New Bird Species
Yet another two additions to my 2024 bird list from here:
- there were three Blackcaps singing as I made my first circuit of the lake c.06:00. Strangely none was heard later. [my first in 2023 was on 26 March]
- two Sand Martins were briefly over the water at 07:10. Another was noted flying West at 07:45. Also rather unusual behaviour in that migrants usually stop off to hunt insects low over the water. [the same date as my first in 2023]
These birds bring my 2024 species count here to #72.
Also a mystery. As I walked across the Wesley Brook bridge at c.05:35 there was a loud splash and waves in the brook. Clearly something large had entered the water. But what? I saw nothing to help solve the mystery. An Otter?
Other bird notes:
- the pair of Gadwall was a welcome sight: they have been scarce this winter here. Just perhaps the birds from The Flash that were not seen today.
- *three Great Spotted Woodpeckers were noted in the Ricoh copse area. A calling bird flew to perch in a tree-top while two others circled around chasing. I could not see the nape colour on the perched bird: perhaps a female with two suitors?
- no fewer than 12 Blackbirds heard in song: the first day I have noted more singing Blackbirds than singing Song Thrushes (nine of those today).
- I noted a Greenfinch doing its bat-like territorial flight for the first time this year. As well as the rasping 'song'.
- Just two Siskins noted.

There was not a good sunrise. This was taken later after some light drizzle when the cloud had begun to break.
A Great Spotted Woodpecker in the top of a tree in the Ricoh copse...
...while, would you believe, these two circled around and around.
Quick: photo Chiffchaffs before they can hide behind leaves.
Same bird: different pose.
One of my worst-ever moth photos as this individual ran around and around the street lamp pole eluding me much of the time. Luckily the white spots on the wing are sufficient to identify this as a Common Brindled Brown Agonopterix heracliana. The vernacular name is that shown on the Midlands Moths web site: previously it was known as Common Flat-body.
This midge Psectrotanypus varius was on the wall of the Priorslee Avenue tunnel. I cannot recall seeing this species previously.
One of two Common Shiny Woodlouse Oniscus asellus I noted on the street lamp poles.
And here is the other. There was one more on the wall of the Priorslee Avenue tunnel.
I noted this White-legged Snake Millipede Tachypodoiulus niger on the street lamp poles. Again there was another on the wall of the Priorslee Avenue tunnel.

Arthropods:

Spider:
- *1 crab spider Philodromus dispar
- *1 crab spider Philodromus dispar
I found this spider on the wall of the Priorslee Avenue tunnel. The pale markings around the edges of the metathorax and the abdomen identify it as the crab spider Philodromus dispar.

Bird notes:
- only the cob adult Mute Swan was noted. Try as I might I could not find the pen in any of the likely nesting areas. I am sure she was still around, probably always the other side of the island.
- Gadwall not seen. Perhaps the pair that flew off from the Balancing Lake earlier.
- two Great Crested Grebes now. They seemed disinterested in each other.

Great Spotted Woodpecker was not just at the lake this morning. Of course it was almost at the very top of the highest trees.
A female Blackbird during one of the brief sunny spells. Blackbirds can often be seen drooping their wings and exposing their rumps to the sun.
Resting on the Ivy bank I found this Red-tailed Bumblebee Bombus lapidarius. At this date it is almost certainly a queen as the workers are generally not on the wing until May.
There are two probable Lace-weaver Spiders Amaurobius similis just about visible here unless it is one pushing prey behind the crack in the street lamp pole.
