This Grey Heron's nest on the Serpentine island was built long after the others, and it was not clear whether anything was going on there. But today there was the sound of a chick clacking its beak, begging to be fed.

The heron that hangs around the Dell had abandoned its attempts to get food from the restaurant, and was doing an honest day's fishing at the Serpentine outflow.

A Common Pochard has ducklings on the Long Water, here seen looking down from the bridge. This is the first time I have known this species to breed here (though two Red-Crested Pochard ducklings fledged successful some years ago).

There were five Red-Crested Pochards on the lake, all drakes, but only four would get into the same picture.

The new Egyptian Goose family still has seven goslings ...

... and the Greylags are hanging on to their six.

There is a Coot nest on a moored pedalo. Sadly, it has no chance of success, for when the chicks go into the water they will have no way of climbing up again. Also, it was surrounded by Herring Gulls, whose dropping streak the boat. Thanks to the people at Bluebird Boats for taking me out to see it.

The Coots evicted from their nest under the willow tree by a Mute Swan have returned to it, and are doggedly building it up again.

The pigeon-eating Lesser Black-Backed Gull had caught a Feral Pigeon next to the bridge, so there was a top view of him enjoying his lunch.

The Little Owl near the Albert Memorial was in a place where she was very hard to see, let alone photograph.

This is one of the two Grey Wagtails that have taken up residence in Notting Hill Gate Underground station. The station is open to the air, but it's a long way from their preferred waterside habitat.

The large plaster eagle in Orme Square just north of Kensington Gardens puzzles local historians.

It was put there in the early 19th century by the property developer Edward Orme, and there are also reliefs of eagles over two doorways here. There are eagles on the Orme coat of arms, but the ones here don't match their pose. It was put up not long after the victory at Waterloo, but it doesn't look like the eagle from a captured French military standard either. Maybe Orme was just keen on eagles and not too fussy about details.

An arum lily near the Diana fountain had two flower beetles on its spadix. Apparently there are 4000 species of flower beetle, and I have no idea which it is.

Mark reports from St James's Park that the young Great Tits are now coming to his hand.

They're ahead of the ones here, which are still expecting to be fed by their parents.

He also found a Cinnabar Moth. There are seldom seen in central London parks, though I did find one in Kensington Gardens several years ago.
