Priorslee Lake The Flash

Note order

1.0°C: patchy cloud clearing away. Frost and ice. Calm. Moderate visibility but often poor at the lake.

[Sunrise: 08:12 GMT]

* = a photo today

Fog and ice suggested a delayed start would be appropriate.

Priorslee Lake: 10:50 – 11:30

(17th visit of the year)

>50% thin ice.

Viewing only from the dam area

Bird notes:
- Ice around the edges seemed to have forced the two Little Grebes out to edge of the reeds – still necessary to look hard!
- Most of the gulls were 'hanging about' with very few arriving or departing

Birds noted flying over here:
- 1 Common Buzzard
- 2 Ravens

Counts from the lake area:
- 2 + 3 (1) Mute Swans
- 2 (2♂) Gadwall still

The Flash: 09:55 – 10:45

(16th visit of the year)

>75% thin ice.

Bird notes:
- Two pairs of Teal were tucked up against the island.
- The drake Shoveler out on the remaining open water. Its fourth day here.
- Pochard apparently gone.
- No Great Crested Grebe again.
- Two Cormorants lurking on the island: one disappeared in to the water – brrrr!

On the street lamps:
Nothing on any of them

Also noted:

- 1 Brown Rat

With light at a different angle the drake Shoveler's head almost looks green – as it should.

Black-headed Gulls seem quite happy to stand on the ice.

In the middle a first winter Herring Gull showing pale grey at the very top of the back. A Coot lurks behind the left-hand of the two Black-headed Gulls: this gull is a winter adult with the scarlet bill while the other is a first winter with an orange base to its bill and brown in the folded wing. Two sleeping Canada Geese at the back.

It eventually flew off coming a lot closer but not showing me its upper-wing pattern, useful for eliminating the remote possibility of Yellow-legged or Caspian Gulls. From this angle a first-winter Lesser Black-backed Gull would have a much more strongly marked underwing.

Why are the large gulls so often a long way away. On the basis of the pale eye and the pale tip to the bill with a strong dark mark across it I think this is a third winter Herring Gull. The small amount of brown in the folded wing tends to confirm this though birds age at different rates and separation of second and third winter birds is not always straightforward.

Is this the same adult Lesser Black-backed Gull that was standing arrogantly on a roof yesterday?

 This Moorhen is stretching a wing out to aid its balance on the ice. Note the long nails on its long toes.

Today's fly-over. A Singapore Airlines Cargo Boeing 747-400 Jumbo on its way from Los Angeles to Brussels. The rear of the fuselage is wrapped in gold-coloured paint with dark blue above it. It was at 35000' - not bad for six and half miles away!
