The swan invasion continues

The invading Mute Swans from the Serpentine continue to advance up the Long Water, and had brought their five cygnets well past the Vista.

Rival males had a brief fight before going back to the usual threat display cruising side by side with wings raised.

But these weren't the male invader versus the resident male. It was, I think, the resident male attacking another swan that had strayed on to the lake, to show how tough he was. He daren't attack the invader, who is the terror of the lake --  and was not impressed, calmly preening on the edge.

Mute cygnets are not mute at all: they are quite noisy, squeaking plaintively.

Also at the Vista, a pair of Greylag Geese had a faceoff with one of the resident Moorhens. The cause of the dispute was a tiny amount of oatmeal on the kerb.

The female Mallard by the Triangle car park is now down to her last duckling.

There was a slightly better view of the Great Crested Grebe on the nest by the bridge.

I now haven't seen the grebes with chicks for two days running. I don't think this is necessarily bad news, as if they had lost the chicks we would have seen them alone. Probably they have just found a good place to lurk in shelter.

The old Grey Heron by the Henry Moore sculpture was enjoying a good scratch.

There was just enough sunshine to encourage a Feral Pigeon to bask ...

... but the Little Owls at the exposed Round Pond were staying indoors. The female looked out of the back entrance of the nest tree.

The female at the Serpentine Gallery could just be seen through a gap in the leaves of the lime tree.

The male Peregrine on the tower had an almighty yawn.

A Reed Warbler below the Italian Garden was feeding chicks, and kept coming out of the reeds to catch insects for them.

A Gatekeeper butterfly perched in the long grass near the Round Pond, the first one I've seen this year.

Buddleia is sometimes called 'butterfly bush', and indeed butterflies love it. Here are a Red Admiral and a Meadow Brown on the same flower head.

A clump of Scarlet Beebalm in the Rose Garden lived up to its name by attracting Common Carder bees. There were at least a dozen climbing all over it.
