A Great Tit sang in a bush. This is the classic two-note song described in books, but in fact Great Tit songs can have anything from one to eleven notes, and vary a lot. If you hear a song you can't identify, it's probably a Great Tit.

The Coal Tit near the bridge came out to be fed.

The Long-Tailed Tits in the Rose Garden were busy building their nest in the gorse, often pausing in a thorny bush on their way to collect materials.

The gorse is even spikier, but that doesn't worry them. The bird is standing on the partly completed nest, but I couldn't get a sight of this without disturbing them.

A Blackbird came out from under the gorse.

A Wren sang on an adjacent bush ...

... and a Robin hopped around on the ground.

Another Robin on a bench in the Flower Walk picked up what looked like crumbs from someone's lunch.

The Goldcrest in the leaf yard was dashing about in the yew tree.

A Redwing in the enclosure east of the bandstand forgot it was being watched and came quite close to the camera.

The Mute Swans on the island, frustrated on not being able to get through the gate, took it out on a Canada Goose that was minding its own business.

A little fleet of Tufted Ducks cruised around the east end of the Serpentine.

One of the dark Mallard drakes dozed under the willow tree next to the bridge.
