The Black Swan, cruising on the Long Water, saw 'his' cygnet on the far side with some other Mute Swans and charged over, displaying a magnificent expanse of ruffles.

He chased off the swans, collected the cygnet, and led it back under the bridge. They sat side by side on the shore.

These are the three Greylag goslings that have been adopted by the Canada pair, with the teenage Canada that is part of the family. One of them definitely has a darker bill and legs than the other two. However, it shows no other sign of being a hybrid, and it's probably just natural variation.

The interestingly coloured hybrid goose hangs out with the Canadas. Since goslings 'imprint' on their mother, this probably means that its mother was a Canada and its father a Greylag. The other way round is more usual.

Three teenage Mallards appeared at the Vista. You can see that their wings are still shorter than those of adult ducks. I haven't seen them before, and think they must have flown in.

There is also a teenage Greylag Goose on the Serpentine which was definitely not hatched on the lake, and must have flown in too.

Blondie's three young are now teenagers too, but are still staying together in a companionable huddle.

The young Great Crested Grebe was resting in front of the island.

I haven't seen its parents recently. Could they be nesting again in the same place on the island? The bushes have now grown so much that it's impossible to see.

Even patient Grey Herons get bored. This one, waiting for a fish under the balustrade of the Italian Garden, yawned and then flew away.

A young Pied Wagtail hunting along the edge of the Round Pond caught an insect.

One of the Little owlets from the nest near the Albert Memorial stared at me narrowly from an oak tree.

A Comma butterfly perched on a leaf near the Long Water.

Breaking the regulations on a gigantic scale: this huge model swimmer is an unwelcome reminder that the park is going to be messed up for weeks by the annual triathlon.
