New Bird Species
An additions to this year's bird log from here:
- A Little Egret flew low East at 08:10.
This takes my 2023 bird species total for here to 68.

Other bird notes:
- The resident pair of Mute Swans managed to put two of the cygnets to flight. They soon returned.
- Two Collared Doves flew straight over as normal and did not, like yesterday, stop off.
- A Little Grebe flushed in to cover c.07:00 and not seen again.
- Just three pairs of Great Crested Grebes located. None of these seen displaying.
- Yesterday all c.130 Black-headed Gulls arrived together c.07:15. Today at least 75 were already circling over the water by 06:55 with at least another 150 arriving in a group c.07:05. Several small groups followed these.

Later:
Nothing of note


Early sunrise did not look too promising.

It did later colour up well.

A different and later view as the colour faded.

Another view.

Unusual behaviour from the resident Mute Swans, standing on the stones of the dam. The cob normally only comes out of the water here to chase the Canada Geese.

A drake Gadwall of course. Only three pairs noted this morning.

This Little Egret was overhead before I noticed it and I could only get a 'grab shot' as it headed away. What a long, slim bill from this angle. The yellow feet are just about discernible.

No visible means of support. A Jay passes over.


A Song Thrush with a modesty leaf!

This one won't find any snails up there.

Not so many Siskins this morning. The light was not good either. A female.

Two males here.

A male Dotted Border moth (Agriopis marginaria): females have very vestigial wings and cannot fly.

Nothing noted

Two Canada Geese and one Greylag Goose coming in to the food.

The Greylag Goose in close-up.

Now a Canada Goose in close-up.

 Feet down and wings spread.

A rather strangely pale duck Mallard. There was one present for a number of years but I cannot recall having seen it for many months (years?). Where has this one come from I wonder.

A Collared Dove rather unusually rooting about on the ground.

A first winter Black-headed Gull shows its wing pattern. The brown feathering along the leading part of the inner wing is beginning to be moulted out by new grey feathers.

This first winter still has well-defined brown markings on the wings.

The same bird

While on this first winter the brown markings are faded.

This adult shows the largest amount of dark on the head of any of the 50+ birds present. It is standing angled-on to me so the rear is rather foreshortened. Note the different leg and bill colour on this adult and the earlier first winter birds. These gull photos were all taken using my car as a hide to get closer.

You WILL learn to like gulls! This is a first year Herring Gull showing the upper-wing pattern...

 ...and the surprisingly intricate under-wing markings.

This adult Lesser Black-backed Gull still has much winter head-streaking remaining.

An immature Cormorant arrives. Surprisingly despite their large and rather threatening size none of the other birds seem to be concerned by their flight.

Always some friendly Robins.

Where's the food?

A different friendly Robin.
