A warm sunny day brought a lot of people into the park, and that's never good for seeing birds. In particular the Little Owls, which ought to have been out enjoying the sunshine, were all staying stubbornly in their holes despite two visits to each of the three places.
But a Robin was singing in a bush in the Rose Garden.
One of the other pair here was waiting in a small hawthorn for its daily treat of pine nuts.
A pair of Blue Tits here are now quite hard to photograph, as they rush out of the tree and flutter around you in their eagerness to be fed.
The Robins at Mount Gate were also insistent.
The familiar male Chaffinch in Kensington Gardens was on the east side of the Long Water, the first time he's found me there.
Another Chaffinch was singing in a tree by the Buck Hill shelter ...
... and there was a male Greenfinch just along the path.
The Grey Heron that hangs around the Kensington Gardens side of the bridge now has a mate, and they were in the top of a variegated holly tree. I only arrived as one flew out, so I didn't get a picture of them together. A few years ago herons built a nest here in the top of a Chinese privet tree, but it never came to anything.
On the other hand, the heronry on the Serpentine island is booming. There's still a sitting bird on the fourth nest. This nest is really too small and will be badly overcrowded if they can produce chicks.
One of the three young herons in the third nest stood up. They are almost fully grown now.
A parent stood in the nest below, craning round to preen the underside of its wing.
This young heron on the island must be from the first nest, as it's quite neat looking -- the three from the second nest are still very shaggy.
Coots have built a nest on the chain at the west end of the island, and decorated it with a horrible old plastic bag.
The dominant Mute Swan on the Long Water may be a ruthless killer but he is also devoted to his mate and will be an attentive father when her eggs hatch.
There is yet another brood of seven Egyptian goslings on the Serpentine. They were by the Triangle.
Nearer the island, the previous brood is now down to five. There are not all that many Herring Gulls on the lake at the moment, so there is a chance for them.
Two butterflies in the Flower Walk, a Red Admiral and a Speckled Wood, managed to cling on to ivy leaves as they were blown about in the wind.
A Honeybee browsed on a ceanothus.
