Priorslee Lake and The Flash

6.0°C > 8.0°C: Dry at the very start, and clear skies to the very far E. Rain from 05:50 – 07:00. Thereafter occasional drizzle from low cloud. An almost calm start with moderate SSE wind later. Very good visibility early, then mainly moderate.

Sunrise: 06:58 GMT

* = a photo today.

Priorslee Lake: 05:30 – 09:06

(232nd visit of the year)

Bird notes:
- Another visiting Mute Swan. It took a lot of chasing by the residents to get it to leave.
- Two Grey Herons disputing the lake c.06:15. Thereafter just one until c.08:50 when another (a 3rd? the 2nd returned?) arrived and was chased away.
- 125 Lesser Black-backed Gulls arrived from the Hortonwood roost between 06:28 and 06:45.
- 41 more Lesser Black-backed Gulls arrived from the E after 08:20. Two first-winter Herring Gulls with them. Rather more Lesser Black-backed Gulls noted flying over – I logged 17.
- Despite a very different passage I again logged almost exactly 400 Jackdaws. The only large group was c.120 at 06:40. Many smaller groups passed until well after 07:00.
- Just a single Starling was noted leaving the NW area. Visibility was not good at the time but I would have thought I would have heard the wings of any big roost departure from the area. About five minutes later c.45 left the N / NE reeds and headed away NE.

Birds noted flying over / near here:
- 2 Canada Geese: duo outbound

- 2 Pied Wagtails

Birds seen leaving roosts around the lake:

Playing fields:
Not visited

On / around the street lights etc. pre-sunrise:
- 2 November Moth-types (Epirrita sp.): on the same lamp pole.
- *1 leafhopper, possibly a Macropsis sp.
- *1 small unidentified bug.
- 1 Paroligolophus agrestis harvestman

Noted later:
- 1 Grey Squirrel

Another day, another visiting Mute Swan to chase away.

Three of the teenagers join in on the action.

Courtesy of the camera we can read its blue Darvic ring – 7JSH.

Just coming to rest. Note the rather pale bill suggesting this is an immature bird.

"leaving so soon?". Oh! I did that comment yesterday.

The tiny insect way at the top of a lamp pole looks like a planthopper. From what I can see on the web the relative breadth of it and the red eye suggests it might be one of the Macropsis species. Then again... Too far away to see enough detail. And it has an even smaller friend at the bottom of the picture. That looks to be a Mirid bug species – there are plenty of very small bugs with long antennae. All those I can find seem to have legs about the same length as the antennae which this does not seem to have. Pass

The Flash: 09:10 – 10:06

Bird notes:
- It was the Moorhens' turn to hide and give me a low count this morning.
- At least 20 Blackbirds with three Redwings and a Jay finishing off the haws (hawthorn berries) at the top of squirrel alley.
- At least 10 Blackbirds at the bottom of squirrel alley, though some of these may have been birds from the top end moving ahead of several dog-walkers (and me).
- After a few days' absence a Grey Wagtail was on the roofs again.
