15.0°C > 17.0°C: Early patchy cloud; some mist over the fields. Sunny for a while then clouds approaching from the West ahead of rain. Light mainly southerly breeze. Very good visibility.
Sunrise: 06:49 BST
+ = my first sighting of this species at this site this year.
++ = new species for me at this site.
* = a species photographed today
Highlights today were:
- A / the Cetti's Warbler gave a single song along the North side of the lake at 06:30. Probably explains why I have not recorded it for a while as during the Summer it favoured the South side (and may even have bred). My last confirmed record of this species here was on 16 August (although I did hear a brief single note which sounded promising on 9 September).
- The first Siskin of at The Flash flew over (after the first at the lake yesterday)
Priorslee Balancing Lake: 05:20 – 09:10
(191st visit of the year)
Bird notes:
- The higher Coot number is probably a reflection of the better visibility down the whole length of the water rather than any real increase.
- Eight of the early unidentified large gulls flying over were unusually in a skein heading North. Usually birds pass between East and South. [is 'skein' applied to a formation of gulls as well as geese?']
- Just three Pied Wagtails were on the football field at 09:05. A few had been heard overhead earlier.
Counts of birds noted flying over:
- 48 Canada Geese: inbound in four groups
- 7 Feral Pigeon: a septet
- 71 Wood Pigeons
- 1 Herring Gull
- 4 Lesser Black-backed Gulls: ages not determined
- 28 unidentified large gulls
- 6 Jackdaws
- 11 Rooks
- 3 Pied Wagtails
Warblers noted (the number singing in brackets):
- 1 (1) Cetti's Warbler
- *15 (6) Chiffchaffs
- 2 (0) Blackcaps
Hirundines etc., noted:
- 2 House Martins at least c.08:55
Counts from the lake area:
- 2 + 2 Mute Swans
- 7 (3♂) Mallard
- 5 Moorhens
- 107 Coots
- 2 Great Crested Grebes
- c.225 Black-headed Gulls on the football field c.06:50. No more that 20 at any one time seen on the lake
- 6 Herring Gulls: one adult and five first winters
- *29 Lesser Black-backed Gulls: not all ages determined with majority being first winters
- 1 Kingfisher: seen numerous times again
On or around the street lamp poles at dawn:
Moths:
- none
- none
Other things:
- 1 plumed midge Chironomus plumosus
- 1 plumed midge Microtendipes pedellus
- *1 Spotted-winged Drosophila (Drosophila suzukii)
- 3 springtails Pogonognathellus longicornis
- 1 Alder Leaf Beetle (Agelastica alni)
- 3 spiders Clubiona sp.
- *2 Bridge Orb-web Spiders (Larinioides sclopetarius)
- 3 male Leiobunum rotundum harvestman
- 1 unidentified slug sp.
[NB: I am trying to adopt a standard presentation for insects etc. Where there is an accepted vernacular name the (scientific name) will be appended in brackets.

Around the sailing club HQ
- 1 plumed midge Microtendipes pedellus
- 1 wood gnat Sylvicola fenestralis
- 1 Garden Spider (Araneus diadematus)
- several Bridge Orb-web Spiders (Larinioides sclopetarius)
- many slugs and snails
Also pre-dawn:
- three species of bat noted. The usual pipistrelle-type were around the North side shoreline. They were joined for a while by a much larger bat which flew differently from the 'large direct-flying' species that I see frequently and was also present today. I need a bat detector!
Noted later: my 'Winter timing' means I leave the lake before many insects are around.

Taken at the time the sun should have risen, and probably did. No colour.

As does an adult Lesser Black-backed Gull showing blood at the base of its bill. The legs of adults are yellow. They do not look particularly yellow here but there is a slight contrast with the pink feet.

A 'no publicity' Chiffchaff. All the same bird.
I am unable to work out what the Bridge Orb-web Spider (Larinioides sclopetarius) has wrapped up.

My first Dock Bug (Coreus marginatus) here this year.
I have previously shown this size of Common Green Shieldbugs instar (Palomena prasina).
I do not often see this earlier stage instar.
I'll say it again. You WILL learn to like spiders. A Garden Spider (Araneus diadematus)
