Today's best picture is by Tom Bell, a wonderful shot of a Treecreeper beside the Long Water.
It was a grey windy day. The male Little Owl looked out of his hole for a few seconds, didn't like what he saw, and went back inside.
The female of the prolific pair of Egyptian Geese at the Round Pond was also inside again, sitting on her nest in the usual oak tree.
A pair of Wood Pigeons in the leaf yard seemed fond of each other.
A Grey Wagtail added a splash of colour to a dull day, looking for insects on a bit of floating wood near the small boathouses.
The pigeon-eating Lesser Black-Backed Gull was preening on the edge of the Serpentine before stalking his next victim.
A Black-Headed Gull was playing with a tatty bit of aluminium foil, which made an interesting rustling noise when shaken.
A Rose-Ringed Parakeet was climbing down to reach a fat ball hung in one of the catalpa trees between Peter Pan and the Italian Garden.
On the other side of the path two Robins were singing loudly at each other.
This fungus growing on a plane tree at the Lido has been identified by Mario as a Shaggy Scalycap (Pholiota squarrosa).
Update: Mike Meilack got a good picture of a Kingfisher on the dead willow tree next to the Italian Gardens.
