The male Tawny Owl reappeared in the horse chestnut tree next to his nest tree, only to disappear again when harassed by Jays.

The male Little Owl came out several times during the afternoon to sunbathe.

There are three Starling nests in one of the plane trees next to the small boathouses, and I think two in the other. Only one is clearly visible from the ground. No matter how often the parents feed their ravenous youngsters, they never stop crying for more.

A Blackbird near the leaf yard was gathering worms for his own nestlings.

A dozen House Martins were flying around the embassies. I could clearly see three plaster roses on the cornice that had nests on them, but there are probably more. Quite likely some chicks have already hatched, as the adults were constantly flying to and from their nests. Here a bird squeezes into the nest space.

There were some very large carp under the parapet of the Italian Garden. Here a Great Crested Grebe looks at one that is definitely too big for her.

The three Mallard ducklings near the bridge have survived so far. As they grow larger they are in less danger from the Herring Gulls, of which there were at least a hundred on the lake today.

Some oaf had thrown a deckchair into the Serpentine. It was an attractive shade of green, so an Egyptian Goose came over to see if it was edible.
