The dominant Mute Swan at the west end of the Serpentine sailed into a group of swans that were feeding at the landing stage. One of them refused to flee immediately, and there was a fight.
A pair of Shovellers were revolving around each other on the Long Water. The turbulent wake of one bird brings up tiny water creatures for the other to shovel up and filter out with the rows of plates inside its huge bill.
A young Great Crested Grebe on the Long Water did the shrug that all grebes do to settle their feathers comfortably.
Just when you thought the Moorhens in the Italian Garden ponds had finished breeding, this young chick appeared. I think there's only one.
The rescued Grey Heron was at the edge of the Lido restaurant terrace having a drink and hoping for scraps.
There is another young heron in the area, which was in the Dell. It looks so like the first one that I thought it had flown down while I was walking around the edge, but when I got back up again the first heron was still at the restaurant. On close inspection you can see that the white feathers under its chin are brighter and reach farther down its neck.
A Carrion Crow was having a splashy bath near the island.
The Coal Tits near the bridge emerged shyly from the bushes to be fed.
A flock of Long-Tailed Tits passed by and paused in a holly tree.
A few Mistle Thrushes flew into the rowan trees at the top of Buck Hill.
The Little Owls near the leaf yard were hard to find, as usual on a sunny Sunday when the park is busy. But a third visit found the female owl in the nest tree.
The purple flowers on the edge of the Dell are popular with bees of several kinds. This is a Buff-Tailed Bumblebee.
