Both the Little Owls at the leaf yard were out of their nest hole. The female was on a branch above it ...

... and the male was in the next tree.

There was no sound of owlets, but it's too early to be sure there aren't any. I haven't heard anything near the nesting places of the two other pairs of Little Owls either.

Another gas lamp beside the Serpentine has a Blue Tit nest in the cast iron post. You can hear the nestlings calling while the parents bustle in and out to feed them.

A young Starling followed its parents around at the Lido restaurant. It's the same bird in each of the three shots.

Earlier this year a pair of Great Crested Grebes began a nest in the reed bed on the east side of the Long Water, but abandoned it. Now they've started again, with a better chance of success as there are now some small fish to feed the chicks.

One of the grebe chicks at the island was given a perch. This had to be turned round to be offered head first, because its spiny dorsal fin made it hard to swallow.

The Coot chicks under the balcony of the Dell restaurant are now swimming around. There are only five, and it looks as if the remaining eggs are infertile.

There's just one chick left in the nest perilously sited on top of the weir at the lake outflow. But at least the parents have tastefully ornamented their nest with flowers.

The Coots on the solar cell platform at the Round Pond still have their two chicks, protected by the bank of cells overhead. There were no gulls on the pond today.

This was also good news for the Egyptian Geese. They pair with the younger brood still have seven goslings.

An Egyptian Goose beside the Serpentine kept between her goslings and a hungry Lesser Black-Backed Gull.

The gull was also eyeing some Coot chick on the far side of it. While waiting for a chance, it had a wash.

The number of Canada goslings on the Serpentine is now up to 30. Here are the newest three.

The Greylag Goose families on the Serpentine came ashore to graze.

An unknown goose reported on the Round Pond turned out to be the Bar-Headed Goose from St James's Park, which had moved up from the Serpentine.

The older brood of four Mute Swan cygnets on the Serpentine were in open water under the watchful eye of their mother. The younger ones were preening on the island.

The female swan on the Long Water saw off a Grey Heron that had got too near her four cygnets.

It's very hard to know what is going on in the well hidden herons' nest on the Serpentine island. In this clip you can hear cries of what seems to be fury, and the clacking sound of a young heron begging to be fed. A few seconds later a heron -- young but a teenager rather than a nestling -- can be seen on the lower nest, which the other pair of herons abandoned a while ago after two unsuccessful nesting attempts.
