The Sparrowhawks were flying around the park greenhouses calling to one another.  One perched in a windy treetop.

I couldn't find the Kestrel, but at one point a Hobby flashed through the trees.

The female Little Owl stared down from her nest tree. She is no longer worried by the camera.

A Herring Gull had difficulty swallowing a large crayfish, but managed. It's amazing to think that the muscles in its gizzard can break up this spiky morsel.

A Black-Headed Gull ate a smaller and softer-shelled crayfish without difficulty.

The pigeon-eating Lesser Black-Backed Gull had found a more nutritious meal in his usual place at the Dell restaurant.

A pair of Black-Headed Gulls moaned affectionately at each other and walked side by side. They have now mostly lost the dark head of their breeding plumage.

The three Great Crested Grebe chicks from the west end of the island are now noticeably larger. I put a 10-second countdown on this video because YouTube has difficulty with shots of moving water.

The teenager at the east end is now almost as large as its parents.

The number of Cormorants on the lake is increasing as this year's young fish grow large enough to interest them. There were four on the posts at the Serpentine island.

The Black Swan was dredging up algae at the edge of the lake.

Three Mute cygnets rested confidently in the middle of the Serpentine Road, expecting people to go round them.

Duncan Campbell, always on the lookout for interesting insects, photographed an Ornate-Tailed Digger Wasp (Cerceris rybyensis) attacking what he thinks is an Orange-Legged Furrow Bee (Halictus rubicundus).

Tom was at Rainham, where he found a Common Lizard ...

... a Painted Lady butterfly on a buddleia flower ...

... and a Hornet Hoverfly (Volucella zonaria).
