A Blue Tit in a tree in the Rose Garden sang quietly to his mate on the next branch. They aren't in full song yet.

A Robin sang in a rose bush. Of course they have been singing all winter.

A Chaffinch was also singing, but I couldn't make a video because of background noise.

This is the shy one of the pair of Coal Tits near the Albert Memorial which won't come to my hand. But it did consent to take a pine nut off the ground.

Sunshine brought out the iridescent colours of a Starling at the Lido.

Carrion Crows were also looking finely glossy.

The usual Jay waited at the bridge for its customary peanut.

A pair of Stock Doves are nesting in the hole in the plane tree north of the Albert Memorial that has previously been used by Mandarins.

The nest at the east end of the island still isn't getting any larger despite the constant attendance of a Grey Heron.

A Peregrine flew out from the tower.

Someone told me that he had seen the man with the Harris Hawks flying one over this area, hired to scare away Feral Pigeons from nearby flats. You'd hardly think this was necessary with a pair of Peregrines hunting here. But certainly there were far fewer pigeons than usual. Maybe they've become blasé about the Peregrines.

A Herring Gull had taken over the Coots' nest on the boat platform. I'm sure it doesn't mean to nest there, and it's too young anyway, so it had moved in just for the fun of driving out a Coot.

The Coot under the willow near the bridge was firmly occupying its nest ...

... while a pair of Great Crested Grebes hung around waiting for an opportunity to steal it. This picture was taken from the bridge, looking down through the tree.

The dominant Mute Swan at the west end of the Serpentine was busking around bullying the other swans. The breeze ruffled his feathers.

The artificial island in the Long Water made for swans to nest on had fallen to bits after the destructive birds had ripped out the reeds that held the surface together. Now it's being repaired with tons of gravel, which should be sufficiently swanproof.

A pair of Mute Swans displayed and mated at the Lido.

Another pair were courting nearby ...

And as usual, the Black Swan was obsessively following a Mute Swan around.

A pair of Greylag Geese ate dry reeds.

The pigeon-eating Lesser Black-Backed Gull and his mate were together in their favourite place on the Dell restaurant roof.

Two were nattering at each other on the posts at Peter Pan. As so often with gulls, it's hard to tell whether they were courting or quarrelling.

The Black-Headed Gulls are gradually getting their black heads (which in fact are dark brown). The single Common Gull at the right still has the dark-streaked head of its winter plumage.

The Grey Heron on the nest with the chick (not heard recently, I hope it's OK) broke off a twig.

The Peregrines were on the tower with their backs to the drizzle.

A pair of Blue Tits chased each other around in a treetop.

The pair of Coal Tits at the Albert Memorial were in a holly bush. One came to my hand to take a pine nut.

A Long-Tailed Tit arrived at the osmanthus bush in the Rose Garden where I thought the pair were starting a nest. Sure enough, it was carrying a bit of lichen. It only stopped on this rose stem for an instant, and here is the best shot I could get.

A Wren chattered on a twig near the Henry Moore sculpture.

Yesterday Sergey Anpilov saw a Stonechat on Buck Hill, and managed to get a picture of it with a pair of binoculars and his phone -- not an easy thing to do.

I couldn't find it today. It might have crossed the road to the Meadow, where there is a larger area of scrub that Stonechats like. But the drizzle was turning to rain, and I gave up and went home.

Tom was at Harrow Lodge Park, where he got a fine picture of a Water Rail catching a worm.

 A pair of Long-Tailed Tits are beginning to make a nest in an osmanthus bush in the Rose Garden. This is probably the pair that nested in the broom bush last year, only a few yards away. One of the birds paused on a rose stem before flying into the bush, which is too dense for anything to be seen.

A pair of Coal Tits visited the feeders in the Dell ...

... where the resident pair of Mallards rested on a rock in the stream.

Most of the birds are feeling the approach of spring and pairing up. Two Feral Pigeons shared a post at Peter Pan.

Magpies perched together in a tree.

Even the disorderly mob of Carrion Crows seems to be sorting itself into pairs.

Two Moorhens climbed in the collapsed willow by the bridge, where they make a nest every year in a hole that can't be seen from the bank.

A pair of Coots enjoyed a shower.

The Peregrines on the tower stayed at an unsocial distance, but even they were looking at each other and calling.

Only the Robins are still staying apart, but it won't be long before they give in to the call of spring.

Seven Grey Heron nests on the island were occupied today, though not all of them will progress to breeding. The right nest in this video is the one that has a chick in it, though I still haven't got a proper picture of it. One other nest, not seen here, has a heron sitting on eggs.

The old and incompetent pair of Egyptian Geese, notorious for never having managed to raise a single gosling in 21 years, were on an urn in the Italian Garden.

A Buff-Tailed Bumblebee browsed in a clump of snowdrops.

Purple crocuses are out beside the Long Water.

Going home from the park by way of the garden in Rutland Gate, I heard a Dunnock singing quietly on a bush.

A Chaffinch sang in a tree in the Rose Garden.

There was also a Blackbird looking for worms, with an unexpected musical accompaniment from some rollerbladers in the Serpentine Road.

The first Greenfinches this year: a pair dimly seen in a yew tree beside the path north of Peter Pan.

A Long-Tailed Tit waited to visit the feeder in the Dell.

The female Peregrine was on the tower briefly several times ...

... often flying out and circling over Hyde Park.

A Grey Heron looked down at the chick in the nest. I still haven't got a clear sight of it.

A young Herring Gull dived into the Long Water, but all it came up with was a bit of plastic bag.

A Black-Headed Gull looked down apprehensively at two Moorhens, wondering if it was going to get knocked off the post. But the Moorhens were too busy washing and preening to bother with it.

The whole of last year's family of Moorhens were together in a planter in the Italian Garden.

A Coot and a Black-Headed Gull were at cross purposes at Peter Pan, the Coot trying to build a nest and the gull pulling it to pieces to find insects.

A pair of Great Crested Grebes hung around the Coots' nest under the willow near the bridge, hoping for a chance to steal a nest much better than they could build themselves. This trick does sometimes work, but needs constant vigilance to keep the Coots from taking the nest back.

A little fleet of Tufted drakes followed a solitary female, then started diving..

News of more broods of Egyptian Geese: Joan Chatterley found five goslings in St James's Park ...

... and James Norton found five in Ravenscourt Park.

No sign of any here yet,

You have to look carefully to see anything in this video, but the new Grey Heron chick is just beginning to put its head above the edge of the nest.

A Cormorant showed off the different colours of its feathers on a post.

With Egyptian Geese, the different wing colours make a surprising contrast.

The lonely Black Swan was still closely pursuing a Mute Swan.

The Mute Swans were feeling the onset of spring, and courting ...

... and chasing each other.

A Pochard drake at the Vista had a dirty face from dabbling in the mud.

Two Gadwall drakes and a female cruised around in one of the Italian Garden fountain pools.

A Coot was starting to build a nest in a hopeless place on the edge of the Dell restaurant terrace. When I passed a second time it had already given up.

One of the reasons why the Coots' nest on the post at Peter Pan keeps disappearing is that a Black-Headed Gull picks it to pieces looking for insects.

A Black-Headed Gull had won a large piece of bread and was having difficulty swallowing it. It could have gone under a bench and pecked it into smaller bits, but it's in the nature of gulls to gulp down everything at once before another gull steals it.

The female Peregrine perched on the tower for a few minutes before flying away.

A Goldcrest appeared unexpectedly out of a bramble patch near the Vista, a place where I've never seen or hear one before.

The Blue Tit near the Italian Garden came out several times to ask for a pine nut.

The Chaffinches in the park suffer sadly from scaly growths on their feet, caused by a viral papilloma. It doesn't kill them, but it makes them quite lame. Young birds seem unaffected but I think they all get it eventually.
