Noted on the West end street lamp poles pre-dawn:

Before the brief deluge it looked promising to the far East. The weather was coming from the West.

The best-looking male Mottled Umber moth Erranis defoliaria I have seen this year! Well all-winter actually.

A male plumed midge. A larger species than many seen recently. Still no specific identity though.

The best winter cranefly Trichocera sp. specimen this morning.

A two-fer. On the left a small unidentified springtail that I had not noticed until I processed the photo of the possible Cabbage-stem Flea Beetle Psylliodes chrysocephala on the right.

A millipede I have not been able to identify. There are 62 species in the UK and many are not illustrated on the internet. Another confusion is that in some species immatures look very different from adults. The number of legs is not the correct distinction between centipedes and millipedes though it usually works. The actual difference is that millipedes have two pairs of legs on each body segment while centipedes have only one pair.

Present for over a week this Long-jawed Orb-web Spider Tetragnatha sp. has moved several inches from where I saw it on Tuesday. So it is not dead.

Priorslee Avenue tunnel:

It is a while since I checked the tunnel. Now I know why. I saw nothing, zilch.

Significantly missing was Wren. Robin was unusually late in getting on the list.

No mistaking a drake Tufted Duck.

Nor Mrs. Angry Tufted Duck.

At this time of year it is easy to separate the sexes. Frustratingly during the Summer period when they are moulting and difficult to sex they never seem this approachable for close study.

This Grey Heron is an upstanding member of the community.

Is it cross-eyed? The bill looks brown here.

This view shows that the lower mandible is orange toned.

A Song Thrush of course. I noted one singing and two others searching the ground for morsels.

First flower of the year (and last of 2025). One of a cluster of White Dead-Nettles Lamium album that seems to flower throughout the year.
