Priorslee Lake and The Flash

Priorslee Lake:  07:05 – 09:25
The Flash:  09:30 – 10:25

10.0°C:  Broken cloud with sunny spells after a few early light sprinkles. Light / moderate S wind. Very good visibility.

Sunrise: 08:18 GMT

Priorslee Lake:  07:05 – 09:25

(288th visit of the year)

Gull notes:
- c.750 gulls on the water at 07:20. Seemed to be (almost?) all large gulls.
- c.1100 Black-headed Gulls streamed in from the W between 07:30 and 07:35. By far my largest count of this species at this site this year.
- 81 large gulls were noted flying over before 07:40 when ....
- ... all gulls started to leave. They were swirling around in all directions making it impossible to separate birds departing from any birds that might have been flying over.
- By 08:00 fewer than 150 gulls remained. A few large gulls started to arrive (return?). None stayed long.
- Later a reasonable passage of gulls NW overhead. A few Black-headed Gulls with, mainly, Lesser Black-backed Gulls. These all assumed to be ‘new’ birds.

Other bird notes:
- The fifth Mute Swan cygnet was again on its own much of the time. Only three of the other cygnets were with their parents. The remaining cygnet eventually joined up with #5.
- Rather fewer Tufted Duck (and Pochard). Whether due to the ice of the last few mornings or the very discoloured water is hard to say. I would favour the former as there were fewer Tufted Duck at The Flash as well and the water there was not discoloured.
- Two drake Goosanders seen flying E singly. The first could possibly have been leaving the lake though I had not seen it on the water.
- Accurate Coot count difficult – many birds bunched up on the SW grass.
- Mistle Thrush seen and heard in song again.
- Two Reed Buntings heard calling at the W end but none seen to leave a roost here.

No other sightings

Not a picture I expected to take when I looked at the weather forecast for the morning. Now seven days (and two hours) since full moon so half moon is about right.

Someone is thinking Spring is not far away ....

These two Great Crested Grebes getting ready to pair up. The bird on the right has its bill open. I did not hear any calls.

Where it runs in to the lake the Wesley Brook needs to be renamed the Brown River.

The Wesley Brook itself as it runs alongside Teece Drive is clear.

The discolouration is all from the various drains under the academy and surrounding land.

The Flash:  09:30 – 10:25

(273rd visit of the year)

Bird notes from here:
- Kingfisher again noisy and persisted in flying around when I had vegetation in front of me. So no photos.
- Song Thrush again in intermittent song.

Birds noted flying over / near The Flash:
- 1 Sparrowhawk
- 6 Lesser Black-backed Gulls
- 1 Herring Gull
- 15 Wood Pigeons

Counts from the water:
- 3 Mute Swans as ever
- 2 Canada Geese: the usual two
- 33 (20♂) Mallard
- 6 (6♂) Pochard again
- 16 (8♂) Tufted Duck
- 8 (1♂) Goosander
- 1 Grey Heron
- 2 Great Crested Grebes again
- 6 Moorhens
- 12 Coots again
- 54 Black-headed Gulls
- 1 Lesser Black-backed Gull: adult
- 1 Kingfisher

On a lamp pole in squirrel alley:
        - 1 Winter Moth (Operophtera brumata)

On a lamp pole elsewhere
        - 1 probable Garden Spider (Araneus diadematus)


I am fairly certain that this is a Garden Spider (Araneus diadematus). The diagnostic ‘white cross’ mark is, I think, over the shoulder and not visible from here – just as two of the legs are not visible.
