A frosty morning. A Common Gull trotted over frozen ground, too hard to allow it to dig for worms. It had migrated south to get away from things like this.

A mob of gulls flying past the island, almost all Black-Headed but can you spot two Common Gulls and two Herring Gulls?

A Lesser Black-Backed Gull plunged vertically into the lake ...

... submerging with its wings partly extended. I think they use their wings to steer under water, but don't think they can actually fly in water like Gannets.

The female Peregrine was on the tower in the morning. No sign of her mate.

A pair of Great Crested Grebes cruised up the Long Water.

I went to the Round Pond to check on the Black Swan. She seems to have calmed down after her recent troubles, and was swimming around placidly.

Mute Swans toiled to gain height to cross the bridge above the passing traffic. It would be much easier to fly under the arches, but they find that frightening.

Glad to say that the Goldeneye is still on the Serpentine, though I missed seeing it yesterday.

The Grey Heron in the Dell likes to stand on the weeping beech tree, but that exposes it to Carrion Crows, which hate herons and enjoy teasing them.

A Nuthatch called from a tree near Queen's Gate.

A compilation of Robins singing in different parts of the park.

A male Chaffinch ...

... and a male Great Tit came out to be fed in the shrubbery near the bridge.

I've been collecting short clips of people exercising in strange ways, and the third agonising procedure which I saw this morning made up a set.
