A pair of Blue Tits are nesting in one of the lamp posts behind the Lido swimming area, as usual.

Only some of the gas lamps are suitable for nests: the ones with a bulge in the top of the cast iron lamp standard, which gives birds just enough room. Only Blue Tits nest in these places, because the gap between the gas pipe and the hole is too narrow for a Great Tit. However, some lamp posts have access holes lower down which a Great Tit can get through, and I am keeping an eye on a lamp on the path across the top of the Dell, numbered 88, where a pair usually nest.

Under the willow tree near the bridge, a Coot is still persevering with its strangely sited nest. But the twigs keep falling off the stump, and even a Coot's persistence will fail eventually.

The female Mute Swan on the island in the Serpentine was turning her eggs. I could see four, but there may be more.

The swans' obsessive habit of destroying all the plants around their nests has led to part of the island subsiding into the water. There is enough left to support the nest, but the island will need building up when they have finished with it.

The Black Swan and his girlfriend were in the same place as yesterday, beside the Bluebird Boats building.

They are next to the place where food for the waterfowl is sold, and are also in view of the queue to buy ice cream, so it's an excellent place to tout for food.

A Gadwall was feeding on the edge of the Serpentine.

The sunlight showed off the fine purple iridescence on the head of a Tufted Duck at Peter Pan.

Two Mandarin drakes were resting on the edge of the pool in front of the Rima relief. Possibly they have mates nesting in nearby trees.

It would be interesting to see if ducklings are brought down to this pond. It is very small but it is also overgrown with nutritious duckweed, and would keep a family going for some time.

A Great Spotted Woodpecker was pecking at the park of an oak tree next to the leaf yard. Its eyes are half closed, and you can see the extra-strong eyelids that keep its eyes from popping out when it is pecking. Woodpeckers also have a shock absorber inside their skull to avoid brain damage.

A female Blackcap was flying around a hawthorn tree near Peter Pan.

The Little Owl in the lime tree near the Henry Moore sculpture was the only one I saw today.

The one in the oak tree was out at times, but I missed him despite three visits.

These medium-sized mushrooms were growing between the bridge and Rima. I thought they were St George's mushrooms (Calocybe gambosa), but checking on the web shows that the gills are wrong for this species -- they are subdecurrent, running a short way down the stem, rather than adnate, meeting it at right angles, as in a St George's mushroom.
