The Long-Tailed Tits have started building their nests, a long job as the birds are small and the nests are large and complex -- spheres made of spider's webs, moss and feathers. This one has gathered some webs. It will wipe the bundle across the surface of the nest, drawing out the strands to make a strong binding.

A pair of Goldcrests were jumping around in the trees near the bridge. They usually nest here.

A Wren came out of the bushes near the Triangle car park and posed obligingly for the camera.

The Kingfisher was on his favourite branch near the Italian Garden.

The workmen laying turf on the Parade Ground have moved up the hill, and the Redwings have returned. They were on a patch of bare earth under a tree to the west of the bandstand.

The mild weather brought people out on to the terrace of the Lido restaurant, and Starlings were waiting on the fence for some of them to leave so that they could grab their leftovers.

In the lowest of the Grey Herons' nests on the island, one of the birds was sitting, invisible until its mate arrived, when its stood up ...

... and flew off to gather some more twigs for the nest.

Herons take turns to incubate their eggs, so you can't tell which is the male and which the female.

Great Crested Grebes also take turns on the nest. But here is the pair at the island going out fishing together, so it looks as if they haven't started sitting.

One of the Coots in the oddly placed nest on the wire baskets near the bridge glared indignantly at a Cormorant which had come much too close to the nest.

Surprisingly, the incompetent Egyptian Geese at the Henry Moore sculpture still have their last chick. It's unusual for one of their broods to survive for more than two days.

Another pair of Egyptians flew over the Serpentine, displaying their conspicuous white wing patches.

A Mute Swan washing at the Lido seemed to be dancing the cancan.
