Priorslee Lake, The Flash, Trench Lock Pool and Trench Middle Pool [in an unusual order]

Priorslee Lake:  07:00 – 09:30
The Flash:  11:05 – 11:45
Trench Lock Pool:  09:40 – 09:55 // 10:35 – 11:05
Trench Middle Pool:  10:00 – 10:30

4.0°C > 5.0°C:  Very low cloud soon breaking up with clear spells. Then after 09:15 fogged in at Priorslee – so off to Trench where clear. Stayed clear. Light / variable, mainly S breeze. Moderate / good visibility, poor at Priorslee for a while.

Sunrise: 08:22 GMT still

Best of the day was the Pink-footed Goose that arrived at Trench Middle Pool (q.v.)

Priorslee Lake:  07:00 – 09:30

(299th visit of the year)

Bird notes:
- The fifth Mute Swan cygnet again went for a fly on its own.
- Two Canada Geese on the water when I arrived. Another two flew in c.08:00. All stayed until 09:20 when two left.
- Another challenging day with the Jackdaws and Rooks. >1000 birds streaming past together at 07:38 in multiple mixed groups. Several small groups later.
- A strange morning with Wood Pigeons. Firstly nine birds flew high N in a very loose group. Then 13 flew high E. 22 more flew E before two groups of 68 and 21 respectively flew high W, the larger group containing a Stock Dove. A few singles over as well. Finally 43 were noted descending in to trees around the ‘football’ field, just as I was about to leave and as it fogged in. None of these movements seemed to be initiated by the bird scarers in the fields to the E.
- Five singing Song Thrushes.
- I initially assumed the two Pied Wagtails overhead were making their way to their usual E-end lay-by feast. They were not there.
- Reed Buntings left the roost in three small groups, with the final three at 08:25 – later than I have stayed to check on previous days. Strangely two birds were seen to fly in to the roost area from nearby prior to any birds departing.

Very few large gulls came and went

The bank of fog in the distance.

A drake Gadwall. After the magnificent Pintail this is my second-favourite duck.

The Flash:  11:05 – 11:45

(284th visit of the year)

Some unusual disturbance from one of the fishermen today who appeared to be throwing a weighty object on a rope in to the water and pulling it out. I know nothing about fishing but apart from possibly stunning some accidentally I have no idea what he was doing. Birds were staying well away.

Bird notes from here:
- Usual problem with Great Crested Grebes. Certainly two together. One seen in a different location but then I could relocate neither of the others.
- Lower number of Pochard.

- 3 Mute Swans as ever

- 10 (0♂) Goosander: departed
- 1 Grey Heron yet again
- 3? Great Crested Grebes
- 1 Moorhen again
- 12 Coots again
- 27 Black-headed Gulls only: and 15 of these left as I arrived
- 1 Lesser Black-backed Gull: leaving as I arrived
- 1 Kingfisher seen on the island

Other sightings:
- c.10 Muscid sp. flies on the Ivy bank

A slightly better shot of the Kingfisher lurking on the island.

Bird notes from here:
- Bright and low sun prevented me looking in to the vegetation where the Little Grebes often hide.

The Canada Goose formation team comes in to land.

Touch down!

This group floating in seem rather reluctant to lower their undercarriage.

A drake Goosander, its bill ploughing through the water.

Same bird now in the sun.

And now preening. Note in particular the serrations on the bill, used for gripping fish. This feature gives this family of ducks the generic name of ‘sawbills’.

Today’s gull lesson. The underwing pattern on this adult winter Lesser Black-backed Gull shows a dusky trailing edge apart from the inner primaries. Note the heavily-streaked head on this bird. Also that there is no black on the upper mandible, just a hint alongside red spot on the lower mandible.

Trench Middle Pool:  10:00 – 10:30

(57th visit of the year)

The arriving Pink-footed Goose was a surprise. However not new here in 2019 – I logged one on 04 March. I noted today’s bird as I scanned the geese just after they landed and managed a quick confirmatory shot before it joined all the others behind the island. I could not re-find the bird on the water when I walked around to view the other side: many of the Greylag Geese had climbed on to the island and could not be seen. It must have done so too. The photos I took of the geese arriving shows this bird somewhat better.

Notes from here:
- So why did the gulls all get up and leave? They swirled around for a while but never re-settled.

Birds noted flying over / near here.
None

Counts from the water:
- 1 Pink-footed Goose: arrived with Greylags
- 136 Greylag Geese: 120 of these arrived
- 19 Canada Geese
- 1 all-white feral Goose-type as usual

- 1 Grey Heron
- 1 Great Crested Grebe again
- 14 Moorhens
- 42 Coots
- 18 Black-headed Gulls: all departed as I arrived
- 1 Herring Gulls: departed as I arrived

The group of Greylag Geese arriving. Note the aerobatics being used to lose height with a bird at the top right upside-down. If you enlarge the photo look carefully at the second bird from the left along the bottom: no orange bill.

Here the unusual bird is right in the middle. Note the black neck and upper breast.

... and bottom right here ....

... and bottom left here. We can even see the pink feet on this bird – a Pink-footed Goose.
