Priorslee Lake and The Flash

5.0°C > 4.0°C: Low cloud with light drizzle. Moderate / fresh E wind. Good visibility.

Sunrise: 08:21 GMT

* = a photo today

After two days of fog some changes to note:
- at the lake new in were a duck Teal and two drake Pochard
- at The Flash the largest party of geese I have seen for many months arrived: these included paired Canada and Greylag Geese and their three hybrid offspring. There was also a drake Shoveler and a rather small all-white duck with a yellow bill. I could not find any Teal or Pochard.

Priorslee Lake: 06:45 – 09:15

(298th visit of the year)

Other bird notes:
- The first Black-headed Gulls arrived at 07:27. Two blue-light ambulances probably ruined their wash and brush up just as much as the ambulances were probably ruining a few people's Christmas. Eventually at least 500 arrived.

Overhead:
- 1 Wood Pigeons
- 1 Common Buzzard
- 4 Herring Gull
- 9 Lesser Black-backed Gulls
- 75 Jackdaws
- 1 Raven
- 8 Pied Wagtails heard
- 1 Linnet

- 2 (1♂) Gadwall again

- 49 Coots
- >500 Black-headed Gulls
- 1 Great Black-backed Gull
- 27 Herring Gull
- 1 Yellow-legged Gull
- 41 Lesser Black-backed Gulls

Around the damp lamps:

Moths:
- 1 male Winter Moth (Operophtera brumata)
- 1 male Mottled Umber (Erranis defoliaria): mostly eaten!

The only photo I took on this very dull morning before I put the camera away in the dry. A slightly better view of the male Mottled Umber (Erranis defoliaria) that is being / has been eaten.

The Flash: 09:20 – 10:00

(273rd visit of the year)

Other bird notes:
- The three off-spring of the paired Canada and Greylag Geese were presumably this year's immatures. I doubt the quartet of off-spring seen in 2020 would still be closely accompanying their parents.
- The all-white duck (presumed feral) was lurking on the island not giving clear views. The light was too poor to try a photo.
- Many fewer Tufted Ducks: perhaps they were at the lake?
- At least three Siskins were drinking from puddles in the path between the two footbridges.

Birds noted flying over here:
- 1 Herring Gull
- 6 Lesser Black-backed Gulls

On /around the water:
- 70 Canada Geese: 61 of these flew in
