Priorslee Lake [with Woodhouse Lane] and The Flash

Priorslee Lake:  04:10 – 05:40 // 06:35 – 09:05
[Woodhouse Lane:  07:10 – 07:50]
The Flash:  05:45 – 06:30 again

10.0°C > 12.0°C:  Cloudy. Moderate SSW wind. Very good visibility.

Sunrise: 04:48 BST

Two noteworthy sightings today
- At 04:30 a noisy party of at least 80 large gulls flew S to the W of the lake. Most odd.
- In Woodhouse Lane I heard four times and saw on one occasion a Yellow Wagtail. It suggests this species is breeding in the fields near here though I was unable to pin it down. This would be a first for me in this area. It follows one over the lake on 28 May which I thought at the time was a rather late date for a migrant. The following day I thought I heard one fly off the dam ahead of me but as I saw nothing and it seemed unlikely I did not record it. Now however it seems quite probable.

Priorslee Lake:  04:10 – 05:40 // 06:35 – 09:05

(147th visit of the year)

Bird notes from today
- On several days recently I have almost subliminally noted calling Little Grebe, uncertain as to whether to log it. Today I heard the characteristic trill for sure – but from where?
- There was an additional single Great Crested Grebe for a while this morning – as well as the ‘extra’ pair that have been present for several days. At 08:25 I saw a single bird low over the water, climbing away and leaving. Strangely after this time it was the pair that I could no longer find!
- A party of 16 presumably Racing Pigeons flew W. Much later either a lost bird or a local Feral Pigeon followed.
- At least 7 Starlings were collecting food from the football field. I thought the juveniles had all fledged. Are they feeding unusual second broods: or replacement clutches of failed attempts?

Bird totals:

Birds noted flying over or flying near the lake:
- 1 Greylag Goose (inbound)
- 10 Canada Geese (outbound)
- 18 Lesser Black-backed Gulls
- 2 Herring Gulls
- c.80 large gulls (as highlighted)
- 17 Feral / Racing Pigeons
- 3 Wood Pigeons only
- 3 Collared Doves
- 36 Jackdaws
- 22 Rooks

Hirundines etc. noted:
With breezy and overcast conditions many hirundines etc. around most of the time
- >50 Swifts
- >4 Barn Swallows
- >25 House Martins

Warblers noted (singing birds):
- 6 (6) Chiffchaffs
- 15 (13) Blackcaps
- 3 (3) Garden Warblers
- 2 (1) (Common) Whitethroats
- 7 (4) Reed Warblers

Counts from the lake area:
- 2 + 7 (1 brood) Mute Swans
- 10 (8♂) + 2 (1 brood) Mallard
- Little Grebe heard
- 6 + 2 (1 brood) Great Crested Grebes (see notes)
- 1 Moorhen again
- 26 + 22 (8 broods) Coots

Again nothing was on the lamp poles pre-dawn.

Seen later:
- A Fox along the S side at 04:25 was my first here this year.
- Appropriately I noted my first Foxglove flowers (Digitalis purpurea). From the size of the spike I must have overlooked this for some days.

It was a very cloudy morning with the odd early break, one of which produced this glimpse of a ‘red sky in the morning’.

This flying Great Crested Grebe perhaps shows off the unexpected pattern of the upper wing rather better than the bird I photographed yesterday.

Here we see in rather better detail the distinctive caddis fly Mystacides longicornis. Note that the long antenna are striped and the eyes are red. Unique wing pattern helps too.

This is the Foxglove plant (Digitalis purpurea) that I first noticed this morning. Must surely have overlooked it for some days for it to be this tall. When I was walking Woodhouse Lane I was watching for this plant which is usually common in the verges – “about time” I thought. Did not see any there.

The characteristic bell-like structure of the individual flowers. 

And this is what you would be looking at if you were a bee. In practice it would probably look very different: insects are supposed to see colour very differently from us. How do they know?

Notes from Woodhouse Lane (07:10 – 07:50)

(18th visit of the year)

Notes from here:
- One calling Chiffchaff seen accompanying another that was carrying food.
- Yellow Wagtail(s) as highlighted.
- A family party of Goldfinches with at least three juveniles.
- Also a family party of Linnets with juveniles. It was heartening to see breeding success this declining species.
- The singing Reed Bunting was in the fallow area near the composting centre this morning – a better place to attempt to nest than the crop fields from where I have previously logged it singing.

Totals of ‘interesting’ species (singing birds)
- 1 Great Spotted Woodpecker
- 5 (4) Skylarks
- 2 (2) Chiffchaffs
- 2 (2) Blackcaps
- 2 (2) (Common) Whitethroats
- 2 (2) Song Thrushes again
- 2? Yellow Wagtails
- 2 (2) Chaffinches
- >10 Goldfinches
- >6 Linnets
- 7 (4) Yellowhammers
- 1 (1) Reed Bunting again

The Flash:  05:45 – 06:30

(140th visit of the year)

Notes from here:
- A skein of 22 Canada Geese passed N to the W of the pool without deviating. Even more present here as well.
- It is now almost impossible to separate the Mallard ducklings from the adults and I will no longer attempt to do so. Raising 13 to adult status is a higher number than in most years.
- Where were all the adult Coots hiding?
and
- Another instar Common Green Shieldbug (Palomena prasina) on a lamp-pole.
- A very nondescript and unidentifiable caddis fly sp. on another lamp pole.

Birds noted flying over / near The Flash:
- 22 Canada Geese
- 1 Stock Dove again

Hirundines etc. noted:
- 6 Swifts

Warblers noted (singing birds):
- 1 (1) Chiffchaff
- 3 (2) Blackcaps

Counts from the water:
- 3 + 4 Mute Swans as usual
- 3 Greylag Geese
- 72 Canada Geese
- 40 (>22♂) + ?? (2 broods) Mallard (see notes)
- 9 (5♂) Tufted Ducks
- 1 Great Crested Grebe
- 1 Moorhen only
- 12 + 11 (3 broods) Coots

Unlike the caddis fly at the lake this specimen lacks any features to aid identification. With nearly 200 species on the British list and most requiring, at a minimum, examination of the arrangement of spurs on the legs I think we will leave this as caddis fly sp.

An instar Common Green Shieldbug (Palomena prasina). The red hues indicate it is not an adult. The white areas are from the flash need to illuminate it this gloomy morning.

------------------------------------------------------------------------------------------------------

Between the lake and The Flash:

At or around the lower pool (singing birds):
- 1 (1♂) Mallard flew off
- juvenile Moorhen(s) heard again
- 1 (1) Chiffchaff

Nothing of note at or around the upper pool.
