Priorslee Balancing Lake and The Flash

10.0°C > 11.0°C: Much cloud especially to the East. A very few good breaks. Moderate westerly wind gusting fresh, even strong at times. Very good visibility.

Sunrise: 07:48 GMT

* = a species photographed today

Priorslee Balancing Lake: 06:30 – 09:20

(33rd visit of the year)

New Bird Species
Highlight today was a Tawny Owl sitting on the fence alongside the Ricoh copse as I arrived. It was too dark to think about a photo and anyway it flew off into the trees before I could gather myself. Bird species #61 for me here this year.

Other bird notes:
- no sign of 'our' duck Goosander.
- a Great Crested Grebe seen once and briefly lurking in the reeds in the north-west area. Could it have been hiding here unseen for many days?
- Black-headed Gulls were much later arriving today and in slightly smaller numbers.
- so where were all the large gulls today? After over 500 yesterday just a handful was noted.
- a Stock Dove was heard calling from the North wood.

Counts of birds noted flying over:
- 4 Canada Geese: two pairs outbound
- 7 Wood Pigeons
- 5 Lesser Black-backed Gulls
- 1 Cormorant
- 61 Jackdaws
- 27 Rooks

Birds seen leaving roosts around the lake:
None

Noted on or around the street lamp poles pre-dawn

Moths:
- none

Flies:
- *1 winter cranefly Trichocera sp.
- *1 gnat sp.

Beetles:
- *1 7 Spot Ladybird Coccinella 7-punctata
- *2 other beetles to be identified (perhaps)

Other insects
- *1 springtail Orchestella cincta
- *1 smaller springtail possibly Orchestella flavescens

Spiders:
- *1 Long-jawed Orb-web Spider Tetragnatha sp.
- *1 Missing Sector Orb-web Spider Zygiella x-notata [also called Silver-sided Sector Spider]

Noted later:
- *first flower of Blackthorn Prunus spinosa [previous first dates were 25 February in 2023 and 22 February in 2022]

Extensive cloud to the East precluded any red sunrise. This weak colour was visible looking South.

Whereas looking West the sky was, at this time, almost cloudless.

Just a few of the Black-headed Gulls here this morning. The bird on the right has the full dark hood of its breeding plumage: the bird on the extreme left is starting its head moult. The happens remarkably quickly.

A Cormorant on its favourite perch. It seemed to have no trouble standing there despite the gusty wind.

The small head identifies this as a cranefly. It is one of the winter craneflies Trichocera sp.

An unidentified winter gnat.

A 7 Spot Ladybird Coccinella 7-punctata tempted out of hibernation by the warm spell.

One of two unidentified beetles I found this morning.

And here is the other one. I am not sure why I seem to be seeing so many beetles at the moment. Am I 'getting my eye in'? Or are there more because of the mild conditions?

This springtail was identified by Obsidentify as Orchestella cincta. Looks a good call from pictures on the Naturespot web site.

Obsidentify gave me Orchestella flavescens for this smaller springtail. I cannot find any illustrations of this species on the web: it does look to be one of that group.

A Long-jawed Orb-web Spider Tetragnatha sp.

A Missing Sector Orb-web Spider Zygiella x-notata [also called Silver-sided Sector Spider]

The very first flower of Blackthorn Prunus spinosa.

The Flash: 09:25– 10:25

(32nd visit of the year)

Highlight here was two (at least) Kingfishers making lots of noise and chasing around the top end, across the top field and around the houses. They also perched from time to time but could I find them where they were when they were not being flying blue arrows?

Other bird notes:
- the pen Mute Swan was on her own on the island, perhaps checking out potential nest sites?
- I could not locate the long-staying pair of Gadwall; and most of yesterday's Pochard also seemed to have moved.
- neither did I note the all-white feral duck. Perhaps I was concentrating on the Kingfishers.
- both Great Crested Grebes noted.
- a Goldcrest heard in song for the first time this year.

Bird(s) noted flying over here:
- 4 Jackdaws

Noted on / around the water:
- 21 Canada Geese
- 2 + 4 Mute Swans
- 34 (23♂) Mallard
- 1 (1♂) all-white feral duck
- 1 (1♂) Pochard
- 79 (44♂) Tufted Duck
- 14 Moorhens
- 47 Coots
- 2 Great Crested Grebes
- 43 Black-headed Gulls
- 3 Herring Gulls: all immatures, not aged
- *2 Kingfishers

Of note later:
- first leaves of Hawthorn Crataegus monogyna

 I did note that the Kingfishers were flying like blue arrows!

Some days since a Robin posed for me.

"What is that over there?"
