Priorslee Balancing Lake and The Flash

9.0°C > 18.0°C: Fine. Areas of mostly thin high cloud took the edge off the sun at times. Very light wind. Excellent visibility.

Sunrise: 04:53 BST

* = a species photographed today
$ = a new species for me in this area

Priorslee Balancing Lake: 04:50 – 06:05 // 07:10 – 09:45

(126th visit of the year)

Bird notes:
- the Common Peafowl (Peacock) was heard again c.05:00. Also "foreign" was a cockerel heard crowing c.07:15 either from the Ricoh grounds or nearby properties.
- the seven Greylag Geese goslings present and correct. Their parents were the only other geese present until seven Canada Geese arrived from the North at c.09:35.
- just the trio of almost independent Mallard ducklings seen. Other hiding in the reeds?
- a pair of Tufted Duck here with none at The Flash.
- three juvenile Coots seen from a new-to-me brood.
- back to six Great Crested Grebes. However two birds were sitting alongside reeds and might have had a partner inside on a nest?
- a trio of Lesser Black-backed Gulls (two adults and very bleached and faded (near?) adult) were on the football field c.05:45.
- a Great Spotted Woodpecker was seen flying East over the Teece Drive gate c.09:20.
- a family party of Blackcaps was seen in the Ricoh hedge
- both Common Whitethroats noted singing again.
- a Garden Warbler was singing alongside the M54 today. The same bird?
- two Mistle Thrush flew out of the Ricoh grounds c.09:15. No song heard.

The sunrise this morning through the high cloud.

The tone of the back indicates this is a Lesser Black-backed Gull. Areas in the wing are very faded and / or bleached. When I saw it standing on the football field I thought it was a Herring Gull. From the bill colour this has to be an adult or perhaps a fourth year bird. Very unusual.

Peering out between the vegetation is a juvenile Blackcap – note the gape line.

And more visible here. I think that is vegetation around the bill-tip and not insect food.

After spending ages trying to get a clearer shot it, or another in the brood, decided to break cover and sit on the fence around the sailing club's yachts. Juveniles of both sexes have brown caps like the female. Perhaps to stop aggression from males, though I have never read that as an explanation.

A Speckled Wood butterfly Pararge aegeria. A particularly dark individual.

A Meadow Brown Maniola jurtina butterfly: my first May record of this species

It was sitting in full sun and it was difficult to photograph this Diamond-backed Moth Plutella xylostella: and show the characteristic markings on the abdomen. This species is a fairly common resident and frequently occurs as a migrant, sometimes in huge numbers along the South Coast. It may be "common" but my only other record here was 04 June 2016.

I usually see a few of these day-flying Mint Moths Pyrausta aurata along the South scrubby area where there is plenty of Water Mint Mentha aquatica

This moth is a Brindled Tortrix Ptycholoma lecheana which used to be known as Leche's Twist Moth (why?). I see one or two of this species most years.

A slightly better photo of a Silver-ground Carpet moth Xanthorhoe montanata. It would help if I did not see them around dawn in shaded areas.

I seemed to have seen many more of these Red Mason Bees Osmia bicornis this year.

Not my best but a photo of a spectacular-looking ichneumon wasp, probably a male Ichneumon xanthorius

A female Common Dronefly Eristalis tenax. Not easy to separate females of this species from female Tapered Dronefly E. pertinax. The leg colour clinches the ID here.

And another female captured in flight. On fine days in woodland rides there can be dozens of males hovering to mark their territory, combining to make a droning sound which gives the species their name.

This hoverfly is a Tuberculate Stripe-back Parhelophilus frutetorum. All the species in this genus are similarity orange-toned – and hard to separate! It seems to be trying scratch its back (or clean its wings?)

One of the Syrphus species of hoverfly. Perm one of S. ribesii / S. vitripennis / S. torvus.

Not at the best of an angle this is my first Compost Hoverfly Syritta pipiens of the year. The easiest identification feature of the swollen hind femur is just about visible.

It may look like a bumblebee but it isn't: the antennae are too short. It is a Bumblebee Plume-horned Hoverfly Volucella bombylans. This species has two forms: this the form plumata with a white tail. And the nominate form, bombylans, with a rufous tail. This individual seems to have body damage.

Here is a female Black Snipefly Chrysopilus cristatus: with a very different abdomen – more robust and with a bold pattern. As with many flies her eyes are further apart than those of the male.

This wolf spider Pardosa sp. is probably a female dragging its egg-sac full of spider-eggs.

On the basis of the large pedipalps these are two male Long-jawed Orb-web Spider Tetragnatha sp. on a street lamp pole pre-dawn. It is possible they are in dispute over a third (a female?) on the extreme right. It occurs to me to wonder whether the species in this group can be further distinguished by habitat. Are those that inhabit lamp poles different from those that sit in webs in vegetation?

This is Pineappleweed also known as Wild Chamomile Matricaria discoidea.

Plane of the day. A Boring 747 Series 400 Jumbo of Kalitta Air, based in Ypsilanti, not far from Detroit in Michigan. This 1997-built freighter operated with Korean Air Cargo for just over 20 years before being bought by Kalitta. Not easy to see is confirmation that it was built as a dedicated freighter: it has a shorter upper deck as there is no passenger space, only crew rest areas.

And, courtesy of FlightRadar24 here is the routeing from Anchorage, Alaska to Fairford in Gloucester. The CMB flight code indicates it is a US Military hire, no doubt bringing supplies to support the US Air Force bombers detached to Fairford as part of Operation Epic Fury against Iran.
