There had been a hard frost last night, and both lakes and the Round Pond had ice on them. This Mallard was at Peter Pan, where there was no clear water.
However, there was an unfrozen area on the far side of the Long Water, and the whole family of Mute Swans came down it to see what was going on around their nest area -- the workmen have still not returned. The swans can't get to their new island at the moment because it is surrounded by ice.
The people from Bluebird boats had started up the electric boat and were circling on the Serpentine to clear an area of ice. However, this Coot and Tufted Duck had their own icebreaker, a large male swan which they were following closely.
The Round Pond was three-quarters frozen, and the Scaup had left. It may be elsewhere in the park, but I couldn't find it.
The Great Crested Grebes are always wary of being iced in and leave for the river if there is a danger of it. However, they were all still here today -- six on the Long Water, two on the Serpentine -- and perhaps they sense that the weather will warm a little during the next few days. This one had been fishing under the ice near the Serpentine island, and was having a preen and a flap.
The three Canada-Greylag hybrid geese, not seen for a while, were back on the Serpentine. They always keep together and are certainly siblings, although they don't look much alike. The one on the left has an intensely speckled head and a speckled body. The middle one has a pattern quite like its Canada father. And the one on the right is intermediate.
Charlie and Melissa the Carrion Crows followed me all the way from the Round Pond to Rima, demanding peanuts. This is Melissa on the fence in front of Rima. Her feet are paler than Charlie's.
The male Tawny Owl was in his usual place enjoying the sunshine after a freezing night.
Here is a picture of a Robin in the leaf yard, for no reason except that Robins are beautiful.
