A splendid sunrise, my best of the year here so far. Starting early.

Spreading across the width of the eastern horizon.

Then out across the sky.

A different perspective.

This small group of Tufted Duck took off, flew around briefly and then left high to the north-west. Certainly four drakes with the bird at the front of the lower group looking to be a duck.

There might not be many Coots here this year but that doesn't mean it is all sweetness and light.

My first sighting of today's Common Sandpiper flying on typically bowed wings, not raised above the horizontal.

I managed to find where it had settled on the dam-face.

I think I have been seen! The white on the belly extends up toward the shoulder and is diagnostic of this species (apart from the equivalent New World species, Spotted Sandpiper. which is a vary rare vagrant to the UK and, in Summer, can be identified by having black spotting on the belly)

The Great (White) Egret did not stay this morning, flying off..

 ...noisily...

...as it did so. The legs on this species stick out more than they do on...

...Grey Heron. Was everyone leaving?

The many Sand Martins mainly stayed high in the sky. The few (two?) Barn Swallows, as here, stayed low over the water.

Today's unidentified fly though I think I saw this species yesterday.

This may be a male Missing Sector Orb-web Spider Zygiella x-notata. The cephalothorax marking of a wide dark band on an otherwise brown area is a good match. Its other common name of Silver-sided Sector Spider does not seen apposite here. So?

In the Priorslee Avenue tunnel:

Flies
- *4 unidentified midges
- *1 moth fly Psychodidae sp. [Drain Fly or Owl Fly]

At least three of the midges on the wall of the tunnel today must have been different to any seen yesterday as they were this smaller, more compact species not previously noted here.

And a moth fly Psychodidae sp. today
