Priorslee Lake and The Flash

Priorslee Lake: 07:45 – 09:30
The Flash: 07:15 – 07:40

c.8.0°C > c.12.0°C: Fine and clear start with thin low cloud later. Moderate E breeze. Good visibility

Sunrise: 04:47 BST

Priorslee Lake: 07:45 – 09:30

(71st visit of the year)

Cooler start this morning with fewer warblers singing and fewer broods of Coot on the water. Also one of the broods of Mute Swans failed to show

Other notes from today:
- a Buzzard being harried by Magpies again: I wonder whether this is because the Magpies have unfledged / recently-fledged juveniles to protect
- a Wood Pigeon seen carrying a sticks as if it is still nest-building. I saw one doing this at The Flash yesterday and dismissed it as aberrant behaviour
- 2 Collared Doves over: despite this species being regular around the estate and at The Flash this is my first record here since 8th February!
- in addition to the one or two Sly Larks heard singing over the fields to the E of Castle Farm Way a Skylark flew E over the lake – an unusual date to see one overhead
and
- the following species of butterfly noted – all new for me here this year
- Speckled Wood
- skipper sp.
- no moths
- 3 species of damsel-flies
- Common Blue Damselfly
- Azure Damselfly
- Blue-tailed Damselfly
- three hoverfly species
- Helophilus pendulus (The Footballer)
- Eristalis sp. probably E. tenax (Common Drone-fly)
- Parhelophilus sp. (the three sps. are not separable without genitalia examination)
- one Crane Fly species
- Common Crane-fly (Tipula oleracea)
- the following currently common flies
- Black Snipe flies (Chrysopilus cristatus)
- three species of ladybird
- Harlequin Ladybird (Harmonia axyridis)
- 7 Spot Ladybird (Coccinella 7-punctata)
- 16 Spot Ladybird (Tytthaspis sedecimpunctata) – a new species for me
with
- a few Common stretch-spiders (Tetragnatha extensa)

No new species of flowering plants noted today but
- yesterday’s Hedge Woundwort (Stachys sylvatica) is no more – strimmed when the grass alongside Teece Drive was cut

Today’s bird totals

Birds noted flying over / near the lake:
- 2 Cormorants
- 2 Collared Doves
- 2 Jackdaws
- 1 Sky Lark

Hirundines seen today
- 6 Common Swifts
- 2 Barn Swallows
- 4 House Martins

Warblers noted: figure in brackets is singing birds (not all the males seen might have been singing)
- 5 (5) Chiffchaffs
- 8 (8) Blackcaps
- 3 (3) Garden Warblers
- 2 (2) (Common) Whitethroats
- 5 (5) Reed Warblers

The counts from the lake area
- 3 + 3 (1) Mute Swans
- 2 Greylag Geese briefly
- 8 (7♂) Mallard
- 6 Great Crested Grebes again
- 2 + 3 (1 brood) Moorhens
- 23 + 8 (4 broods) Coots

This Goldfinch looks rather aggressive when viewed head-on ...

... but looks rather more benign with the highlight in the eye and side-on.

The hoverfly Helophilus pendulus (aka The Footballer).

... as is this – a different specimen.

This rather smaller hoverfly is one of the Parhelophilus sp. (the three sps. are not separable without genitalia examination).

Two Common Blue Damselflies, paired but not mating as yet.

And another pair.

A 7 Spot Ladybird (Coccinella 7-punctata). Just about the most common ladybird.

And a Harlequin Ladybird (Harmonia axyridis).

A very small ladybird and not a species I have recorded before – a 16 Spot Ladybird (Tytthaspis sedecimpunctata).

A Red-tailed Bumblebee (Bombus lapidarius). Only some individuals show an orange/yellow collar.

I am fairly sure this is a Nursery Web Spider (Pisaura mirabilis). The female carries her eggs in a ball until they are about to hatch when she makes a nursery web to protect them.

I like orchids: a collection of spikes on the dam.

And a close-up of the flowers showing the diagnostic lip shape of Common Spotted Orchid (Orchis (Dactylorhiza) fuchsii).

And
In the tunnel under Priorslee Avenue yesterday’s presumed Common Swift moth had re-orientated and from a better angle the markings could be seen to positively ID it.
