During a brief sunny spell in the morning, the Little Owl near the Albert Memorial made a welcome reappearance in the oak tree.

It soon started raining, and she went back into the hole.

One of the young Pied Wagtails looked for larvae in the debris on the edge of the Serpentine.

A young Great Tit ate a pine nut which I had supplied to its father. The father came back for one for himself. The young birds will soon be getting their own food.

The Starlings at the Lido restaurant have had a successful breeding season, and there are brown young birds all over the tables on the terrace.

A young Carrion Crow demanded food from a parent.

The year-old Grey Heron which hangs around the Dell and the Dell restaurant examined the pool at the top of the waterfall to see if there were any fish in it, found  none, and flew off.

Unknown to the heron, there are never any fish in this pool. It's filled by a pump at the bottom of the slope to make the waterfall look more impressive. The outflow from the Serpentine joins the fall lower down.

The four chicks on the Coot nest under the balcony of the Dell restaurant were being fed.

Ahmet Amerikali was in Southwark Park, where he has found an unusually visible Little Grebes' nest -- mostly these are well hidden. In these remarkable pictures, a second chick has just hatched. Its mother eats part of the eggshell to top up her calcium level ...

... and takes the rest away to dispose of at a safe distance, so as not to alert predators to the nest.

He also took this pleasing picture of a Moorhen chick waving its little wings as it is fed.

The six Greylag goslings on the Serpentine are getting bigger. Their parents preened, and the goslings copied them.

The two Bar-Headed-- Greylag hybrids that have come from St James's Park to the Serpentine to moult are waiting for their flight feathers to regrow.

This Egyptian Goose is just beginning to get its wing feathers back -- you can see them emerging in their blue wrappings.

In coming to Britain these African birds have lost any sense they ever had of the passing of the seasons, and they moult (and breed) at different times. This one's complete set of flight feathers looks to be in brand-new condition, so it must have moulted already.

The two female Mandarins haven't moulted yet, as you can see from their neatly crossed primaries.

There is a pretty mallow plant under a holly tree near the Italian Garden.
