On / around the street lamp poles pre-dawn
Nothing noted. Too windy?

Later:
Nothing of note

At last a mostly clear sky at dawn with a half-decent sunrise.

We had better have another view in case it doesn't happen again!

 And another.

The clouds had the decency to stay to the West for a change.

It seems to be a glutton for punishment. The stray Mute Swan cygnet was back again – for a while.

 Nearly dipping a wing-tip as it hastens away.

Record shot: the unmistakable silhouette of a Little Grebe. I saw it before it saw me – just. It dived and was not seen again.

A male Bullfinch eating buds: as they do. Does not seem to have much effect on the amount of Blackthorn and Hawthorn blossom that develops.

The Flash: 09:25 – 10:45

(24th visit of the year)

Bird notes:
- What was presumably the same Mute Swan cygnet seen recently, including today, at the Balancing Lake, was being chased around by the resident adults (and also the remaining resident cygnet some of the time).
- The Water Rail was glimpsed again. I was ready with the camera but it saw me first and dived in to cover. All I could see where it had apparently gone was a Brown Rat.
- Strangely I heard no Song Thrushes today. There were nine singing at the Balancing Lake so why were they quiet here?

Birds noted flying over here:
- 1 Sparrowhawk
- 18 Jackdaws
- c.25 Redwings to the North put up from trees by the Sparrowhawk

Noted on / around the water
- 76 Canada Geese
- 1 Canada x Greylag Goose
- 14 Greylag Geese
- *2 + 2 Mute Swans: see notes
- 45 (25♂) Mallard
- 1 all-white duck (Peking(?) Duck)
- *3 (3♂) Pochard
- *50 (24♂) Tufted Duck
- 3 (0♂) Goosander
- 1 Water Rail again
- 11 Moorhens only
- 69 Coots
- 1 Great Crested Grebe
- *116 Black-headed Gulls
- 1 Herring Gull: immature
- 1 Lesser Black-backed Gull: adult
- 1 Cormorant
- *2 Grey Herons

On / around the street lamp poles:
Nothing noted

Of note elsewhere:
- 1 Brown Rat (Rattus norvegicus)

What seemed to be the same stray Mute Swan cygnet was here later. Almost too close.

Coming in to...

 ...splash-down.

The resident cob was not happy. Here he is powering along. I don't really understand why he didn't just fly straight at the cygnet to drive it off. It would seem to take less energy than ploughing through the water.

Back to three drake Pochard this morning, all asleep here with a duck Tufted Duck asleep in front of them. Some bird books say that Pochard are nocturnal feeders and spend daytime asleep. This is not entirely true: the two yesterday were diving for vegetation in daytime.

 I think this Black-headed Gull has been watching too many Gannets fishing.

"Go on, son".

"Right under".

Oh: it didn't drown.

A Grey Heron disguised as a flying barn door.

The light was slightly better on the male Bullfinch eating buds here. Still too many branches in the way. This is normally a rather shy species. He was sitting in a tree above the academy's pre-school play area and seemed unfazed by the noise and activity.

Plane of the day: it is a Diamond Aircraft DA 40-TDI Diamond Star owned by Twinstar4Hire Ltd. of Beaconsfield. The logo on the tail is of "Leading Edge Aviation" who offer commercial pilot training out of London Oxford Airport at Kidlington. The aircraft, designed and built in Austria, is a two-seat basic trainer used on the initial stages of the courses.
