* = a species photographed today

Priorslee Balancing Lake: 06:25 – 09:25

(276th visit of the year)

Highlight was seeing a Water Rail wandering and poking about in one drainage channels that only contains water after significant rainfall.

Bird notes:
- the Canada Goose with the injured leg was sleeping on one of fishing platforms. Later it was hobbling on the south-west grass again.
- some movement among the Mute Swans. At first light there were 20 (near) adults, four more than on most recent days. Later there were only 11 (I did not notice any leave). As I was walking up Teece Drive to depart to The Flash there were three adults flying around the over the lake: coming? going? flying around? The two cygnets/first winters were present throughout.
- the trio of Gadwall seen again. I suspect they are just hiding on visits where I fail to see them.
- probably more Black-headed Gulls that I have tabulated. Something spooked them before it was light-enough to get an accurate count and many did not settle back.

Later:
Nothing noted

Slightly fuzzy as the waning Cold Moon was shining through a thin layer of high cloud.

The early sky did not show much promise.

It soon got better.

Even better.

Much better

A group of the Mute Swans decided to crash the photos so...

 ...I decided to make a feature of them.

Record shots only. The Water Rail was deep in cover and there were very many twigs and leaves in the way. The long red bill and the two shades of brown on the back can be seen.

The best of a not very inspiring bunch. As far as I can recall this is the first time I have managed to photograph this species here.

The only Winter Moth, a male, Operophtera brumata today.

This fly is possibly Scoliocentra villosa. The red eyes, grey thorax and orange abdomen point to this species.

One of two barkflies of the Ectopsocus briggsi aggregate.

I wonder what this is? It felt almost rubbery. I tried to move it from the street lamp pole in to my palm but it fell to the ground and I could not relocate it. I am sure it is not the Serotine (bat) that Obsidentify is confident it is. All the (many) suggestions from Google Lens show a segmented body. So I suspect it is not "animal" but quite what I have no idea.

The Flash: 09:30 – 10:35

(278th visit of the year)

Bird notes:
- when I arrived there were at least 48 Greylag Geese inside and around the island with the two white feral geese. Later 43 more arrived in three groups.
- numbers of Tufted Duck and Pochard again "best effort" with many birds continually diving and moving around.
- no Great Crested Grebe (or Little Grebe) noted.

Bird(s) noted flying over here:
- 1 Lesser Black-backed Gull

Noted on / around the water:
- 7 Canada Geese
- *91 Greylag Geese: see notes
- 2 mainly white feral geese
- *6 + 2 (1 brood) Mute Swans
- 33 (22♂) Mallard
- 13 (>6♂) Pochard
- 86 (>56♂) Tufted Duck
- 15 Moorhens
- 86 Coots
- 11 Black-headed Gulls
- 6 Herring Gulls: two adults; four second winters
- 1 Lesser Black-backed Gull: adult briefly

Elsewhere:
Nothing noted

Once again the four non-resident adult Mute Swans went for a fly around together. Later they were as two well-separated pairs as usual.

 24 – count them – Greylag Geese arrive with some of the lowering their undercarriage.

Splash down.

Zoomed in on part of the group. Worryingly the bird top dead-centre seems to be slightly smaller and to have a small and partly dark bill. These features might indicate it to be a Pink-footed Goose. I think not: there is too much pale showing in the wing. I cannot pick this bird out in any of the other photos I took of this group.

I know we are not supposed to anthropomorphise but this Song Thrush look glum.
