Priorslee Lake and The Flash

10.0°C > 17.0°C: Early areas of high cloud increased for a while before moving away after 08:15. Light and variable breeze after a calm start. Very good visibility.

Sunrise: 05:28 BST

* = a photo from today

Back from two weeks in the USA and trying to cope with jet-lag.

Priorslee Lake: 04:55 – 06:00 // 06:50 – 09:20

(162nd visit of the year)

Bird notes:
- Two pairs of Great Crested Grebe with young – a pair with a single juvenile and a pair with two juveniles. Another pair with one bird sitting on a nest. A fourth pair apparently not nesting. Also a lone adult (though it could have a mate on a nest inside the reeds).
- 19 Black-headed Gulls on the football field at 05:50 were probably some of the same birds as seen at lake earlier.
- As birds undertake their post-breeding moult the only species heard singing this morning were Robin and Wren, very intermittently. A lone Song Thrush, gave a brief song.

Birds noted flying over here:
- 2 Canada Geese: outbound together
- 1 Greylag Goose: inbound
- 1 Feral Pigeon
- 1 Stock Dove
- 74 Wood Pigeons
- 3 Lesser Black-backed Gulls
- 30 Jackdaws
- 12 Rooks

Hirundines etc. noted:
None

NB: I have seen but a single Swift over Newport during the last two days so the other 30+ seem to have departed. End-July / early-August is the normal date for most Swifts to depart with a few stragglers possible until as late as mid-September.

Warblers noted (figures in brackets relate to singing birds):
- 6 (0) Chiffchaffs
- 8 (0) Reed Warblers
- 5 (0) Blackcaps

'Almost' a song from one of the Chiffchaffs and a Reed Warbler.

Counts from the lake area:
- 6 Canada Geese: arrived
- 2 + 4 (1 brood) Mute Swans
- 18 (?♂) Mallard
- 7 adult / juvenile Moorhens
- 63 adult / juvenile Coots
- 1 Little Grebe
- 9 + 3 (two broods) Great Crested Grebes

A stunning sunrise this morning. The best colour was before I could scamper(?) down to get it reflected in the lake.

Still very impressive though. A Mallard provides the foreground.

The colour was fading by now but the texture of the cloud is better illustrated here.

One of the resident Common Buzzards was sitting on a favourite lamp pole in Teece Drive and ignoring the begging calls of the juvenile.

Most unusually it allowed me to walk past it (albeit on the other side of the road) and take this view of its back, complete with a rather ragged feather about to be dropped. It is keeping a wary eye on me though.

With two white marks in the dark spot on the forewing of this butterfly it is easily identified as a Gatekeeper (Pyronia tithonus). The otherwise unmarked forewing indicates it is a female. The male shows dark shading across the middle of the forewing.

The most frequently seen 'grass moth' species at the moment is the Common Grass-veneer (Agriphila tristella). This photo shows the salient features well. A clearly delineated white streak that breaks in to three (or four) fingers and which is outlined more strongly towards the outer edge of the wing. When fresh, as here, there is a row of dots along the wing-tip.

The broad stripe on the thorax (the ante-humeral stripe) and the club-shape mark at the base of segment two on the body identify this as a male Common Blue Damselfly (Enallagma cyathigerum).

This resting scorpion fly Panorpa sp. shows that it has two pairs of wings and is thus not a true fly, these having a single pair of wings for flying with the hind-wings reduced to tiny pin-shaped halteres that act like gyroscopes. The name of the scientific order of true flies, Diptera, derives from their having just two wings.

An early instar of a Common Green Shieldbug (Palomena prasina).

With the very long pedipalps and often with its four pairs of legs held parallel and perpendicular to its body this used to be easily identified as a Dicranopalpus ramosus harvestman. Then it was noticed that there was another cryptic species, D. caudatus, visually identical and requiring the usual genitalia examination to separate. So Dicranopalpus ramosus/caudatus it has to be.
