We are sure it is him, because Paul Turner photographed him earlier when he was sitting higher in the tree and the distinctive white patch on his chest was visible. The owl was understandably restless in the presence of a rival, moving from branch to branch.
The male Little Owl also came out to enjoy the sunshine.
A pair of Blue Tits have started nesting in the usual gas lamp post at the back of the Lido swimming area. The entrance to the nest is at the bottom of the gas pipe, where there is a hole leading into the cast iron post.
Presumably the nest itself is inside the ornamental bulge in the post just below this hole.
A Dunnock was alternately singing and preening himself on a tree near the Queen's Temple. Here he is trying to do both at once.
We have had rather a lot of pictures of the Robin family near Queen Caroline's memorial, but they are irresistible. The young birds were flying from one side of the path to the other, loudly pestering their parents for food, and taking absolutely no notice of the people walking by.
The bright yellow gape of young birds stimulates their parents to feed them. So does the rapid vibration of their wings, which you can see here.
The pair of pigeon-eating Lesser Black-Backed Gulls were sharing their latest kill near the Dell restaurant (where pigeon is not on the menu).
