The Mute Swans on the Long Water have six cygnets, and were taking them out for their first expedition.
But there was no sign of the Canada gosling that was with them.
Blondie the Egyptian Goose, who is now two years old, has had her first family -- there are seven of them.
Unfortunately she is all too prone to those lapses of attention that affect Egyptians. When her mate attacked another bird that had got too close to the family, she went over and joined in, leaving her young unprotected.
The Bar-Headed Goose was on the Serpentine for the second day running. It had been preening, and flapped its very large wings, needed for a bird that breaks altitude records.
The white Mallard was next to it, and copied it.
The Mandarin couple still have one duckling, and were at the bridge with it. The young bird is still not large enough to be out of danger from gulls.
The Great Crested Grebes at the island also only have one chick, as far as I could see. This is probably a good thing, as the supply of small fish is very limited, and its parents will have to work hard to find enough food for even one.
And there is only one chick in the Grey Herons' nest, if you can call this great gawky infant a chick.
The Black Swan is back with his girlfriend, after several days' solitude. They were near Bluebird Boats, and came over to be given digestive biscuits.
The number of House Martins at the Kuwaiti embassy remains steady at a little over 20. I think there are eight nests in the holes in the cornice. This plaster flower, in the middle of the row, seems to have two nests on opposite sides, to judge by the number of birds going in and out.
A Song Thrush was singing near the bridge.
The male Little Owl was at the top of his chestnut tree, in an awkward place for a photograph.
