Priorslee Lake and The Flash

15.5°C > 12.5°C: Clouding up from W with occasional mainly light drizzle and low cloud later. Light SE at first, then light / moderate NW. Very good visibility to start becoming moderate, even poor, in drizzle

Sunrise: 06:14 BST

First day back after three weeks in Brazil’s Amazon jungles was a shock to the system

Priorslee Lake: 05:35 – 06:50 // 07:40 – 08:45

(92nd visit of the year)

The work on and around the dam is now complete with several access covers on and around the dam

For some reason the Council or its contractors have seen fit to flail some of the hedges around the football field, removing hips and haws that would have been food for winter thrushes later in the year

Notes from today:
- probably more geese than I logged: many of the parties very distant both to the N and S with some barely above tree-height
- one pair of Great Crested Grebes still with 4 now well-grown juveniles; another pair with 3 quite new juveniles; 2 more pairs not showing any inclination to nest; and a fledged juvenile
- many Black-headed Gulls flew overhead directly from roost (Middle Pool?) to the fields to the E. These may have been among the c.175 birds seen on the lake later – there were <60 earlier
- >95 Lesser Black-backed Gulls flew SE mainly to the NE early with a few of these stopping off at the lake for a while. Later >20 large gulls dropped in to the lake for a while
- single Jackdaw and Rook this morning: perhaps I arrived too late for the overhead roost dispersal?
- for the first tine this year there were no Song Thrushes singing today
- Robins now back in full song – 36 logged this morning. A month ago I was logging as few as 12
- no sight or sound of any Reed Warblers: they have likely left, but is always difficult to prove the absence of anything
and
- two moths on the lamps: a Six-stripe Rustic which is a new species for me; and my first Common Grass-veneer (Agriphila tristella) of the year
- single Syrphus sp. hoverfly seen, not well-enough to specifically ID
- probably too late arriving to see any pipistrelle-type bats
- lots of Common Ragwort (Jacobaea vulgaris) on the dam – rather late this year?

On with the bird totals

Birds noted flying over the lake:
- 4 Greylag Geese: 4 (1 group) outbound
- 138 Canada Geese: 138 (11 groups) outbound
- 1 Cormorant
- >88 Black-headed Gulls
- >83 Lesser Black-backed Gulls
- 9 Wood Pigeons
- 1 Jackdaw
- 1 Rook
- 3 Pied Wagtails

Hirundine etc. seen or heard today
- c.40 House Martins

Warblers counts: number in brackets = singing birds
- 6 (1) Chiffchaffs
- 4 (0) Blackcaps

The counts from the lake area
- 2 + 3 Mute Swans
- 23 (?♂) Mallard
- 8 + 8 (3 broods) Great Crested Grebes
- 1 Grey Heron
- 4 + 4 Moorhens
- 66 (>3 juveniles) Coots
- c.175 Black-headed Gulls
- 26 Lesser Black-backed Gulls
- 2 Herring Gulls
- 1 Kingfisher

Spent a long while looking hard at the gull in the middle here. It looked rather small for either Lesser Black-backed or Herring Gulls – compare with the adult Lesser Black-backed Gull behind. The paleness of the plumage suggests Herring rather than Lesser Black-back though that species is generally the larger of the two. The bill is all dark and too heavy for Common Gull.

I managed to sneak a closer view without flushing the birds and it does appear it is ‘just’ a small juvenile Herring Gull.

A new moth for me: a Six-stripe Rustic.

A very common grass moth – Common Grass-veneer (Agriphila tristella): my first this year.

Notes from here
- higher than expected number of Tufted Ducks
- were the Coots just hiding or have some left?
- most of the gulls flew off while I was present – to the lake?
- many House Martins heard high overhead as I arrived but I could not locate them: possibly the same party of c.40 birds seen over W end of the lake a few minutes earlier
