Priorslee Lake and The Flash

6.0°C > 7.0°C: Clear skies. Light SW wind. Very good visibility.

Sunrise: 07:49 GMT

* = a photo from today.

After all the recent rain, especially yesterday's downpours, both pools are at about the highest level I can recall.

Priorslee Lake: 06:47 – 09:28

(241st visit of the year)

Bird notes:
- When the two adult Mute Swans swam away from the south-west grass only three of the four cygnets went with them. The other cygnet only joined them after about ten minutes.
- Three Pochard were new in. Unusually there were more ducks (two) than drakes (one).
- The Tufted Ducks were continually moving around and hard to census. At least 44: possibly as many as 53 (33 drakes).
- Unusually the Goosander stayed for a protracted period, still present when I departed.
- A Water Rail was heard calling from the north-west reed-area on four separate occasions.
- All the Fieldfare and Redwings were seen early flying over / out of the fields to the East.
- A group of 12 birds flew out of the West end area where the Reed Buntings roost. I am not at all sure what they were. They were Reed Bunting-sized though the flight was more direct than the jerky flight typical of Reed Bunting. They seemed rather too small to be Redwings though with the same rather slender body. I did not hear any calls. Finches?

Also noted:
Nothing else

Not an inspiring sunrise but I will take a dry morning anytime.

A duck Pochard. Even in eclipse (moult) plumage drakes do not show a pale eye-ring.

The rather unusually long-staying brownhead Goosander at the lake. Often this species leaves within minutes of arriving.

An individual Goldfinch from one of several small flocks noted.

Aircraft of the day. This is a Rockwell Commander 114B whose owner lives near Chippenham. Flight trackers do not provide complete detail of the flight but it appears it is en route from Kemble (near Cirencester and also known as Cotswold Airport) to somewhere near York. It returned later in the day. Only about 1500 examples of Commander 112 and 114 models were built in North America between 1972 and 2002 despite its appearance being rather more stylish than the ubiquitous Piper Cherokee and Cessna ranges. This example dates from 1999. The "G-E..." registration hints at a simple one character repaint from its previous ownership in Germany where the "D-E..." range "ist obligatorisch" for all single-engined light aircraft.

The Flash: 09:31 – 10:25

(234th visit of the year)

Bird notes:
- Now all the geese appear to have gone. I cannot recall a 'no geese' day before: perhaps when the water has been completely frozen?
- Certainly four Great Crested Grebes.

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

Noted on / around the water
- no geese
- 2 + 4 (1 brood) Mute Swans

On / around the street lamp poles:
Nothing noted

Noted later around the Ivy bank:
Among many 100's of flies of various species
- 2 Common Wasp (Paravespula vulgaris)
- *1 Marmalade Hoverfly (Episyrphus balteatus)

A Marmalade Hoverfly (Episyrphus balteatus) attempting to extract some nectar from what looks rather like an Ivy flower that has seen better days. Despite its delicate appearance, provided the weather is mild and sunny and there are flowers available, then this hoverfly can be seen throughout the year.
