A Long-Tailed Tit paused for a few seconds on a twig near the Buck Hill shelter. There is a nest here somewhere in the brambles but the young birds haven't emerged yet.
A Starling had seized a bit of bread from someone feeding the geese at the Vista.
Birds can survive having some bread in their diet, though it is mostly empty calories and an unadulterated diet of it is seriously bad for them -- and there have been cases of swans choking after eating large amounts of pappy white bread. Set against this is the fact that most of the Mute Swans on the overcrowded lake are underweight from a lack of healthy natural nutrition, so that feeding them up can be helpful.
A Robin sang on the fence surrounding the noisy construction site at the Serpentine Gallery. This year we are getting two 'pavilions', one of which is a huge structure on massive concrete foundations. The architects commissioned by the gallery seldom have any idea of what a temporary building is, intended only as a usable café lasting a few months, and instead are making the usual cumbersome personal statements.
A fine picture by Ahmet Amerikali of the male Reed Warbler under the Italian Garden. A female has also been visible and there is certainly a nest in here somewhere.
A Pied Wagtail explored the non-slip rubber matting on the Lido jetty. This is full of insects feeding on the Egyptian Goose droppings that lodge in the grooves of the matting, and is much visited by wagtails.
The Little Owl at the Round Pond was in her usual lime tree.
Pigeon Eater is being filmed by a team from the American Public Broadcasting Service for the second year in a row. They tell me that they already have good video of him in action. This is certainly the most famous gull in the world, and he struts and preens as if he knew it.
The three Grey Heron chicks had all climbed out of their nest, and this picture of two of them is from a couple of days ago. We have never had four nests in one season before, at least not in my time. This is a growing heronry, so far unaffected by the Egyptian Goose invasion that is causing the bigger one in Regent's Park to decline.
A heron was fishing by a clump of purple loosestrife in the Italian Garden fountains.
This tough plant which grows well in wet places is spreading through the park after it was deliberately planted in the fountains here in 2011, but on the spot the Coots are chewing it to shreds and it is disappearing. Now that the tubular frames with netting have been removed from around the clumps of irises, the Coots are wrecking these too. Old photographs of the Italian Garden show clumps of plants thriving in the pools, but they were taken before the mistaken decision to introduce Coots into St James's Park in the early 1920s, since when they have quickly colonised Central London at the expense of the mild Moorhens.
A male Great Crested Grebe was fishing by the Triangle. Probably this pair will soon choose a nest site in the trees on the other side of the bridge, where there are several suitable places.
Coots don't need suitable places. There is a new nest on a single projecting branch of the big fallen poplar in the Long Water.
It has become harder and harder to see the Mute Swan nesting in the reeds by the Serpentine outflow, but she has been sitting for a month and should soon have some cygnets. However, these will be just as invisible until she brings them out on to the lake.
Sean Gillespie found a spectacular insect I have never seen in my life, a Lime Hawk Moth. It looks like a tiny Vulcan bomber in its RAF camouflage.
They are named because they like lime trees, not because some of them are lime green. Others shade more towards pink.
A Honeybee in the Rose Garden needed all six legs to climb over a spiky allium flower.
Ahnother was having a much easier time in an orange rose, one of the few double roses here that is open enough for them to get in.
The display of flowers here is now at its best.
A puzzling deposit of dense white fluff on the east side of the Long Water. This is often produced by Black Poplars, but I couldn't see one anywhere near. The local plants in the undergrowth are common bramble, Himalayan Blackberry, bindweed and Snowberry -- which is so named for its white berries, not because it produces white fluff.
