Most of the yew trees in the park have Goldcrests in them, and you notice this more now that they are singing their high-pitched song. But they tend to stay deep in the leaves, and usually the most you see is a brief flash of yellow as they move around restlessly looking for insects. This one, in the yew between Peter Pan and the Italian Garden, stayed still for a few seconds.

Johanna van de Woestijne, who is in London again and always visits the park, took this fine picture of the little group of Mallards with the white female landing on the Serpentine.

Her feathers are pure white all over, a disadvantage for a bird as white feathers are soft and fray easily. Many white birds have dark wingtips, which wear better.

The blonde female Mallard on the Serpentine also has pale primaries. Her secondaries, which are dark blue on a normal Mallard, are brown, as you can see on her left wing as she has a vigorous flap after preening.

It was a bad day for geese. Some Canadas had been trying to nest on one of the reed rafts, but something has happened and the eggs are strewn all over the raft.

And this Greylag had got the top of a drinks can stuck on its bill. Of course Malcolm the Wildlife Officer was sent for, and by the time you read this it should be all right.

Someone had dropped a bunch of flowers in the Serpentine. The young Egyptians gave it a cursory glance and decided that it wasn't edible.

Soon afterwards a Feral Pigeon had no scruples and ate several flowers.

The new Little Owl was basking in the sunshine on his usual tree, and stretched a remarkably long wing. They look quite big when they fly.

The usual male Little Owl was out of his hole and also enjoying the sun.
