Two exciting discoveries -- but not by me, and no pictures.
A male House Sparrow was seen on the feeder at Kensington Palace on Friday. This may sound terribly ordinary, but House Sparrows disappeared from Central London in 2000, and only one has been seen in the park since then, last year. Sparrows have also been seen in Fulham recently. Until now you had to go westwards the whole way to St Mary's Churchyard, on the west edge of Kensal Green Cemetery, to see one.
Also, a Water Rail was seen yesterday in the triangular bit of trees and scrub at the southwest corner of the bridge, near where the Cetti's Warbler has been. This is a very difficult place to see into, either from the path or the bridge.
I couldn't hear the Cetti's Warbler today. Nor could I find the Scaup, but when I went for the second time to the reed bed where he has been seen recently there was an unruly mob of Mallard drakes jostling around on the path. Two of them were wrestling.
When female Mallards are nesting and the males have nothing to do, they get very badly behaved.
The two Mute Swans on the Long Water were exploring a very poor nest site between the Italian Garden and the dead willow tree.
They have been almost everywhere except for the island which has been built for their convenience, which remains settled by Mallards and surrounded by Shovellers.
The Grey Herons' nests on the Serpentine island have been unoccupied for three days. I think these birds have given up, for the third year running.
A Great Crested Grebe was looking very ornamental at the east end of the Serpentine.
The people laying turf on the Parade Ground had come south again, so there were no Redwings where I heard them yesterday. There was only a lone female Pied Wagtail, sprinting around on the grass with a high-legged stride to avoid tripping over the blades.
A small flock of Goldfinches was visiting the feeder at Kensington Palace.
The male Little Owl remains in his hole in the chestnut tree near the leaf yard. Occasionally he looks over the parapet for a few seconds.
The male Tawny Owl came out late again today. I didn't see him till 4.30.
