But there was plenty to see on a sunny day. One of the Little Grebes was resting under the dead willow tree near the Italian Garden, hard to photograph through the twigs and this is the only completely unobstructed view I got.
The Little Owl was looking out of the hole in the oak tree.
When I came back later with Mario to show him the tree, the owl obligingly came out again.
The male Tawny Owl was in his usual place by 3.30.
And there were eight Redwings on the patch of leafmould under the plane trees on the path near the Speke obelisk.
Nearby a piece of bread was lying in the grass. A Magpie and a Wood Pigeon were both heading for it when a Jackdaw whizzed in and grabbed it. It is unusual to beat a Magpie at a quick snatch, and the foiled bird worked off its annoyance by poking furiously in the grass for a worm.
The pair of Starlings who own the nest hole in the Tawny Owls' tree were perched on a bramble stem, looking fine in the sunlight.
A Mute Swan was asleep next to the Dell restaurant, looking like a huge meringue.
Blue Tits are so common that it is easy to forget what bright little birds they are. Compared to the sober colours of most British birds they look quite tropical.
Update: Joe Beale saw the Scaup on the Serpentine about midday. Wendy, who runs the Wino Wendy's Wildlife World blog, was in the park today and we had a brief natter. She has written about her visit, with some good pictures, here.
