A bitterly cold night froze the Long Water again in spite of the keen wind. A Coot ...

... a Moorhen...

The air bubblers had made holes in the ice where Black-Headed Gulls were feeding.

In spite of the this some Great Crested Grebes, which had fled to the river when the first frost set in, had returned, sensing the end of the cold weather. They shrug off cold but are afraid of being trapped by ice, because their very long takeoff run would prevent them from flying out.

The Black Swan was in a bad mood, and chased a large male Mute Swan across the Serpentine,

The pigeon-eating Lesser Black-Backed Gull had struck again, and a young Lesser Black-Back was finishing off the remains of his victim.
