Priorslee Lake
Map

Evening Update: 4:15pm

1 Caspian Gull present via BirdGuides. (Observer Unknown)


Morning Report: 7:35am - 9:47am

11.5°C throughout:  cloudy and mild with occasional light drizzle. Fresh / strong SW wind. Good visibility.

The strong wind affected most things today. Small birds were mainly hiding away and even larger birds struggled.

(154th visit of the year)

Counts of birds flying over the lake (therefore in addition to those on / around lake)
- 34 Canada Geese
- 11 Black-headed Gulls
- 64 Lesser Black-backed Gulls
- 24 Herring Gulls
- 9 Feral Pigeons
- 2 Pied Wagtails
- 2 Redwings
- c.520 Jackdaws
- 18 Rooks

In the windy conditions no sensible counts of birds leaving roosts around the lake could be made.

The counts from the water
1 Little Grebes
2 Great Crested Grebes
2 Swans
1 Greylag Goose
6 (3) Gadwall
9 (6) Mallard
71 (42) Tufted Duck
12 Moorhens
187 Coots
116 Black-headed Gulls
6 Lesser Black-backed Gulls
24 Herring Gulls
3 Great Black-backed Gulls

Other notes
Greylag Goose left at 7:50am before the Swans awoke to chase it off.
With many fewer large gulls and these all twisting and turning against the wind it was possible to specifically identify them all.
Even the Kingfisher – normally a speeding arrow – was seen tacking across and struggling with the wind.
Cetti's Warbler not heard again this morning.
and
Another Mottled Umber moth.

Map

(59th visit of the year)

Notes
One of the drake Shoveler was a 1st year bird yet to acquire full breeding plumage.

The counts from the water
4 Little Grebes
3 Great Crested Grebes
3 Cormorants
1 Grey Heron
2 Swans
1 Canada Goose
32 (19) Mallard
3 feral Mallard-type ducks
6 (4) Shoveler
2 (2) Pochard
46 (22) Tufted Ducks
1 (0) Goosander
5 Moorhens
164 Coots
c.320 Black-headed Gulls
27 Lesser Black-backed Gulls
17 Herring Gulls

Two of the drake Shoveler at Trench – no mistaking that snout! The nearer bird is likely a 1st winter bird – whatever it is still to complete the moult in to breeding plumage.

Here are two drakes and two duck in flight: note the 1st winter drake shows some white on the chest.

A ‘brownhead’ Goosander of course: the mottling on the flanks and the paleness of the flight feathers suggests to me that this is a 1st winter drake beginning to acquire adult plumage. The literature does not illustrate birds in transition.

... however the stretched wing here is less supportive of the 1st drake theory.

... but then again the faint pink flush on the very white belly is a drake characteristic.

Time for a preen: a Great Crested Grebe gets in the picture as well.
