This morning's sunrise.
A plethora of butterfly photos today. Here is a female Green-veined White (Pieris napi). In all the 'white' butterflies females have four dark spots, one on each wing: males have just two dark spots, only in the forewing.
And the underside of a different specimen. I am not sure this is a female – I cannot make up my mind whether there is a dark mark in the hind-wing.
A Speckled Wood (Pararge aegeria).
A male Gatekeeper (Pyronia tithonus). Males show the brown mark in the centre of the forewing.
Another pristine Peacock butterfly (Aglais io). There were two this morning the other being the only butterfly I have seen so far on the large flowering Buddleia sp. alongside Teece Drive.
Today's highlight was this male Small Copper butterfly (Lycaena phlaeas). This is only my second record of this species here, my first was as recently as 03 June this year.
A second generation male Common Blue butterfly (Polyommatus icarus).
This specimen is rather worn with brown showing through.
Not quite sharp but it shows it feeding through his long tongue.
A very faded Pale Straw Pearl moth (Udea lutealis). All the markings, faint at the best of times, have worn away.
A Common Wasp (Paravespula vulgaris) caught up in a spider web. Somewhat unusual as this species is usually strong-enough to break free. A small midge is present as well.
A male Southern Hawker (Aeshna cyanea) I found alongside the public path at the West end.
It flew off when a passing cyclist flushed it. Luckily I noted it flew up in to a nearby tree.
A very smart male Common Blue Damselfly (Enallagma cyathigerum).
A male Blue-tailed Damselfly (Ischnura elegans). I think this is a rather late date for this species to be flying.
Today's unidentified fly.
A small beetle I found. It seems to be the same species as I noted on the same tree a few weeks ago. The background here is my fingers.
This spider was sprinting down one of the street lamp poles: I think probably a Common Candy-striped Spider (Enoplognatha ovata).
The reflections make this photo hard to look at. One of the adult Great Crested Grebes is seen bringing in a fish for the juvenile on the other parents' back. Meanwhile a second juvenile is alongside an adult.

(149th visit of the year)
Bird notes:
- A duck Mallard seen with a single duckling.
- Probably more Coots than I recorded. Almost all the birds were resting en masse along the East side of the island and it was almost impossible to separate them. One bird noted was still valiantly sitting on a nest.
- One of the singing Robins was performing its rather more melancholy Winter song.
Bird(s) noted flying over here:
- 1 Sparrowhawk
- 4 Jackdaws
Warblers noted (the number singing in brackets):
- *1 (1) Willow Warbler
- 10 (0) Chiffchaffs
- 1 (0) Blackcap
Hirundines etc., noted:
- 7 House Martins
Noted on / around the water

- 1 Cormorant: arrived
- 1 Grey Heron
Noted on / beside the street lamp poles around the water etc.:

A Grey Heron settles on a tree-top. Many people are surprised to see this species on tree-tops but of course they nest high up in trees so they are happy at height.
The long supercilium identifies this as a Willow Warbler. The rather short, thick and pale bill are also features to note.
This fungus appears at the top end every year around this time. It has been suggested to me they are Peppery Milkcap (Lactarius piperatus).
A smart spider resting on one of the street lamp poles.

This is a Small Grey moth (Eudonia mercurella). Just about the only 'grey' species still flying.
A Yellow-barred Brindle moth (Acasis viretata). Looks green and not yellow to me. Don't blame me – I didn't name it!
