The Mute Swans in the reed bed near the Diana fountain have two eggs. She seems to be laying at two-day intervals.
The female is sitting on the eggs, so presumably they have started developing. But she may lay six or seven, and their development has to be synchronised. Chicks inside eggs in the later stages of growth are aware of their surroundings, and can hear the others shifting around and tapping on the shell, and signals pass between them about when it's time to come out.
The swans on the Long Water had been mating, and reared up against each other in an affectionate display.
Mallards have a much rougher time, and here is a female assailed by three drakes. Thanks to Virginia for this fine picture.
The Egyptian goslings at the Lido were enjoying a clump of Nowruz plants -- this looks like cress.
One of the little Egyptians at the Round Pond was lounging casually. You can see that the backs of its legs are a bit grazed by sitting on the gravelly tarmac, so it's more comfortable in this position.
Blondie's family were all present, but straggled about and refused to pose nicely for a picture. They will have to try harder if they want fame.
The white Mallard was introducing his mate to the fountain in the Rose Garden. I don't think she has visited it before.
It's hard to see the attraction of this little pool, but it may have something to do with it being lunchtime for humans, and they were soliciting for sandwich crumbs.
A Mandarin drake perched on a branch near the bridge. At various times there were two males and a female on this branch, and there is probably a nest in the tree.
A pair of Coots were starting a nest in a clump of plants in the Italian Garden.
One of the Moorhens in the rafts at the east end of the Serpentine was having a brisk wash.
The pigeon-killing Lesser Black-Backed Gull was practising his snatching skills by grabbing bits of bread off the water without touching down. All the other gulls were just sitting in the water to eat, but evidently he felt the need to keep in training.
A Long-Tailed Tit was pulling spider webs off a lime tree beside the Vista.
A Wren stood proudly on a tree near the bridge. There is a colony of Wrens here, and three were visible.
This is the male Robin of a pair on the east side of the Long Water. He took the food I gave him to his mate, and then came out for more for himself.
A Blue Tit also came out to be fed.
The male Little Owl in the chestnut tree near the leaf yard looked out of his hole for a few seconds.
