Priorslee Balancing Lake and The Flash

4.0°C > 6.0°C: Cloudy and often very dull. Rain starting as I arrived. Ceased c.07:30 and then occasional drizzle. South-easterly wind breeze. Moderate visibility at best.

Sunrise: 08:22 GMT still
* = a species photographed today

Priorslee Balancing Lake: 06:35 – 09:25

(275th visit of the year)

One that got away. At 07:15 while I was avoiding the rain inside the sailing club shelter a large pale shape flew past. My first thought it was a gull: not so – too large, too early and on its own which would be unusual. Then: was I looking at the pale parts of a passing Grey Heron? Well: the flight seemed less laboured than a heron and it did not call which would have been unusual. An owl perhaps? I will never know as I saw nothing more.

Other bird notes:
- A Water Rail was seen in a ditch feeding in to the lake. I am always surprised how small these are, much smaller than a Moorhen. I nearly overlooked it as it was exactly where yesterday I had seen a blackbird bathing in a muddy pool.
- It was too dull to make a full count of the Coots. I did not there were 54 on the south-west grass at dawn.
- The first 18 Black-headed Gulls did not arrive until 07:50. No more than 200 were present at any one time.
- A few large gulls settled on the water briefly. Unexpectedly these included two Great Black-backed Gulls.
- No Cormorants here or at The Flash today.

The (semi) nocturnal community on or around the street lamp poles pre-dawn:
The rain seemed to have sent most things scurrying for cover.

Moths:
- 1 male Winter Moth Operophtera brumata
- *1 male Mottled Umber Erranis defoliaria: same place for the third day

Flies:
- several small plumed midges

Other insects:

In the Sailing Club Shelter
Trapped by the rain in the shelter I looked again for the spiders lurking there:
- *1 Stout Sac Spider Clubiona sp.
- *1 Walnut Orb Weaver Nuctenea umbratica

On the Teece Drive fence:
Nothing noted.

On the left an adult Great Black-backed Gull; on the right the coarse markings of a first winter Great Black-backed Gull; the middle bird is an immature (second winter?) Herring Gull.

A better photo of the male Mottled Umber Erranis defoliaria. There were not too many things on the street lamp poles in the rain and I was reluctant to get the camera wet.

Today's globular springtail.

In the sailing club shelter I noted this Stout Sac Spider Clubiona sp. I think the first I have seen in the shelter.

Also in that shelter was this Walnut Orb Weaver spider Nuctenea umbratica.

Nothing noted

A lot of work on the photo editor managed to rescue a 'black cat in the coal cellar' shot of a dark brown Treecreeper against a dark brown tree trunk in dull conditions.

Better have another one!
