Priorslee Lake, The Flash, Trench Lock Pool and Trench Middle Pool

0.0°C > 3.0°C: Mainly clear with only a few clouds at times. Light W wind. Very good visibility.

Sunrise: 08:22 GMT

* = a photo today

Best wishes to all my readers. Here's to a less challenging 2021.

One of my better mornings with several highlights
- A pair of Wigeon dropped in to the lake where there was an adult Great Black-backed Gull and also two passing Ravens.
- A Chiffchaff was calling and then seen along the W end track (Silkin Way) at Trench Lock Pool.
- A Pink-footed Goose was with Greylag Geese at Trench Middle Pool.

Priorslee Lake: 06:50 – 09:32

(293th visit of the year)

- c.5% thin ice

Bird notes:
- The pair of (Eurasian) Wigeon spent about five minutes circling round and round checking out where to land before eventually settling c.08:15.
- Increased number of Pochard and Tufted Ducks. Likely some were from The Flash which had much more ice.
- A Sparrowhawk was patrolling the area much of the time. I record this species much less frequently here than at The Flash.
- A Water Rail was calling in the NE area. Many years since I logged one in this part of the lake. A tree fell in the drainage ditch that this species sometimes frequented and I saw them no more.
- c.125 Black-headed Gulls on the water by 07:10 - some roosted? Eventually at least 330 birds before they started to disperse.
- Usual remarkably diverse collection of large gulls considering the relatively small number of birds involved. An adult Great Black-backed Gull was good to see.
- I note that so often the passing Lesser Black-backed Gulls follow exactly the same line. I assume that from their height they can see landmarks to aim at?
- Great Spotted Woodpecker heard drumming again.
- Just one big group of c.130 Jackdaws. Scattered singles, small groups later. No Rooks.

Birds noted flying over / near here:
- *41 Greylag Geese: three concurrent groups, loosely inbound
- 1 (0♂) Goosander
- 2 Cormorants: singles
- 1 Sparrowhawk
- 1 Common Buzzard
- 7 Black-headed Gulls
- 61 Lesser Black-backed Gulls
- 3 Herring Gulls
- 17 Wood Pigeons
- c.150 Jackdaws
- 2 Ravens
- 2 Fieldfare
- 1 Redwing
- 1 Linnet

Apart from uncounted Magpies no birds were seen / heard leaving roosts around the lake:
Reed Buntings heard calling from the N side reeds pre-dawn: these too were not seen to leave though they were not heard calling or seen later

Counts from the lake area:
- 2 + 5 Mute Swans
- 1 Greylag Goose: departed
- 4 Canada Geese: departed with the Greylag
- *2 (1♂) (Eurasian) Wigeon: arrived
- 2 (1♂) Gadwall
- 10 (6♂) Mallard: 5 (3♂) departed
- 6 (5♂) Pochard
- 73 (48♂) Tufted Duck
- 2 Cormorants: arrived separately
- 2 Grey Herons
- 2 Little Grebes
- 6 Great Crested Grebes
- 1 Water Rail
- 5 Moorhens
- 128 Coots
- c.330 Black-headed Gulls
- 13 Lesser Black-backed Gulls
- 2 Herring Gulls: adult and immature
- 1 Yellow-legged Gull: (near?) adult
- *1 Caspian Gull: second winter
- *1 Great Black-backed Gull: adult

On / around the street lights etc. pre-sunrise:
Nothing

Of note later:
Nothing

A chilly sunrise.

A little colour later.

One of the three skeins of Greylag Geese that passed over more or less at the same time.

In amongst them was this strange individual with white outer part to its wings. The feet, as much as can be seen, look just like a Greylag's feet. I cannot think of any other goose species that it might be crossed with so it seems it is an aberrant Greylag. I have counted as such.

Difficult to 'freeze' the action of flying birds before sunrise. However the white in the wing of this drake (Eurasian) Wigeon is diagnostic.

The pair eventually settled on the water a long way away. Just visible is the yellow crown on the drake - the left-hand bird. They don't seem to be on speaking terms.

Makes a change from Coots on the sunrise-tinged water. A pair of Tufted Ducks.

I take photos of 'odd-looking gulls' and then have to try and identify them. I think an adult Caspian Gull. The mantle seems slightly too dark; and the head too white and too rounded for a Herring Gull. Large gulls start to loose the winter head-streaking soon after Christmas, some very quickly. It then becomes even more of a challenge ....

This adult Great Black-backed Gull was an early, brief visitor. Note its bulk, its white head (adults of this species do not have head streaking in winter) and the 'very black' back. A trio of drake Tufted Ducks in the background with one duck just about discernible.

The Flash: 09:35 – 10:24

(275th visit of the year)

- c.40% ice

Bird notes:
- Perhaps a second duck Goosander. I thought I saw two ducks tucked up against the island but later could only find a pair.
- Grey Wagtail seen again but not close enough to see whether it had rings.

Birds noted flying over / near The Flash:
None

Counts from the water:
- 3 + 5 (1 brood) Mute Swans
- 18 Greylag Geese: 10 of these arrived
- 19 Canada Geese
- 26 (15♂) Mallard
- 1 (1♂) Pochard
- 69 (35♂) Tufted Duck
- 2 (1♂) Goosander
- 1 Grey Heron
- no Great Crested Grebes
- 6 Moorhens
- 33 Coots
- *110 Black-headed Gulls

On the lamp poles, around the Ivy or elsewhere.
Nothing of note

Many Black-headed Gulls seem quite happy to stand on the ice.

I dared not move otherwise this Jay would have flown. So it comes, branches and all.

Trench Lock Pool: 10:34 – 11:05 // 11:45 - 11:54

(41st visit of the year)

- c. 70% ice

Bird notes:
- The recent single Greylag Goose back amongst the Canadas.
- Highlight here was the calling Chiffchaff, later also seen. One of these last over-wintered here many years ago. It is unusual for birds to call in mid-winter - say from late October until late-February. Needless to say it is my latest-ever record in any year.
- A female Bullfinch seen: a species I do not see very often here.

Birds noted flying over / near here:
[The local Wood Pigeons and Jackdaws not included]
- >50 Greylag Geese: presumed en route to Middle Pool
- 3 Cormorants: together
- 1 Lesser Black-backed Gull: adult

Counts from the water:
- 2 Mute Swan: as usual
- 1 Greylag Goose
- *129 Canada Geese
- 15 (11♂) Mallard
- 8 (3♂) Tufted Duck
- 2 (1♂) Goosander again
- 2 Great Crested Grebes
- 2 Moorhens
- 16 Coots
- 12 Black-headed Gulls only
- 1 Lesser Black-backed Gull: adult, briefly
- 2 Herring Gulls: adults briefly, together

Two Canada Geese on noisy departure over the ice.

Somebody has provided food on a fence post near the Blue Pig. This Robin has found it.

It is too late for a Christmas Robin but snow on the post would have been good.

Its best side?

Trench Middle Pool: 11:10 – 11:40

(41st visit of the year)

c.30% ice

Bird notes:
- A Pink-footed Goose found amongst the mass of Greylag Geese. I last saw this species here in January when up to four birds were present, usually with Greylags.
- Many of the Greylags flew over Trench Lock en route here and more arrived while I was walking around. Some birds were already inside the island so the total number is likely higher than those I counted.
- There were possibly also more Canada Geese and Coots lurking inside the island. Space on the open water was rather limited.

Birds noted flying over / near here:
None

Counts from the water:
- 2 Mute Swans
- *1 Pink-footed Goose
- *>125 Greylag Geese
- 37 Canada Geese
- 1 all-white feral goose
- 25 (17♂) Mallard
- 22 (13♂) Tufted Duck
- 3 (2♂) Goosander
- 1 Grey Heron again
- 1 Great Crested Grebe
- 9 Moorhens
- 36 Coots
- *>150 Black-headed Gulls
- 3 Lesser Black-backed Gulls

The Pink-footed Goose found here, usually with the Greylags but here in its own. Obviously the pink feet are not visible. Identify by the white-edges to the blue-grey back feathers and the pink mark on a rather short bill.

The pink on the bill often shows as a band, as here, though it can be more smudgy.

It was already packed with Greylag Geese when I arrived. Here another 24 about to join them.

Coming in for ....

 ... what might be termed 'splash-down'.

As at The Flash there were Black-headed Gulls standing on the ice.
