Sunrise: 05:59 BST

Priorslee Lake:  04:35 – 06:25 // 07:20 – 09:30

(201st visit of the year)

Bird notes from today:
- Some of the cygnets were trying their wing-muscles today. The feathers are still much too short to support flight.
- A Grey Heron flew off W at 04:45 and no more seemed to be present. It may have returned as one was present by 07:45. Or it may have been the bird that flew over at 09:25.
- The earlier breeding pair of Great Crested Grebes now have at least two small juveniles from a second brood - keeping their distance and hard to be certain. The second pair still have one well-grown juvenile. The third pair, relatively recent arrivals, were seen together only first-thing: thereafter only a single adult noted. The fledged juvenile present could be from the first brood or the 'extra' bird first seen two weeks ago.
- Still just a single very new juvenile Coot located from the latest brood. An adult in the same area was still optimistically collecting nesting material.
- A Hobby flew fast over W-bound at 06:20.
- A party of 51 Racing Pigeons was released nearby c.08:15 and these birds flew off NW. Two other small groups were more likely Feral Pigeons
- At c.08:30 a large group of Wood Pigeons was put up from the fields to the E with at least 94 of these flying off W (these included in the count of birds overhead). At least 70 more circled back (these not included in the counts).
- In addition to the three Collared Doves that flew over another bird was, unusually, flushed from trees in the SE area.
- Four Swifts arrived at 06:00 but had gone by 06:20. Two by 07:50 assumed to be different birds.
- Four small groups of Barn Swallows flew through. Did not seem to be migrating as some birds flew N and others W.
- at least 60 House Martins high over to W at 06:15
- 34 Pied Wagtails on the ‘football' field at 06:20.

- 57 Black-headed Gulls: no juveniles
- 4 Lesser Black-backed Gulls ('gas and go' as usual)
- 1 Kingfisher

On the lamp poles pre-dawn:
- 6 Common Grass-veneer moths (Agriphila tristella)
- 2 green lacewings, likely Chrysoperla carnea
- 1 harvestman Dicranopalpus ramosus again

The following logged later:
- Butterflies
        - Meadow Brown (Maniola jurtina)
        - Gatekeeper (Pyronia tithonus)
- Moths (in species order):
        - a few unidentified grass moths
        - 1 Mother of Pearl (Patania ruralis): *** first of year
- No damselflies etc:
- Hoverflies (in alphabetic order of scientific name):
        - Tapered Drone Fly (Eristalis pertinax)
        - Common Drone Fly (Eristalis tenax)
        - Volucella inanis (wasp mimic)
And other things:
- a few Honey Bees (Apis mellifera)
- 1 Common Carder Bumblebee (Bombus pascuorum)
- several wasps (Vespula sp.)
- 2 Grey Squirrels
- 1 pipistrelle-type bat

A rather cheerless start with cloud spreading from behind me.

A Dunnock of course. This species has been VERY quiet for over a week now - I guess they are moulting: post-breeding; or in to first adult plumage. As a result they do not want to be seen.

This moth is a Mother of Pearl (Patania ruralis). It gets its name as fresh specimens in good light do indeed iridescence like mother of pearl. This specimen is a bit too worn. Note how the antenna are held back, more or less alongside the body.

Yesterday the hornet-mimic hoverfly Volucella zonaria: today the more wasp-like V. inanis. Note that all the tergites are yellow, whereas V. zonia had chestnut on tergite 2.

Still an impressive-looking - and quite harmless - insect. The yellow face shows well here. 

Even better from this angle. Note the really thin and short antenna, typical of nearly all hoverflies.

A Common Carder Bumblebee (Bombus pascuorum).

The Flash:  06:30 – 07:15

(192nd visit of the year)

Notes from here:
- The latest brood of Mallard is now down to a single duckling.
- Only one of the usual duo of adult and juvenile Great Crested Grebes was noted
- The single House Martin overhead sounded like a juvenile.
and, all on lamp poles:
- 1 Common Grass-veneer moth (Agriphila tristella)
- 1 White-streak Grass-veneer moth (Agriphilla latistria)*** new for me in Shropshire
- 1 Elbow-stripe Grass-veneer moth (Agriphila geniculea)*** first of the year
- 1 Willow Beauty moth (Peribatodes rhomboidaria)***also first of the year
- 1 Harlequin Ladybird (Harmonia axyridis) pupa
- 1 harvestman Leiobunum rotundum again

Birds noted flying over / near The Flash:
- 7 Feral Pigeons (2 groups)
- 5 Wood Pigeons

Hirundines etc. noted:
- 1 House Martin only

Warblers noted (singing birds):
- 4 (1) Chiffchaffs
- 2 (0) Blackcaps

Counts from the water:
- 3 Mute Swans
- 1 Greylag Goose
- 6 Canada Geese
- 36 (19 drakes) + 1 (1 brood) Mallard
- 22 (10 drakes) Tufted Ducks
- 1 + 1 (1 brood) Great Crested Grebes only
- 2 + 1 (1 brood) Moorhens
- 16 Coots again
- 2 Black-headed Gulls again: no juveniles

I have had a good read of the literature for grass moths. The wide stripe reaching the cilia (the narrow fringe at the edge of the wing) and not 'spreading' like it does on Garden Grass-veneer suggests this is a White-streak Grass-veneer (Agriphilla latistria). New for me in Shropshire, likely overlooked amongst all the other grass moths.

A slightly smaller grass moth with markings across the wings is Elbow-stripe Grass-veneer (Agriphila geniculea).

My first Willow Beauty moth (Peribatodes rhomboidaria) of the year. Another common and rather variable species.

Some weeks since I last saw one of these and I forgot what it was. The internet to the rescue - a pupa of a Harlequin Ladybird (Harmonia axyridis).

- 1 Chiffchaff now calling at the upper pool

also
- 1 Common Grass-veneer moth (Agriphila tristella)
