Two young Reed Warblers were occasionally visible in the reed bed next to the bridge, as their parents whizzed back and forth bringing them insects from surrounding trees.

But they were keeping in cover because one of the young Grey Herons was staring down at them from the top of an oak tree.

The young Grey Wagtail was by itself at the east end of the Serpentine, looking for insects in the fuzzy 'geotextile' that the reed rafts are made of, and which has been exposed by the Mute Swans ripping out the plants.

There are two young Blackbirds in the Dell. This one is already finding its own worms.

There are also two young Robins. I don't know whether this is the one I photographed yesterday or the other one, Anyway, they are too charming to ignore.

The young Great Tits are still demanding food from their parents. This one near the leaf yard was getting very impatient.

Someone has been feeding this young Magpie that hangs around the path near the bridge. Every time I pass it comes out and looks at me expectantly.

The teenage Mandarin has turned out to be male. Its bill is already turning red.

I wonder what this peculiar white streaked Mallard drake looks like when he isn't fading into eclipse.

The Black Swan was at the Diana fountain landing stage with his girlfriend. At the moment she is clearly recognisable by a patch of dark feathers on the front of her head.

The Little owlets near the Albert Memorial were calling but wouldn't come into view. However, their father was visible on a horse chestnut branch.

The Little Owl family near the leaf yard were inaudible and invisible when I went past first, but a return visit showed the male on his favourite branch in the nest tree.
