Priorslee Balancing Lake and The Flash

4.0°C > 6.0°C: Scattered below a medium-high overcast at dawn, the low cloud increasing later. Rain after 09:15. Moderate southerly wind. Very good visibility, less good after rain commenced.

Sunrise: 07:16 GMT

Priorslee Balancing Lake: 06:20 – 09:10

(39th visit of the year)

An addition to my 2026 bird species list for here. A Reed Bunting was making an effort to sing a few undistinguished notes along the South side at c.06:50 [I recorded the first song on 27 February last year]. This species has traditionally formed small winter roosts at the West end. Not this Winter. There are normally three breeding territories. These have been occupied by singing males for the last two years without any sign of successful breeding. Species #60 here this year for me.

Bird notes:
- six Goosanders today: certainly two full adults. Apparently four brownheads/ducks with none of these seeming to be the recently seen immature drake.
- back to just two pairs of Great Crested Grebe.
- the grass behind the dam is in much demand: at 06:50 there were two Canada Geese, a pair of Mallard, a Moorhen and 18 Coots feeding there.
- the first gull, a Lesser Black-back, flew straight in at 06:56. Over 20 more passed over before the main arrival of large gulls. This contained almost as many Herring Gulls as Lesser Black-backs. The first of just 17 Black-headed Gulls was not noted until 07:25.
- the Great (White) Egret arrived from the North at 06:47.
- most of the Jackdaws seen were passing very low and far to the East. Probably many overlooked / unseen. The Rooks were all flying much higher as well as closer.
- three Mistle Thrushes flew East loosely together: two carried on, across Castle Farm Way; the other stopped in trees on the lake side of Castle Farm Way.
- a Chaffinch was heard in song: my first this year [31 January was my first last year].
- also two Greenfinches were giving their nasal territorial call: I heard one on 20 January at The Flash. [I don't have a record of the first date for here in 2025].
- mobile group(s) of up to 30 Siskins were noted.

Bird(s) noted flying over here:
- 4 Canada Geese: a pair flew South and a pair flew West.
- 20 Wood Pigeons
- 1 Black-headed Gull
- 8 Herring Gulls
- 81 Lesser Black-backed Gulls
>150 Jackdaws
- 173 Rooks
- 2 Mistle Thrushes
- 1 Pied Wagtail

Counts from the lake area:
- 9 Canada Geese: the resident pair upset at three other pairs and a single arriving separately
- 12 (8♂) Mallard
- 18 (13♂) Tufted Duck
- 6 (2♂) Goosander
- 6 Moorhens
- 28 Coots
- 5 Great Crested Grebes
- 17 Black-headed Gulls
- 40 Herring Gulls
- 44 Lesser Black-backed Gulls
- *4 Cormorants
- *2 Grey Herons: when the second arrived it was soon chased away
- 1 Great (White) Egret

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

Flies:
- *3 small plumed midges: 2 males and 1 female

Springtails:
- *4 globular springtails, some perhaps Dicyrtomina saundersi-type

Spiders, harvestmen etc.:
- *1 Bridge Orb-web Spider Larinioides sclopetarius [Bridge Orbweaver]
- *2 Long-jawed Orb-web Spiders Tetragnatha sp.

An attempt at hand-holding a pre-dawn time exposure to show that the early cloud was at medium-high level. Must take more water with it (or perhaps I just needed coffee).

Looking West after (nominal) sunrise it looked promising. It did not stay like this.

Three of the four Cormorants present. The left-hand bird is the most-advanced in to breeding plumage I have seen here this year. In addition to the white thigh-patch there are white plumes around the throat and a small spiky crest.

One of the Grey Herons being chased away. The bill colour indicates this is a breeding condition adult. For reasons I cannot explain my erstwhile defunct Sony RX10 camera started working again when I checked it last evening. Fingers crossed.

As usual the Siskins were high up in the trees against what was by now a lowering sky with spits of rain. A male here.

One of four small plumed midges on the street lamp poles: this, with feathered antennae, is a male.

A Bridge Orb-web Spider Larinioides sclopetarius closing in on a globular springtail. The spider looks smaller than usual but I guess all spider have to start as spiderlings from an egg and gradually grow (by eating springtails?).

And a Long-jawed Orb-web Spider Tetragnatha sp. also closing in on a springtail. A larger springtail to its right.

A few seconds later and the first springtail seems to have gone!

The Flash: 09:15 – 10:20

(36th visit of the year)

Bird notes:
- the single Mute Swan still present: again it did not come close-enough for me to check its sex / any ring.
- did I overlook the drake Pochard yesterday? a drake was present today.
- two Great Crested Grebes again: both of them had head plumes.
- *just a male Blackcap with other species at the feeding station. The arrival of the refuse cart saw the birds disperse (the rain did not help!)
- *>30 Siskins again seen both on the feeders and in the trees.

Bird(s) noted flying over here:
- 1 Herring Gull
- 3 Jackdaws

Noted on / around the water:
- 22 Canada Geese
- no Greylag Geese
- 1 Mute Swan
- *33 (23♂) Mallard
- 1 (1♂) Pochard
- 20 (11♂) Tufted Duck
- 10 Moorhens
- 37 Coots
- 2 Great Crested Grebes
- *21 Black-headed Gulls
- 2 Herring Gulls: both (near?) adults
- no Cormorants
- no Grey Heron

Of note around the area:
Nothing else

Food!! Five Black-headed Gulls try to steal the bread from a trio of Mallard (two drakes).

"You'll choke!"

I am not sure how the first-winter Black-headed Gull is going to cope with its prize. Another first-winter is anxious to help.

Another first-winter Black-headed Gull giving a good view of the feather tracts in the wing. This bird seems to have replaced two of its black-tipped tail feathers. I suspect the original feathers were damaged and regrown as adult feathers. The moult would not normally happen until June time.

A Great Spotted Woodpecker. With red on the nape this is a male. Nice red trousers.

Just a male Blackcap...

....visited the feeders while I was there. As noted the arrival of a refuse lorry and the operatives saw the birds go in to cover.

A female Blackbird. Some individuals, as here, show rufous tones. This bird may be a first year bird: the bill is not all-yellow (never as bright as the male); and her pale yellow eye-ring is barely visible.

A Song Thrush started by looking for food dropped off the feeders but...

...then decided to visit the feeders. I cannot recall this shy species visiting feeders too often in the past.

Do I need to say – a Robin.

A male Siskin on one of the feeders.

A messy eater.

And a female.

Another female shares the feeder with a Blue Tit.

Yet another rain delayed start.

Priorslee Balancing Lake: 11:15 – 11:45

(38th visit of the year)

Again viewing from the dam-top area only.

Very quiet. While I was present I noted no birds flying in or out and none flying over.

Bird notes:
- a decrease in the Tufted Duck numbers today. Still a surfeit of drakes.
- seven Goosanders today: two full adult and one immature drake with four brownheads/ducks
- an additional Great Crested Grebe.

Bird(s) noted flying over here:
None

Counts from the lake area:
- 2 Canada Geese
- 2 (1♂) Mallard
- 21 (15♂) Tufted Duck
- *7 (3♂) Goosander
- 5 Moorhens
- 34 Coots
- 5 Great Crested Grebes
- 9 Black-headed Gulls
- 5 Herring Gulls: all immatures
- no Lesser Black-backed Gulls
- 6 Cormorants
- 2 Grey Herons
- 1 Great (White) Egret

 Something amusing the duck Goosander perhaps?

Time for a stretch. Apologies for the standard of today's photos. My back-up camera does not have the same capability. I was also struggling to remember the best settings to (partially) compensate for the poor light. These are my best attempts at learning what is possible.

The Flash: 09:55 – 11:05

(35th visit of the year)

Bird notes:
- a single Mute Swan still present: it did not come close-enough for me to check its sex / any ring.
- many Mallard apparently hiding this morning.
- no sign of yesterday's drake Pochard or Goosanders.
- after a dearth of Moorhens yesterday there were birds on the wet grass all around the lake today.
- two Great Crested Grebes again. However only one of them had head plumes.
- a female Blackcap flew off from the feeding station as I arrived there. No further sightings of birds of either sex during the next 15 or so minutes.
- *Siskins again seen both on the feeders and in the trees.
- a Lesser Redpoll flew North and I assume the same flew South a minute or so later.

Bird(s) noted flying over here:
- 1 Herring Gull
- 1 Lesser Redpoll

Noted on / around the water:
- 21 Canada Geese; the goose recently seen dead in the water is now buried in the reeds at the top end.
- no Greylag Geese
- 1 Mute Swan
- 19 (15♂) Mallard
- no Pochard
- *33 (22♂) Tufted Duck
- no Goosander
- 16 Moorhens
- 36 Coots
- 2 Great Crested Grebes
- *12 Black-headed Gulls
- 4 Herring Gulls: two (near?) adults; one third- and one first-winter
- no Cormorants
- no Grey Heron

Noted around the area:

Fungus:
- *a crust-type fungus, perhaps Hen of the Woods Grifola frondosa.

A drake Tufted Duck.

 ...and a duck.

A Moorhen on the lookout for spilt food.

The nest-building Coot seems to be going for the height-record.

More in the open with better light so a more acceptable photo of a Black-headed Gull.

More light would have helped here. I am puzzling as to whether it is the inner or outer webs of the Wood Pigeon's primary feathers that are pale-edged. Not something you can notice with the naked eye.

This looks to be a first year male Blackbird with retained juvenile brown feathers in its wings.

Another not very good photo: a Coal Tit showing the usually hard-to-see peachy flanks.

A trio of tit species happily(?) sharing a feeder. A Great Tit on the left and a Long-tailed Tit above a Blue Tit on the opposite side.

A poor photo of a female (thin "zip") Great Tit.

A Long-tailed Tit with a feeder to itself and so...

...tucks in.

A male Chaffinch. An unusually sombre-toned individual.

Chomp, chomp. A female Siskin munches away.

A crust-type fungus. Obsidentify had no meaningful suggestion. Google Lens was perhaps better suggesting either Sliver-leaf Fungus Chondrostereum purpureum or Corticium roseum. But as their scientific names imply the first should look purple-tinged and the other rosy-hued. Consulting NatureSpot the best match seems to suggest Hen of the Woods Grifola frondosa. But...

Another day when a late start seemed the best option.

Priorslee Balancing Lake: 09:05 – 10:25

(37th visit of the year)

Viewing from the dam-top area only.

Bird notes:
- a significant increase in the Tufted Duck numbers. The model boat club using the West end of the water may have moved them all closer to the dam. Nevertheless an increase and a surfeit of drakes.
- four Goosanders today: both a full adult and an immature drake, each accompanied by a duck.
- back to two pairs of Great Crested Grebes.
- three local Common Buzzards were see circling: one over the West end; and two over Castle Farm Way.

Bird(s) noted flying over here:
- 1 Feral Pigeon
- 7 Wood Pigeons
- 1 Herring Gull

The Flash: 10:35 – 11:15

(34th visit of the year)

Bird notes:
- the unringed cob (?) Mute Swan was patrolling the entire water.
- yesterday's drake Pochard still present.
- a (small) increase in Tufted Duck numbers here – as well as at the Balancing Lake.
- a pair of Goosander today.
- *at least two different male Blackcaps were at the feeding station.
- *Siskins seen both on the feeders and in the trees.

Bird(s) noted flying over here:
- 3 Herring Gulls
- 3 Lesser Black-backed Gulls
- 5 Jackdaws

Noted on / around the water:
- 23 Canada Geese; the goose seen dead in the water for the last two days not noted.
- no Greylag Geese
- 1 Mute Swan
- 29 (21♂) Mallard
- 1 (1♂) Pochard
- 31 (16♂) Tufted Duck

- 6 Moorhens only
- 35 Coots
- *2 Great Crested Grebes
- 47 Black-headed Gulls
- *3 Herring Gulls: two (near?) adults; one first-winter
- no Cormorants
- no Grey Heron

Around the area:
Nothing of note

This was about as friendly as the two Great Crested Grebes got.

Proving it is not quite a full adult Herring Gull: the dark feathering at the bend of the wings is the give-away.

Three Herring Gulls here. The bird on the left looks to be an adult with no obvious black on the bill. Not sure about the middle bird: does it have some brown in the folded wings or is that shadow? The bird on the right is a first year with a full tail band.

A Blue Tit awaiting its turn at the feeders. Strangely Great Tits seem to be infrequent visitors.

The Long-tailed Tit party did not visit the feeders.

They were unusually low down in vegetation along the side of the water.

Giving acceptable views.

This may well be the last photo I take with my usually trusty Sony RX10 Mk.4. A sometime intermittent fault now seems to be fatal. Hence there will be a few more photos than usual today: last of the Mohicans! I do have a back-up camera, but not with the same capability.

I'll try to get a better photograph of this male Blackcap...

...this other male chased it away.

This one visited later. Which one was it? Or, indeed, was it a third? Sharing with a Siskin.

A "tufted?" female Blackbird. No idea why she looks tufted.

A Robin questioning when it gets its turn?

A Mrs. Chaffinch on the dish feeder. This species finds hanging feeders a challenge, though females seem to manage better than males.

Another female feeding where most often seen – on the ground. Note this one has "scale leg". This is caused by a virus with an unpronounceable name. The virus seems to have little impact on the birds.

A male on the ground. Just visible here is the greenish tone on the rump – usually covered except in flight when it is hard to see.

Another male Chaffinch.

Looking brutish is a male Greenfinch.

A male Siskin.

A male and female have a discussion over elevenses.

These two prefer eating to talking.

A female Siskin.

A female Siskin shares the feeder with a Goldfinch. I have assumed that gravity means the feeder is vertical and it is the pole that leans!
