18 Dec 19

Trench Lock Pool only

Trench Lock Pool:  14:55 – 16:00

8.0°C:  Lowering overcast with rain from 15:50. Increasing SE breeze. Good visibility.

[Sunrise: 08:17 GMT]

Morning fog nixed any early visits. A check of the gull roost at Trench Lock after an end of year lunch with friends.

Trench Lock Pool:  14:55 – 16:00

(54th visit of the year)

c.10% thin ice remained

Notes from here:
- The Sparrowhawk was the reason for the sudden appearance of c.70 Jackdaws over.
- At least 68 Wood Pigeons seen heading off N singly – presumably to a roost.
- c.25 Starlings flew E low over the water at 16:00 when very dark. If they were heading to the big roost at Aqualate Mere then they would have been too late to take part in the murmuration.

Gulls:
- Black-headed Gulls continued to arrive until c.15:50. No arrival thereafter. The Sparrowhawk caused the whole group to take to the air and some may have moved off towards Middle Pool. The final total of c.850 was the count of birds remaining as I was preparing to leave.
- Most of the large gulls tended to stay for only a short period of time before moving off S. Just six Lesser Black-backed and two Herring Gulls remained when I left. A few more flew straight over.
- Two ‘dark backed’ Herring-type gulls were on the water briefly. One almost certainly the Yellow-legged Gull seen yesterday and the other quite possibly the potential Caspian Gull also seen yesterday. Much too dark to get any photographs.

Birds noted flying over / near here:
- 1 Sparrowhawk (twice)
- 8 Lesser Black-backed Gulls
- >68 Wood Pigeons
- c.70 Jackdaws
- c.25 Starlings

Counts from the water:

- 9 (3♂) Tufted Duck
- 7 (5♂) Goosander
- 3 Little Grebes
- 5 Great Crested Grebes again
- 2 Moorhens
- [Coots not counted]
- c.130 -> c.850 Black-headed Gulls
- >15 Lesser Black-backed Gulls (see notes)
- >8 Herring Gulls (see notes)
- 1 Yellow-legged Gull
- 1 possible Caspian Gull
