There is a Kingfisher on the Long Water again -- if indeed it ever left. I saw it very briefly on the Long Water last week, and today I was there with Tom when it sped down the lake, and he managed to snatch a distant shot of it.

Another day, and the Tufted duckling is still on the Serpentine. It spends a remarkably long time submerged, more than a Great Crested Grebe could at this age. But, unlike a grebe, it isn't being fed, and has to find its own food.

The grebe family from the island were at the east end of the lake again, unchallenged by the pair who normally regard this as their territory. Having chicks gives them an advantage in a territorial dispute.

The Black Swan was not having things his own way. The dominant Mute Swans from the Long Water had come out under the bridge as far as the landing stage, and the male chased him and his cygnet some distance beyond there.

I say 'him' and 'his', but there is now serious doubt as to whether the Black Swan is male, despite typically aggressive behaviour. A reader has seen this swan being mounted by a Mute Swan, but I have seen exactly the opposite. We shall have to wait for certain proof.

A shamefully irresponsible dog owner allowed  her greyhound to chase the Long Water swans for some distance. (She is out of shot in this picture.)

This behaviour is typical of a sadly large number of dog owners, who live in the delusion that everything their pet does is amusing, and that the park regulations don't apply to them. They can turn quite nasty, even violent, if confronted. However, this goes beyond mere regulations. Allowing a dog to harass wildlife is a criminal offence under the Wildlife and Countryside Act 1981, and if the owner is apprehended she will face arrest, prosecution in court and a fine of several hundred pounds. The male swan of this pair was attacked and seriously injured by a dog earlier this year, and has only just completely recovered.

Our notorious Lesser Black-Backed Gull has not read the Act, and continues to kill pigeons daily. Recently he has left his usual corner near the Dell restaurant and has been hunting all round the Serpentine, maybe looking for places where the pigeons are less wary.

The Moorhens nesting in the drain near the bridge have had another brood, their third this year and there is still one survivor of each of the earlier ones. They were on the far side of the reed bed, but there were indistinct glimpses of three chicks.

The Mistle Thrushes on Buck Hill were hunting in the grass and eating rowan berries from the trees nest to the West Carriage Drive.

Both the Little owlets near the Albert Memorial were visible in different trees.

The Little Owls near the leaf yard couldn't be found. Plaintive cries from the top of their tree turned out to be from a young Stock Dove begging and flapping its wings.

A Speckled Wood butterfly perched on a leaf near Peter Pan.

Two days ago I saw a black and white moth in a tree near the Physical Energy statue. It was in deep shade and I only got a very bad picture of it. As usual, I didn't know what it was. But I was talking to Tom and one of his friends, and they identified it as a Jersey Tiger Moth. Tom supplied a much better picture of one.
