Priorslee Lake, Woodhouse Lane and The Flash

11.0°C > 12.0°C: Another unremittingly grey morning with occasional light drizzle. Almost calm. Very good visibility.

Sunrise: 06:36 BST

* = a photo today.

Priorslee Lake: 05:05 – 07:25 // 08:10 – 09:18

(188th visit of the year)

Bird notes:

- One of the Mute Swan cygnets wears blue Darvic ring 7JUE. Three of them are unringed. The fifth bird remained in the water and I could not check.

- No more easy counting of Great Crested Grebes. The families are no longer staying 'on territory' and are mixing with each other and the 'spare' adults. Two of the spares were half-heartedly displaying as were the adults in one of the family groups – and in front of their child before the watershed. As a result not too much should be read in to my lower recorded total.

- 116 Lesser Black-backed Gulls flew SE between 06:19 and 06:30, the first four having a good look at the lake before moving off. Then 33 of them decided to settle for a few minutes before they too moved on. Later birds arrived or passed over moving East – West and stopping only briefly (as did the two immature Herring Gulls). Finally at c.09:00 a party of 20 came from the South and settled on the water, again only momentarily.

- 5 Grey Wagtails were on the dam together – probably my highest-ever count. This species is difficult to age / sex at this date but I think three at least were immatures.

- 16 Meadow Pipits flew W in a single group – a strange direction for Autumn passage. Two singles later.

- At 06:40 I heard calls over Teece Drive that I thought would prove to be House Martins very high up. The 'high up' bit was correct, but the sounds came from five finch-type birds. I could not place the calls.

Birds noted flying over / near here:

- 82 Greylag Geese (all outbound in three groups)
- 55 Canada Geese (54 outbound in seven groups; singleton inbound)

- 36 Wood Pigeons
- 18 Meadow Pipits
- 5 finch sp. (see notes)

Hirundines etc. logged:

- >22 House Martins

Count of warblers logged (singing birds in brackets):

Counts from the lake area:

- 2 + 5 Mute Swans
- 13 (9♂) Mallard
- 3 Cormorants: arrived separately
- 1 Grey Heron
- 12 + 6 (5 broods) Great Crested Grebes
- 7 adult and juvenile Moorhens
- 85 adult and juvenile Coots
- 11 Black-headed Gulls only
- 66 Lesser Black-backed Gulls: many immatures
- 2 Herring Gulls: immatures

Birds on the football and academy playing fields c.06:25:

[Wood Pigeons and Magpies excluded]

- 148 Black-headed Gulls on the academy playing field.
- 1 Lesser Black-backed Gull also on the academy playing field.

On / around the street lights etc. pre-sunrise:

Moth:

- *Green Carpet (Colostygia pectinataria): moth species #96 here in 2020.

Other things:

- *>20 Common Wasps (Paravespula vulgaris): all but one at the same lamp.
- 2 very different-looking plumed midges
- *1 unidentified spider

Insects etc. noted later:

- Common Wasps (Paravespula vulgaris)
- Mystacides longicornis caddis flies dancing over the water's edge vegetation

Mammals

- 2 Pipistrelle-type bats only
where are all the Noctule-type bats that were a daily occurrence in April / May?
- 1 Grey Squirrel

New flowering plant species recorded:

None

Believe it or not this is a Green Carpet moth (Colostygia pectinataria). It is not very green – the colour quickly fades after emergence. Neither does the photo show the feathered antennae that gives it the scientific name 'pectinataria' = comb-like. That may be because it is a female and has simple antennae. It may be because it is a bad photo. I last recorded this species in the Priorslee Avenue tunnel on 14th September 2014.

I run the gauntlet of this street light every morning. Just what are these Common Wasps (Paravespula vulgaris) doing? There are at least 19 visible here. I re-examined the lamp at c.09:00 and apart from one wasp asleep on the pole there was no activity at all.

This is a much better photo of a species of spider I failed to identify a few days ago. Guess what? I have still failed. There are rather few spiders with very obvious hairy legs in the photo galleries I use on the web. These have not assisted at all. An attractive species in its own way!

Woodhouse Lane area: 07:25 – 08:10

(14th visit)

Not a full walk up and down: mainly a check of the fields from the roadway.

Count of warblers logged (singing birds in brackets):

- 5 (2) Chiffchaffs again

Other sightings:

- 2 Jays
- 14 Meadow Pipits at least: hard to know whether the same birds were repeatedly moving.
- 1 Linnet over
- 3 Yellowhammers

The Flash: 09:22 – 10:11

(172nd visit of the year)

Bird notes:

- A Song Thrush flushed in to vegetation. My first here since 21st July after which the local birds stopped singing.

Birds noted flying over / near The Flash:

- 1 Meadow Pipit

Hirundines etc. logged:

- 8 House Martins

Count of warblers logged (singing birds in brackets):

- 6 (3) Chiffchaffs

Counts from the water:

- 3 + 7 (1 brood) Mute Swans
- 26 Greylag Geese
- 40 Canada Geese
- 27 (14♂) Mallard
- 45 (11♂) Tufted Duck
- 3 Great Crested Grebes again
- 6 adult and juvenile Moorhens
- 71 adult and juvenile Coots
- 8 Black-headed Gulls

On different lamp poles:

- 5 Common Wasps (Paravespula vulgaris)
- 1 Common Rough Woodlouse (Porcellio scaber)
- 1 Dicranopalpus ramosus-type harvestman

Also noted

- *Mystacides longicornis caddis flies
- 3 Grey Squirrels

When the Mystacides longicornis caddis flies are dancing over the water's edge vegetation it is difficult to identify them. As Autumn approaches spiders are setting webs to entrap them. Here are several. The banded wings and long antennae are diagnostic. Just a few of the many hundreds both here and at the lake this morning.
