The Reed Warbler family on the Long Water next to the bridge can be seen from the bridge, flying around the water side of their little reed bed. But they are too far away for a good picture, so here is one of the easier family next to the Diana fountain.

The reed bed near the bridge also had a Cinnabar moth (Tyria jacobaeae) in it, though it would not get into a position where you could appreciate its fine markings.

And there are lots of Common Blue damselflies here, of which the males are bright blue ...

... and the females a light greenish beige, which makes them quite hard to see.

There was just one Black-Headed Gull on the Serpentine -- not the first one to return from its breeding grounds to the park, as there were five on the Round Pond a few days ago. It was circling hungrily among the boats ...

... watching the pigeon-eating Lesser Black-Backed Gull ripping up another victim, and was clearly hoping to be able to swoop in for a quick bite.

 A Wood Pigeon was bathing in the little pool at the top of the waterfall in the Dell.

There was a Treecreeper near the Tawny Owls' tree, which I visit daily in the hope that an owl might be visible. None was.

However, the male Little Owl was on his usual branch in the chestnut tree near the leaf yard.
