Nothing unusual to see today, apart from the reliable Bearded Tits at the Diana fountain.

They are still drawing a small crowd, not only of serious birdwatchers and photographers, but of ordinary people who have heard of them and have come to see what the fuss is about. Not only are these casual visitors charmed by the beauty of the little birds, but perhaps the sight sparks an interest in birds that may develop. In this way a couple of rarities are doing their bit for the welfare of all our birds.

The Tawny Owl was not to be seen, perhaps sheltering from the cold inside the nest tree. A Little Owl was seen -- not by me -- at the Serpentine Gallery again. I have not managed to see this bird, despite going past the gallery daily. But seeing Little Owls is a matter of luck. Since there have now been several sightings of one or two of them at the gallery, it seems possible that these are a different pair from the ones in the leaf yard. When the Little Owls were first seen in Kensington Gardens last spring, there appeared to be three pairs of them, though it was impossible to be certain that it wasn't one pair ranging around looking for a tree to nest in.

Several hundred Greylag Geese flew from their grazing ground on to the Serpentine.

They may have been disturbed by a dog, or it may simply have been one of those committee decisions that flock of geese take by honking and copying others until there is a majority. They have a well organised society, taking it in turns to be the watch-goose while the rest of the flock have their heads down in the grass. When they are flying in a V, they also take turns to be the front bird, the only one who doesn't get a tow from the slipstream of the bird in front.

The Mute Swans are still threatening and chasing each other, and one was driven off the lake entirely. Here one of the young swans adopts a very adult threat posture. Actually it wasn't threatening another swan, it was just swaggering about playing the tough guy.

The four young Egyptian Geese at the Round Pond are still in good order amid the ice and snow, always attended by their solicitous parents. Here the smallest of the brood stands as his sibling ruffles up his feathers in that peculiarly untidy Egyptian way.
