One of the young Tawny Owls appeared again in the usual chestnut tree near the leaf yard, more visible than usual in the thick foliage.

The Little Owl was also out in his usual place, dozing in the sunshine.

There was a brief glimpse of a Hobby over the Vista, heading towards the avenue of tall plane trees south of the Physical Energy Statue.

I looked carefully at the trees but couldn't see where it had perched.

There is still one Common Tern on the Long Water. Here it is stretching its wings before flying off on a fishing expedition.

A Great Crested Grebe chick was again dimly visible in the nest on the Serpentine island, but we shall have to wait till their parents take them out before we can get a proper view of them.

The grebes on the nest on the east side of the Vista had just changed places, and the male enjoyed a good splash before going fishing.

But one of two Mallard ducklings on the Long Water had a much bigger splash by swimming under a jet of water spouting from the marble fountain.

In the reeds beside the fountain there was a Common Darter dragonfly (Sympetrum striolatum).

There were also plenty of Emperor dragonflies and Common Blue damselflies.
