The Great Crested Grebes who lost their nest under the willow tree near the bridge have managed to get going again, and have built a new nest under the same tree a few yards away -- they couldn't return to the same place because some Coots have nabbed it. It is visible from the shore but not in such a good place for photographs, as it is mostly obscured by twigs and leaves. Let's hope they have better success this time.
Meanwhile there is a lot of action at the bridge. The resident grebes are hauling bigger and bigger fish out of the basket ...
... and intruders are being made to leave in a hurry. This one was so flustered by its hostile reception that it actually flew away for some distance.
There was a Common Tern fishing on the Serpentine.
It called frequently, but I couldn't see a mate or juvenile anywhere. These terns spend a good deal of time on the Grand Union Canal which, despite being murky, is teeming with fish, and only come down to the park occasionally.
Near the Queen's Temple I heard the call of a Hobby and it shot between two trees with a Carrion Crow in pursuit. It didn't come back into view.
The Song Thrush nesting near the Serpentine Gallery is becoming remarkably insouciant about humans. It stood on the edge of the busy path for some time as people passed within a couple of feet of it. It acted as if it thought it was invisible -- which, from the point of view of most of the people, it was.
The Coots who have been harassing the nesting Mute Swans below the Italian Garden have now built a nest in the reeds just two yards away from the swans' nest. One of them was sitting on it, uttering irritable chippy cries. They really do seem to enjoy being aggressive.
