The Little Grebes were calling from the bushes on the edge of the Long Water, and came out together. They are in their dark chestnut breeding plumage.
A pair of Great Crested Grebes were dancing on the Serpentine. If you know their behaviour you get plenty of time before the dance begins, so here is the moment when they touch as they rear up in the water.
The Black Swan, still with girlfriend number one, was having a faceoff with his old enemy, the big male Mute Swan who regards the area behind the reed rafts as his own.
The Black Swan won this encounter. But maybe that was because it happened outside the line of rafts, not on the Mute Swan's territory.
A Dunnock was singing in a tree near Peter Pan. It is a beautiful song.
And two more Goldcrests were singing at each other near the bridge, a few feet from the place where their nest was last year. Perhaps both were hatched here. It has been a very good year for these tiny birds, and more have survived the winter than usual.
There were eleven Siskins in a tree near the Queen's Temple.
There was also a single singing Greenfinch, but it was too high up for a picture.
The Redwings on the Parade Ground were flying in and out of the small trees to the west of the bandstand.
A Treecreeper appeared again in the shrubbery on the east side of the Long Water.
This place is halfway between the Henry Moore sculpture and the shelter that I flippantly call the martial arts bandstand (which today was occupied by some people doing what seemed to be mindfulness exercises).
A Song Thrush was rooting around in the undergrowth on the other side of Henry Moore.
Despite falling rain, the Little Owl in the oak tree was keeping watch from his hole.
When I passed earlier the pair of Stock Doves were looking into the hole in an interested way, and he must have felt the need to put up a stiff resistance. Stock Doves are attractive birds, but we all hope the owls will win.
