Priorslee Balancing Lake: 06:20 – 09:30

(294th visit of the year)

Bird notes:
Nothing very exciting this morning.
- the Tufted Duck count may be incomplete. Something spooked some of them while I was in mid-count.
- Black-headed Gulls were again later arriving, all after 07:25. I thought c.125 though as they streamed away (and I was not counting) there seemed to be more.
- c.250 Lesser Black-backed Gulls were on the water by 07:05 and another large arrival took the total to at least 500 by 07:20. Among these were at least 23 Herring Gulls.
- a later arrival produced 27 Herring Gulls, on Yellow-legged Gull and at least 107 Lesser Black-backed Gulls.
- the Great (White) Egret present again. I did not see it arrive.
- some Jackdaws and Rooks lost in both low cloud and poor visibility.

- 16 Wood Pigeons only

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

Moths:
- 1 male Winter Moths Operophtera brumata: flushed from vegetation under a lamp

Slugs, snails etc.:
- *1 Girdled Snail Hygromia cinctella

Nothing else at all

Later on the Teece Drive fence or elsewhere:
Nothing noted

A gull that still puzzles me. It seemed dark for an adult-winter Lesser Black-backed Gull albeit there is a contrast between the folded wings and the black wing-tips. It has some head-streaking that a Great Black-backed Gull would not show: yet the legs look pink rather than yellow as they should if it is a Lesser.

Definitely pink legs. Most odd. While the yellow of the legs is brightest when this species is in breeding condition I think as an adult this bird's legs should appear yellow at this date.

A duck (female) Pochard in flight. This species does have a pale wing-bar but because the wings are essentially pale it is not obvious.

Apart from one Winter Moth Operophtera brumata flushed from underneath a street light the only creature I noted here pre-dawn was this Girdled Snail Hygromia cinctella. One of the easier snails to identify with the pale line around the apex of the shell.

A duck (female) Tufted Duck looking for somewhere to splash down. You can almost count its retrices (tail-feathers). Most species of bird have 12 retrices (Feral Pigeons often don't due to selective breeding).

A duck (left) and drake (right) Tufted Duck.

A quartet. A duck leads three drakes. On the central two birds the "tuft" can be seen blowing in the wind.

And here are seven. None of these is a sharp as I would have liked: the light-level was poor.

In the Priorslee Avenue tunnel pre-dawn:

Moths:
- 1 male Winter Moth Operophtera brumata: presumed same as yesterday

Flies:
- 4 midges

Spiders, harvestmen etc.:
- none!

The Flash: 09:35 – 10:40

(287th visit of the year)

Bird notes:
- no Shoveler noted.
- *two pairs of (Common) Teal
- a single brownhead Goosander flew off leaving two drakes and four other brownheads on the water.
- I could only find two Great Crested Grebes.
- three Cormorants: one was the bird seen yesterday tied-up in fishing lines and still like it.
- no Grey Herons yesterday: three today!

Bird(s) noted flying over here:
None

Noted on / around the water:
- 7 Canada Geese
- 35 (22♂) Mallard
- *4 (2♂) (Common) Teal
- *6 (3♂) Pochard
- 15 (6♂) Tufted Duck
- 7 (2♂) Goosander: departed
- 9 Moorhens
- 52 Coots
- 2 Great Crested Grebes
- 26 Black-headed Gulls
- 2 Herring Gulls only
- 3 Cormorants
- *3 Grey Herons

Noted around the area:

Moths:
- 3 male Winter Moths Operophtera brumata: two of these where they were yesterday
The bank of Ivy was devoid of insects.

*Fungus:
- possible Crystal Brain Fungus Exidia nucleata
- unidentified bracket fungus.

Two pairs of (Common) Teal with the drakes in the centre.

Now the two ducks are central. On the left-hand duck the white flash on the side of the tail is well-seen.

A selection of Pochard photos. A drake.

Another drake. In dull conditions the fine vermiculations show. Sadly the colours don't!

Here a duck.

One I am puzzling over. The head pattern looks like a duck yet the flanks show some vermiculations and the stern is dark, both features shown by drakes. Perhaps a first-winter drake late to acquire adult plumage?

Pity about the twig across the head of this Grey Heron. I could not reposition without even more twigs getting in the way.

Very small fungi growing on the end of broken branch. Small bracket fungus apparently. No idea of the species. I also note bottom left a jelly fungus. That could be Crystal Brain Fungus Exidia nucleata. There are of course many similar species. This species is common and widespread on rotting wood.
