Today's best sighting was of a Kingfisher on the Long Water by the Italian Garden. It's a male, as you can tell from its all-black bill -- females have an orange lower mandible. These occasional visitors are usually seen here only in winter.
Pigeon Eater, in his usual spot by the Dell restaurant, consumed as much of his latest victim as he wanted and left the remains for a Carrion Crow which had been watching from a safe distance. The difference in styles is very obvious. The gull doesn't use his feet to hold the pigeon down, and has to drag it around awkwardly. The crow just plants a strong foot on it and can rip pieces off with ease. Probably Pigeon Eater could use his foot, which is by no means weak, but the idea simply hasn't occurred to him.Maybe he should watch a crow at work.
The Grey Heron at the island that has been seen lying down on one of the wire baskets at the island can stand up, and in fact I saw it flying in. Its behaviour had been a bit worrying, but it seems to be absolutely OK.
Great Crested Grebes have been hanging around the collapsed willow next to the bridge, but they show absolutely no sign of wanting to nest.
Nor do the ones on the Serpentine. It would be a sad year without a sight of their stripy chicks. But there is still time, as they usually start late.
Two of the Red-Crested Pochard drakes were also under the bridge. There hasn't been a female here at any time this year. These aren't migrants; they fly in from the other London parks more or less at random. Some years ago a pair nested near Peter Pan and successfully raised to young, the only time as far as I know that they have ever bred in the park.
The newest Coot chicks in the Italian Garden are down from six to four, and surprisingly the older family on the pool seem to have lost one of the eight. It looks as if they've been fighting.
The undersized Mandarin duckling on the Round Pond may be the runt of the brood, but it attracted cries of admiration from a watching child.
The Mallard family sprawled on the edge.
A Mute Swan with pink feet rather than black is known as a 'Polish' swan. 'Polish' cygnets are white rather than the normal grey. The gene for this mutation is recessive and sex-linked, so that usually only females have the 'Polish' appearance, and males with the gene are normal-looking. Only if a male swan gets the gene from both parents will he have pink feet. The name dates from the early 19th century when swans were still eaten, and swans were imported from the Baltic region to increase stocks. Some of these were found to have the mutation.
This swan on the Round Pond is regrowing her flight feathers after moulting, and you can see the emerging primaries.
A Greylag Goose on the Serpentine, one of the regular visitors that come to moult in June, has an unusual amount of white on its face, and several times has been misreported as a White-Fronted Goose.
Four pictures taken by Ahmet Amerikali at Rainham Marshes show the difficulty of identifying birds that don't look like their picture in the book. This is a Whitethroat, but its throat isn't particularly white. I think from its vague soft markings that it's a young one.
This Whitethroat has much bolder markings, but the yellow edges of its bill seem to show that it too is a young bird.
This is clearly a female Linnet, lacking the pink front of the male.
But this one has unusually strong markings on its back for a Linnet. There are finches with stronger markings than Linnets, such as Redpolls, but they all have smaller bills so I think this has to be a Linnet. However, I may be wrong about any or all of these.
Another slightly uncertain identification: a Black-Tailed Skimmer dragonfly on the railings in the Dell. I think this is a female that has lost its early yellow and black markings and gone a dull colour.
Anyway, there is no doubt about this male Emperor dragonfly in a fine shot by Ahmet.
There are lots of Comma butterflies all round the park. This one was in the Dell.
The spiky flowers in the eryngium patch near the Lido were crowded with Honeybees and Buff-Tailed Bumblebees.
