The Reed Warblers have arrived from Africa. A male was singing in the reed bed below the Diana fountain.
Otherwise it was just the usual small birds. Blackcaps -- also migrants, from southern Europe -- were singing around the Long Water. This one was at Peter Pan.
So was this Wren.
A Chaffinch perched on a twig, holding a small larva. Evidently there's a nest here.
There certainly is a Long-Tailed Tits' nest in the brambles between the bridge and the Vista, as I've seen the parents carrying insects. One perched on the variegated holly tree that seems to be a good hunting ground.
The nest in the Rose Garden can actually be seen. A parent perched on a nearby azalea.
A Robin came out on the railings of the Dell ...
... and another lurked in a red-leafed hazel bush in the Flower Walk.
A Pied Wagtail perched on a corner of the Dell restaurant roof.
The Grey Heron on the stairs at the bridge eyed a couple on the bench, hoping they'd produce a bit of food.
I filmed this literally from my front doorstep looking across the street, where a Herring Gull on a cornice was being harassed by a Carrion Crow. There is a square with trees just down the road and maybe crows are nesting there and the nest needs to be defended, but maybe it's just that the crow wanted a bit of fun.
A Herring Gull stared down at Coot nesting against a post at Peter Pan, wondering if there were any chicks it could grab. There aren't yet.
An Egyptian gosling on the Serpentine scooted around picking insects from the surface. They need the extra protein in order to grow.
The Greylag Geese brought their three goslings ashore to graze, a perilous undertaking as any moment a dog might appear and the family would have to flee to the water. The other two geese were tolerated as long as they didn't come too close, and indeed two more pairs of eyes would be helpful in watching for danger.
The single gosling was just along the bank.
The five Mallard ducklings are growing fast and perhaps already out of danger of being snatched by a Herring Gull -- but there are plenty of other hazards for a young bird.
A male Green-Veined White butterfly posed obligingly behind the railings at the Vista. The green(-ish) veins are only visible on the underside of the wings.
