Two of the three latest young Grey Herons had come down from their nest for the first time. They stood uncomfortably on the wire baskets around the edge of the island.
The third was still in the nest.
A few minutes later one of the young herons had flown back up to the nest and the other was amusing itself by climbing in a clump of purple loosestrife.
They aren't independent yet and will be returning to the nest to be fed. Presumably this is the end of the very long nesting season, which started on 21 December last year and has produced 17 young birds from six nests, a record for the park.
Old nests remain useful. The Coots south of Peter Pan have long since finished bringing up their family, but both adults and young use the nest as a resting place.
Even the perennially unsuccessful nest on the post, which has now lost most of its twigs, still provides a useful perch.
The dominant Mute Swan continues his advance down the Serpentine. He had brought his teenagers beyond the Lido ...
... and was bullying another swan just for the hell of it.
An Egyptian Goose displayed its iridescent green secondary feathers.
One of the young Blackbirds behind the Queen's Temple was foraging under a lime tree.
A Great Spotted Woodpecker flew into the top of a tall lime by the leaf yard.
The older of the two familiar male Chaffinches in Kensington Gardens intercepted me by the Serpentine Gallery, again in a lime, and flew out several times to catch pine nuts in midair.
A threadbare Jay waited for a peanut in a dead tree by Peter Pan.
A visit to the clump of hemp agrimony in the Dell found a tiny Buff-Tailed Bumblebee, smaller than an ordinary Honeybee. They vary quite a lot in size.
There were also a handsome Batman Hoverfly ...
... a Common Drone Fly ...
... and a Greenbottle.
A Willow Emerald Damselfly pereched on the railings. Oddly, that's the best place to find one, as they like the warmth of the iron on a sunny day.
Tom was at Rainham Marshes and sent a fine but sad picture of a Reed Warbler feeding an enormous young Cuckoo that has been wished on the nest by its parasitic parents. Much as I love birds, I can't help finding Cuckoos horrible.
