8.0°C > 10.0°C: A mixture. Cloud from overnight rain soon clearing to E and then clear for a while. Another area of cloud arrived before that too cleared to thin high overcast. Light W / SW wind. Very good visibility.
Sunrise: 07:28 GMT
* = a photo today.
Priorslee Lake: 06:02 – 09:23
(248th visit of the year)
Bird notes:
- In addition to the fly-over Goosanders a drake was seen leaving the lake at 07:30.
- Not sure where the early arriving Lesser Black-backed Gulls came from: they dropped from high overhead and I saw none overflying at that time to provide a clue. Unusually there were two immature Herring Gulls with them. Later arrivals were part of a small but steady E -> W passage with some birds stopping off for a while. The usual few gull puzzles.
- Very strange behaviour from Wood Pigeons. A larger than usual number were flying fast W early on, low-down and not in groups. Therefore they did not appear to be migrants. The just before 08:00 several large groups, one of c.130 birds, were noted heading N - yes N! In all I logged c.300. Whilst a few were still heading N several larger groups appeared flying S / SW, two of which both contained over 250 birds. All this within c.15 minutes. Only a few singles seen afterwards.
- Jackdaws very difficult to count today. They were in several concurrent scattered high-flying groups passing both to my left and right as well as overhead. Later two birds were seen, unusually, strutting around the football field.

Did I have trouble with some of the gulls this morning? I did. The near adult bird on the right in real life had a mantle that was clearly paler than a Lesser Black-backed Gull and therefore a candidate Yellow-legged Gull. A very strange bill with solid dark area across the middle of both mandibles - hence my assumption that it is not a full adult.
I think this is 'just' a first-winter Herring Gull though the head seemed rather pale. I have ascribed it on the basis of the strength of the barring on the under-tail but am willing to be told otherwise.
More grey on the back indicates this is a second-winter gull. It has a rather pale head and looks suspiciously like one of the Caspian Gulls identified previously.
The same bird at the back with a paler second-winter Herring Gull in the foreground. Gull profiles can vary greatly depending on how they hold themselves but the putative Caspian looks longer necked and smaller headed.
This illustrates the challenge of accurately determining the mantle tone of gulls. The same bird turned a fraction to catch the light from a different angle and it looks paler.
And here is the same second-winter Herring Gull for comparison. Shows a stouter-looking, shorter neck.
This is frustrating. I can recall seeing something like this previously and managing some type of identification. But I have forgotten. So I had to start again. My best guess is a species of springtail. As one of the most common Pogonognathellus longicornis seems possible. It sure has a longicornis.

(232nd visit of the year)
Bird notes:
- The adult pen Mute Swan with the green Darvic ring was alone on the island and likely the bird that has been sulking there for three days. I assume this was the pen reportedly taken in to care for a while. The cob was sometimes with what I believe to be his 2018 daughter (thus also a pen). He was occasionally on his own. The cygnets were all together somewhere else.
- The immature Herring Gull stayed inside the island and was difficult to age. I later saw a first-winter circling overhead which might have been the same bird.
Birds noted flying over / near The Flash:
- 1 Lesser Black-backed Gull: adult
- 5 Feral Pigeons: two singles & trio
- 8 Wood Pigeon together
- 47 Jackdaw
Counts from the water:
- 3 + 7 (1 brood) Mute Swans
- 25 Canada Geese: seven of these arrived
- 35 (20♂) Mallard
- 3 (2♂) Pochard
- 60 (?♂) Tufted Duck exactly
- 13 (>2♂) Goosanders
- 1 Grey Heron again
- 2 Great Crested Grebes as ever
- 12 Moorhens
- 42 Coots
- 63 Black-headed Gulls
- 1 Herring Gull: first-winter
On the lamp poles.
Nothing
Around the Ivy
- >30 Common Wasps (Vespula vulgaris)
- 1 drone fly sp.: seen too briefly to ID
- many 'flies'
Of interest elsewhere:
- active Honey Bees (Apis mellifera) at their nest site. I would have thought it was too cold (10°C) with only rather watery sun to tempt them out.
- 3 Grey Squirrels
