Priorslee Lake and The Flash

2.0°C > 4.5C: Several light showers; also with some clear spells. Moderate W wind. Very good visibility. Just frosted again in areas sheltered from the wind.

Sunrise: 07:51 GMT

Priorslee Lake: 06:30 – 09:25

(143rd visit of the year)

First the bad news: a Planning Notice has appeared indicating there is an application to built 409(!) houses on the old Celestica site to the N of the lake. This has been derelict for >10 years (apart from when it was used as access route for Holy Trinity Academy construction traffic). More news as and when.

Notes from today:
- Canada Geese heard outbound as I parked up in Teece Drive but too dark to see them, especially with the very bright LED street lights ruining my night-vision
- Gadwall number making their daily change
- so where were all the Mallard today: just a pair!
- 3 (1 drake) Goosanders circled low but then carried on W at 07:50
- >150 Golden Plover again to the E at 07:50, somewhat closer this morning
- the juvenile Great Crested Grebe was heard begging again today. The pair at the W end were seen mating today. No pre-amble with display – they don’t have plumes to show off at this time of year. Just straight on with action. Not sure I have ever seen this species copulate before
- Water Rails heard calling in the SW area (a new location for the S-side bird?); in the NW area; and then much later at the NE end. Later still one flushed from along the N side – perhaps the NW bird straying for food?
- c.65 Black-headed Gulls straggled in from the W but then mostly left and no more than 20 at any one time later
- just three parties of high-flying Wood Pigeons, all NNE
and
- 1 Scarce Umber moth on a lamp. New for the year
- 1 Nursery Web Spider (Pisaura mirabilis) also on a lamp

Interesting to see the progress of this shower passing to the E. Here it is pre-dawn (hand-held at tenth of a second!) showing curtains of precipitation – likely sleet in the cold this morning.

Six minutes later and much less precipitation.

Ten minutes later – all gone: the cloud and the precipitation.

The sunrise when it came.

This is part of the very distant party of Golden Plover to the far E of the lake. The pattern of the flocks in flight is quite distinctive. There is just about enough definition to enable us to see the long and pointed wings on this species.

This is a Scarce Umber. I thought it would be another specimen of the rather variable Mottled Umber but noted that there was no obvious ‘dot’ towards the edge of the forewing – just a smudge. Checking the web site here for the ‘flying tonight’ showed that the straight line just in the basal part of the wing meant it has to be a Scarce Umber. Like several of the recent winter moth sps. this individual was found rather low-down on the lamp posts which I do not recall before. Perhaps they find the new LED lights too bright? Perhaps they are just searching for the wingless females typically climb up trees (and lamps!). My first Scarce Umber for several years.
