Priorslee Lake

16.0°C > 14.0°C: Mainly cloudy. A few spots of rain c.06:15. Spell of heavy drizzle after 08:40. Moderate WSW wind veered N in drizzle. Very good visibility until drizzle, then moderate.

Sunrise: 06:35 BST

* = a photo today.

The heavy drizzle sent me home early. Of course it did not last, the remnant of a weak cold front that dropped the temperature.

Priorslee Lake: 05:08 – 09:04

(187th visit of the year)

Bird notes:

- Still unable able to read any of the Mute Swan cygnets rings. A stray adult arrived and seemed unnoticed for some while as it paddled towards the residents resting on the slipway. Eventually chased away by both adults with the cygnets paddling in hot pursuit. No flying lessons seen over the last few days.

- Just 12 Lesser Black-backed Gulls flew SE between 06:10 and 06:40. After 07:15 I counted 149 birds flying from the E with 124 settling on the lake with at least 25 passing over. As yesterday a few moved on quickly while many stayed to be joined by more from the S. A significant proportion of these (over one third) were immatures, and mostly 2020 birds. A significant departure took place when the battling Mute Swans threatened. A good number stayed though.

- House Martin(s) heard from the estate area at c.06:50 but all I could find was a Hobby cruising around. Just four over the lake in the drizzle.

Repelling the invader. The resident cob Mute Swan in full pursuit mode.

Still chasing. The pen and the five cygnets paddling to catch up. (An adult Lesser Black-backed Gull in the foreground).

"Go damn you"

It finally gets the message. Seemed to be unringed.

Two dreadful shots of a Common Buzzard, I think carrying prey rather than with something caught up in its legs or talons.

From this angle there seems to be a long leg from prey dangling with perhaps a large feather attached to the other leg of the prey?

Just as the heavy drizzle started I flushed this moth which promptly went to the darkest recess of the wooded area on the north side. I felt a flash photo might make it fly so a dull light shot is all I managed. It is a Dusky Thorn (Ennomos fuscantaria). Only my second record here – previously on 22nd August 2018. The larval food plant of this moth is Ash. Like all thorn moths it usually rests with wings partially open. Moth species #95 for me here this year. Will I make 100? There are two 'Autumn' species almost guaranteed but I need a few more.

This is a Common European Earwig (Forficula auricularia). I suppose they have to eat but I thought they were vegetarian – they used to play havoc with my father's Dahlias. The very curved cerci (claspers) show a tooth on the flat basal part confirming this is a male.

I always wonder who wins here. There always seem to be orb-web spiders around but they must be less numerous than the social wasps, so I assume not too many spider get stung. The spider is what I think is Larinioides sclopetarius.

Another one of the same species of spider. Seems to have its legs full of things to eat.
