A Cormorant fishing in the shadows under the bridge caught a large perch, and turned it round to swallow it head first and avoid being spiked by its spiny dorsal fin.
Another Cormorant, replete after a day's fishing, was heading out of the park to spend the night downstream on the Thames.
The Great Crested Grebe family on the Long Water, also busy fishing, were annoyed by a Black-Headed Gull trying to grab their fish. The father chased it away.
A group of Greylags were having a communal wash on the Serpentine, diving and chasing each other around in a good-natured way, and of course turning upside down and waving their orange feet in the air.
It's surprising to see these big birds diving and staying under for several seconds.
One of the hybrid geese had also been bathing, and was flapping its speckled wings.
Most of the Canada-Greylag hybrids on the lake are awkward looking, but this one is quite elegant. However, it lost its poise when it slipped on the algae at the edge of the lake and fell flat on its belly.
Some Starlings on the Round Pond were also having a bath together.
This is the same Lesser Black-Backed Gull as yesterday, in the same place on the edge of the Serpentine, but with a new toy, a decayed goose feather left over from the big moult in June.
The male Little Owl was basking in the sunshine on his favourite branch.
When I went past the tree later there was a lot of calling and I went to see what had happened. The owl was in the other tree, but I couldn't find anything amiss. Probably he had been annoyed by some kind of crow.
Sadly, the tree people have hacked up the beech tree next to the damaged Tawny Owls' tree, removing the other places where they liked sitting. Heaven knows where the owls are now.
I really don't understand these people's strategy. They assault what seem to be healthy trees, while huge bits fall off trees that they have overlooked. For example, everyone knew that the Tawnies' nest tree which collapsed recently was in a dangerous state: there was an enormous hole right across the hollow trunk from side to side that you could see through.
