Only time for a quick visit to the park today. But the male Little Owl was on his favourite branch, much more visible than the female's usual place ...

... and so was the young Robin in the shrubbery in the Rose Garden.

This isn't the first time we've seen the young Pied Wagtail here at the edge of the Dell restaurant terrace. It's an ideal spot, with the food split by diners attracting insects for the bird to catch, but separated from the humans by a low fence.

The Great Crested Grebe under the willow near the bridge sat peacefully on its stolen nest.

The pair of Coots in the Italian Gardens fountain ruthlessly ripped up water lilies to make their nest. It's probably too exposed to succeed.

I think that this Egyptian family on the Serpentine is the one that lost a gosling when it strayed off ...

... and joined this family, whose own goslings are older and larger. It's on the right of the picture, between three of the bigger ones.

The two ducklings of the Mallard on the Serpentine are now large enough to have a fair chance of survival.

Tom sent some good pictures from Richmond Park. A female Kestrel waited on a stump for a mouse to come into view or, failing that, a grasshopper.

The Little owlet was on the usual dead oak tree.

Here's his video of it. You'll never see the perfectly camouflaged owl until it moves.

A Grass Snake swam across one of the Pen Ponds.

Two White Letter Hairstreak butterflies on an oak twig. The 'white letter' is the rather vague W on the hind wing.

There are other alphabetical insects: the Silver Y moth, the Hebrew Character moth, and the familiar Comma butterfly. The budding acorns on the twig are deformed by insect infestation and will not develop, a condition also seen in Hyde Park, but some of the acorns still develop normally.

Update: just told that it's a Purple Hairstreak. But both species have the W mark.
