The Mute Swans were leading their cygnets around patches of algae on the Long Water.

The Canada gosling was seen alive this morning, on the fallen horse chestnut tree. We looked carefully for it but couldn't find it. I don't think there is any way of catching this elusive little bird and presenting it to its real mother at the other end of the lake.

The swan in the net east of the Lido had was dozing peacefully when a rat tried to get into her nest. She woke up and pecked at it, and it ran off.

The Black Swan was doing a curious shuffle along the slippery edge of the Serpentine. He
is moulting, earlier than the white ones, but of course he is Australian and they do things differently there. You can see the new feathers beginning to emerge on his wings.

Blondie the Egyptian Goose still has her seven young. Their survival is due more to the small number of Herring Gulls on the lake at the moment than to her intermittent attempts at child care.

When the Canada gosling climbed on the swan's back, we thought it was unusual for a goose, but it seems that young Egyptians do the same thing -- though they are not really geese, and their nearest British relatives are Shelducks.

 The Bar-Headed Goose is still here. It was in a mixed flock of Greylags and Egyptians near the Dell restaurant, occasionally being chased by the larger Greylags and chasing the smaller Egyptians.

In this dark and distant picture, it looks as if the Great Crested Grebes at the island have two chicks. But this was the only picture of a sequence that showed the second, and it may be a trick of the light.

The two pairs of grebes at the north end of the Long Water, whose territorial frontier is the line of posts, were having a brisk fight after one pair crossed the border. The fourth grebe was just out of the frame in this picture.

A Pied Wagtail was collecting insects beside the Serpentine for a fledgling waiting on a moored pedalo.

A Feral Pigeon discovered an unguarded bowl of chips at the Dell Restaurant, and ate several before their indignant owner noticed and chased it away.

There was a Dunnock in a tree on the west side of the Long Water.

The male Little Owl was on his favourite branch in the chestnut tree.

We hope to see some owlets soon.

This bug was on a post in the reed bed at the east end of the Serpentine. I thought it was a Common Green Shieldbug, Palomena prasena, that was being slow in changing from its winter brown colour to its summer green.

Update: But, as so often, I was wrong. David Element tells me it's is a Dock Bug, Coreus marginatus, 'one of the larger squashbugs'. So glad not to have disappointed readers with one of the smaller squashbugs.
