Priorslee Lake and The Flash

4.0°C > 5.0°C: A sliver of early red sky to the East; otherwise increasing low cloud and rain after 09:30. Light ESE breeze increasing moderate. Good visibility.

Sunrise: 07:42 GMT

* = a photo from today.

A quick canter around ahead (just) of the forecast rain in very dull conditions.

Priorslee Lake: 06:54 – 08:59

(238th visit of the year)

Generally a quiet morning, probably weather-related.

Bird notes:
- No sign of yesterday's pair of Eurasian Wigeon. However a duck Common Teal was flushed.
- A smart adult Yellow-legged Gull was one of rather few gulls seen.
- The low count of Jackdaws and Rooks might have been because I arrived slightly too late.
- Three Song Thrushes were singing away for part of the time.

Birds noted flying over here:
- 19 Wood Pigeons
- 2 Black-headed Gulls
- 2 Herring Gulls
- 14 Lesser Black-backed Gulls
- 4 Cormorants: together
- 11 Jackdaws
- 1 Rook
- 10 Pied Wagtails
- 2 Siskins

Warblers noted:
- 1 Cetti's Warbler: one brief call heard

Birds noted leaving roosts around the lake:
- None: at least three Reed Buntings calling from their roost area but none was seen to leave

Counts from the lake area:
- 2 + 4 (1 brood) Mute Swans
- 5 (3♂) Gadwall
- 8 (5♂) Mallard
- 1 (0♂) Common Teal
- 49 (>19♂) Tufted Duck
- 14 Moorhens
- Coots not counted
- 3 Great Crested Grebes
- 42 Black-headed Gulls only
- 2 Herring Gulls
- 1 Yellow-legged Gull
- 7 Lesser Black-backed Gulls
- 29 unidentified large gulls: pre-dawn
- 2 Cormorants: arrived separately; one departed

Noted on / around the street lamp poles pre-dawn:
- *1 plumed midge sp.
- *1 stretch spider Tetragnatha sp.
- *1 male Leiobunum rotundum/blackwalli harvestman

Later:
Nothing noted

Not much to show on a morning with very poor light. These all taken with flash on street lamp poles pre-dawn. This is one of the many 'plumed midges'. It is smaller and lacks the banded abdomen of the very common Chironomus plumosus. The other common and easy to identify midge is Microtendipes pedellus but that has pale green on the upper abdomen and pale legs. So this remains unidentified.

The unmistakable shape of a stretch spider Tetragnatha sp.

Male Leiobunum rotundum and L. blackwalli harvestmen can be hard to separate without close views. L. blackwalli has white rings around the eyes which this appears to have. However I think this might be reflection from the camera flash so I am keeping the log as Leiobunum rotundum/blackwalli-type.

The Flash: 09:02 – 09:40

(231st visit of the year)

Bird notes:
- The Goosander totals, at least, are likely to be an under-recording. Birds were moving around rapidly and diving for long periods.

Birds noted flying over here:
- 1 Lesser Black-backed Gull

Noted on / around the water
- 110 Canada Geese: 105 of these arrived in a single group with...

- 1 Grey Heron

On / around the street lamp poles:
Nothing noted

Later around the Ivy bank:
Nothing noted

A photo I took at The Flash yesterday. The body of this drone fly does look rather tapered though as it seems to have dark front legs it has to be a Common Drone Fly (Eristalis tenax).
