13.0°C > 15.0°C: Early broken cloud soon disappeared with low cloud and light rain for a while after 06:45. Dried up later. Always clearer to the East though staying dull here. Light SE breeze. Good visibility.
Sunrise: 06:32 BST

Priorslee Lake: 05:15 – 09:05
(191st visit of the year)
Bird notes:
- A fourth Gadwall this morning: another duck. Two of these seen in flight. Later I could not locate any of them.
- The visibility was not good with a low light level. I did a sweep count of Great Crested Grebes and logged 26. This is more than the 12 + 10 juveniles recorded recently. I cannot ascribe the difference to adult / juvenile.
- Another possible Woodcock record when an appropriate-sized bird nearly took my nose off as it flew past at 05:55.
- The 70 'large gulls' all flew over before 06:15 when it was too dark to ascribe them to species. They were likely almost all Lesser Black-backed Gulls.
- A Tawny Owl was calling from the Ricoh copse c.05:20.
Birds noted flying over here:
- 10 Canada Geese: outbound in two groups
- 2 Tufted Ducks: sexes not determined

Noted on / around the street lamp poles pre-dawn
Another bumper haul of strange things
Moths:
- *1 Small Fan-footed Wave (Idaea biselata)
This adult Black-headed Gull has found something to pick up and play with. Note how short each black-tipped outer primary is. It is the last primary feather to regrow as part of the annual moult.
Herring Gulls have been rather few and far between as yet this Autumn. These two dropped in together. An adult on the left with the pale eye. The bird on the right is a first summer / second winter bird.
Another first winter Yellow-legged Gull candidate. Unlike yesterday's bird this one shows a pale head as well as the paler inner primaries.
Two adult Lesser Black-backed Gulls. These are of different races breeding in different parts of Europe. The back bird has the back (mantle) as dark as the folded wing-tips and is of the race intermedius that breeds in Scandinavia. The nearer bird with the mantle paler than the wing-tips is of the race graellsii, breeding around the UK. Separation is not always easy (or possible) as the angle of the light can change perception and hybrid birds do occur.
This is a very worn moth with the characteristic shape of one of the 'wave' species. I think it is a Small Fan-footed Wave (Idaea biselata).
My best guess on this is a sawfly larva though I have been unable to match it with photos on the internet.
And there they go. I wonder where to? They will not be welcomed by the residents at the Balancing Lake that's for sure.
An unusual view of the drake Gadwall. It seems to think it is a Mallard and takes part in all their scrambles for food.
What could be smarter? Here he is giving his characteristic rather creaky call-note. The chestnut in the wing is just about visible. Who designed those feathers with white tips to give the vermiculated effect? Full marks to them.
A juvenile Moorhen clambering over willowherb. Moorhens are adept climbers and are often to be seen inside bushes looking for food.
A Common Carder Bee (Bombus pascuorum) with its tongue in a Water Mint (Mentha aquatica) floret. My logs suggest I have not recorded this plant here previously.
When I first noticed what turned out to be a small Dicranopalpus ramosus/caudatus harvestman I thought it was a small beetle: I did not see its legs. You can get some idea of its small size because it is sitting on the leaf of a Stinging Nettle (Urtica dioica).
This Nipplewort (Lapsana communis) has almost finished flowering. One of many confusing yellow flowered plants.
A Common Plume moth (Emmelina monodactyla). Beyond the characteristic plume moth shape this is identified by its lack of markings.
This moth is a Red-green Carpet (Chloroclysta siterata) even though there is not much sign of any red tones to this specimen. It was on the roof of the tunnel. Both these moths were new for the year here and improbably they bring the number of different species of moth that I have found in the tunnel during 2022 to 26.
Common Crane-fly (Tipula oleracea) earns its 'common' moniker in Autumn when it is abundant everywhere. This is a female with the pointed abdomen (her ovipositor). She lays her eggs in the ground. When they hatch the larvae feed on grass roots before metamorphosing and leaving 'leather jackets' sticking out of the ground as evidence of their emergence.

- Alder Leaf Beetle (Agelastica alni)
Nothing special, just a pleasing pose from two Great Crested Grebes.
Whereas this looks as if it might be yesterday's bird.
A rather clearer photo of a midge, in this instance the plumed midge Chironomus plumosus. I have two cameras and take just one on any one morning. One camera – this one – is better at close-ups, especially with flash. The other is better for flight shots. I refuse to lug two about.

The Flash: 09:10 – 10:10
(187th visit of the year)
Bird notes:
- Three of the adult Mute Swans went for a fly around at 09:40, heading way to the West before returning overhead and then disappearing to the South not to return before I departed at 10:10.
- A bit of a puzzle as to why there are so many Cormorants here at the moment. Most of them are not fishing at the time I am present. Perhaps they arrive early, feed on the small fry and then sit around digesting their food.
Birds noted flying over here:
- 2 Jackdaws: singles
Warblers noted:
- 1 Chiffchaff

Two of the three adult Mute Swans start their flight.
All three flying around after gaining height.
Probably a garden escape but good to see: flowers of Honeysuckle (Lonicera sp.).
Another yellow flowering plant is this Smooth Sow-thistle or Milk Thistle (Sonchus oleraceus).
I noted this plant, White Dead-Nettle (Lamium album), in flower on 01 January and I have noted a few flowers almost ever since. It seems to have had a new lease of life recently.
