The first butterfly of spring was a male Brimstone at the leaf yard ...
... and a dandelion flower had come out behind the railings at the Triangle.
The Fieldfare was still on the Parade Ground, in a tree.
It flew down to join three Redwings ...
... looking for worms.
The Little Owls at the Round Pond were having trouble with a pair of squirrels that have invaded their hole, as happened last year. They can leave by an upper hole if their usual exit is blocked, but it wasn't till mid-afternoon that the female appeared in a horse chestnut tree.
A Long-Tailed Tit at the leaf yard was pulling little bits of lichen off a tree.
When I went past later on the way to find the owl, the same bird or its mate was in the same place. It had just got a clump of moss and was about to fly off with it.
A Starling at the Round Pond shone in the sunlight.
The usual small birds were waiting in the Rose Garden, including this Blue Tit in a tree.
A Robin at the southwest corner of the bridge is also a regular customer.
The three Grey Heron chicks could be seen in the nest at the east end of the island ...
... and so could the two older ones in the upper nest.
Pigeon Eater was on the Dell restaurant roof gazing down majestically on his territory.
A pair of Great Crested Grebes were looking their best at Fisherman's Keep.
Coots mated on the nest in the planter in the Italian Garden fountain. The female was at first reluctant to respond to the male's squeaks, but relented.
The Egyptian Geese at the Round Pond have managed to keep all their nine goslings so far. It's a slightly safer place than the main lake, as there are fewer Herring Gulls.
The Black Swan flew to the Round Pond in the morning but returned to the Serpentine early in the afternoon, where it was hanging around with a pair of Mute Swans. I do wish we could find a friend for this restless and lonely bird.
