7.0°C > 6.0°C: Early sprinkles of showery rain. Cleared to scattered clouds with some sun. Moderate / fresh WSW wind. Very good visibility.
Sunrise: 08:22 GMT still
* = a photo from today.
Priorslee Lake: 06:50 – 09:35
(263rd visit of the year)
Two highlights:
- Seven Lapwings circled over at 08:50. Apparently only my second record of this declining species here this year. My previous record was on 01 January!
- *A Common Kestrel was seen briefly at 08:45, strangely hovering above the new housing development to the East of Castle Farm Way. Also only my second record here this year of another declining species. My previous record was on 14 March.
And two that got away and are not included in any totals below:
- Eight ducks were flying around c.07:25. They were about the size of Mallard but I could not hear the distinctive wing noise that this species gives in flight so they remain unidentified.
- At more or less the same time what might have been either a Common Snipe or a Woodcock dropped in to sedges / brambles beside the small copse along the South side. I had a search later, staying on the pathways, but could see nothing.
Other bird notes:
- At least 75 Black-headed Gulls were on the water by 07:25 with a few more arriving, unusually, from the South. These had all gone by 07:35. Birds then started to arrive from their usual westerly direction after 07:40 with at least 150 noted. Were these the same birds? Almost all had gone again by 08:00.
- There is currently almost no early arrival (or early passage) of large gulls. For several winter-periods recently a roost on factory roofs in Hortonwood has delivered up to 200 birds to bathe and drink before they set off for the day scavenging food. In the absence of these gulls on the water then later passing gulls seem disinclined to drop in.
- A Mistle Thrush was seen in the south-east trees before flying off East giving it football-rattle call notes [does anyone know what a football-rattle is these days?]
- A single Reed Bunting was heard calling from the usual West end roost site. Two other roosting birds flew off from the South side reeds unusually.

Seen later:
Nothing of note
A slightly different view. It is just about possible to make out some streaking along the flanks.
A species I do not often photograph: they are usually moving around too quickly. Not this Blue Tit.
At the time I thought this moth was a pale and poorly-marked Mottled Umber moth but looking at the photo I realise it is my first Northern Winter Moth (Operophtera fagata) for several years. This species is larger and typically more strongly-marked than Winter Moth (O. brumata). Perhaps more importantly the underwings tend to extend beyond the upperwings at rest, as here. It takes my moth species total for the year to 95.

Nothing noted
One of the five Greylag Geese that arrived.
The cob Mute Swan was in Canada Goose chasing mode.
"What a clever swan am I"
I hope his partner and the children are impressed.
The feisty Coots were at it again.
An apparently one-legged adult winter Black-headed Gull.
And a headless first winter Black-headed Gull! First winter because of the black band on the tail tip.
Here it is resurfacing where the brown in the wings confirm the age.
No. It hasn't got a drip on its bill. It is the tip of the left wing just showing as this adult flies by.
This one is OK.
A Wood Pigeon takes off
Flapping hard to lift its not inconsiderable bulk.
Here it is dashing past. Upperwing and...
...underwing.
