A tree near the bridge had on it at the same time a Treecreeper preening ...
... a Goldcrest probing a hole for insects ...
... and a Wren taking a momentary rest during its hunting.
The Green Woodpecker was in exactly the same place on Buck Hill, and still calm about being photographed, though it gave me a sharp look over its shoulder.
A Wood Pigeon was drinking in the little pool at the top of the waterfall in the Dell.
The Black Swan was back with girlfriend number one. He seems to have settled down with her, and really we can stop calling her 'number one', because her sister has been finally dumped.
Just up the shore of the Serpentine, a pair of Greylags were displaying. They will have to find a very secluded nest site to escape the park keepers, who are trying to keep their numbers down by pricking their eggs.
The Great Crested Grebes' nest on the end of the raft gets washed away every time there is more than a gentle wind. But they are still attached to this site, and in fact it would do as a nest without any additions.
Possibly, when the time is ripe for breeding properly, which for grebes on this lake is midsummer, they will manage to raise young here. The fence will have some effect in keeping away swooping gulls. They would do much better inside the netting around the nearby reed bed, but as far as I know only one pair of grebes has ever had this simple idea.
This Common Gull is less than a year old, but is beginning to grow grey adult feathers on its back.
A brief sunny spell brought one of the Little Owls out of the hole in the oak tree near the Albert Memorial.
But by the time I got round the lake to the lime tree near the Henry Moore, gloom had set in again.
