing club shelter. It is unsurprisingly called a (Common) Striped Woodlouse (Philoscia muscorum). There is another species of woodlouse that also has a black stripe along the back but that has prominent yellow blotches at the edge of the stripe. As far as I can tell a new species for me. How exciting!?

The daily spider. I thought the dark band across the carapace and the head meant it was a Neriene peltata. I read that species has unmarked legs which this hasn't. Over to Nigel – I was close: it is N. montana.

Council contractor were out massacring some of the hedges today cutting off the berry crop that the winter thrushes might like. Perhaps the contractors will do some of the bushes that overhang the paths later. Perhaps.

Bird notes:
- Just the drake Teal found.
- Why so few Tufted Duck? Usually there are >50 at this time of year.
- Only three Great Crested Grebes seen. One adult; one a juvenile; others too far away.

Birds noted flying over here:
- 1 Common Buzzard
- 4 Jackdaws

On /around the water:
- 35 Canada Geese
- 3 + 2 (1 brood) Mute Swan
- 36 (23♂) Mallard
- 1 (1♂) Teal
- 10 (3♂) Tufted Duck only
- 5 Moorhens only
- 21 Coots
- 3 Great Crested Grebes
- 46 Black-headed Gulls
- 2 Grey Herons

On a lamp pole:
- 1 Dicranopalpus ramosus-type harvestman

Noted elsewhere:
- *Red Admiral (Vanessa atalanta) briefly on the Ivy.
- rather fewer Common Wasps (Paravespula vulgaris) on the Ivy flowers despite the mild (but dull and breezy) conditions.
- 1 Grey Squirrel

A passable photo of an Ivy flower and a poor photo of a Red Admiral butterfly (Vanessa atalanta), all blowing about in the wind. When I next looked the butterfly had gone, I know not where. So long as the weather stays mild and the Ivy continue to flower it is possible that several species of butterfly will be visiting.

Priorslee Lake: 06:20 – 09:35

(241st visit of the year)

Another uncharacteristically quiet morning for the time of year. The only notable sighting was a Common Kestrel hovering over one of the remaining fields to the E at 07:55 and for a while thereafter.

Other bird notes:
- No Mute Swans! It does happen about this time most years when the adults take the cygnets away – somewhere safe? The adults usually come back within a week. Sometimes the cygnets also return until chased away in the Spring
- Very few early 'large gulls' with 16 Lesser Black-backed Gulls and two Herring Gulls stopping off and just seven unidentified gulls flying over.
- It was the Cetti's that was on 'warbler duty' today.
- Song Thrush singing again, briefly c.07:35.
- No birds seen leaving roosts around the water.

Overhead:
- 1 Canada Goose: inbound
- 76 Wood Pigeons: 32 of these in two migrant groups heading S
- 5 Black-headed Gulls flew high N together
- 39 Lesser Black-backed Gulls
- 7 unidentified large gulls only
- 202 Jackdaws
- no Rooks
- c.84 Starlings: group of four and one of c.80 birds
- 10? Redwings: five of these heard overhead pre-dawn
- 11 Pied Wagtails again
- 1 Chaffinch

Warblers noted:
- 1 Cetti's Warbler: no song but loud calls from the W end

Count from the lake area:
- no Mute Swans
- 2 (2♂) Mallard
- 3 (2♂) Gadwall again
- 38 (>16♂) Tufted Duck
- 7 Moorhens
- 57 Coots
- 1 Great Crested Grebe still
- c.100 Black-headed Gulls only
- 9 Herring Gulls
- 1 Yellow-legged Gull
- 43 Lesser Black-backed Gulls
- no Grey Heron

At / around the street lamps pre-dawn:
A surprising haul despite the slight rain.

Moths:
- 8 November Moth agg. (Epirrita sp.)
with:
- *1 ichneumon sp.
- *1 Harlequin Ladybird (Harmonia axyridis) var. succinea
- 2 Common European Earwig (Forficula dentata)
- 1 Pogonognathellus longicornis-type springtail
- *1 Larinioides cornutus Orb-web spider
- 1 Bridge Orb-web Spider (Larinioides sclopetarius)
- 1 Walnut Orb Weaver spider (Nuctenea umbratica)
- 1 Tetragnatha sp. Stretch spider
- 3 Paroligolophus agrestis harvestman
- 1 Leiobunum rotundum/blackwalli harvestman

In the sailing club shelter pre-dawn
- *1 Large House Spider-type: Eratigena sp.
- many Bridge Orb-web Spiders (Larinioides sclopetarius) as usual

Noted later:
- *1 November Moth agg. (Epirrita sp.) on the fence alongside Teece Drive.
- 1 clump of fungus sp.

A rather unusual day-time record of a November Moth agg. (Epirrita sp.). None of the eight I recorded on the lamp poles c.06:30 were there at 09:00, seeming not to like daylight (or rain?). This one was resting at waist-height on the fence between Teece Drive and the Wesley Brook at 09:15, providing a good photo opportunity.

Another record of an ichneumon sp. To my untutored eye recent sightings all the look to be of the same species. No idea what they might be though.

Covered in dew and / or raindrops this Harlequin Ladybird (Harmonia axyridis) of the form succinea (which usually has 17 spots). It was on one of the lamp poles pre-dawn. I have had many of this species trying to get in my house over the last few days.

Console yourself that this Large House Spider-type (Eratigena sp.) is not in your bath but minding its own business in the corner of the sailing club shelter. I wonder if shelter users during the day know what is lurking in the corners?

This has been confirmed as a Larinioides cornutus Orb-web spider. It is of the less frequent rust-toned form. Nigel has explained the difference between this species and the similar and frequently seen Bridge Orb-web Spider (L. sclopetarius) . On cornutus the leaf-like mark on the abdomen (called the folium) comprises islands of colour (or black) against the background. On sclopetarius the folium is more uniform with just the edges picked out in white or cream.

It is Autumn so there is always fungus popping up. Often, as here, in dark recesses of the wooded areas and requiring a flash photo. Flash, even with the compensation set, alters the colour balance somewhat. In real life this had a pale mauve rather then a brown centre to the cap. No idea as to species.

The Flash: 09:40 – 10:30

(218th visit of the year)

A large willow tree than was blown in to the lake some weeks ago was removed yesterday. Sadly they did not leave a 'wood pile' of the remains to attract wildlife. The base is still present so that, at least, will probably sprout next Spring.

Bird notes:
- The pair of Teal found again! Tucked up against the island where I see them most often.
- There seemed to be more Tufted Duck flying about as I arrived. Were some leaving? Rather few counted.
- Four Great Crested Grebes seen. Two were adults; one a juvenile; not sure about the fourth as it was too far away.

Birds noted flying over here:
- 16 Jackdaws
- 1 Siskin again

On /around the water:
- 23 Canada Geese
- 3 + 2 (1 brood) Mute Swan
- 31 (20♂) Mallard
- 2 (1♂) Teal
- 13 (5+♂) Tufted Duck only
- 10 Moorhens again
- 24 Coots
- 4 Great Crested Grebes
- 32 Black-headed Gulls
- 1 Lesser Black-backed Gull, briefly
- 1 Grey Heron

On various lamp pole:
- *2 November Moth agg. (Epirrita sp.).
- 1 Dicranopalpus ramosus-type harvestman

Noted elsewhere:
- many Common Wasps (Paravespula vulgaris) as always on the Ivy flowers.
- *three different species of fungus

Of all the November Moths I have seen this Autumn this is by far the most heavily-marked. Even so it is not possible to ascribe to a particular species within the Epirrita group.

I found three different species of fungus, all in the small wooded area in the top NW corner. Here is species #1.

Species #2. This specimen seems to have had a larger part break off. Or is it just sprouting sideways at the base?

A plan view of species #3.

And a side-elevation of the same specimen showing the gill structure.

Priorslee Lake and The Flash

8.0°C > 12.0°C: Areas of cloud associated with showers. Some sunny spells. Light / moderate S wind. Mostly very good visibility.

Sunrise: 07:53 BST

Priorslee Lake: 06:20 – 09:25

(240th visit of the year)

A generally quiet morning for visual migration. However the highlight was a lone Brambling that flew W at 08:10. My 111th bird species here this year.

Numbers perhaps slightly affected by a discharge from somewhere in Stafford Park that was lingering in early light winds. As a result the W end very misty. Exactly what this discharge is - it happens most days c.06:30 - is unclear and might only be water vapour from industrial units being started. Only when the wind is in the S does it affect the lake (and the M54). This morning it seemed to be catching in my throat. As a result I was positioned non-optimally for watching roost departures.

Other bird notes:
- Only the pen Mute Swan was present early and she flew off NE at 08:25 (I am assuming its identity – I did not read any ring).
- All the early large gulls that stopped off were positively identified as Lesser Black-backed Gulls and are logged as such. The overflights were not specifically identified.
- A Chiffchaff was calling along the N side today.
- The only bird seen leaving a roost around the water was a lone Starling.

Overhead:
- 3 Canada Geese: inbound together
- 1 Stock Dove
- 27 Wood Pigeons only: nine of these in a single migrant group heading SSW
- 25 Lesser Black-backed Gulls
- 33 unidentified large gulls
- 1 Grey Heron
- 1 Common Buzzard
- 237 Jackdaws
- 2 Rooks only
- 10 Skylark
- c.100 Starlings: three groups one of c.80 birds
- 1 Fieldfare
- 12? Redwings: all these heard overhead pre-dawn
- 11 Pied Wagtails
- 1 Meadow Pipit
- 5 Chaffinches
- 1 Brambling
- 1 Siskin again

Warblers noted:
- 1 Chiffchaff: no song
For anyone interested in Cetti's Warbler song then BBC Radio 4's 'Tweet of the Day' at 05:58 tomorrow (26th) will be featuring it.

Count from the lake area:
- 1 Greylag Goose: departed
- 1 Mute Swan: departed
- 9 (>3♂) Mallard: all departed together
- 3 (2♂) Gadwall
- 32 (>12♂) Tufted Duck
- 6 Moorhens again
- 60 Coots
- no Little Grebes
- 1 Great Crested Grebe again
- >175 Black-headed Gulls again
- 4 Herring Gulls
- 26 Lesser Black-backed Gulls
- no large gulls: see notes
- 1 Grey Heron: departed

At / around the street lamps pre-dawn:
Probably too much dew on the lamps for many insects to settle.

Moths:
- 1 November Moth agg. (Epirrita sp.) again
with:
- *1 springtail sp.
- 1 Clubiona sp. spider
- *1 Walnut Orb Weaver spider (Nuctenea umbratica)
- 1 Paroligolophus agrestis harvestman

In the sailing club shelter predawn:
- *2 White-legged Snake Millipedes (Tachypodoiulus niger)
plus the usual array of mainly Bridge Orb-web Spiders (Larinioides sclopetarius)

Noted later:
- 1 Grey Squirrel

A near-by shower. Luckily it passed to the N and I stayed dry – this time.

A Great Spotted Woodpecker trying to hide from me. It has successfully hidden its nape so I can't tell whether it has the red patch of a male or whether this is a female.

Today's springtail sp. ploughing through the dew spots. I would judge a different species as the antennae look significantly shorter than those I have provisionally logged as Pogonognathellus longicornis-type.

A White-legged Snake Millipede (Tachypodoiulus niger) making its way underneath a dew-spattered spider's web. It is on the corrugated inside wall of the sailing club shelter.

You WILL all enjoy looking at spiders. A six-legged(?) male Walnut Orb Weaver (Nuctenea umbratica). His left-side third leg may be tucked up: the left front legs looks to be missing.

The Flash: 09:35 – 10:35

(217th visit of the year)

Bird notes:
- The pair of Teal not located.
- No Goosanders again.
- At least one Skylark over – from calls only: too high for me to see.
- A Redwing flew out of trees on the island.

Birds noted flying over here:
- 1 Feral Pigeons
- 3 Wood Pigeons
- 10 Jackdaws
- 1+ Skylark
- 1 Siskin

On /around the water:
- 27 Canada Geese
- *3 + 2 (1 brood) Mute Swan
- 30 (20♂) Mallard
- no Teal
- 40 (1+♂) Tufted Duck
- 10 Moorhens
- 24 Coots still
- 2 + 3 (1 brood) Great Crested Grebes
- 41 Black-headed Gulls
- 1 Herring Gull
- 1 Grey Herons

On various lamp pole:
- 1 November Moth agg. (Epirrita sp.).
- *1 Hawthorn Shieldbug (Acanthosoma haemorrhoidale)
- 1 Birch Shieldbug (Elasmostethus interstinctus)
- *2 Tetragnatha sp. Stretch spiders

Noted elsewhere:
- many Common Wasps (Paravespula vulgaris) on the Ivy flowers.
- *several Common Droneflies (Eristalis tenax) also on the Ivy flowers.
- 1 Grey Squirrel

The Mute Swan cygnet seemed to be making overtures to the 'spare' adult female – or vice versa. As soon as the parents noticed they separated them.

I am now confused (not an uncommon experience). When I saw this hoverfly I assumed it would be a Stripe-faced Dronefly (Eristalis nemorum). But no! The brown cloud and stigma in the wing rules out that species. Seems from photos on Steven Falk's web site that Common Dronefly (Eristalis tenax) also has a stripe down its face. Ho hum. This is a male with its eyes meeting.

Yesterday's Birch Shieldbug (Elasmostethus interstinctus) was still at the very top of its lamp pole. This Hawthorn Shieldbug (Acanthosoma haemorrhoidale) was at eye-level on a different lamp pole in squirrel alley giving much better views.

Right on the sun / shade divide on a lamp pole was what turned out to be one of the two Tetragnatha sp. of Stretch spiders. Not easy without the magic camera.
