Grey Wagtail on the waterfall

A young Grey Wagtail at the top of the Dell waterfall was catching small creatures as they were swept over the edge.

A still picture shows that they were midges resting on the surface of the water.

A Moorhen lower down in the stream was hunting for the same creatures -- and for just about anything as they are not fussy eaters.

There was a strong wind, especially over the exposed Round Pond, and I didn't think the Little Owl would be out. But there she was, on her usual sheltered branch.

I haven't seen the Hobbies for two days. Maybe they are already on their way to Africa. There has been no sign of the Peregrines either, and I guess that the young ones have been thrown out of the territory and their widowed father is off looking for a new mate.

This is the same Robin in the Flower Walk as in yesterday's picture, and just as impatient to be fed instead of photographed.

Another Robin in the corkscrew hazel bush will fly down and take pine nuts from the ground.

A Jay in an oak near the Henry Moore sculpture waited to swoop down and snatch a peanut from my hand.

A Jackdaw appeared in a new place, near the boat hire platform, but it knew me and came down for a nut. I think the brown leaves on the small lime tree are due to its being a sickly tree, not because of the onset of autumn.

But there are already plenty of fallen leaves after a dry spell. A young Wood Pigeon browsed in the grass near the Serpentine Gallery. It still doesn't have a adult's white neck ring, but its originally dark eyes are starting to lighten.

Pigeon Eater is beginning to go into his winter plumage, with grey flecks on his head.

A young Herring Gull fished up a bit of brick from the bottom of the lake and played with it.

The southeast corner of the Serpentine is full of brick rubble. Some years ago there was a silly Red Bull birdman event in the lake, and they spilt several tons of rubble which they had been using as ballast for the platform. The park management slackly didn't make them clear it up.

The Grey Heron chicks were hunkered down in their nest as the wind blasted over them.

The wind had also brought the Great Crested Grebe family together to shelter in the lee of the island.

During a calmer moment, the grebes at the east end of the lake had a little display.

The Long Water is sheltered by trees, and the family here were not disturbed.

A Greylag Goose family were eating reeds.

There has been a late boom in the Common Carder bee population, and they are particularly fond of the catmint patch in the Rose Garden.

A robot dog could cope with stepping down a kerb on to loose sand, but having to step up on the other side of the road brought it down with a crash. It was sent back to scan the obstacle, and this time managed to walk up it. A real dog was not amused.

The robot is a Unitree Go2, and if you want one it will set you back over £7000.
