Priorslee Lake and The Flash

Priorslee Lake:  04:20 – 06:05 // 07:00 – 09:10

7.0°C > 15.0°C:  A few thin mostly high clouds. Calm with light SW wind later. Excellent visibility

Sunrise: 05:01 BST

Priorslee Lake:  04:20 – 06:05 // 07:00 – 09:10

(134th visit of the year)

Bird notes from today
- The Great Crested Grebes have lost one of their offspring. Only one of the other pair was seen.
- More juvenile Coots in the open today. One of yesterday’s broods was not seen.
- At 05:40 three Lesser Black-backed Gulls appeared overhead. One was carrying what seemed to be a slice of bread in its bill and this one, and then one of the others, veered toward the lake, the third bird carrying on. The first bird seemed to be ‘playing’ with the bread, dropping it and then diving to catch it again in mid-air. Eventually it fell in the water and both gulls dived down to the water (“I’ve told you before not to play with your food”). At this point two pairs of Tufted Ducks were seen to fly off from the NE area, though I had been in that area minutes beforehand and seen nothing. Not sure the two incidents were necessarily related. The Gulls stayed a few minutes and left.
- Some 10 minutes later another Lesser Black-backed Gull was seen on the ‘football field’ – most unusual (there was yet another briefly on the water much later).

It was the best of sunrises this morning with colour changing all the while. Really red at, gulp, 04:45. 

And really, really red at 04:50. 

Mellowed out but still pretty spectacular at 05:25 

With wreathes of mist as well. 

How could I resist this endearing trio of Mallard ducklings snuggled up? 

The Lesser Black-backed Gull arrives with its slice of bread. 

Here it is snatching it in mid-air.

This is a different adult Lesser Black-backed Gull in what I call the ‘football field’. In fact the different green in the foreground is a plastic cricket pitch, not that the field seems to be used for anything other than dog-exercising these days.

Nothing special: just a Wood Pigeon in super light. 

A Speckled Wood butterfly in good light. 

A not-very-blue (as yet) male Common Blue Damselfly.

This is a female Large Red Damselfly. Only my second record of this species here – the previous was on 10 May 2017.

Not entirely sure about this bee sp. May be a Field Cuckoo Bumblebee (Bombus campestris). 

Rather similar though this bumblebee has and extra band and seems to be an Early Bumblebee (Bombus pratorum). ‘Early’ refers to its emergence and there are several broods throughout summer.

A very distinctive hoverfly with a ‘wasp-waist’. Cannot be a wasp sp. as the antenna are too short. It is the species Baccha elongata (no vernacular name). A new species for me.
This, on the other hand, has long antenna. Just visible here is the yellow band across the body. 

As this insect comes it to land the wings stay open for a very short while allowing the body marking to be seen. It looks somewhat like a Cephas sp. of sawfly. I can find nothing on the web that identifies this species

 Is it past the watershed? A pair(?) of Red-and-Black Froghopper (Cercopis vulnerata).

Always some days after its yellow cousin is this Blue Flag Iris (Iris versicolor), the first of the year.

The Flash:  06:10 – 06:55

(128th visit of the year)

Notes from here:
- There are more juvenile Coots than I logged. I only noted one from the original brood of three – I am sure the other two were hiding. Then I noted two on a nest at the S end and these were obviously some days old and presumably were still being brooded during previous visits. Lastly a dog-walked reported seeing a group of new juveniles chasing after a parent, though I could not locate these.
- The Garden Warbler was singing intermittently again.

Birds noted flying over / near The Flash:
None

Hirundines etc. noted:
- 6 Swifts again

Warblers noted (singing birds):
- 1 (1) Chiffchaffs
- 1 (1) Willow Warbler
- 3 (3) Blackcaps
- 1 (1) Garden Warbler

The counts from the water:
- 3 + 5 Mute Swans
- 4 Greylag Geese
- 22 Canada Geese
- 20 (14♂) + 5 (1 brood) Mallard
- 9 (6♂) Tufted Ducks
- 2 Great Crested Grebes
- 3 Moorhens
- 31 + >3 (>2 broods) Coots

At or around the lower pool (singing birds):
