There is a family of Reed Warblers in the small patch of reeds near the bridge. This is slightly surprising, as earlier this year a gang of Mute Swans broke down the fence and destroyed a lot of the reeds, but these have grown back well.

There are also sounds of young Reed Warblers from the reed bed at the east end of the Serpentine, and I think at least one pair in the bed near the Diana fountain have young.

A band of Long-Tailed Tits went through the horse chestnut trees behind the Lido. The horse chestnut trees in the park have been badly affected by leaf miner moth, and you can see the damage to the leaves caused by the caterpillars. But this is an opportunity for insect-eating birds.

On a hot afternoon, a group of Feral Pigeons cooled off by splashing around in the Serpentine.

A Wood Pigeon was eating unripe elderberries on the island. Both Wood Pigeons and Rose-Ringed Parakeets seem to like fruit when it's very unripe, sour and hard.

But Carrion Crows prefer their food soggy. Even this pappy bit of sliced bread gets dipped in the lake.

Another pair of crows were having a conversation on the fence around the field maple tree near the leaf yard.

I couldn't find the Little Owl here today.

Near the Diana fountain landing stage, a young Grey Heron was flapping frantically, trying to dislodge a bit of plastic netting wrapped round its bill. I was just ringing Hugh Smith, the new Wildlife Officer, when the heron managed to get the netting off and all was well.

Not long ago, a heron got a piece of netting tightly wrapped round its bill and nearly starved to death before the people at Bluebird Boats managed to catch it in a landing net and remove the netting. I've shown this video on my blog before, but there's no harm in seeing it again.

The two young herons who are clearly siblings and go around together were on the gravel bank in the Long Water.

The Tufted Duck with five ducklings was letting them wander all over the place. Although they have grown noticeably, they are still not safe from being seized by Herring Gulls, and only their ability to dive fast has kept five alive so far.

But the one with six ducklings kept a motherly eye on them.

The Great Crested Grebes with three chicks had moved up the Serpentine and come into conflict with the neighbouring pair. Although they can win these confrontations by the moral force of having chicks, they decided to back off for the sake of a quiet life, and went back under the bridge. There are lots of fish here too.

The pair with two chicks were in their usual place under the trees on the east side of the Long Water.

All was peaceful on the nest at the east end of the island.

I can't see the nest at the west end. It was started in a place where you could see it through the wire baskets, but this is a place where Cormorants like to stand, so the grebes moved along to a safer spot. I know there's a nest there because I've seen grebes carrying twigs to it by diving under the baskets.

A teenage Moorhen preened on a chain at Peter Pan.

A young couple were having a picnic in the small electric boat, chauffeured around the lake by Mateusz. They had an impressive hamper and a bottle of rosé wine in an ice bucket and I thought, How romantic.

Unfortunately it turned out to be a photo shoot advertising something.
