Trench Lock Pool: 10:25 – 11:15

(9th visit of the year)

Velvet Scoter still present but not allowing close approach. There seems to be general agreement that this bird is an immature drake

One of the local birdwatchers told me the number and variety of gulls has increased since the opening of the tip / recycling centre at Hortonwood

c.25% ice

Other notes
- a drake Goosander made several circuits overhead and left to the E
- 23 of the Black-headed Gulls were on the lamps above the A442
- some gulls were coming and going: the counts were taken at 11:00
- a Pied Wagtail on the north bank was, surprisingly, my first of the year here

The counts from the water
- 2 + 3 Mute Swans
- 2 Greylag Geese
- 15 Canada Geese
- 30 (17?) Mallard
- 4 (4?) Shoveler
- 48 (19?) Tufted Ducks
- 1 (1?) Velvet Scoter
- 9 Moorhens
- 50 Coots exactly
- 108 Black-headed Gulls
- 138 Lesser Black-backed Gulls
- 12 Herring Gulls
- 1, possibly 2, Yellow-legged Gull

One of the four drake Shovelers broke cover to allow this shot.

The Velvet Scoter is still present.

The Velvet Scoter reacting to a low-flying gull! It does depend on the angle of the light: however it seems to me that this bird had more brown in the bill than it had a week ago. It must surely be a 1st winter drake.

For the record: a silhouette of the Goosander overhead. Identifiable in this photo by the bill shape (a Red-breasted Merganser is similar; is most unlikely inland; and would almost certainly show a wispy crest).

This is a really heavily marked adult winter Lesser Black-backed Gull: about as dark as they come.

Compare with this much paler individual.

A Herring Gull departing: probably a 4th winter bird – the slight dark mark on the 6th primary would not be present on a full adult.

What I take to be a winter adult Yellow-legged Gull: very smart with no head-streaking and slightly darker mantle than typical Herring Gulls. The bill does not look large-enough for a Caspian Gull, though I remain rather puzzled by the extensive area of white in the folded primaries. The bird immediately behind it is a 2nd winter large gull and may also be a Yellow-legged Gull. It looks rather grey on the mantle and the streaking is mainly confined to the lower part of the neck. The other birds are all adult winter Lesser Black-backed Gulls.

A much more typical colour on the mantle of this 1st winter Herring Gull – the all-black bill ages it, otherwise it almost looks like some 2nd winter birds.
