The Flash and Priorslee Balancing Lake

11.0°C: Mostly overcast with a few brighter moments. Strong south-westerly wind. Very good visibility.

[Sunrise: 08:18 GMT]

* = a species photographed today

Another delayed start. The forecast was rain: it didn't. It also said the strong wind would ease after 08:00. It didn't: well not much until after 12:00. Pah!

So as usual with late starts it was The Flash first.

Priorslee Balancing Lake: 11:40 – 12:20

(275th visit of the year)

Just from the dam-top. The model boat club were using the West end of the water.

Bird notes:
- the Canada Goose with the injured leg was trying to get sympathy from the model boat club members who were using the West end of the water. The goose was hobbling between the cars parked on the south-west grass.

Bird(s) noted flying over here:
- 1 Jackdaw

Counts from the lake area:
- 1 Canada Goose
- 16 + 2 Mute Swans
- 2 (1♂) Mallard
- 1 (0♂) Tufted Duck
- no Moorhens
- 242 Coots
- 4 Great Crested Grebes
- 36 Black-headed Gulls
- *24 Herring Gulls
- 35 Lesser Black-backed Gulls

Not much of note here this morning. This first winter gull caught my eye. The wing pattern with paler inner primaries point to it being a Herring Gull as does the mottling on the upper tail. The tail band itself looks unusually wide and neat for this species. This combination would point to a first winter Caspian Gull if the head was white. I have concluded "just a Herring Gull".

The Flash: 10:35 – 11:30

(277th visit of the year)

Bird notes:
- as yesterday most of the Greylag Geese were inside the island and hard to count. Two white feral geese were with them again.
- a pair of (Common) Teal were lurking alongside the island again.
- numbers of Tufted Duck and Pochard "best effort" with many birds continually diving and moving around.
- a Great Crested Grebe was new in. Which reminds me I forgot to note the calling Little Grebe yesterday. I did not see or hear it today.
- an adult Yellow-legged Gull is a species I do not see here very often. One on 27 January was my only other record this year.

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

Noted on / around the water:
- 7 Canada Geese
- >40 Greylag Geese
- 2 mainly white feral geese
- 6 + 2 (1 brood) Mute Swans
- 38 (22♂) Mallard
- *2 (1♂) Common Teal
- 13 (>7♂) Pochard
- 83 (>52♂) Tufted Duck
- 13 Moorhens
- 89 Coots
- *1 Great Crested Grebe
- 93 Black-headed Gulls
- *3 Herring Gulls: one adult; two second winters
- *1 Yellow-legged Gull: adult
- 1 Grey Heron

Noted elsewhere:
- just one unidentified fly around the Ivy bank. Warm-enough but too cloudy and windy.

A challenge: spot the pair of (Common) Teal.

The newly-arrived Great Crested Grebe. My last sighting here was of two birds on 14 November.

The very clean-headed adult gull on the left must be a Yellow-legged Gull. Note how much darker it looks than the adult winter Herring Gull on the right. In this photo it almost looks dark-enough to be a Lesser Black-backed Gull: in 'real life' it was too pale. On average Yellow-legs should be slightly smaller than Herrings with males of both species averaging larger than females. That would suggest we are looking at a male Yellow-leg and a female Herring. But "on average"...

Plane of the day: this is the West Midlands Air Ambulance on another mission from its base alongside RAF Cosford. This Airbus Helicopters EC 145T2 (originally designated a MBB-Bk 117 D-2) was away on annual maintenance for much of November with one of the 'spare' air ambulance helicopters from Gloucestershire Airport substituting.
