A pair of Gadwalls turned up on the Serpentine. Here is the male, with his restrained but finely detailed plumage.
Gadwalls are erratic visitors. There is a small permanently resident population which I think is based on the lake in Buckingham Palace Gardens, where they have sometimes bred. This is added to by winter migrants. But all of them seem to wander erractically about the central London parks, and you never know when or where you will see one.
A flock of half a dozen Greenfinches flew over the Italian Garden and landed in a nearby tree. These are residents, but are not numerous in the park, and are hard to see at times when the males are not singing, as they prefer the tops of trees.
Three of the seven young Mute Swans were having a practice flight along the Serpentine. They had to come down at the bridge. Swans will not fly under the arches, although there is plenty of clearance for them, and they have not mastered the adult swans' method of hauling themselves up to an altitude where they pass perilously over the top of the bridge just above the roofs of passing cars.
One of the male Ring-Necked Parakeets is now confident enough to take peanuts from my hand. The females have been doing this for years, but for some reason the males seem to be much more nervous.
The male Tawny Owl had moved round to the 'balcony' on the north side of his nest tree. This is a place where a branch has broken off, leaving a hole that gives access to the hollow inside of the tree, and the owls can climb up to their nest and out of the top of the broken trunk.
The owl was quite at peace when I took this photograph, but a few seconds later two Jays and two Magpies arrived a started screaming at him, also joined by an angry Blackbird.
The male Little Owl was on his usual perch in his nest tree. When I went past again during a sunny interval to try to get a better picture he had gone away, so this grey image will have to do.
