(152nd visit of the year)

Bird Notes

New Bird Species
Highlight today was a Green Woodpecker calling from the north-east area at c.07:50. While I was still approaching the bird was seen to fly off across Castle Farm Way and then heard calling far to the East. Until 2020 I noted this species regularly in the area. It bred along the North side in the mid-late 2010s. My previous record was of a bird heard distantly on 9 April 2021. It is my 98th bird species here this year

Other bird notes:
- another pair of Mute Swans was present throughout. There were occasional skirmishes but provided the interlopers kept to the West end everyone seemed content.
- neither duck Mallard with ducklings was seen.
- 51 Black-headed Gulls (one juveniles) but no large gulls were on the football field c.06:00. Something spooked them and many took refuge on the roof of the academy. The question arises as to where they go when they leave here as only a handful visit the lake.
- I did not see any Great Crested Grebe with any juveniles.
- a trio of Swifts was over the North wood as I arrived. Two were to the East after the breeze picked up.
- a Grey Wagtail on the dam-face was my first post-breeding record of this species.

I seem to be making a habit of this: as good as it got taken soon after dawn.

This is what I have been doing most of the day. Watching aircraft at a local private club fly-in. The weather was no better.

All the Black-headed Gulls on the football field c.06:00 took off with many of them perching on the roof of the academy.

Early in the season there were three Chaffinches singing and holding territory. The only singing bird is now at the East end. I photographed this one at the West end. This is a female: note the grey collar.

 A Small Fan-footed Wave moth Idaea biselata on one of the street lamp poles. So far this year I am well down in both the number of moth species and the number of individuals recorded.

Not sure about this small fly with red eyes, metallic-looking thorax and swelling on the hind legs. These features match the soldier fly Beris geniculata but as usual there are similar species.

 I cannot identify this fly. I was attracted(?) by its very hairy abdomen. The poor light meant there was not enough depth of field to get the whole creature in focus.

Another unusual fly with a striped thorax and tapering body. Obsidentify suggested a Fannia species. Neither of the two species in this genus illustrated in the NatureSpot web site match.

A Common Red Soldier Beetle Rhagonycha fulva on a grass head. Look closely and there are two other creatures visible. One under the tip of its left antennae. And the other between its two left front legs. No idea what they mite(?) be!?

 Also on a street lamp pole was this Cucumber Green Orb Spider Araniella sp. either A. cucurbitina or A. opisthographa.

A better view of a female Leiobunum rotundum showing the diagnostic parallel-sided dark saddle extending the length of the abdomen.

The Flash: 06:15 – 07:05

(155th visit of the year)

Bird notes:
- many of the Canada Geese initially seemed to be missing: they were not in the water. I found these later on the grass along the East side. Why? Is the food in the water now running out? Are they sufficiently confident about their re-growing flight feathers and believe they could scramble to the water if a threatening dog were to appear? Or is it simply herd instinct after one bird decided the grass was greener?
- at least one Coot still sitting and what I believe to be its mate seemed to be constructing a new nest nearby.
- no sight or sound of yesterday's Reed Warbler.
