- A single Swift at 04:40 stayed alone for c.10 minutes. Another with 6 House Martins briefly at c.07:20

A 'record shot' of the Curlew over at 05:20

A Common Whitethroat looks pensively out.

A Reed Warbler on the hunt for food.

I'm not sure I ever realised that Speckled Wood butterflies (Pararge aegeria) have more rings than Ringlet butterflies (Aphantopus hyperantus)

It is a strange evolution path has come up with the wing-shape of a Comma butterfly (Polygonia c-album).

A Mother of Pearl moth (Pleuroptya ruralis). Get the light at the right angle and the effect is amazing. I disturb this species from the grass more or less annually.

One of the many Andrena mining bees. This species – whatever it is(!) - is one that shows a well-developed hind leg for capturing pollen.

Had to double-check this bumblebee. Those with banded abdomen are sometimes cuckoo bumblebees. Not so here: 'just' an unusual view of a typical Common Carder Bee (Bombus pascuorum).

This pan view of a Buff-tailed Bumblebee (Bombus terrestris) shows how the apparent white tail of UK populations of this species has a thin buff band separating the tail from the rest of the abdomen.

Four for the price of one: two Cheilosia illustrata hoverflies (with pale bands across their middle); at the bottom a male Long Hoverfly (Sphaerophoria scripta); at the top the rear of a Buff-tailed Bumblebee (Bombus terrestris)

A particularly fine specimen of a Marmalade Hoverfly (Episyrphus balteatus) in contrast with one of those confusing hawk-things. Haven't managed to find one with dark tips to the petals.

The Fox – seems to be quite young – notices me...

..scarpers!

The Flash: 05:55 – 06:50

(119th visit of the year)

Bird notes:
- One of the Mute Swan cygnets lagging a long way behind the main group with the pen. The cob was 'resting' on the island.
- All geese numbers somewhat suspect as they flushed when a dog barked at them as I was part way through the count. Many then decided to take refuge inside the island.
- Five Greylag Geese tried their new wings for a half-circuit of the water. This seemed to inspire two Canada Geese to have a go, but they barely lifted off.
- Three of the cross-bred geese always seem to be with one of the Greylags and slightly separate from any other geese. The other cross-breed is usually in with Canada Geese.

Birds noted flying over / near The Flash:
- 1 Common Buzzard
- 1 Feral Pigeon
- 2 Wood Pigeons

Hirundines etc. logged:
None

Count of warblers logged (singing birds in brackets):
- 2 (1) Chiffchaffs
- 3 (3) Blackcaps

Counts from the water:
- 3 + 7 (1 brood) Mute Swans
- 52 Greylag Geese
- 4 Greylag x Canada Geese
- 101 Canada Geese
- 14 (?♂) Mallard (see notes)
- 15 (12?♂) Tufted Duck
- 1 Grey Heron: arrived
- 2 + 2 (1 brood) Great Crested Grebes again
- 2 Moorhens again
- 12 + 17 (? broods) Coots

Otherwise of note, on different lamp poles:
Strange things asleep on the poles this morning
- 1 Little Grey moth (Eudonia lacustrata)
- 1 Common Carder Bee (Bombus pascuorum)
- 1 Migrant Hoverfly (Eupeodes corollae)

The incoming Grey Heron decides to perch at the top of the tallest tree on the island.

After 29 days the 5 remaining Mute Swan Cygnets are still going strong. Last year, as you may recall, we had 9 but ended up with just 1, after a Mink devastated the family. This year it has been Mink clear and even though we lost 2 within the first two days, these guys I think will do really well.
