A very quiet call near the bridge drew attention to a Treecreeper.
You can't go out looking for these shy little birds. They just happen in unexpected places.
A flock of Long-Tailed Tits can be heard coming from some distance away. This one was in a small olive tree next to the Lido restaurant.
The tree belongs to a Robin, and when I went past an hour later its owner was singing.
There were Mistle Thrushes looking for worms in the grass on Buck Hill.
Beside the Serpentine a Pied Wagtail was also hunting, taking no notice of the Christmas crowds bustling along the pavement.
A Great Crested Grebe was fishing beside the outflow of the Serpentine, where you can get a good view of underwater activity from the balustrade at the edge of the path.
A little group of Red-Crested Pochards at the Serpentine island added colour to a grey drizzly day.
The Black Swan, whom I had missed yesterday, was at the east end of the Serpentine. His girlfriend was nearby, but they wouldn't pose together so here he is by himself.
The speckled hybrid goose was at the Lido having a quiet moment of reflection.
In midwinter the Egyptian Geese fly around from one dead tree to another, displaying to each other and calling noisily. They nest in hollow trees, so it makes sense for them to investigate sites, and to establish their claim to one in good time.
