Bird notes:
- the resident Canada Geese still have six goslings.
- the resident Greylag Geese now only have three goslings.
- a pair of Stock Doves was on the football field c.06:10. Yesterday I heard birds calling – well you can't call it a song - from three different locations.
- I believe there were two Lesser Whitethroats singing today. One was close to the Teece Drive gate singing quietly at c.05:10 only. Another was singing lustily from the small copse next to the water along the South side at 05:20 and again from 07:40 for at least 10 minutes.
- The Common Whitethroat was heard giving a scolding call just once. Otherwise it was neither seen nor heard

At last: a decent sunrise.

So we better have another view.

A Moorhen family at the lower pool between the lake and The Flash. Around the edges are four well-grown juveniles. Underneath the adult's bill is a much smaller juvenile. Is this is a runt from the same brood. Surely two broods cannot be so close together?

Two Grey Herons flying over together.

Pre-dawn a Blue Tit searched for spiders and flies on the fence around the multi-use play area.

A Plain Gold moth Micropterix calthella showing the yellow scales on its head. These soon wear off.

An unknown small ichneumon.

A very distinctive hoverfly. It is a Marmalade Hoverfly Episyrphus balteatus.

A Short Melanostoma hoverfly Melanostoma mellinum. In this view identification is relatively straightforward in that it is the only species in the group whose abdomen widens in the middle.

My first Blue-tailed Damselfly Ischnura elegans this year.

A hovering Dark-edged Bee-fly Bombilius major using it long proboscis to reach pollen deep in the flowers of Ramsons Allium ursinum.

A dagger fly Empis trigramma.

Not my best view of this Thick-headed Fly Myopa testacea. In this group the abdomen is tucked-under.

A Yellow Dung Fly Scathophaga stercoraria.

A large cranefly. It is Tipula luna

While this cranefly with an orange thorax is Tipula lunata.

Not easy to see with my LED torch giving some nasty reflections in the dew on the street lamp pole. It is a Kidney-spot Ladybird Chilocorus renipustulatus.

This beetle was also on a street lamp pole pre-dawn. It may be the longhorn beetle Grammoptera ruficornis.

One of the False blister beetles. It is either Oedemera lurida or O. virescens: They are separable mainly by size. I did not have a ruler!

An exciting-looking spider. It is one of the wolf spiders Pardosa sp.

A Long-jawed Orb-web Spider Tetragnatha sp. with breakfast.

 New flowers for the year: here is a Yellow Flag Iris pseudacorus.

This is Black Medick Medicago lupulina growing in some quantity along the dam-top.

A new species for me, identified by Obsidentify as Brooklime (Speedwell) Veronica beccabunga.

The Flash: 06:25 – 07:20

(103rd visit of the year)

Bird notes:
- I can confirm that there are five immature Mute Swans. The resident adults were seen with just three cygnets. I suppose it is possible that other cygnets were staying in the nest?
- yesterday's brood of Mallard ducklings not seen.
- Tufted Duck seem to come and go. Could they be spending time on the island? Could they indeed be breeding there? Time will tell perhaps.

Bird(s) noted flying over here:
None

Warblers noted (the figure in brackets relates to birds heard singing):
- 7 (7) Chiffchaffs
- 2 (1) Blackcaps
'nominal' warbler:
- 2 (2) Goldcrests

Noted on / around the water:
- 13 Canada Geese
- 1 Greylag Goose
- *7 + 3 (1 brood) Mute Swans
- 13 (10♂) Mallard
- 5 (3♂) Tufted Duck
- 5 Moorhens
- 23 + 9 (4 broods) Coots
- 2 Great Crested Grebes

Noted elsewhere around The Flash:

Beetles:
- Alder Leaf Beetle Agelastica alni: very many

The pen Mute Swan with her small brood of three cygnets.

Say "ah!"

I bet her baby Blackbirds can't wait for their delicious breakfast.
