A Grey Heron looked across the Vista at five others, which had assembled on the gravel bank too close for comfort.

Inevitably conflict broke out.

Another heron perched on the Henry Moore sculpture was caught by a tailwind that ruffled its feathers. It hastily turned round.

A wide-angle shot of the Coots' nest resting on the lake floor shows the size of the waterlogged branches that the birds have somehow managed to drag and assemble. I simply don't see how they did it.

Strong and aggressive as Coots are, they are no match for agile and sharp-beaked Great Crested Grebes at close quarters. So the grebes at the island are still in possession of their stolen Coot nest -- as long as there is always one grebe on it.

The Mute Swans nesting at the end of the Lido restaurant terrace seem to have settled in. But it's extremely unlikely that they will get away with nesting in this exposed place, behind a low fence that even a lazy fox could easily jump over.

The Canada--Greylag Goose hybrids on the Serpentine are not the best looking of geese, but this one with a speckled head is quite attractive.

Just one Little Owl was visible today, the female near the Albert Memorial.

Johanna van de Woestijne edits the longer video clips on my YouTube channel, such as the one about the pigeon-eating Lesser Black-Backed Gull, which has now had about 115,000 views. She is visiting London, and took the opportunity to feed the tits at the leaf yard, including the shy Coal Tit which is a very difficult bird to attract.

Tom made this remarkable slow-motion video yesterday of a Nuthatch coming to his hand.

A Goldcrest was bouncing around in the Dell.

As I walked home, I passed through a flock of Goldfinches in the street.

The Song Thrush near the bridge is now in full and glorious song.

A pretty pink-flowered currant bush at the Vista attracts a lot of bees.

I have always been puzzled by these stones set into the tarmac at the edge of the Round Pond, which seem to mean 'No bullfighting'.
