A Whitethroat sang on a tree in the Rose Garden. There seem to be more than usual of these birds at the moment -- they are not common in central London.

A Blackbird was in good voice in a tree nearby.

An adult Long-Tailed Tit and a young one perched side by side in a hawthorn tree.

At the bridge, an Adult Grey Wagtail was on one post ...

... and a young one on another, waiting to be fed. But the adult seemed to think it had had enough for the time being, so I didn't get an action shot.

Two young Grey Herons faced each other across the little stream in the Dell.

Then one of them went down to gaze longingly at carp far too large for it to eat.

A pair of Moorhens chased each other. One gave a wide berth to the heron -- they have been known to try to eat Moorhens -- and the other preened.

Both the Coots that were evicted from their nests by herons had bounced back. One of them celebrated by decorating the nest with a red plastic toy boomerang.

One of the Coot nests foolishly sited on the edge of the Serpentine has been abandoned, and a Greylag Goose was going through the twigs looking for insects.

A pair of Mute Swans nesting on the Serpentine island have three new cygnets.

The pair on the Long Water were back on their little island, and only one of the cygnets was visible.

The three Mallard ducklings on the Long Water are already able to catch flying midges.

There was a female Mandarin at the Vista, the first seen for a while. Evidently a nesting attempt has failed.

Mandarins fare poorly in the park, but there is a thriving colony not far away on the Regent's Canal.

I think this is a female Common Blue Damselfly. It was near the Serpentine Gallery.

But I have no idea what this is -- I don't even know if it's animal or vegetable. There were several of them in the moth-spun webs on the bush near the Triangle car park.

There are some particularly vivid purple irises in the Rose Garden.
