The crowd of birds eating berries in the yew tree near Peter Pan was joined by a Mistle Thrush. The berries are beginning to run out, except on the side of the tree facing the path, which is too exposed for the birds' comfort when people are passing. But a wet day with no people will see that corrected.

In contrast, the heavily berried rowan trees on Buck Hill were deserted except for a Carrion Crow.

One of these trees has far more berries than the others in the group, but the birds have been visiting it less. Perhaps there is some difference of flavour or ripeness.

A pair of Nuthatches came down to take pine nuts off the fence of the leaf yard.

A large flock of Long-Tailed Tits passed along the side of the Long Water near Peter Pan.

Below them, some Moorhens were having a fight, in which as many as four joined at one time, as well as a Coot. Moorhens and Coots fight in the same way, leaning back and kicking their opponents, and then jumping on to them.

The male Little Owl was out on his usual branch enjoying the warm sunshine.

The male Tawny Owl also came out on his favourite spot on the broken trunk of the nest tree. The flies that had been plaguing him seemed to have gone away.

But no sooner had he settled down than he was harassed by half a dozen Magpies. One of them actually flew over to attack him directly, and the owl quickly retreated into his hole. Here the aggressive Magpie shouts down at him.

It is probably not a good idea to go so close to an angry owl, and I was surprised when the owl retreated, as it could easily have slashed the magpie with its powerful talons.

The male Tawny Owl is still troubled by flies, and was restless on his perch on top of the nest tree. Here he has a good shake ...

... and a scratch to get rid of them.

There are still a lot of insects around, evidently because of the mild weather. The area around the Italian Garden is full of ladybirds, most of them the proper red kind rather than the invading harelequin ladybirds. They used to have a nest in the public convenience behind the Italian Garden, but this was destroyed in the redecoration of the place, so they must have found somewhere else.

The Little Owl was in the chestnut tree next to his nest tree, and there were no flies on him. As an insect-eating bird, he regards them as a snack rather than a pest.

This is a young Wood Piegon eating holly berries. It has not yet developed the white neck ring of an adult, but it does have the typical white wing bars. This one's eyes are mid brown, changing between juvenile dark brown and the rather odd pale grey of an adult. It is easy to mistake a young Wood Pigeon for a Stock Dove until it spreads its wings.

There were two Song Thrushes feeding in the yew bush north of Peter Pan, probably the pair that nests in the leaf yard just the other side of the statue. This one is the female, though I only know this because her mate was singing quietly to himself in the middle of an adjacent holly tree. The birds don't spend long in the yew: they dive in, grab a few berries, and go to perch in another tree.

There was a Blackbird in the yew with a white patch on her neck which made her look rather like a Ring Ouzel. This beautiful picture was taken by Eleanor Cogger.

A few months ago Andy Sunters saw what he thought might have been a Ring Ouzel between the Diana fountain and the bridge, though no one was able to find it again. It might have been the same bird.

The eight young Egyptian Geese at the Round Pond were still in good order, resting on the edge in the warm sunshine.

Several of the plane trees on the path between the Physical Enerby statue and the Speke obelisk are heavily infested with fungus. They are quite old trees and perhaps no longer in the best of health. I think this fungus is Pholiota squarrosa again, though it is less yellow than the one I photographed a few days ago near the Serpentine bridge.

The yew bush to the north of Peter Pan was full of activity, with several Blackbirds and Ring-Necked Parakeets eating its berries, and Blue and Great Tits hopping around looking for insects. These were joined by a Goldcrest.

Goldcrests like yews, which give these tiny birds cover in all seasons, but I had never seen one in this bush before.

Next to the yew, in a hawthorn, a Song Thrush was waiting until things quietened down so that it could have a go at the berries.

The loud rattles of Mistle Thrushes around the beech tree next to the Tawny Owl's nest tree showed that an owl was in sight.

You can see the difference in the patterns of the spots of Song Thrushes and Mistle Thrushes. Song Thrushes' spots have pointed tops and cluster in rows along the bird's body. Mistle Thrushes' spots are more oval and wider, and are arranged in a more transverse way. This is more reliable than distinguishing the species by size or colour, which you can never be quite certain of, especially in poor light.

The Tawny Owl himself was taking no notice of this chorus of disapproval.

Both Little Owls were on view. The female was near the male's usual perch in the nest tree ...

... and the male was in the adjacent chestnut, mostly obscured by leaves blowing about so I was lucky to get this hasty shot.

There was a different Pied Wagtail on the roof of the small boathouse. This is a first-winter bird, with a grey back and light greyish marks on its face. An adult female would be similar with a white face, and an adult male would be almost entirely black and white.

Recently I claimed that Honey Fungus (Armillaria mellea) was growing in fairy rings in the park and was challenged by Mario, who said that the park's fairy rings consisted of the true Fairy Ring Mushroom (Marasmius oreades). Since then I have been looking for a Honey Fungus ring and have not found one, as all the rings of any variety had been smashed by mowing. But today I found a ring of a different fungus near the Serpentine Gallery.

However, I don't know what it is -- maybe a Lactarius species? It was growing between a horse chestnut and a recently cut down lime tree.

There was also this violet-tinged mushroom in the middle of Buck Hill.

It might be a Field Blewit (Clitocybe saeva, formerly Lepista saeva). However, its thin stem makes it look quite like a Fool's Funnel (Clitocybe rivulosa), a mushroom so poisonous that you shouldn't even touch it, let alone eat it.

There are at least six Jackdaws in the park, so it seems that they must have bred successfully after their arrival earlier this year. Two of them were near the Tawny Owls' tree, and the other four were in the Diana fountain enclosure picking up grubs and worms in the grass. Here one of them has found an insect larva.

Another welcome return: the Black-Headed Gull with the ring number EY09813 has arrived back on the Long Water. It was perched on its favourite post at the Vista, and flew over straight to me and caught pieces of biscuit thrown up in the air.

This bird was ringed as an adult by Roy Sanderson on 18 January 2012, and has come to Kensington Gardens every winter since.

The Egyptian Geese at the Round still have their eight young. They were on the edge of the water and weekend visitors were giving them bread, which is very bad for them and can cause the growing birds to develop 'angel wing'. The pond has notices telling people not to do this, but they are too small and it is really a lost cause.

Two Great Crested Grebes were fishing over the wire baskets near the Serpentine bridge. They caught several medium-sized perch. Here one of them shoots past the other under water.

A single Mistle Thrush was perched in a rowan tree on Buck Hill. It showed no inclination to pick the berries. Maybe it had already had a lot, and was full.

A flock of Long-Tailed Tits and other tits flew past Peter Pan. When a Long-Tailed Tit looks straight at you its face looks almost like that of a tiny owl, because of its very frontally set eyes.

These must help them in their headlong flight through the twigs, though the birds are so tiny that they can't have much depth perception. Even Little Owls, much larger than tits, have to bob their heads from side to side to get a good impression of depth.

The male Little Owl was in the chestnut tree next to his nest tree.

The male Tawny Owl was in the beech tree next to his own nest tree for most of the day, but moved to the top of the nest tree in the middle of the afternoon.

An immature male Shoveller was standing on the edge of one of the Italian Garden ponds, looking miserable. It allowed me to come quite close, which is not normal behaviour for these shy birds. Closer inspection showed that it had a wound on its upper chest, and another one on at the bottom of the nape of its neck. I am pretty certain that it had been seized by a Peregrine, and had managed to struggle free from its talons.

When I came past an hour later it was still in the same place, as dejected as ever. But it was a very lucky duck, and I hope it soon recovers from its fright and its injuries.

This duck is the Mallard that we mistakenly thought was an adopted Tufted duckling because it was dark chocolate brown. It is still in the same place, at the far east end of the Serpentine, and has grown into a dark but normally marked female (or at least, if it were male, I think it would have shown signs of a yellow bill by now).

The two Jackdaws are still on the north side of the Serpentine. A couple of days ago I saw them from a distance over this spot, playing in the strong wind. They are certainly two of the Jackdaws from Kensington Gardens, because they took pieces of digestive biscuit without hesitation.

A Blackbird was eating berries in the yew bush between Peter Pan and the Italian Garden.

A Song Thrush arrived on the branch behind it, and surprisingly chased the larger bird out before returning and diving into the middle of the bush.

The male Little Owl was in the chestnut tree next to his nest tree, perched on one of his favourite branches.

The male Tawny Owl was not visible but it was quite clear where he was, because two Magpies were looking down at his nest site in the hollow tree and yelling at him. This one is standing right on the edge of the hole, which seemed unwise with an angry owl just below.

A pair of Gadwalls turned up on the Serpentine. Here is the male, with his restrained but finely detailed plumage.

Gadwalls are erratic visitors. There is a small permanently resident population which I think is based on the lake in Buckingham Palace Gardens, where they have sometimes bred. This is added to by winter migrants. But all of them seem to wander erractically about the central London parks, and you never know when or where you will see one.

A flock of half a dozen Greenfinches flew over the Italian Garden and landed in a nearby tree. These are residents, but are not numerous in the park, and are hard to see at times when the males are not singing, as they prefer the tops of trees.

Three of the seven young Mute Swans were having a practice flight along the Serpentine. They had to come down at the bridge. Swans will not fly under the arches, although there is plenty of clearance for them, and they have not mastered the adult swans' method of hauling themselves up to an altitude where they pass perilously over the top of the bridge just above the roofs of passing cars.

One of the male Ring-Necked Parakeets is now confident enough to take peanuts from my hand. The females have been doing this for years, but for some reason the males seem to be much more nervous.

The male Tawny Owl had moved round to the 'balcony' on the north side of his nest tree. This is a place where a branch has broken off, leaving a hole that gives access to the hollow inside of the tree, and the owls can climb up to their nest and out of the top of the broken trunk.

The owl was quite at peace when I took this photograph, but a few seconds later two Jays and two Magpies arrived a started screaming at him, also joined by an angry Blackbird.

The male Little Owl was on his usual perch in his nest tree. When I went past again during a sunny interval to try to get a better picture he had gone away, so this grey image will have to do.

There were two Common Gulls on the buoys around the edge of the Lido swimming area. They are not the first to be spotted here this year, since someone else found one a few days ago, but they are the first I have seen.

Common Gulls are usually said to have pale yellow or yellowish-green legs. This one's legs are mid grey, and the other's were a dingy mustard colour.

A plastic sponge was floating on the Long Water, looking like a piece of cake. Several Coots and Black-Headed Gulls pecked pieces out of it, tasted them and spat them out, leaving the way clear for the next bird to try this deceptive object.

One of the young Great Crested Grebes on the Long Water managed a short flight.

Flying does not come easily to these birds, whose small wings demand a very high unstick speed achieved by a long foot-propelled run. But they do manage to fly reasonable distances, always at night so you seldom see one at any altitude.

The Little Grebe on the Round Pond was visited by a model yacht. It took no notice and went on fishing.

The young Grey Wagtail was on the floating reed beds at the east end of the Serpentine, which were blown off their moorings by yesterday's wind, and are jumbled all over the area. The bird is standing on the plastic tube that was used to cover the top of the mesh fence, which has also come adrift.

A Nuthatch came down to take seeds off the fence of the leaf yard.

The male Tawny Owl was in the beech tree next to the nest tree, in the same place as yesterday. You can see this place by standing under the nest tree and looking up through its withered leaves at the beech tree; the owl is only a few feet from the top.

The Little Owl came out on to his usual perch at 1.30, although the day was cold and windy.
