(177th visit of the year)

An abbreviated visit ahead of other commitments for the day.

Best bird today was a Little Egret that I flushed off the North Shore. It was not present earlier and I had not seen it arrive.

Bird notes:
- I assume that with the bright super blue moon last evening the geese were able to spend the night feeding in the fields and this is why I did not see any flying outbound.
- Just an adult Great Crested Grebe was seen and no begging juvenile was heard. I forgot to mention yesterday that the adult and the begging juvenile were seen early. Later there was a brief skirmish after which one bird was seen in flight while an adult was noted on the water. I could positively age the flying bird: my impression was of an adult. A begging juvenile was heard only later. This was not in the area occupied by the adult.

Beetles:

The clear skies rapidly disappearing to the East as the red dawn suggests that rain is on the way.

Another 'winner'! A record shot of the Little Egret flying off!

Another Snout moth (Hypena proboscidalis). This is from the second brood which is smaller and more strongly-marked that the brood that flies in May and June. I assume this is due to the difference in food plants utilised by the caterpillars.

My first Square-spot Rustic moth (Xestia xanthographa) of the year. The second commonest macro moth currently flying according to the West Midlands Moths web site here. [Snout is rated the 30th]

A Grouse Wing caddis fly (Mystacides longicornis) in the sailing club shelter.

Also a first for me here this year: a Walnut Orb Weaver spider (Nuctenea umbratica) also in the sailing club shelter.
