(171st visit of the year)
Bird notes:
- no third Mute Swan today.
- at 05:15 I noted 14 Mallard flying off East; 20 adults and the four juveniles on the water. How these relate to the 51 I counted on the south-west grass and the water at 07:45 is hard to say!
- the Great Crested Grebes were typically problematic, moving around and diving. There seemed to be a fourth pair with two young, some days old, in the more difficult to view south-west area. Also the two now independent juveniles from different broods were spending time together (or close-by).
- a single Swift was briefly over the East end at 05:30. A trio was over the South side for a while c.07:45.

Moths:

It seems a long while since I managed to photograph an almost full moon. This is the just waning Buck Moon, the eighth full moon of 2026. It was full at 15:36 on Wednesday.
The number of butterflies is declining fast. Those that are still flying are looking care-worn as epitomised by this Gatekeeper Pyronia tithonus.
A new moth for the year on a street lamp pole pre-sunrise. It is a Common Grass-moth Agriphila tristella.
"Brothers in Arms?" Two Red-tailed Bumblebees Bombus lapidarius share one of the few extant Knapweed flowers.
Not many hoverflies again today: mostly singletons once more. This Common Dronefly Eristalis tenax has more orange-brown on the abdomen than many. A variable feature on many Eristalis species.
This is a Wasp Plumehorn Volucella inanis, a species where all three bands across the abdomen are yellow...
- 1 !*Common Grass-moth Agriphila tristella [previously Common Grass-veneer]
It is some weeks since I saw my previous Dead-head Hoverfly Myathropa florea.
...more clearly seen here.
A Hornet Hoverfly V. zonaria with the upper band on the abdomen orange rather than yellow.
Close up and personal with a different Hornet Hoverfly.
Probably the same White Crab Spider Misumena vatia I photographed a few days ago.

Very much not a micro-moth was this, my second Red Underwing Catocala nupta of the year, unhelpfully silhouetted against one of the strip lights that, vaguely, illuminate the tunnel.

- a Great Crested Grebe was seen at the top end. Ten minutes later it, or another, was back at the bottom end where I usually see one.
- the Little Egret still here. Also the Grey Heron again.

I do believe this Moorhen has taken over a Coot nest and looks to be brooding eggs or young.
