On a dark, chilly day of persistent rain, the most notable sight was hundreds of Swifts over the Serpentine, some of them at high altitude, others skimming the water. As usual, there were a few House Martins mixed in with them, though I only saw one Swallow.
The rain didn't deter some Starlings from making themselves even wetter.
Only three of the brood of four Egyptian Geese survive, but they include the blond one, on the left here showing clear signs of growing into the unusual white-headed pattern with no eye patch. There are two Egyptians like this in the park, both female but this may be chance. The young ones are quite large now.
So far, there is no sign of any other broods of Egyptians in this difficult year. I have never yet managed to see an Egyptian Goose nest. They are said to be in tree holes; they would need a pretty big hole, but of course there are lots of hollow trees in the park for them to choose from. Their habit of perching on top of dead trees seems to have more to do with display than with actually making a nest.
There are two broods of Greylag Geese: one of three (originally four, they lost one), and another of seven, which I photographed on Sunday. Today they were both near the Serpentine island, but keeping separate. Canada Geese often share their child-care arrangements, but I haven't seen Greylags doing this.
There was a Goldcrest near the Serpentine bridge.
It must be quite difficult for such a small bird in heavy rain, where every drop threatens to completely douse it. No wonder they are so often seen in dense evergreens that provide some degree of shelter.
A Treecreeper was also visible on the usual oak tree at the southwest corner of the leaf yard.
They are so often on this tree that I think they must have a nest higher up it, and out of sight. There was also a Great Spotted Woodpecker in an adjacent tree.
Sorry that this has been a dull day's reporting. I hope that there will be more action, and less rain, tomorrow.
