Priorslee Balancing Lake and The Flash

5.0°C > 7.0°C > 6.0°C: Some breaks developing after overnight rain. Later these filled in with cloud lowering and light drizzle. Light westerly wind. Good visibility, poor in drizzle.

Sunrise: 07:54 GMT

* = a species photographed today

Priorslee Balancing Lake: 06:30 – 09:35

(24th visit of the year)

Bird notes:
- a drake Goosander flew through West at 07:40.
- a Water Rail was in a water-filled ditch along the North side. The recent storms have deposited even more twigs in the way of any chance of a photo.
- *four Great Crested Grebes present. A pair displaying. Another with head plumes and a fourth yet to grow the plumes and likely a first year bird.
- after yesterday's plethora of gulls present from before 07:10 there was no action before 07:28 when 12 Lesser Black-backed Gulls looked at the empty lake and moved on. It was 07:35 before the first of 55 started to arrive with 11 Herring Gulls. It was 07:40 before the first four Black-headed Gulls arrived with numbers peaking at a paltry 28. Later an adult Yellow-legged Gull dropped in
- two egrets were seen flying south-east to the East at 07:50. Another flew West to the North at 08:25. I was unable to get a positive identity on any of these though I suspect they were all Great (White) Egrets. *'Our' bird was present throughout.
- a Chaffinch gave a brief burst of song. It is not every year that I record song in January [16 February 2024 and 19 February 2023 were the first dates in those years].

The cloud from the overnight rain beginning to break.

Just a touch of colour.

Mrs. Pochard grinning at me. Count those tail feathers (properly called retrices).

What I believe to be a first year Great Crested Grebe still to develop its head plumes.

A distant pair, with plumes, displaying.

This can be confirmed as an adult Yellow-legged Gull by the extensive white end to the outer primary. Herring Gulls show a white "mirror", the tip being black, much like the adjacent feather.

Another view. It definitely needs a camera to see this feature. Otherwise it is the tone of the back that is the clue – the legs are usually in the water and the feet are pink which are the easiest part to see in flight.

A bit of a puzzle with this Cormorant. It lacks any pale on the belly suggesting it is an adult but it has no white thigh-patch or head-plumes suggesting it is coming in to breeding plumage.

A Grey Heron was fishing in the Wesley Brook.

"Splosh". Seems the target was deep in the brook!

Missed!

"What's that over there?"

Try again.

Success!

The Great (White) Egret flies off complaining about my presence. The call is nowhere near as hash and far-carrying as that of a Grey Heron.

Still complaining!

 Two winter craneflies Trichocera sp. posing neatly.

This fly is possibly Scoliocentra villosa, a species with red eyes, a grey thorax and an orange abdomen.

One of several springtails of the Tomocerus sp. type, all perhaps different species. This one may be Tomocerus vulgaris.

This looks a good candidate for Pogonognathellus longicornis.

Perhaps another P. longicornis. with one of the much smaller globular springtails of the Dicyrtomina type.

A spider I found on a street lamp pole pre-dawn. Looks easy to ID. Neither Obsidentify nor Google Lens gave me an ID that was in the size range of this species so it stays unidentified.

Perhaps easier to ID is this spider on the wall of the Telford Sailing Club HQ. I think a Missing Sector Orb-web Spider Zygiella x-notata.

Priorslee Balancing Lake: 06:25 – 09:30

(23rd visit of the year)

Bird notes:
- *two Mute Swans flew in together - a sub-adult and a first year bird. The first year soon departed. The residents had more trouble persuading the sub-adult to leave.
- there seems to be a gradual departure of some Coots heading off to breeding sites elsewhere.
- at least two more Great Crested Grebes present. As usual they were difficult to keep track of: there may well have also been a fourth.
- the gulls were very 'jumpy' this morning and would not settle. I thought initially this might be due to a Cormorant that was fishing in the area by 07:10. However the Cormorant left shortly afterwards and the gulls still would not settle. Numbers are therefore approximate.

It did not look as if the sunrise would amount to much.

A few clouds provided some colour later.

The sub-adult Mute Swan arriving.

With the first year bird right behind.

One of two pairs of Gadwall present. The drake at the front.

The angle on this arriving Cormorant makes it look as if the white thigh patch is in the middle of the belly. Also the early morning sun makes that white patch look pale yellow.

The Great White Egret attempting to hide in the reeds. Once settled it was indeed very hard to see.

A Wood Pigeon basks in the warmth(?) of the early sun while keeping an eye on me.

This Early Moth Theria primaria was the only insect on the frost-covered street lamp poles this morning. It was too high up the pole for good photo.

A drake Pochard with the sun catching the red eye. The harsh light prevented the details of the back plumage from showing.

And a duck Pochard. Again perhaps the harsh light but she does look rather "washed-out".

I heard this pigeon calling quietly and thought it a Stock Dove. Walking to get a better angle shows that it is a Feral Pigeon. These come in all manner of plumages. This is basically a "blue morph", closest to their Rock Pigeon wild ancestors. It sports a few white feathers on the head and a chequered pattern on its wings. Note the orange eye. Whatever colour variant an individual is it will always have a clean white rump, not shown by Wood Pigeons or Stock Doves.

A Black-headed Gull shows that if you have wings you can walk on water.

I am still not 100% sure that this is a first year Herring Gull. The tail band is more extensive and solid than I would expect, more like a Lesser Black-backed Gull which both the back tone and the markings on the upper tail show it isn't. That points to a Yellow-legged Gull but I think the pale inner primaries are too extensive and contrasting for that species. So Herring Gull it stays.

Grey Herons have not been here for several weeks. One was back lurking alongside one of the bridges.

My first hoverfly of the year. The pale front and mid legs are pale indicating this is a Tapered Dronefly Eristalis pertinax. As it is a female (the eyes do not meet) is does not have a noticeably 'tapered' abdomen.

Priorslee Balancing Lake and The Flash

3.0°C > 5.0°C: The overnight white frost covering the pavement was beginning to fade as the low-medium cloud rolled in ahead of the next storm. The light south-easterly wind was freshening all the while. Good visibility.

Sunrise: 08:01 GMT

* = a species photographed today

Priorslee Balancing Lake: 06:30 – 09:20

(22nd visit of the year)

Bird notes:
- it was most certainly a different Great (White) Egret that flew South at 08:10: I was looking at "ours" at the time.
- all change again with the gulls. After the paucity of Black-headed Gulls yesterday there were at least 350 (with c.50 Lesser Black-backed Gulls) settled on the water at 07:15. The lack of noise suggested that these had probably roosted here. A large group of at least 85 more Lesser Black-backs arrived from the South at 07:35. At least 15 Herring Gulls were with them. Just a scatter of additional birds made it in.
- a decent count of Rooks passing. Once again fewer Jackdaws. In years gone by there were usually at least twice the number of Jackdaws (and more of both species).

Bird(s) noted flying over here:
- 7 Wood Pigeon
- 1 Collared Dove

The Flash: 09:25 – 10:30

(20th visit of the year)

Bird notes:
- a drake Pochard had joined yesterday's duck.
- I have logged the drake Goosander as a fly-over. It is just possible that it was leaving from hiding away at the top and not, as I thought at the time, having a quick look before flying on. My first in Shropshire this year where it has been much scarcer than recently all Winter.
- the Little Grebe moulting in to breeding plumage was swimming toward the island as I arrived. I did not see it again.

Bird(s) noted flying over here:
- *1 (1♂) Goosander
- 2 Stock Doves
- 5 Lesser Black-backed Gulls

New Bird Species
Another addition to the bird species on my site for here in 2025:
47 Goosander

My what big feet you have. Canada Geese show off their size 12s.

A duck Mallard coming for splash-down. I am not sure I realised the tail feathers would be the first to touch.

A duck Pochard.

A quartet of drake Tufted Ducks with a drake and a duck Pochard. The Tufties have full crests by now.

A bit "noisy" with little light for the camera to play with. A passing drake Tufted Duck.

Perhaps a better shot of a different bird.

The drake Goosander flying around, The pink flush shows it is coming in to breeding condition.

Here showing the upper wing pattern. The duck is mainly brown apart from a pale neck. Her wing has the white wing panel on the rear half of the wing only.

I did a double-take with this first winter Black-headed Gull. The dark along the flanks (actually the lesser coverts of the folded wing) seemed unusually dark suggesting first winter Little Gull. That species has a small all-dark bill as well as being smaller. These feathers on most first winter Black-headed Gulls are now faded and being replaced by pale adult feathers so this is an anomalous bird.

An adult winter Black-headed Gull. Note the alula feather extended at the bend of the wing. This helps the bird in low speed manoeuvrability. Aircraft manufacturers copied this idea as leading-edge slats which are extended for landing and take-off.

Gull identification is often a challenge. These are both first winter Herring Gulls.

This is a first winter Lesser Black-backed Gull. The feather shafts are visible on the gull's right wing.

The same bird from above. Note the dark primaries and secondaries and that the coverts of these feathers are also dark. The inner primaries barely contrast with the other feathers. The tail is solidly dark with the upper tail clean white.

And again. Here the left wing is fully spread and with the inner primaries fully spread it can be seen that the inner webs of these feathers are pale. Not many bird books show this.

This adult Lesser Black-backed Gull is easy to ID. The winter head-streaking is now being lost.

The two Cormorants that dropped in. They then dived and resurfaced by the island.

A Blue Tit of course. The blue is almost glowing here. "They" have discovered that, like many birds, the eyes of Blue Tits are sensitive to light in the ultra-violet part of the spectrum and to them the blue tones do indeed 'glow' [how do "they" know?].
