A slightly hazy sunrise but it will do. Vapour-trails produced by early arrivals in to Europe from the US.

Who is this standing on tip-toe. A clue – the white shoulder.

Yes: another Common Sandpiper passing through. Been ‘steady’ passage this year with no big numbers – have seen double-figures some mornings in previous years.

Aren’t Long-tailed Tits sweet? Even sweeter today as .... 

Some juveniles with them. Quite a different head-pattern.

In close-up and looking rather pensive.

Even quizzical here. Perhaps it is trying to make out what I am – I might be the first human it has seen. Almost certainly the first with a camera.

And from the rear. Look at the red eye-ring and the size of the eye-lids. Why do they have these? 

They eye-lids look even more startling here.

This adult is giving me the scowl – “keep away from my children”! Just look at those delicate feathers.

A Common Whitethroat carrying food. Grey head and brown in the wing.

And facing the other way. It was managing to sing with its mouth full.

Here is Mister House Sparrow eating leaves in the SW copse. Not a house in sight.

When I photographed this I assumed the Red-and-Black Froghopper (Cercopis vulnerata) had emerged from the case on the left but that is not so. I think the left hand insect is a newly emerged Alder Fly (Sialis lutaria) still drying out.

Other notes from here
- once more the Mute Swans show no sign of nesting
- not sure whether the Canada Geese goslings have formed a crèche: last visit the same number of goslings was split between four adults: now just two adults seemed to be looking after them all
- just one Great Crested Grebe apparently back: could not see in to the nest site now the leaves are on the trees
