Priorslee Balancing Lake and The Flash

2.0°C > 3.0°C: Low/medium overcast. Light / moderate southerly wind. Moderate / good visibility.

Sunrise: 08:11 GMT

* = a species photographed today

Priorslee Balancing Lake: 06:35 – 09:30

(16th visit of the year)

Small amount of thin ice remaining.

Bird notes:
- no drake Pochard seen: instead both the birds noted were ducks.
- no gulls were present until the first of c.400 Black-headed Gulls started arriving at 07:30. It was almost ten minutes before the first of c.325 large gulls started arriving. All the gulls arrived in steady streams rather than the large groups of yesterday. Most had gone by 08:45 and there was no later arrival before I departed.
- a second Grey Heron present for at least some of the time. They seemed, unusually, to be getting on together.

I have been struggling to identify this species that I have seen many times for many weeks. The clear wings were a puzzle and the most common of the winter craneflies Trichocera regelationis has a wing spot which this lacks. Thanks to Google Lens for the suggestion and NatureSpot for more information I now believe it is most likely T. annulata.

My apps seem as confused as I am over the spiders I show to them. This spider was on the identity label of a street lamp pole pre-dawn.

This spider on a wall of the Telford Sailing Club HQ seems to be one of the Neriene species. The size of the palps indicate this is a male.

Another spider on a wall of the Telford Sailing Club HQ is this very plain-looking Long-jawed Orb-web Spider Tetragnatha sp. And no: it does not have an ovipositor – that it the shadow of a leg!

This is rather sad. There has been a drake Tufted Duck here with a growth on its neck since early last year (though it was missing during the Summer). The growth is now very large and the bird was sitting quietly under overhanging vegetation. I surmise it is not well. The positive is that whatever has caused the growth does not seem to have affected any of the other Tufted Ducks, or indeed and other birds.

A first-winter Herring Gull. The typical adult-colour is beginning to appear at the front of the back and also shows at the base of the patterned feathers on the folded wing.

Just three of the many Lesser Black-backed Gulls here. These are all adults.

A Long-tailed Tit trying hide behind twigs.

Well that's not very nice.
