This dramatic picture by Ahmet Amerikali captures a Jay as it takes a peanut from my hand.
The bird's wings and tail are spread to provide the maximum area so that it can float down as slowly as possible, on the brink of stalling but still under perfect control for this precise manoeuvre. They seldom miss.
The Ring-Necked Parakeets also come down for peanuts, but they are less elegant flyers and have to perch for a moment to take the nut. Here one tries to steal another's prize.
The young Grey Wagtail was flying all over the Serpentine. First I saw it on the roof of one of the small boathouses.
Then it was washing itself on the shore by the Lido ...
... after which it dried itself on the railings.
After yesterday's picture of a Black-Headed Gull enjoying a paddle in fast-flowing water, here is one of a Herring Gull doing exactly the same in the shallows of the Diana fountain.
The Tawny Owl spent the day in his usual place on top of the nest tree.
Some Magpies arrived and yelled at him, but he didn't even bother to open his eyes.
As the sun set, a Carrion Crow admired its reflection in a puddle on the Parade Ground.
Crows and various gulls are profiting from the snacks dropped by visitors to the funfair, and there is always a good crowd of them waiting around the enclosure.
