A Grey Wagtail on one of the rafts at the east end of the Serpentine reached casually into the leaves and turned round with an insect in its beak.

A Wren was scolding noisily and hopping around in a tree near the bridge.

Carrion Crows use this rattling call as a signal to mob a predator such as a hawk. But I couldn't see a predator overhead, and no other crow seemed to respond to the call.

The remaining fruit on the rowan trees on Buck Hill attracted several Blackbirds ...

A Great Crested Grebe flew down the Serpentine.
