One of the Great Crested Grebes from the nest on the fallen poplar came too far up the Long Water for the liking of the pair from the reed bed, and there was a fight, with two of the chicks watching with interest -- the third one was still coming up when I took this picture. As usual, there was a good deal of splashing and shrieking but no one was hurt, and the intruder was driven off towards the bridge.

The grebe chicks from the poplar are still quite small and haven't grown their flight feathers yet.

The older set of chicks are already brief making practice runs for the difficult business of taking off, and I hope to catch one on camera soon.

There was another scrimmage on the Serpentine, of Herring Gulls and Lesser Black-Backed Gulls, almost all juvenile, trying to grab a slice of bread. A smaller Black-Headed Gull hovered above like a scrum half waiting to seize anything that came out.

More Shovellers have arrived on the Long Water. The males are still not fully out of eclipse and still have some speckled plumage.

A Carrion Crow was eating rowan berries in one of the trees on Buck Hill.

In the next tree a Magpie was doing the same.

This demonstration of corvine power had driven out the Blackbirds, Mistle Thrushes and Starlings.

I couldn't find any Reed Warblers in the reed bed near the bridge, and they may already have set off on their long migration. A small brown bird in the reeds near the Diana fountain turned out to be a Wren. These are residents.

Both adult Little Owls were on view. The male had reclaimed his favourite branch on last year's nest tree ...

... and the female was in her usual place in this year's nest tree, as usual quite hard to see among the leaves.

Although they are a pair, outside the nesting season they like to keep their distance.
