There is no sign of them nesting under the little bridge in the Dell, but it's still early and at least they are hanging around the area.
A Greenfinch was singing at the top of a tree on the west side of the Long Water.
They like high places to sing from, unlike Blackcaps which tend to stay in the shelter of bushes. But at last I managed to get a photograph of a male Blackcap today, as he paused on his way from one invisible singing station to another.
The Coot in the nest in the boathouse was turning over her eggs.
I haven't seen a sign of the people who operate the racing skiffs on the lake, so it looks as if she will be allowed to raise her brood undisturbed by humans -- and, just as importantly, by the numerous hungry Herring Gulls and Lesser Black-Backed Gulls that devour most of the young water birds on the lake.
The male Tawny Owl was in his usual place, though he was sitting rather low and I could only see his head and shoulders.
It is now completely impossible to see him from the front when he is sitting here; he is completely obscured by leaves. When the owlets emerge (and I still think there really are owlets) we are going to have a hard time seeing them.
The carrot cake served at the Lido restaurant is widely renowned.
Update: Mario has identified yesterday's mystery fungus as Poplar Fieldcap, Agrocybe cylindracea, a good edible species.
