Trench Lock Pool: 09:50 – 10:15 // 10:50 – 10:55

Sunrise: 07:15 BST

Priorslee Lake: 06:10 – 09:00

(123rd visit of the year)

Bird notes:
- double-checked the party of Greylag Geese but was unable to ‘string’ a Pink-footed Goose amongst them
- Gadwall gone again
- some of the Tufted Duck seemed to have decamped to The Flash since yesterday
- 44 Wood Pigeons noted on the football field: seems I beat the dog-walkers this morning
- Jackdaw main passage this morning was just 16 birds skimming the fields below tree-height to the E
- in addition to the usual local / resident Carrion Crows a group of 4 flew high W and then presumably the same 4 flew high E a few minutes later
- only my 2nd log of Raven over here this year

Bird totals

Birds noted flying over or flying near the lake
- 11 Greylag Geese [1 party inbound]
- 1 Sparrowhawk
- 2 Common Buzzards
- 2 Lesser Black-backed Gulls once again
- 34 Wood Pigeons
- 22 Jackdaws
- 6 Rooks
- 4 Carrion Crows
- 1 Raven
- 4 Pied Wagtails
- 1 Siskin again

Warblers noted:
- 2 Chiffchaffs

The counts from the lake area
- 2 + 3 (1 brood) Mute Swans
- 7 (5♂) Mallards
- 50 (7♂) Tufted Ducks
- 2 Little Grebes
- 4 + 1 (1 brood) Great Crested Grebes still
- 11 Moorhens
- 133 Coots again
- 86 Black-headed Gulls
- 1 Lesser Black-backed Gull again

And other notes
- my log today consisted of
- 2 Garden Spiders on the same lamp
- 1 fly sp. on a lamp
- >50 midges dancing around my head
- 4 fruits of Shaggy Inkcap / Lawyer's Wig (Coprinus comatus) fungus just inside the Holy Trinity Academy fence
- 1 Grey Squirrel

Breakfast this morning was a long-distance affair by the dedicated adult. It carried this fish almost the length of the lake and running the gauntlet of the ever-opportunistic Black-headed Gulls after a free meal before eventually catching up with junior.

3 of the 4 fruits of Shaggy Inkcap / Lawyer's Wig (Coprinus comatus) fungus just inside the Holy Trinity Academy fence. These are supposed to be good to eat when young but I would never recommend eating any wild mushroom.

The Flash: 09:05 – 09:40

(100th visit of the year)

Notes from here
- the hybrid goose was a different bird from the usual apparent Greylag x Canada cross and a noticeably small bird
- the Mallard were handily all gathered together taking advantage of proffered food. They were all spinning around and fighting and I managed to make a reasonable count of how many birds there might be; but checking the age / sex of each bird was impossible
- there are usually Goldfinches in and around here: today’s birds were in a tight group flying high over

Birds noted flying over or near to The Flash
- 7 Feral Pigeons again
- 3 Jackdaws
- 7 Goldfinches

Warblers noted
- 1 Chiffchaff

The counts from the water
- 2 + 3 Mute Swans again
- 15 Greylag Geese: 4 arrived
- 1 Greylag x Barnacle? Goose arrived
- 33 Canada Geese arrived
- 37 (?♂) Mallard
- 19 (3♂) Tufted Ducks
- 2 Grey Herons
- 1 + 1 (1 brood) Great Crested Grebes
- 3 Moorhens again
- 7 Coots
- 55 Black-headed Gulls

Another poor-light special of the rather different hybrid goose. The bill suggests Greylag. The face is a strange combination of both Canada and Barnacle. The marks on the back of the neck don’t match any wild goose. The size suggests that Barnacle genes are somewhere in the mix.

I last visited Trench in early April. These sites are best in winter for visiting ducks

Trench Lock Pool: 09:50 – 10:15 // 10:50 – 10:55

(14th visit of the year)

Another reason I stopped visiting Trench Lock Pool was the sheer number of fishermen and the consequent disturbance to the birds

I was subsequently told that there were problems here after The Canal and Rivers Trust, who operate (own?) the water, had introduced alien fish from another of their properties whilst that was maintained

I read on the web that KHV (Koi herpesvirus) has been confirmed here and as a result fishing has been banned

The water level is by far the lowest I can remember: the web tells me that the trust are doing some work and have lowered the level. Only a BT OpenReach van was present this morning

There was also no action at the small housing development by the Blue Pig pub. The gates were chained shut. All the equipment seemed to be present. One downside of this development is that the informal footpath that crossed the grass is now blocked and it is no longer possible to circumnavigate the pool

Bird notes from here
- all 16 Mute Swans were (near) adults. Seems there was no successful breeding here this year
- no Tufted Ducks was unusual: perhaps the low water means it is too shallow
- a Grey Wagtail here was my first of the year at this site

Birds noted flying over here [apart from the local Wood Pigeons and Jackdaws coming and going]
- 1 Sparrowhawk

Warblers noted: figure in brackets is singing birds
- 1 (1) Chiffchaffs again

The counts from the water
- 16 Mute Swans
- 37 Canada Geese
- 15 (8♂) Mallard
- 1 (1♂) ‘feralMallard still
- 1 (0♂) Shoveler
- no Tufted Ducks
- 2 Cormorants
- 1 Grey Heron
- 2 + 3 (1 brood) Great Crested Grebes
- 8 Moorhens
- 159 Coots
- 34 Black-headed Gulls
- 2 Lesser Black-backed Gulls

No fishing as a result of KHV (Koi herpesvirus). [CEFAS = Centre for Environment, Fisheries and Aquaculture Science: TAA = Telford Angling Association].

From the ramp by the Blue Pig looking north at the low water-level.

And looking E.

Trench Middle Pool: 10:20 – 10:45

(13th visit of the year)

Notes from here
- just 2 cygnets from this year
- no sign of any immature Great Crested Grebes. Possible that an early brood could have fledged and left
and
- the usual growth of some very large fungus, perhaps Wood Blewit (Lepista nuda)

Birds noted flying over here
None

The counts from the water
- 2 + 2 Mute Swans
- no Greylag Geese
- 39 Canada Geese
- 26 (20♂) Mallard
- 6 (1♂) Tufted Duck
- 1 Grey Heron
- 2 Great Crested Grebes
- 9 Moorhens
- 25 Coots
- 8 Black-headed Gulls

One of the >10 large fungus pushing up through the leaf litter here – as they do every autumn. The blackberry leaves give it some scale.

Another trio. The leaf-litter is firmly attached to the top of the fungus, probably because they are sticky when they first emerge. So I was not able to do any ‘gardening’ to get a better view of the fruiting bodies. I suspect they are Wood Blewit (Lepista nuda). Another species that is supposed to be good to eat. I wouldn't!
