Priorslee Lake and The Flash

1.0°C > 8.0°C: Clear and frosty start with mist low over the water. Puffy clouds developing. Keen N breeze increased fresh at rimes. Very good visibility.

Sunrise: 05:18 BST

Priorslee Lake:

(78th visit of the year)

Bird notes:
- The drake Gadwall remains, doing very little.
- Just a single drake Mallard and that flew in.
- At least 100 hirundines (plus two Swifts) low over the water. Determining the number of each species not easy. Seemed initially that Sand Martins outnumbered Barn Swallows. Later it seemed there were more House Martins than anything else.
- Later still at least 70 hirundines were over the ‘football’ field area (perhaps the same birds and possibly escaping an unseen predator?). c.15 Barn Swallows were at reasonably low-level with >50 martins very, very high up. They were not calling to aid identification but seemed to be mainly Sand Martins. A few minutes later they had all gone.
- Neither the Blackcaps nor the Garden Warblers seemed too disposed to sing. Perhaps the cold wind? Perhaps too busy nesting?

Birds noted flying over / near here:
- 2 Canada Geese (pair outbound)
- 4 Lesser Black-backed Gulls: three (near) adults; one first year.
- 2 Stock Doves
- 5 Wood Pigeons
- 1 Jackdaw
- no Rooks again

Birds noted on the academy playing field:
- 1 male Pheasant
- 4 Starlings, but these soon flew and were part of ....

... up to 17 Starlings on the ‘football’ field

Count of hirundines etc logged:
See notes
- 2 Swifts
- >30 Sand Martins
- >25 Barn Swallows
- >30 House Martins

Count of warblers logged (singing birds in brackets):
- 10 (10) Chiffchaffs
- 17 (15) Blackcaps
- 1 (1) Garden Warbler
- 5 (5) Common Whitethroats again
- 7 (7) Reed Warblers again

Counts from the lake area:
- 2 Mute Swans
- 1 (1♂) Gadwall again
- 1 (1♂) Mallard only
- 1 Grey Heron, very briefly
- 1 Little Grebe heard only
- 4 Great Crested Grebes again
- 3 Moorhens again
- 9 Coots
- 1 Common Sandpiper again
- 2 Lesser Black-backed Gulls: both (near) adults, briefly, together.

On / around the street lights:
Nothing

Other insects etc. noted:
- 1 Red-and-Black Froghopper (Cercopis vulnerata)
- 1 Alder Fly (Sialis lutaria)

Plant species recorded for the year at this site:
- Water Mint (Mentha aquatica)

Without shadows across the breast and neck this would be a classic singing male Chaffinch.

I found this plant by accidentally standing on another close-by. It is Water Mint (Mentha aquatica), not yet in flower but certainly with a strong smell when the leaves are crushed.

The Flash:

(65th visit of the year)

Bird notes:
- It has been reported that the cob Mute Swan has killed all the Canada Goose goslings. None was noted by me.
- No Mallard ducklings located.
- Many of the Tufted Duck seen climbing on and off the island again.
- Two broods of Coots again. A well-grown juvenile alongside Derwent Drive, some distance from any nest. At least two off a nest in one of the cut-offs – nest site well obscured by overhanging trees.
- One (near) adult Lesser Black-backed Gull present throughout. When a second arrived they greeted each-other with the ‘long call’ with head thrown back and bills raised to the sky. They then started to ‘dance’ around for a while before separately bathing.
- One of the Blackcaps had me greatly confused. What seemed to be a Song Thrush started singing before tailing off as a Blackcap song. This was repeated several times before the Blackcap repositioned and I realised it was the almost seamless join of two different birds initially sitting very close together. A different location for the Song Thrush from the bird heard at the start of last week.

Birds noted flying over / near The Flash:
None

Hirundines etc logged:
- 1 Barn Swallow

Count of warblers logged (singing birds in brackets):
- 6 (5) Chiffchaffs
- 6 (5) Blackcaps
- 1 (1) Garden Warbler

Counts from the water:
- 3 + 9 (1 brood) Mute Swans
- 4 Greylag Geese: all arrived
- 10 Canada Geese, only
- 24 (10♂) + 0 (no broods) Mallard
- 11 (6♂) Tufted Duck
- 2 Great Crested Grebes again
- 3 Moorhens
- 16 + 3 (2 broods) Coots
- 1 Common Sandpiper again
- 2 Lesser Black-backed Gull: (near) adults

Nothing else of note

Five of the cygnets ‘break cover’ and decline to be brooded by the pen Mute Swan.

Later on the water. But how many? At least seven? Eight?

All nine here. Good news. Normally there are one or two very early losses from a clutch this size. Lets hope the parents take more interest in them than they did with last year’s brood.

Today’s dreadful photo but anything that blurs the ugliness of very young Coots is probably a bonus. Seemingly one parents doesn’t share my opinion.

Wood Pigeons are not known for their nest-building skills – a few twigs to stop the eggs rolling away will usually do. Almost half a nest here. Some added greenery to decorate it. How nice.

-------------------------------------

After yesterday's tranquil time on the Flash, today was a different story.

Sorry about the photo quality but this was all happening on the other side of the lake from me. I think the swan attacked a Canada Goose cygnet.

In the first photo you can see the Swan looking down whilst there appears to be a cygnet on the right under an adult goose wing.

The Swan was looking down in a number of the photos and the Canada Goose has reacted by attacking the Swan in the other photos.
