It's hard to see what's happening in the Grey Herons' nest on the south side of the island, because you have to view it from across the lake. But there are unmistakably two chicks on the left side of the nest. Their parent is lying down on the right side, barely visible.

The Great Crested Grebe pair on the Serpentine that I videoed yesterday were still constantly displaying near the island.

Joan Chatterley sent a fine picture of a Little Grebe on the lake in St James's Park, where there are always a few though their numbers have fallen during the past few years.

Here we only see them at long intervals, and I don't know whether we have permanent residents skulking under the bushes or whether they fly in from time to time and soon leave.

The Coots nesting in the reeds on the Long Water have moved their prized yellow football nearer the nest.

The Coot at Peter Pan titivated its nest, which swayed gently in the waves as it is balanced on a submerged chain attached to the post. It's quite a feat of building but in an incredibly silly place, as a hungry Herring Gull on top of the post can grab a chick whenever it wants.

Two male Mute Swans tried to face each other down. Eventually one of them cracked and allowed himself to be chased away.

The Egyptian Geese at the Lido have managed to hang on to their last two young for another day.

But they keep wandering off and have to be called back by their mother.

The Mandarin pair were back at the Vista.

The male Little Owl near the Henry Moore sculpture was in an awkward place partly hidden by a branch. You can't move left for a better view because there are twigs in the way.

A Carrion Crow was making a nest on Buck Hill.

A Magpie perched in a magnolia and refused to get into the same shot as a flower. Instead it gave me a challenging stare.

A Chaffinch at the bridge was also wondering what was going on ...

... but a Blue Tit knew it would be fed and waited patiently.

A Monk Parakeet was being taken out in a cage to get a bit of sun. I'm sure it isn't kept in that cage at home, because it could untie that loop on the door in seconds.

The fountains in the Italian Garden have been turned off, a small part of the collapse of the western world. But at least it gives you a clear view of the carp in the pool. They weren't deliberately introduced, and probably arrived as eggs stuck the the legs of birds.

A courtship display by Great Crested Grebes ended not in the usual dance waving weed at each other, but in a 'cat display' where one bird flew off a short way and spread itself out to look as big as possible.  This may be just a display of being large and imposing, or it may be a mime of a parent carrying a lot of chicks on its back.

The Coots were fighting again next to one of the small boathouses.

A Cormorant preened on a post near the bridge.

A visit to the Round Pond to check on the Black Swan ...

... found the water inlet turned on, and as usual a Mute Swan enjoying the spray.

Swans are particularly fond of young willow leaves. The trees end up with their overhanging twigs neatly trimmed in a horizontal line at the height of a swan's reach.

The male swan of the Long Water pair, unable to build a nest on the ruined swan island, was making one in the reed bed nest to the Italian Garden. This is a desperately dangerous place, and a few years ago, before the island was made, his previous mate was killed there by a fox. I have asked repeatedly for the island to be repaired, but in vain.

The Egyptian Geese at the Lido are now down to two goslings.

The pigeon-eating Lesser Black-Backed Gull was scanning the shore for his next victim.

The injured Grey Heron in the Dell now seems to be able to put a little weight on its left foot. We shall have to keep watching to be sure.

A bunch of Wood Pigeons feeding on a bit of birdseed jostled each other about and bounced some smaller Feral Pigeons out of the way.

A Wren sang on the corkscrew hazel bush in the Flower Walk.

A Robin stared suspiciously from a tree in front of the greenhouses.

But nothing can stare like a Little Owl. Again, this is the male in the lime tree near the Henry Moore sculpture.

There were sounds from the island of a Grey Heron chick clattering its bill begging to be fed, and I when I got to the other side of the lake so I could get a distant view, there was a brief view of a little head with a punk hairdo. It's on the left side of the nest.

From a still picture I took at the same time it seems that there may be two chicks, but it's hard to tell at this distance and angle.

The Egyptian goslings at the Lido are down from seven to three, and the reason is plain to see -- a pair of Lesser Black-Backed Gulls doing their best to eat them. By the way, these gulls are not the notorious pigeon-killing pair.

On the other hand, this second-year Lesser Black-Back was standing in the pigeon killers' territory unchallenged, and may be their offspring from last year.

A dozing Great Crested Grebe woke and languidly stretched a leg and a wing before going back to sleep.

The Coots on the Serpentine were busy chasing each other ...

... and occasionally a fight broke out.

When I went past later, the row had subsided and a Coot was bringing an unfeasibly large stick to a nest in an impossible place on the edge of the lake.

A Moorhen stood in the dry bowl of the Italian Garden which, like Britain, has been switched off.

A Green Woodpecker climbed a tree beside the Long Water looking for insects in the bark, and gave its distinctive call that sounds like scornful laughter.

The Robin singing in the olive tree at the Lido was out of sight, so I turned the camera on some Herring Gulls soaring over the lake, gaining height for a long glide to a distant place.

The male Little Owl near the Henry Moore sculpture was in his usual place, ignoring the warm sunshine available on the other side of the branch.

There was no action at the completed Long-Tailed Tits' nest in the Rose Garden, but here is a still picture of the wonderful structure.

The nest at the Lido also seems to be complete.

This black bee was on a flower at the back of the Lido. I thought at first that it was an old-fashioned English black Honeybee, but after looking at the picture I think it's a Mourning Bee, Melecta albifrons, a parasitic bee that occupies the nests of Hairy-Footed Flower Bees.

The new Egyptian goslings at the Lido keep wandering away from their parents and have to be called back by their mother.

A pair of Coots have built a large nest on the remains of the swan island on the Long Water.

The swans are vaguely trying to do the same thing, but without a chance of success.

The male Coot chased the female wanting to mate with her, but she didn't fancy the idea.

This is a general view of the swan nest beside one of the small boathouses. You can see why the railings offer little protection from foxes.

A fox dozed on the edge of the Long Water.

The pigeon-killing Lesser Black-Backed Gull found a bit of chicken which he was happy to share with his mate, but not with a bunch of Carrion Crows trying to grab it.

The male Little Owl near the Henry Moore sculpture enjoyed the sunshine.

A Chiffchaff perched in the brambles beside the Long Water.

A Rose-Ringed Parakeet ate pussy willow catkins.

A Coal Tit examined a horse chestnut leaf bud, looking for insect larvae.

A Goldcrest landed in a tree on the edge of the Rose Garden.

In the garden, a female Blackbird was building a nest in a clump of bushes.

A male sang on a twig. They start singing later than the other songbirds, but their song is worth waiting for.

Also in the garden, a Buff-Tailed Bumblebee gathered pollen on a gorse bush ...

... a Hairy-Footed Flower Bee rested on a leaf ...

... and a Peacock butterfly sunned itself in a flower bed.

Paul has been photographing the mice that live in the Tube stations. They are quite bold and will come out on to the platform when things are quiet.

A pair of Egyptian Geese have just brought out seven goslings at the Lido.

A pair of Mute Swans have built a nest behind the railings of one of the small boathouses. Unfortunately these railings are no barrier to foxes, which can simply wade around them.

The Black Swans in St James's Park have enough trouble with the Mute Swans, which have killed several of their cygnets. But that doesn't stop them from fighting among themselves. Thanks to Joan Chatterley for this video.

It's very hard to tell what's going on in the Grey Herons' nest on the south side of the island. It's still occupied, and the heron keeps getting up and poking around in the nest, but I haven't seen any sign of a chick. Nor have I heard one begging in the last few days.

The Long-Tailed Tits in the Rose Garden have really finished building their nest, and only occasionally arrive with a feather for the lining. It's time for the female to lay her eggs.

But this may be the last video I put up of the nest. The government are panicking more and more about the Chinese flu and they are threatening to close the parks.

If so, I shall do everything I can to keep this blog going, though it will inevitably take a different form.

A Great Spotted Woodpecker had to contend with the invasive Rose-Ringed Parakeets that constantly throng the feeder. A Chaffinch managed to get a quick visit.

Another Great Spotted Woodpecker climbed a tree beside the Long Water, but I only managed to get a very distant shot of it.

However, Mark Williams got a close view of a Chaffinch near the bridge.

There was also another Long-Tailed Tit here, preening on a holly twig.

A Song Thrush sang briefly near the Italian Garden, and Elizabeth spotted it in another holly tree. By the time I got to it, it had stopped singing, so here is a still picture of it.

A Wren perched among leaf buds on the other side of the garden.

A Wood Pigeon ate some new leaves.

The very shy Coal Tit appeared in the leaf yard, and after several attempts I managed to tempt it down to take a pine nut from the railings.

In spite of the chilly wind, the sunshine brought the male Little Owl to the front of his hole in the lime tree near the Henry Moore sculpture.
