Parts of the Long Water and the Round Pond were covered with ice. Some birds were having difficulty: this Coot could hardly walk and kept falling over.
A Mallard drake was also having difficulty keeping his balance.
The Shovellers were revolving serenely. They don't need a very large area of water for the shovelling and filtering that supply their food.
A Great Crested Grebe was at the edge of the ice next to the bridge, diving and fishing under the ice sheet. They are well aware that fish like sheltering under things, an insufficient protection when there is a hungry bird rushing around with great speed.
The Blackbirds are noticeably hungrier when the ground is frozen, and some quite shy birds allowed me to feed them. But the cold didn't stop a Blackbird from bathing in one of the little pools below the Rima relief ...
... and when it had finished, a Great Tit bathed in the same place.
The Jackdaws at the Round Pond seemed to be finding enough to eat. Being bigger and stronger than Blackbirds, they probably have less trouble extracting worms from the hard soil.
The male Tawny Owl was dozing peacefully in his usual place in the horse chestnut tree. Several photographers had come to admire him, but he is used to that and takes no notice.
