The Robin pair in the Rose Garden were together in a bush, with the female begging her mate to feed her. She will need him to do this when she's nesting. I gave him a pine nut, but the pair retreated into the back of the bush and I didn't get a picture of the exchange.
The male Blackbird was singing strongly, well hidden in a holly tree. He has to raise his voice as the Rose Garden is a noisy place, with competition from police sirens and helicopters, billionaires' sons roaring around in Ferraris from the showroom in Knightsbridge, and loud dreary rap from the Bluetooth speakers of the skaters in the Serpentine Road.
The Blackbird from the Dell was out on the lawn, hopping around in the grass looking for insects and worms.
The Green Woodpecker on Buck Hill called from a tree, as usual hard to see among the twigs but I finally got a picture of it preening.
While going round the tree for a clear shot I found a single Long-Tailed Tit ...
... and a Jay.
The wind had dropped, and the female Little Owl at the Round Pond was out in the horse chestnut tree.
The third brood of Grey Heron chicks on the island were frantically begging their parent to feed them.
One of the second brood was down on the shore of the island ...
... and the other two were back in the nest.
The young heron from last year was on the edge of the Dell stream, picking up a stick. The nesting instinct seems to set in early.
The pair of Mandarins cruised across the Vista ...
... and there was a single drake by the boathouses. You can see that the pattern of white stripes on his side is different.
A few minutes later I saw a pair near the island, but I'm pretty sure it was the first pair which had flown over from the Long Water.
The odd couple of the Gadwall drake and female Mallard were side by side in the Italian Garden. The spare Mallard drake was hanging around out of shot. He doesn't have much of a time, but the female has made her choice and there's nothing he can do about it.
The last Egyptian gosling on the Serpentine has made it through another day.
The male by the Henry Moore sculpture was sitting in the shade while his mate was nesting in a tree -- I haven't found where this is, as the dead tree they used in the past is now decayed and they have abandoned it.
The Coots nesting on the Mute Swans' island in the Long Water were fussing around together on the edge. They are never molested by the belligerent swans, maybe because these have learnt that an angry Coot is a nuisance even if not a threat.
A male Hairy-Footed Flower Bee was making the most of the fading wallflowers in the Rose Garden.
