Passed in the dark and saw and heard very little
- >74 geese sp.: from calls most of these were Canada Geese but at least 2 Greylags amongst them

Priorslee Lake: 07:25 – 09:20

(175th visit of the year)

Other notes from today
- the geese flew out again when it was too dark to either accurately count or identify them
- the pair of Gadwall seems to have lost their duck Shoveler ‘shadow’
- the first Black-headed Gulls – just 4 – did not arrive until 07:48 but soon left; 3 (more?) flew in at 08:05 with a Lesser Black-backed Gull; no more than 25 were ever counted on the water. At least 108 flew through from the W and, unusually did not return
- just 14 Wood Pigeons in trees around lake and only 7 flying over: however >300 seen in the distance flushed from the trees in Wards Rough to the NE
- the Magpie roost count was done from a distance again
- no big groups of Jackdaws again and rather fewer birds
- a Chaffinch in the trees was the first I have logged around the lake for almost two weeks
and
- strangely no moths on the lamps after yesterday’s bumper count
- a stretch spider (Tetragnatha sp.) on a different lamp

Trench Lock Pool: 09:55 – 10:30

(11th visit of the year)

Highlight here was the calling Water Rail in the scrubby area at the S end. Only my 2nd record for here and my first for several years

Other notes
- most of the Canada Geese flew in
- unusually large count of Mallard
- 3 drake Shoveler new in
- only 3 Goosanders but, unusually, a higher number of drakes than ducks
- Little Grebes here: first for me this winter
- Coot numbers remain at unusually low level
- rather few gulls again

The counts from the water
- 2 + 3 Mute Swans
- 82 Canada Geese
- 45 (28♂) Mallard
- 3 (3♂) Shoveler
- 43 (21♂) Tufted Ducks
- 3 (2♂) Goosander
- 1 Grey Heron
- 2 Little Grebes
- 1 Water Rail (heard only)
- 5 Moorhens
- 37 Coots
- 53 Black-headed Gulls
- 6 Lesser Black-backed Gulls
- 3 Herring Gulls

Compare and contrast time: a drake Goosander in front of a drake Shoveler.

I did a bit of a double-take here: the immature gull in front of the adult Lesser Black-backed Gull looks rather larger and has a almost unstreaked head and neck. The mantle is clearly dark-enough to be a black-backed gull: could it be a Great Black-backed Gull? Not I decided ....

This, with the bird alongside an adult winter Lesser Black-backed Gull, shows that it not large-enough, not dark-enough on the mantle, the head is probably not white-enough and the bill is also not large-enough. Probably just a large male, certainly a 2nd winter bird and a Lesser Black-backed Gull (couple of Black-headed Gulls get in on the action).

Yet another double-take bird. Is this a dark Herring Gull (and therefore a possible Yellow-legged Gull); or a pale Lesser Black-backed? Before you answer consider the very pale end to the bill. Now? Actually I have no idea but suspect it is NOT a Yellow-legged Gull it is not smart-enough. The dull conditions and its refusal to fly to show its wing pattern means I will ‘pend’ it.

Trench Middle Pool: 10:35 – 10:55

(6th visit of the year)

Notes
- Mute Swan gone
- fewer Tufted Duck today: gone to Trench Lock?
- high numbers of Goosanders for here. All 10 nominally ‘brownheads’; several showing evidence of moult in to drake plumage
- Herring Gulls are rather unusual here

The counts from the water
- 65 Canada Goose
- 28 (22♂) Mallard
- 1 (1♂) Feral-type Mallard
- 14 (7♂) Tufted Ducks
- 10 (1♂) Goosander (see notes)
- 1 Great Crested Grebe
- 11 Moorhens
- 12 Coots
- 129 Black-headed Gulls
- 2 Lesser Black-backed Gulls
- 1 Herring Gull

Two brownhead Goosanders: rather different in size and with rather different shaped crests. The rear bird has paler flanks and some white feathering on the mantle: I suspect this means it is a drake yet to acquire breeding plumage.
This preening bird shows even more white feathering on the mantle: I am certain this one is a drake yet to acquire breeding plumage.
