For the past couple of days there has been a fair number of Swifts over the Serpentine, after several months' absence.
I think they are a flock beginning to move south before they migrate to Africa for the winter. Our resident House Martins will be going the same way soon.
The Great Crested Grebe family with three chicks are still keeping close to the same moored boat, a good safe place as the overhanging hull protects them from swooping gulls and they can dash back into cover behind the boat at a moment's notice.
It is a strain being a grebe parent, and sometimes you just have to stand up and have a flap.
However, the long-running saga of the single Coot chick at Peter Pan has had a sad end. It hasn't been seen for a few days, and today there was a Grey Heron standing on the empty nest.
The Common Tern is still on the Long Water.
This very ordinary picture of a family of Egyptian Geese is notable for what it does not show.
All the young Egyptians on the Serpentine have grown up without suffering from 'angel wing'. This may be partly attributable to the fact that they are now such a common feature of the park that people are no longer stuffing them with bread, which is thought to cause the nutritional deficiency that distorts growing wings.
The Little Owl was out on his usual branch during a sunny interval in this very changeable day.
