The Canada gosling on the Long Water was sitting on its stepmother's back. This is something that cygnets do, but not goslings as far as I know. This little bird is going to be very confused as it grows up.
Its unsuspected sibling was a mile away at the far end of the Serpentine, eating grass under the solicitous eyes of its parents.
The Black Swan was with his girlfriend in an invisible place on the Long Water, and I only saw them as I was going home, when they emerged and cruised under the bridge.
A pair of Great Crested Grebes made a brief excursion ashore on the south side of the Serpentine. They are really not at home on the land.
The Coots nesting in the middle of the Long Water have managed to make quite an imposing structure, considering that it is anchored to a submerged branch by a couple of thin twigs. They were lining it with grass.
But I still think that it will come adrift and break up the next time there is a strong wind.
The Reed Warbler in the reed bed near the bridge was also very hard to see, as Reed Warblers usually are, but he was singing fit to bust and eventually there was a brief glimpse of him through the reed stems.
There was also a Reed Warbler singing at the north end of the Long Water, plus the usual one in the reeds near the Diana fountain.
There are a lot of young Pied Wagtails. Yesterday David Element took this fine picture of two with their father on the edge of the Round Pond.
And this is one of two that were running along the edge of the Serpentine, already hunting for their own insects. It decided to have a rest, and was not worried about being photographed.
Last year's young Grey Wagtail was hunting from the netting over the reed bed north of the bridge.
A Robin was collecting insects and grubs for its nestlings near the Lido.
The male Little Owl came out on his favourite branch of the chestnut tree when the morning rain stopped.
He perched in the classic Athenian tetradrachm pose.
