Priorslee Lake and The Flash

11.0°C > 14.0°C: Cloud clearing from the NW with sun after 06:30. Moderate NW wind. Very good visibility.

Sunrise: 05:10 BST

NB: * means there is a photo today.

Priorslee Lake: 04:22 – 06:00 // 06:55 – 08:48

(141st visit of the year)

Bird notes:
- The cob Mute Swan seemed to take little notice of the two Canada Geese that arrived. He arched his wings in threat but once they had moved on to the grass he lost interest.
- Most strange: yet again a single duck Tufted Duck present when I arrived but gone soon after. I don't think there was any immediate connection with the two birds that flew E – too dark to sex these at the time.

A 'half and half' morning. The cloud gradually slipped away SE and after c.06:30 it was sunny.

Could get no nearer the Great Crested Grebe family this morning. However better light enabled me to see there are at least two juveniles on the parent's back. One of them seems to be pecking the adult's neck.

A rather scruffy-looking gull with lots of bits missing. The outer primaries are regrowing as are the outer secondaries and the tail feathers. The very well-marked underwing and the all-dark bill point to a first-summer Lesser Black-backed Gull beginning its moult in to second-winter plumage. I confirmed this from the upper wing pattern as it flew on.

A juvenile Reed Warbler waiting to be fed.

Perhaps if I look pensive I'll get fed.

Or if I look for Divine inspiration?

Oh well!

A fine example you are setting. Do you not know that eating unripe fruit gives you stomach ache? As a female Blackbird you should know better.

Another?!

Not easy from this angle and with its wings closed. Just possible to make out the two white spots in the black circle on the underside of the forewing. So it is...

... a male Gatekeeper (Pyronia tithonus). Good of it to open its wings.

This tiny micro moth is a London Dowd (Blastobasis lacticolella). This species arrived in the UK, apparently from Madeira, c.1945 and is now widespread and common.

Not a grass moth as it might seem. This is one of many species of caddis fly – there are over 200 in the UK. The unusual posture might indicate it is a Molanna sp. Then again....

Probably all the overnight rain and the brisk wind but I was struggling to find any hoverflies this morning. The Field Bindweed flowers (Convolvulus arvensis) are usually a haven for them. All I found was this pollen-covered Common Wasp (Paravespula vulgaris).

I did eventually find a few hoverflies – this is a Cheilosia illustrata. The only vernacular name I can find for this species is Bumblebee Cheilosia which is not particularly helpful or apposite since it doesn't look like a bumblebee.

Probably the same Red-legged Shieldbug (Pentatoma rufipes) I have been finding. Today it wanted to know the time and came to look at my watch.

A seven-legged Dicranopalpus sp. harvestman. My second here this year and a species supposedly not around before August. Seems the harvest is getting earlier. With the very long palps this used to be an easy species to ID, but 'they' have now discovered that there are two almost identical species involved. Dissection needed to separate.
