A clear morning. Frosty!

I mentioned yesterday that Great Crested Grebes were depleting the stock of Perch Perca fluviatilis. Here we go again.

The fish is sideways in the grebe's mouth here. It needs to be manoeuvred to that it can be swallowed head first to avoid the spines along the back of the fish.

 Difficult to do without hands.

 Part way there.

That's it. Now to swallow it...

It is a large fish, old-enough to have dark banding.

 Will it really fit?

 It doesn't seem so sure.

 That's it. Straight down.

Just the tail to go.

A Common Sandpiper in flight. It is not often you get to appreciate the under-wing pattern as it flies low over the water on flickering wings.

 "I can see you". The brown cap of a female Blackcap.

Making the harsh 'chack' alarm and contact call.

This male singing away shows why the species is called a Whitethroat. The Merlin app calls this species Greater Whitethroat which seems not unreasonable as there is a Lesser Whitethroat. However it is usually known as Common Whitethroat or often just Whitethroat.

This hoverfly was definitely my find of the morning. My first ever Gold-spotted Meligramma Meligramma euchromum aka Gold-spotted Smoothtail. I was puzzled by the Gold-spotted Smoothtail name given to it by Obsidentify: the scientific name Obsidentify provided did not match any of my reference books or anything on Steven Falk's web site. It turns this species was reassigned from the genus Epistrophella and as the new genus name of Meligramma is a different sex then the second part of the scientific binomial had to be changed from euchroma to euchromum. Which is why I had trouble finding any reference. It is an uncommon species with a southerly distribution.

A somewhat better photo of a fly on the 'boxing ring'. This seems to be a non-biting midge and not one of the possible 'dance flies' I photographed here yesterday.

The Ramsons Allium ursinum flowers are now fully open.

An illustration of why mining bees are extra hard. This is a male Orange-tailed Mining Bee Andrena haemorrhoa.

This is the larger and more colourful female of the species. At least she has the decency to show her orange tail.

A delightfully scruffy-looking Common Carder Bee Bombus pascuorum.

Between the Balancing Lake and The Flash:

Moths:
- *1 Flame Carpet

Next to the street lamp that seems to attract moths I found this individual on the academy railings. It is a rather pale and rather early example of the first generation of a Flame Carpet Xanthorhoe designata.

The Flash: 06:20 – 07:15

(88th visit of the year)

New Bird Species
Best here was a *Common Sandpiper. A bird I see here most, but not all years, either on Spring or Autumn passage. My #60th bird species here this year.

Other bird notes:

Bird(s) noted flying over here:

None

Warblers noted (the figure in brackets relates to birds heard singing):
- 3 (3) Willow Warblers
- 8 (8) Chiffchaffs
- 11 (8) Blackcaps
'nominal' warbler:
- 3 (3) Goldcrests

Noted on / around the water:
- 25 Canada Geese: of these a pair flew off
- 3 Greylag Geese: of these a pair flew off
- 2 + 4 Mute Swans
- 10 (9♂) Mallard
- 16 (11♂) Tufted Duck
- 6 Moorhens

- no Great Crested Grebe
- *1 Common Sandpiper

- *1 Lesser Black-backed Gull: second year

Noted elsewhere around The Flash:

Beetles:
- 1 Alder Leaf Beetle Agelastica alni on street lamp poles

At best a record shot of a Common Sandpiper. A Starling-sized bird across the width of the water is not easy to photograph.

Two adult Herring Gulls were here again.

A second year Lesser Black-backed Gull sitting on a roof in Derwent Drive. Only full adults have the yellow legs.

In this view you could not tell what colour its legs are.
