Priorslee Lake and The Flash

5.0°C > 7.0°C: Mainly cloudy and dull with very light drizzle. Against all expectations clear intervals 07:15 - 07:30 and again c.09:45. Light W wind. Good visibility.

Sunrise: 08:01 GMT

* = a photo today

Priorslee Lake: 06:22 – 09:32

(268th visit of the year)

Two frustrations this morning:
- An owl flew past me at 07:15 and disappeared in to / behind trees. Most likely a Tawny Owl but all I could positively eliminate were Little Owl (it was too large) and Barn Owl (it was not pale enough).
- At 07:40 parties of six and 26 geese flew WNW. Clearly too small and with wing-beats too fast for Canada Geese but what were they? Unusually they were not heard to call. I guess Greylag Geese but could they have been Pink-footed Geese? The photos I took are too poor to make out anything meaningful.

Other bird notes:
- Yesterday there were Black-headed Gulls on the water by 06:45. Today none before 07:30 and then rather fewer.
- The 11 Black-headed Gulls logged flying over were passing high S in with the small passage of Lesser Black-backed Gulls. They seemed to have nothing to do with birds that had been at the lake.
- The pre-dawn large gulls, as far as I could determine, consisted of 78 Lesser Black-backed Gulls, nine immature Herring Gulls, two first winter Yellow-legged Gulls and the semi-regular second-winter Caspian Gull. Strangely only two of the Lesser Black-backs seemed to be immatures whereas all the other gulls were.
- The Feral / Racing Pigeons were in a tight group headed NW as is usual with Racing Pigeons being flown. Would they be racing / training in December?
- A big mixed group of Jackdaws and Rooks flew high over c.07:40. I counted 198 Rooks and there were more Jackdaws, though how many more I would not like to say. I have used >200 in the totals below. Another much smaller mixed group later. Earlier the usual several large tight groups of just Jackdaws.
- A Redpoll heard in the Alders near the Teece Drive gate where I photographed the Siskins yesterday. Too dull for a repeat session.

Birds noted flying over / near here:
- 9 Greylag Geese: outbound together
- 9 Canada Geese: trio, single and quartet outbound; single inbound
- *32 unidentified geese: six and 26 high NW: see frustration!
- 5 Cormorants: trio and duo
- 1 Common Buzzard: presumed the same bird over three times
- 11 Black-headed Gulls
- 29 Lesser Black-backed Gulls
- 10 Feral / Racing Pigeons: together
- 11 Wood Pigeons only
- >425 Jackdaws
- 212 Rooks
- 1 Pied Wagtail

Birds seen / heard leaving roosts around the lake:
- 2 Starlings: together
- 3 Redwings
- 7 Reed Bunting: more heard calling from roost site after these departed.

Counts from the lake area:
- 2 + 5 Mute Swans
- 11 (7♂) Gadwall
- 12 (7♂) Mallard
- 4 (3♂) Pochard
- 58 (29♂) Tufted Duck
- 1 Grey Heron again
- 8 Great Crested Grebes
- 11 Moorhens
- 197 Coots
- >125 Black-headed Gulls
- 84 Lesser Black-backed Gulls: 78 pre-dawn; just six later
- 9 Herring Gulls: all immatures pre-dawn
- 2 Yellow-legged Gulls: first winters pre-dawn
- 1 Caspian Gull: second winter pre-dawn

On / around the street lights etc. pre-sunrise:
- 1 Winter Moth (Operophtera brumata)
- *1 Trichocera sp. winter cranefly
- *1 small black beetle sp., possible the flea beetle Crepidodera fulvicornis
- *1 or 2 Nursery Web Spiders (Pisaura mirabilis)
- *2 Tetragnatha stretch spiders sp.
- *2 small 'jumping spiders'
- 2 other spiders, apparently different species

Noted later:
- *Turkeytail fungus (Trametes versicolor)

I listened to the weather forecast: the moon I did not expect. But it was OK - it was drizzling within the hour.

The 26 unidentified geese flying over at 07:48 (according to the camera).

I tried zooming in. Not enough light really. I am sure they are either Greylag or Pink-footed Geese but I cannot decide which. It was most uncharacteristic of these birds not to call. Calls would have identified them immediately.

This tiny beetle may - note the word 'may' - be the flea beetle Crepidodera fulvicornis. All flea beetles show a swollen hind leg to allow them to jump when threatened. Seems I was not a threat. This species is particularly associated with willows and there are plenty around the area. My caution is that there are more than 4000 species of beetle in the UK and an alarming number are black and round. Few show the swollen femur though.

A trio to ID here: they would not all get in to focus. On the left is a Nursery Web Spider (Pisaura mirabilis). In the middle is probably one of the Trichocera sp. of winter craneflies. On the right a jumping spider. There were two of them and when they met one leapt several inches around the lamp pole sideways without falling off - quite a feat.

One of the unidentified spiders noted. I have seen this rather plain-looking species several times before.

This small spider alongside one character of the lamp pole identification number looks to be like a small Tetragnatha stretch spider.

Another small spider I found this morning with part of a 1p piece for scale. The long two pairs of front legs held quite close together recalls the Nursery Web Spider. Perhaps it is a spiderling of that species and has yet to develop markings on the abdomen.

In a gloomy corner I found this common bracket-type fungus called Turkeytail (Trametes versicolor). Either left over from Thanksgiving or ready for Christmas.

The Flash: 09:35 – 10:39

(250th visit of the year)

Bird notes:
- Tufted Ducks especially difficult to census as there was much flying about.
- The Goosanders have taken to hauling out inside the island and can be tricky to locate.
- Two Great Crested Grebes seen displaying. Any third bird not located.

Birds noted flying over / near The Flash:
- 2 Lesser Black-backed Gulls: adults singly
- 5 Jackdaws
- 1 Raven

Counts from the water:
- 3 + 7 (1 brood) Mute Swans
- 23 Canada Geese
- 31 (18♂) Mallard
- 1 (0♂) Pochard again
- 61 (29♂) Tufted Duck
- 3 (0♂) Goosanders again
- 2 Grey Herons still
- 2 Great Crested Grebes
- 10 Moorhens
- 35 Coots
- 41 Black-headed Gulls
- 1 Lesser Black-backed Gull: dead body still not sunk.
- *1 Herring Gull: third winter briefly

On various lamp poles
- 1 November Moth-type (Epirrita sp.)
- *1 Honey Bee (Apis mellifera) caught in spider's web
- *1 Birch Shieldbug (Elasmostethus interstinctus)

On / around the Ivy or of note elsewhere
Nothing

The third winter Herring Gull that dropped in briefly. Note the small amount of brown on some of the folded tertials and the lack of any red on the bill.

The markings on the abdomen are classic Honey Bee (Apis mellifera). The thorax seems a bit too hairy so I thought I ought to check. It is a Honey Bee - one trapped in a spider's web and I am not sure whether it is alive and therefore whether I can put this species on my meagre December insect list.

I found this Birch Shieldbug (Elasmostethus interstinctus) lurking in the fold of a lamp pole. This common species can be found as an adult throughout the year.
