(22nd visit of the year)

New Bird Species
Another long overdue bird species to add to my 2024 bird species list from here: a group of c.80 Starlings flew over obviously outbound from a local roost. Species #58.

Other bird notes:
- Once again one of the Mute Swan cygnets was sleeping well apart and it stayed some distance away from its parents and sibling throughout.
- A Great Crested Grebe was a new arrival since yesterday.
- Black-headed Gulls were late arriving with the first group of c.90 birds at 07:45. By 07:50 they had already begun to disperse.
- All the overflying Herring Gulls were heading South: the fewer Lesser Black-backed Gulls were heading north-west.
- *In addition to the eight Redwings seen leaving a roost in the north-east area there were 13 in trees alongside Teece Drive much later.

Counts of birds noted flying over:
- 48 Canada Geese: outbound in nine groups
- 5 Greylag Geese: duo outbound; trio inbound
- 22 Wood Pigeons
- 15 Herring Gulls
- 6 Lesser Black-backed Gulls
- 16 Jackdaws
- 12 Rooks
- c.80 Starlings
- 2 Pied Wagtails

Birds seen leaving roosts around the lake:
- 8 Redwings

Counts from the lake area:
- 2 + 2 Mute Swans
- 12 Canada Geese: arrived inbound as a duo and octet
- 11 (6♂) Mallard
- 31 (15♂) Tufted Duck
- 8 Moorhens
- Coots not counted
- *1 Great Crested Grebe
- c.175 Black-headed Gulls
- 1 Herring Gull
- 1 Cormorant: arrived
- 2 Grey Heron: arrived separately; one chased away

Noted on or around the street lamp poles pre-dawn:

Moths:
- *1 Pale Brindled Beauty Phigalia pilosaria: same place as yesterday
- 1 Winter Moth Operophtera brumata

Flies:
- 1 small male plumed midge
- 1 winter cranefly

Beetles:
- *1 beetle sp., probably a Rhyzobius ladybird and perhaps Meadow Ladybird R. litura.

Other insects:
- *1 springtail Tomocerus vulgaris
- *1 globular springtail perhaps a Dicyrtoma sp.

Spiders:
- *1 Stout Sac Spider Clubiona sp.

New since yesterday was this Great Crested Grebe.

In equally dull light was this Redwing...

...allowing an unusually close approach.

The same Pale Brindled Beauty moth Phigalia pilosaria in the same place as yesterday though it has shuffled about slightly.

A tiny beetle that I thought at the time looked ladybird-shaped. One of the suggestions from Obsidentify was a Rhyzobius ladybird and looking at those on the NatureSpot web site it is perhaps Meadow Ladybird R. litura, though none of the species are noted as active in Winter.

A springtail Tomocerus vulgaris.

Obsidentify's suggestion for this was a globular springtail of the Dicyrtoma group. The shape is right though none of the photos on the NatureSpot web site show the bristles just visible at the tip of the abdomen on this example.

The shape of the tip of the abdomen identifies this as a Stout Sac Spider Clubiona sp. Individual species are not separable from photos.

The Flash: 09:20– 10:05

(21st visit of the year)

New Bird Species
A new species for my 2024 bird list from here as well: two Redwings flew over. a species I was surprised not to see during the recent icy period. Species #46.

Other bird notes:
- Neither of the Canada Geese was the bird with the 'angel wing' deformity. So where was it hiding?
- Common Teal not located.
- At least 30 finches flew into the Alders on the island: a mix of Siskins and Goldfinches.

Bird(s) noted flying over here:
- 2 Redwings

Noted on / around the water:
- 2 Canada Geese
- 2 + 4 Mute Swans
- 2 (1♂) Gadwall
- 44 (29♂) Mallard
- 1 (1♂) all-white feral duck
- 3 (2♂) Pochard
- 35 (16♂) Tufted Duck
- *1 (0♂) Goosander
- 16 Moorhens
- Coots not counted
- 1 Great Crested Grebe
- *15 Black-headed Gulls
- 1 Lesser Black-backed Gull: adult

Elsewhere:
Nothing of special interest

A new arrival here since yesterday was this duck Goosander.

"It is no good you looking angrily at me. I was standing on the bridge when you flew on to the hand-rail". A belligerent Black-headed Gull.
