On a frosty morning the male Tawny Owl was fluffed up to the maximum against the chilly breeze blowing past his exposed position in the nest tree.
The ponds in the Italian Garden had partly frozen, and a first-year Black-Headed Gull was experiencing ice for the first time.
One of the seven young Mute Swans was on the same pond.
It had taken refuge there because its father was charging around the Long Water chasing his offspring away. He has definitely decided that it is chucking-out time, a most unwelcome surprise for these pampered young birds.
There was a very confused Black-Headed Gull in full summer breeding plumage on the Serpentine.
At the east end of the lake there was a brief glimpse of the young Grey Wagtail, which I have not seen for some time.
The place is thronged with people going to the funfair, and I only got time for one hasty picture before it sped away to somewhere quieter.
A single Redwing was under the rowan tree on Buck Hill, still finding a few fallen berries that were not completely rotten.
A chattering noise from across the road showed that it had companions in a tree.
A flock of Long-Tailed Tits was moving along the path at the top of the hill, joined by a few Blue Tits.
A small tree behind the Rima relief is constantly full of Wood Pigeons flapping heavily about, clinging to twigs and occasionally losing their hold and falling out.
The attraction seems to be ivy berries. The birds have finished the earlier and more palatable fruit.
