The Tawny Owls were being harassed by three Mistle Thrushes, of which this is one ...
... and half a dozen Ring-Necked Parakeets, so the whole area was resounding with rattles and squawks. They took no notice at all; owls must be inured to such things. The male owl lazily opened one eye when I rustled the fallen leaves as I approached, a much more interesting noise to a hunter of mice.
The female slept peacefully through the whole episode.
There were more Mistle Thrushes on the rowan trees on Buck Hill, though they wouldn't move into a position where I could get a picture. So here is a shot of one of the Starlings, hastily grabbing a couple of berries before flying away with the rest of the flock.
Two pairs of Great Crested Grebes were still making a great show of defiance in their territorial squabble near the bridge. The display involves frequent diving, but why not have a snack while you are down there?
I don't know whether this object is a fish looking dark under water, as ordinary silver fish do, or whether it's a crayfish. In any case it was edible, and was eaten.
A discarded plastic bottle on the Serpentine gave a Moorhen something to play with.
Moorhens are not usually thought of as birds that play. Their life is too much of a hard scrabble for that. Predators and savengers -- falcons, hawks, gulls, and for some reason Common Swifts -- are the birds that are commonly seen playing. But there is no reason why a Moorhen shouldn't have a bit of fun too.
