There was a lot going on in the yew tree near the bridge, with a couple of Goldcrests flitting about ...
... uttering sharp cries of annoyance because a Coal Tit was chasing them. It's a bit sad to be so small that you can be pushed about by a Coal Tit.
A pair of Long-Tailed Tits were leaping from twig to twig in a nearby tree.
There was a Treecreeper in the yew too, photographed here after it flew into another tree where the light was better.
Underneath, a Robin was eating a worm. It was biting off lengths and swallowing the unfortunate creature a piece at a time.
The Great Crested Grebes' nest at the east end of the island has been occupied for several days.
This place is hard to see, as it is inside the line of floating baskets of plants that surround the island. You have to stand near the line of posts and peer into the shadows under the bushes.
The Black Swan was on the Serpentine by himself, preening his wings.
One of the Pochard-Tufted Duck hybrids was diving for food on the Long Water near the Italian Garden.
A Grey Heron was scratching itself on a post at Peter Pan.
This is the heron that has a broken toe that has set crooked and sticks up at an angle. The heron finds this useful as a scratcher.
The Little Owl in the oak tree near the Albert Memorial was also scratching itself.
But the one in the lime tree near the Henry Moore sculpture was content to stare at us.
