It seems that there is only one chick in the Great Crested Grebes' nest on the Long Water. Here it is being fed a fish, an event that would certainly have brought out others if there were any. As usual this is an extremely long shot from across the lake.

The three grebe chicks at the Serpentine island were in good form, calling loudly for food. The family had moved to the west end of the island.

There was another young Green Woodpecker, this time in the long grass between the leaf yard and the Vista, where there has been a pair of adults for some years.

Just outside the railings of the leaf yard, a young Dunnock was poking around on the hard trodden ground.

This is one of the pair of Coal Tits near the bridge in what seems to be their nest tree, a small yew on the triangle of grass and shrubs near the southwest corner of the bridge. They come out for food and keep returning to the tree.

A young Reed Warbler was calling from the reed best east of the Lido. This means that there are three families on the lake. The place is impossible to photograph, so here is one of the birds from the reed bed near the bridge.

One of the young Little Owls was in last year's nest tree.

At the top of the tree, a pair of Mistle Thrushes were rattling disapproving at it.

There was a Large White butterfly on a corn marigold in the wildflower patch at the back of the Lido.

Mario the fungus expert drew my attention to these mushrooms. They are Silky Rosegills, Volvariella bombycina, and are uncommon, especially in central London. The mushroom emerges from an egg-like structure, of which you can see the remains under the upper one.

They were growing on a decaying horse chestnut tree at the northwest corner of Buck Hill near the children's playground. Some of these trees are in quite bad condition with a lot of rotten wood at the base of the trunk.
