22 Apr 21

Priorslee Lake, Woodhouse Lane, The Flash, Trench Lock Pool and Trench Middle Pool

1.0°C > 10:0°C: Cloudless with frosty start. Calm early with light SE breeze later. Good visibility.

Sunrise: 05:57 BST

* = a photo today

Despite strong Spring sunshine from cloudless skies it remained surprisingly chilly and very few insects were tempted out.

Priorslee Lake: 04:55 - 06:35 // 07:30 - 09:50

(71st visit of the year)

Bird notes:
- A male Pheasant was on the academy playing fields at first light.
- Both Canada Geese were visible for part of the while. I assume this means the clutch is not complete and so long as the eggs do not get chilled then they do not to be brooded all the while
- A pair of Gadwall was unexpected. This species was scarce this last winter with only one previous record since most birds departed in early January.
- The drake Tufted Duck 'appeared' and then 'disappeared' . Whether it flew in and out or was just lurking in the reeds is hard to say
- Now three singing Reed Warblers.
- Also three Common Whitethroats with two males chasing and singing. The third bird was heard scolding and was likely a female though it was not seen well-enough to confirm.
- A pair of House Sparrows seen in the SW copse where I saw one carrying nesting material last year. I did not confirm breeding there.
- Another late record of an overflying Siskin. I note from the excellent River Dee Estuary site (http://www.deeestuary.co.uk/lsight.htm) that a small movement of this species has been evident there recently.

Birds noted flying over / near here:
- 5 Canada Geese: single and two pairs inbound
- 2 Greylag Geese: pair inbound
- 3 Wood Pigeons only
- 36 Jackdaws
- 1 Rook
- 1 Siskin

Hirundines etc. noted:
- 8+ Sand Martins

Count of warblers noted (the number in brackets is singing birds)
- 2 (2) Willow Warblers again
- 14 (12) Chiffchaffs
- 3 (3) Reed Warblers
- 19 (13) Blackcaps
- 3 (2) Common Whitethroats

Counts from the water:
- 2 Canada Geese
- 2 Mute Swans: pen sitting throughout
- 2 (1♂) Gadwall
- 5 (5♂) Mallard again
- 1(1♂) Tufted Duck
- 7 Moorhens
- 17 Coots only
- 1 Little Grebe: heard only
- 4 Great Crested Grebes

On / around the street lamps pre-dawn
- 3 plumed midges (Chironomus plumosus)
- *1 spider sp., perhaps Clubiona brevipes

Later noted:
- 1 Buff-tailed Bumblebee (Bombus terrestris)
- *2 Tapered Droneflies (Eristalis pertinax)
- *1 Migrant Hoverfly (Eupeodes corollae)
- >10 Alder Flies (Sialis lutaria)

As a postscript to yesterday I forgot to include in the fly-overs three un-aged Black-headed Gulls that flew SE at 05:45.

Clear skies do not make for spectacular sunrises. Calm water and mist rising ahead of a light SSE breeze later. I have often wondered - where does the breeze go at night?

A different perspective.

The pair of Gadwall, the duck on our left with the orange side to her bill.

I was well-pleased with this shot of a singing male Common Whitethroat. Two males were chasing around singing and hardly perched for a second and this grab shot is even in focus. Note the grey head (brownish on females). Both sexes have rusty-brown markings in their wings.

This is another Tapered Dronefly (Eristalis pertinax). I have tried hard to turn it in to something less common as it seemed to be only about two-thirds usual size. Just natural variation.

I will try and do better. This was my safety-shot which is slightly out-of-focus. Immediately afterwards the hoverfly flew off. It is a Migrant Hoverfly (Eupeodes corollae). Rather badly named these days as while we do get migrants from Europe (as we do with many species of hoverfly) this species is known to breed in the UK.

This closely matches photos on the interweb of the spider Clubiona brevipes, though I know that there are many species in the genus. I am taking advice.

Woodhouse Lane: 08:25 - 09:05

(15th visit of the year)

A slightly longer walk down the hill as far as the piles of 'completed' compost left in a field.

Notes:
- no sign of any returning Whitethroats as yet.
- a VERY distant female Wheatear was atop a favoured rock, often used by passage migrants. So, so far away ...
- At least four Linnets in the roadway.

Some numbers (the number in brackets is singing birds):
- 1 Pheasant heard
- 2 (2) Skylarks
- 4 (3) Chiffchaffs
- 1 (0) Blackcap
- 4 Linnets
- 5 (1) Yellowhammers

(Ed Wilson)

Between the lake and The Flash

- One Moorhen on the upper pool.
- 1 (0) Blackcap by the upper pool

After having shuffled around a bit before I photographed it yesterday morning the Herald moth (Scoliopteryx libatrix) has now left the Priorslee Avenue tunnel after its week's residence.

Trench Lock Pool: 10:50 - 11:15

(9th visit of the year)

Bird notes:
- Only noteworthy sighting was a male Reed Bunting. I have always wondered why they are not common here with suitable vegetation along the retaining dam, albeit that this is mostly populated by flocks of House Sparrows. My only previous record here was on 01 April 2017.

Birds noted flying over / near here:
[The local Wood Pigeons and Jackdaws not included]
None

Hirundines etc. noted:
None

Count of warblers noted (the number in brackets is singing birds)
- no Willow Warblers
- 2 (1) Chiffchaff
- 2 (2) Blackcaps again

Counts from the water:
- 5 Canada Geese: two pairs and a single; perhaps a 6th on eggs somewhere?
- 2 Mute Swan: one bird sitting on the nest throughout
- 4 (4♂) Mallard
- 7 (4♂) Tufted Duck
- 3 Moorhens
- 8 Coots
- no Great Crested Grebe

My 2021 bird species list for moves on to 43 with one addition today:
- Reed Bunting

Also noted:
- 1 Buff-tailed Bumblebee (Bombus terrestris)
- *Oxford Ragwort (Senecio squalidus) in flower

Growing out of the dam / retaining bank were several of these flowering Oxford Ragwort plants (Senecio squalidus).

And the flowers in close-up. Note all the flower bracts are black tipped. This plant is native to the slopes of Mount Etna in Sicily and escaped from the Oxford Botanical Gardens in 1794. It is now widespread in the UK. It starts flowering much earlier than the native Common Ragwort (Senecio jacobaea). Looks like an aphid on one of the rays of the right-hand flower.

Trench Middle Pool: 10:10 – 10:45

(9th visit of the year)

- A Grey Wagtail again

Birds noted flying over / near here:
- 2 Lesser Black-backed Gulls: both adults

Hirundines etc. noted:
None

My 2021 bird species list for here remains at 40 with nothing new today:

Also noted
- 1 Terrapin sp. (probably Yellow-bellied Slider). First of year anywhere for me.
