Young Grey Herons getting restless

A Great Spotted Woodpecker called from an oak tree in the leaf yard.

A Dunnock perched for a moment in a holly tree.

The female Coal Tit in the Flower Walk came out to be fed.

Long-Tailed Tits hunted in a hawthorn tree.

One of the Little owlets near the Round Pond looked out of a hole in the dead tree.

They use several holes in this tree to enter and leave their nest, and this hole is on the other side from where their father was perched in a horse chestnut, so he couldn't see me looking at the owlet. So he stayed silent instead of shouting curses at me as he often does.

One of the owlets at the Serpentine Gallery could be seen deep in the shade of the sweet chestnut tree.

It hissed to encourage a parent to feed it. The presence of people and dogs in the park largely prevents them from being fed in the daytime, so they have to put up with being fed at dawn and dusk. Sometimes a parent manages to find a caterpillar in a tree to keep them going through the day, and they don't seem to be starving.

Their mother was on the other side of the tree. She's very calm about being photographed.

The young Grey Herons in the nest on the island have reached the stage where they stand on the edge of the nest and flap their developing wings. Soon they will be climbing around in the trees.

The pigeon-eating Lesser Black-Backed Gull now doesn't spend much time in his original hunting ground at the Dell restaurant, as the pigeons here have become wary. But he was there today, running after a pigeon which got away.

I could only see two Cormorants, this one on the Long Water and another at the Serpentine island. Evidently this year's young fish haven't grown large enough to interest them.

The young carp in the Italian Garden fountains are about 2 inches long.

This is just the right size for Great Crested Grebes to feed to their young, but there are very few grebes in the park at present. I don't know what has gone wrong here this year. It might be partly due to the increasing number of pike in the lake.

The young Coots from the nest in front of the Peter Pan statue are now mostly finding their own food, though they will beg when a parent is around.

A Red-Crested Pochard drake at the Vista was fully in eclipse but still looking quite smart, with female-pattern plumage contrasting with his male red bill and eyes. Females have brown eyes and a greyish-brown bill with a hint of pink around the edges.

A Speckled Wood butterfly basked in the grass. There are lots of these around at the moment, as well as Meadow Browns.

Duncan Campbell found some more interesting butterflies, a Large Skipper (Ochlodes sylvanus) ...

... and an Essex Skipper (Thymelicus lineola).
