The Black Swan, whom I missed yesterday, was at the jetty near the Diana fountain, and this time he had his girlfriend with him.
He was actually on the lake yesterday: Virginia Grey saw him. He must have been behind something when I passed.
The Polish Black-Headed Gull with ring code T4UN flew by.
I have seen it several times in the past few years, always in much the same place, on the north shore of the Serpentine west of the small boathouses. This is typical of Black-Headed Gulls, which migrate hundreds of miles but stick to the same spot when they arrive.
A Cormorant was fishing near the bridge. Here it is under water zooming over the wire basket of twigs, looking for a fish that had carelessly ventured out of shelter.
A group of Greylags flew down from the Parade Ground to the Serpentine.
There was a small fleet of Red Crested Pochards at the island.
Most of the ones on the lake are male. Possibly, as with Common Pochards, the sexes migrate separately. But the two species are not closely related; they just happen to look rather alike.
A red carrier bag was blown by the wind into one of the Italian Garden pools. Excited by this irresistible colour, a pair of Coots made a beeline for it.
There are no berries left in the rowan trees. A Mistle Thrush ...
... and a Blackbird ...
... were picking up fallen berries from the ground. A Redwing ...
... had been doing the same, but my arrival disturbed this very shy bird and it flew into a tree. This gave a glimpse of its red wings.
