Still chilly and grey, and not much happening. But the Bearded Tits are still in the reed bed at the Diana fountain to add a touch of class to the proceedings.

They have now been here for over two months -- the first month unobserved, of course, after the first announcement of their sighting went astray. And people are still coming to see these famous little birds.

An inexperienced pair of Great Crested Grebes were trying out their dance moves at the Serpentine island. All went well in the first stages.

But then he dived to get a bit of weed to wave at her, and she didn't budge, so when he came up there was an awkward moment. However, it was passed off with mutual salutes, and they will learn to get the timing right. All the stages of the dance are hard-wired into the bird's brain, but they still have to practice to get them properly synchronised. Like all carnivorous creatures, they have plenty of spare time, and what better way to spend it than in perfecting elaborate rituals?

In contrast, the Bearded Tits have a low-calorie winter diet of reed seeds made even less nutritious by the amount of indigestible fluff around each seed, so they have to eat almost non-stop just to stay alive, and have little time to spare. However, in summer they change to eating aphids, of which there are plenty in the reeds at that time, and this gives them the leisure to nest and breed.

The two young Mute Swans on the Italian Garden pond, which had been quarrelling with each other, have now made up and were peacefully pulling up algae from the same patch.

Perhaps the attack of the adult swan a few days ago has given them a shared enemy to concentrate on. But I wonder how and when they will re-establish a position on the main lake. They may have to settle for the Round Pond, the home of the low-status swans with no claim to territory. It is all a bit feudal.

A female Tufted Duck was doing nothing in particular beside the Serpentine.

They are omnivores, with plenty of nutritious small water animals in their diet, so they can afford to relax.
