(8th visit of the year)

A very quiet morning – apart from seven noisy singing Song Thrushes at the lake.

Other bird notes:
- Several groups of large gulls flew directly overhead while it was still too dark to ID them.
- Another morning with a huge mixed party of Rooks and Jackdaws high overhead – as well as the usual express groups of Jackdaws passing low across the area.
- Two Starlings leaving a roost around the lake were unexpected.
- A Reed Bunting was in song at the W end. Seems an early date to me.

- 9 Lesser Black-backed Gulls only
- 69 unidentified large gulls

- 2 different unidentified spider sp.

None

Not my best-ever photo of a Reed Bunting but my first of a singing male in January.

A bonanza on the lamps after a mild night. This is my first Early Moth (Theria primaria) of the year. Not dissimilar to Winter Moth (Operophtera brumata) – same size and colouration. A subtle difference in wing shape. However the clue is the wavy sub-terminal band across the forewings.

Now here is something I did not expect in January – quite obviously a weevil and very tiny. I suspect Apion frumentarium, a seed weevil, though it should not be active at this date.

Three for the price of one: bottom left is a Nursery Web Spider (Pisaura mirabilis); on the right a Common European Earwig (Forficula auricularia) – a male as it has curved ‘pincers’; and at the top an unidentified small spider.

I also have had to give up with this spider. It is too elongated to be another Nursery Web Spider and I thought it might be one of the stretch spiders. However the palps are too prominent. Pass

This is the harvestman Dicranopalpus ramosus. Identify this species by the obviously thicker basal part of the legs.

A small group of Tufted Duck went for a fly-about. Three ducks with a drake at the rear – see how the white on the flanks is clearly delineated and extends right in to the ‘arm-pits’.

Trench Middle Pool:  10:45 – 11:25

(3rd visit of the year)

Highlights
- The Pink-footed Goose again flew in with the smaller number of Greylag Geese.
- The Yellow-legged Gull also made it over from Trench Lock Pool where I saw it earlier but showed worrying pink legs in photos I took of it.

Other notes from here:
- Food had been provided at the E end of the embankment, away from the island, and this probably allowed a more accurate count of the number of Coots present as they left cover to scramble for the goodies.

None

- 12 (4♂) Tufted Duck
- 3 (2♂) Goosanders
- 1 Cormorant again

- 3 Herring Gulls: all first-winters
- 1 Yellow-legged Gull

Other sightings:
- 1 Grey Squirrel

 Additional bird species for my 2020 bird list at this site:
29      Herring Gull

A good angle to see all the features of a flying first-winter Herring Gull. Above the dark tail-band the upper-tail is spotted – on a Lesser Black-backed Gull the tail-band stands out black and clearly contrasting with a white upper-tail. The inner primaries are obviously paler than the rest of the wing trailing-edge.

This is, I assume, the same Yellow-legged Gull that has been present for some weeks – the dark smudges on the greater coverts suggest it is not quite a full adult. The sequence of photos that I took this morning sent me back to the literature. Note the bold white ‘mirror’ on the outer primary only.

Here as it is about to land we see the legs are ... not yellow! I might be persuaded that the legs are pale yellow and the feet are pink, but ...

... here I am less convinced.

A shot of the underside does not really help. It confirms that the ‘mirror’ is on the outer primary only. Any gull that is not fully adult would be expected to show some dark smudging in the tail – this does not. But if it is an immature then that might explain why the legs are pink and not yellow. Puzzled of Newport!
