Yesterday Fran was walking past the oak tree near the Albert Memorial where the Little Owls nested. She saw two faces peering out of the hole, and took this picture.

But she had the short lens on her camera, and by the time she had switched over they had vanished back into the tree.

This morning I went past with a long lens, and amazingly there were again two owl faces in the hole. And they weren't the adults we have seen here before, they were owlets. It was a dull grey day, but I got a photograph.

In the chestnut trees near the leaf yard, only the male Little Owl was visible.

In this picture he looks as big and round as his mate, but that is because he was fluffed up on a chilly damp morning. You can tell him from the female by the larger area of pale feathers at the inner edges of his eyebrows. (This is not the sign of a male owl, it's just a difference between individuals.)

A Great Black-Backed Gull visited the Long Water and stood on the posts at Peter Pan, dwarfing a Herring Gull and a Lesser Black-Back.

The Coots nesting under the Bluebird Boats platform have managed to keep three chicks from the gulls.

One of the young Moorhens at the east end of the Serpentine had stopped begging for food from its parents and wandered off to forage in the debris under the entrance ramp to the restaurant.

The food requirements of a Moorhen are pretty simple: just about anything that has the slightest nutritional value. By its own standards it was doing well.

I couldn't find any Mandarin ducklings. But the teenager from the earlier brood was on the Long Water. Here it is on a post at the Vista. It can now fly well, and I found it again later on the other side of the lake by the Henry Moore sculpture.

Although the Mallard drakes are going into eclipse, they are as lustful as ever. One was chasing a female over Buck Hill. She dived and fell back out of his field of view and landed in a tree while he charged on. She stood there looking rather pleased with herself.

The Black Swan saw me, came over, and called loudly for a biscuit.

He knows I walk round the lake, and intercepted me on the other side for a second biscuit.

There was a great mob of Greylag Geese with goslings on the south side of the lake.

The number of young geese of all species is now over 35.

There haven't been many sightings of Grey Wagtails recently, but Tom found one yesterday. It's a young one, with only a hint of adult bright yellow under its tail.

A Magpie near the bridge was rummaging through a pile of lawn mowings looking for insects and worms.
