On a windy day the Pochard-Tufted Duck hybrid was looking ruffled as she crossed the Long Water.

The male Tawny Owl dislikes being blown about and had spent the morning indoors. When the wind dropped and the sun came out in the late afternoon he emerged, and was then annoyed by a strong contender for the Squirrel Nutkin Award for Foolhardy Behaviour. A couple of inches nearer and it would have got slashed by a terrible talon.

Today's plaything for the young Herring Gull on the Serpentine was a mouldy tennis ball, which could be brought out of the water and put at the top of the sloping edge and would roll amusingly back.

In case this makes the gull look enormous, I should point out that it was one of those miniature tennis balls which people throw for small dogs to retrieve.

There was a genuinely enormous gull on the Long Water, the adult Great Black-Backed Gull on one of its occasional visits.

They can have a wingspan of over 5 ft 6 in (166 cm).

The usual Cormorants were fishing around the wire baskets near the bridge. Here water cascades of the head of one of them as it looks up from peering under water.

Both Little Grebes were after smaller prey under the willow tree next to the Italian Garden.
