Who can resist a singing Robin?

A Robin sang on top of the big clump of climbing roses in the Rose Garden. (I know I film Robins singing very often, but who can resist that lovely song?)

This is the Robin near the Henry Moore sculpture that will come and take food from your hand.

A short way along the path by the Steiner bench, one of the local pair of Magpies perched on a stump in front of a flowering gorse bush.

A white Feral Pigeon presided over a gathering on the Huntress fountain. Although the fountain is turned off in winter, rainwater collects in the bowl and it provides a place for them to drink and bathe.

There were plenty of Common Gulls on the posts at Peter Pan. The big gull in the middle, a very pale Lesser Black-Back with pinkish legs, may be a hybrid with a Herring Gull.

A Grey Heron fishing in the cut reeds below the Diana memorial fountain caught two carp in less than a minute.

The heron with the red bill was standing on the nest at the west end of the island where it nested unsuccessfully last year. But its mate is now missing, presumed dead, and it must look for a new one. A visit to Regent's Park, where there are plenty of herons, would probably find one.

The heron from the nesting pair also has a reddish bill but with more yellow at the tip.

Another heron, maybe the unattached one that often stands on the edge of the island, was trying to pull a twig off a tree.

A heron's bill is fine for stabbing fish but doesn't have much bite, so herons find this quite difficult. Gathering twigs is normal behaviour for this time of year and doesn't necessarily mean that it has a mate or is about to nest.

The Great Crested Grebes from the west end of the island were cheekily displaying at the other end, in front of the resident female who is the mother of the youngest grebe.

A Moorhen stood on the lower bowl of the marble fountain in the Italian Garden, getting heavily splashed.

It's a parent of the four young ones here. These are now beginning to get their adult red and yellow bills and yellow legs, and the next moult will give them the darker plumage of an adult.

A male Mute Swan was hanging around the place where the killer swan and his mate nested last year.

The site in the reeds had been trampled.

However, the killer and his mate were just round the corner of the reed bed, so the intruding swan was risking his life. If the killer pair have any sense they will abandon this place and use the nesting island in the Long Water which is now part of their territory, but they may cling to the old place where -- more by good luck than by good management -- they have avoided foxes and successfully hatched at least two broods.

A pair of Egyptian Geese were noisily claiming territory on a dead tree near the Speke obelisk.

Blondie was among a big crowd of geese and swans being fed at the Dell restaurant. There was no sign of a mate. After breeding successfully once she seems to have taken a vow of chastity.

Thirty Pochards, all drakes, rested in a row along the edge of the Long Water. Today Des McKenzie counted 87.

Although Pochard have a terribly skewed sex ratio, about eight males to one female, the situation is not as dire as it seems here because male and female Pochards migrate separately.

I'm afraid the intruding squirrel has definitely taken over the lower part of the Little Owls' nest tree at the Round Pond. The last few times I've seen an owl here it has always been higher up on the diagonal branch. They may have to nest elsewhere. Fortunately they are quite vocal in the breeding season and it should be possible to find them again.
