Priorslee Lake: 07:15 – 09:20
Location

Sunrise: 06:22

c.+5°C > +8°C: Broken cloud to start soon filled in, but clearance from E at 09:45. Calm, then light N breeze. Moderate visibility, becoming good

Highlight this morning was my first Green Woodpecker of the year calling at the lake

(39th visit of the year)

Notes
- 2 first year Swans flew in but were soon persuaded to move on
- back to regular 5 Gadwall this morning
- 2 single Lapwings over - perhaps the same one twice?
- at least 11 Siskins in the trees today
and
- 1 flightless female Dotted Border moth on the lamps

- 15 Great Crested Grebes again
- 21 Moorhens yet again
- 62 Coots
- 8 Black-headed Gulls

Not often you see the outer tail feathers of a Great Spotted Woodpecker – just two bands. A female here – no red on the nape.

Two Great Crested Grebes in full punk display.

These two Moorhens seemed to be getting friendly, but ...

 ... then decided against it.

This Cormorant too tired to stand on the platform and spent the whole time lying down. Note just a few white feather-tips on the neck-ache.

This is supposed to look like this: the small dots are 100s of small 'midges' that were swarming around me this morning – hurry up summer migrants and hoover them up.

This a female Dotted Border moth – like many species of moth that fly in winter the females are flightless with vestigial (as here) or no wings. It is thought this allows the females to devote all their energy to egg-production. Dispersal is made not by the female laying eggs on suitable food-plants but by the caterpillars, as soon as they emerge, climbing stems and using a silk thread to acts as a spinnaker – just like many species of spider.
