Priorslee Lake, The Flash

12.0°C > 15.5°C: Some mist to start with variable cloud. Light WSW wind after calm start again. Very good visibility.

Sunrise: 05:24 BST

Best today was a Green Woodpecker calling at The Flash – my first record here for several years. It became my 67th species at The Flash in 2017

Priorslee Lake: 04:35 – 06:10 // 07:00 – 08:25

(87th visit of the year)

One of the dog-walkers report an ‘owl with a flat face’ – so presumably a Barn Owl – over the playing field alongside Teece Drive late last evening

Talking of this field: I was also told that the Holy Trinity Academy have informed the council that they no longer wish to use the facility and have handed back their share of the lease. It is presumed that as the field is not fenced and is used by dog-walkers, not all of whom are punctilious about clearing up, there are health and safety issues. The council plan to use it as two junior football pitches – as there are no changing facilities there is limited scope for its wider use

A consequence of this is some positive news of a community-led plan, in conjunction with the Woodland Trust, to plant several hundred trees to replace those that were unnecessarily felled ahead the building work. There is also an outstanding requirement for the council to plant trees in a smaller area where felling was done without proper authorisation

It will take some years for any trees to have any significant wildlife benefit but it is welcome news

Notes from today:
- largest movement of geese since the breeding season. Most of these birds seemed to originate from ‘beyond’ The Flash – Trench area?
- cannot explain the variability in Coot numbers counted
- just 1 Common Sandpiper today
- two Common Terns again
- many fewer Black-headed Gulls than in recent days
- the 3 Lesser Black-backed Gulls likely a family party: an adult a two juveniles
- no Swifts: likely most have now left us until next May
- at least 2 Kingfishers today: being very noisy. Fledged family? Not seen to perch to enable me to check the age of the birds
- today the first Jackdaws of the week
and
- a Common Marbled Carpet moth on one of the lamps this morning
- a caddis fly sp. was also on the same lamp: possibly Oecetis ochracea
- just 2 pipistrelle-type bats seen again
- the usual Pearl Veneer (Agriphila straminella) grass moths flushed
- at least 1 Brown Hawker dragonfly
- a Grey Squirrel [or North America Gray Tree Rats, as I prefer to call them] eating the Hazel nuts already
- the Knotgrass (Polygonum aviculare) is no more – the vegetation growing under the fence around the Holy Trinity Academy has been ‘treated’ with weed-killer

On with the bird totals

Birds noted flying over the lake:
- 66 Greylag Geese (12 groups): 65 of these outbound
- 151 Canada Geese (18 groups): 135 of these outbound
- 3 Lesser Black-backed Gulls
- 3 Stock Doves
- 30 Wood Pigeons
- 8 Jackdaws
- 3 Rooks
- 32 Starlings
- 4 Pied Wagtails
- 1 Linnet
Hirundine etc. seen
- >9 House Martins

Warblers counts: number in brackets = singing birds
- 8 (2) Chiffchaffs
- 8 (0) Blackcaps
- 1 (0) Garden Warbler
- 3 (0) Common Whitethroats
- 8 (1) Reed Warblers

The counts from the lake area
- 2 + 3 Mute Swans
- 2 Canada Geese again
- 19 (?♂) Mallard
- 3 (0♂) Tufted Ducks
- 1 Grey Heron again
- 7 + 6 (2 broods) Great Crested Grebes remain
- 4 + 3 (3 broods) Moorhens
- 47 + 16 (14 broods) Coots
- 1 Common Sandpiper
- 2 Common Terns
- >45 (>11 juveniles) Black-headed Gulls

Not much of a sunrise today.

Talk about opportunistic. This juvenile Chiffchaff – the greenish cast on the back contrasting with the grey wings tells us it is a juvenile – was feeding on spiders and trapped insects in the security fence around the Holy Trinity Academy.

Here we can glimpse the yellowish wash on the flanks. A juvenile Willow Warbler would like very yellow in comparison.

The warbler was rather unhelpful in staying buried though in fact its sluggish behaviour also provided a clue. It is a Garden Warbler – the warbler without any real plumage features. It is a rather stout bird with a relatively thick and all-black bill, both features supporting Garden Warbler. The pale edges to the wing feathers suggest this is a juvenile – adults should not have moulted their wing feathers yet.

This can be a pitfall if you do not hear it and / or see its companions. It is a juvenile Goldfinch with the bold marks in the wing the easiest plumage ID. These birds will not acquire the red face of adults until well in to October or even November.

The Common Marbled Carpet moth was found on one of the street lamps. A very variable species and not too easy to separate from Dark Marbled Carpet. Here the projection at outer edge of the cross-band seems not pointed enough to be that species.

This caddis fly sp. was on the same lamp as the moth. I think it may be Oecetis ochracea, noted as having exceptionally long antennae. The habitat and date support the ID, but ....

Between the lake and The Flash alongside the path
- adult with 3 juvenile Moorhens seen alongside the upper pool
- 1 Chiffchaff heard calling here again

------------------------------------------------------------------------------------------------------

The Flash: 06:20 – 06:55

(68th visit of the year)

Notes from here
- Swans with cygnets all present today
- the 5 Mallard ducklings also seen. And an influx of Mallard contained an usual high percentage of ducks

Birds noted flying over
None

Hirundine etc. noted
None again

Warblers noted
- 2 (0) Chiffchaffs

The counts from the water
- 2 + 4 Mute Swans
- 6 Greylag Geese
- 44 Canada Geese
- 1 white feral goose
- 23 (13♂) + 5 (1 brood) Mallard
- 3 (0♂) Tufted Ducks
- 1 Grey Heron
- 2 + 3 (1 brood) Great Crested Grebes again
- 4 Moorhens
- 11 + 5 (5? broods) Coots

Who has been eating the fish? When I showed the photo to the fishermen they suggested Brown Rat (Rattus norvegicus) as the most likely culprit. Otters just eat the bits they find tasty; and a fox would make more of a mess of the structure. Having seen rats here this week it is probably a good call.

29 Jul 17

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

11.5°C > 14.0°C: Clear start with some mist; clouded later. Light SW wind after calm start. Excellent visibility.

Sunrise: 05:23 BST

Priorslee Lake: 04:35 – 06:00 // 06:50 – 08:20

(86th visit of the year)

Best here today
- 4 Common Sandpipers this morning – multiples are unusual on Autumn passage
- 1 Kestrel flew high E at 07:45: only my 2nd record of this species here this year

Other notes from today:
- much better proportion of juvenile Black-headed Gulls (c.30 out of c.170)
- a single Swift at 05:05 briefly; 2 powered W 06:55; then 14 to NE of dam feeding with House Martins after 07:40
- amazingly the first Rooks of the week
and
- 4 pipistrelle-type bats seen again
- very few Pearl Veneer (Agriphila straminella) grass moths flushed from very wet grass
- Volucella pellucens (Pellucid Fly) hoverfly the only insect on the lamps this morning

On with the bird totals

- >170 (>30 juvenile) Black-headed Gulls
- 3 Lesser Black-backed Gulls

Mist rising.

This juvenile Black-headed Gull is showing off its wing-pattern as it checks out what is on the surface of the water. I could not tell whether it was a dead fish or debris – the latter I suspect as the gulls left it alone.

Another mid-hover view.

These 3 Lesser Black-backed Gulls dropped in for a while: the two birds on the left look like 2nd summer birds about to start moult into 3rd winter plumage – the middle bird looks especially worn and faded. I would have expected their eyes to look paler though their heads are unspotted so I think my ageing is correct.

A Song Thrush rooting about in the grass.

The Volucella pellucens (Pellucid Fly) hoverfly sitting on the ‘numbers’ of a street-lamp. Note the wear in the wings.

Between the lake and The Flash alongside the path

------------------------------------------------------------------------------------------------------

Trench Lock Pool: 08:25 – 08:40 // 09:20 – 09:45

(22nd visit of the year)

Notes from here
- one of the original cygnets ‘missing’ (but then so was one of the adults)
- Mallard numbers usually increase at this time of year but 29 is a good count
- unexpectedly high number of Tufted Ducks: just 1 drake – c.f. Middle Pool totals below
- Kingfisher here
- House Martins included juveniles
- 2 Bullfinches: a new species for me here this year
and on the wall of the Blue Pig
- 2 Red Underwing moths: new for me this year
see below for new species of flower

Birds noted flying over here
- 2 Canada Geese
- 1 Grey Heron

- Tansy (Tanacetum vulgare)
- Greater Willowherb (Epilobium hirsutum)
- Common (or Black) Knapweed (Centaurea nigra)
- Common Hogweed (Heracleum sphondylium)

The tight flower-heads of Tansy (Tanacetum vulgare).

High up on the wall of the Blue Pig pub, outside lights still burning, I found two of these moths – they are Red Underwing moths.

This specimen at not quite so helpful angle though we also see a Chironomus plumosus (plumed midge sp.).

(Ed Wilson)

------------------------------------------------------------------------------------------------------

Trench Middle Pool: 08:45 – 09:15

(18th visit of the year)

Notes
- as far as I can remember this is the first time I have known Mute Swans to breed here
- not sure of the number of broods of Canada Geese were involved – indeed some birds hard to distinguish from adults
- surprising number of Tufted Duck – and almost all drakes in contrast with Trench Lock Pool
- the Grey Heron was my first of the year here
- 4 Great Crested Grebes juveniles is a good brood size
- the broods of Coots were of all ages – some almost fledged whilst at least 2 broods very new
- a Racing Pigeon – it was wearing rings on both legs – was amongst the geese and was hard to avoid treading on at times: also new for me here this year

Birds noted flying over here
None

Warblers noted
None

The counts from the water
- 2 + 6 Mute Swans
- 5 Greylag Geese
- 69 Canada Geese: (>17 goslings?)
- 27 (25♂) Mallard [also 2 ‘feral’ birds]
- 14 (12♂) Tufted Duck
- 1 Grey Heron
- 2 + 4 (1 brood) Great Crested Grebes
- 4 + 1 (1 brood) Moorhens
- 13 + 12 (8 broods) Coots

Plants not checked here

The Swans with their cygnets: my first record of breeding here.

This extremely ‘leggy’ Canada Goose gosling seemed to be the only one of its brood – unless it is just a weakling and not developing properly.

Here an adult stands over two almost full-grown goslings drinking from a rainwater pool. The edges of the white chin-strap are slightly ‘fuzzy’ otherwise they would be hard to separate from adult. Very slightly smaller but then adults vary in size, the females typically smaller.

Two of the 4 Great Crested Grebe chicks with an adult. To get a full brood of four to this stage is not common.

The Racing Pigeon that seemed determined to get trodden on. Seems to be an English bird from the cross of St. George on the ring.

The web tells me EFTU means English Flying Tippler Union. Apparently tipplers are a variety of domestic pigeon bred mainly for flying.

Priorslee Lake
1 Common Terns
(Ed Wilson)

28 Jul 17

Priorslee Lake and The Flash

12.5°C > 15.0°C: Variable cloud with passing light rain showers. Light / moderate SW wind. Very good visibility

Sunrise: 05:22 BST

Priorslee Lake: 04:30 – 06:05 // 06:55 – 08:25

(85th visit of the year)

Notes from today:
- the two Grey Herons were, unusually, happy with each other’s company
- another adult Great Crested Grebes today. One of the two well-grown juveniles was seen flying today and these two spent only a limited time together
- now 2 Common Sandpipers
- no sign of the Common Terns today
- the Sand Martin seemed to fly out of the NW reed bed – had it been roosting here?
- party of c.26 House Martins high over estate to NW of lake
- Kingfisher seen several times and on at least one occasion carrying food
- juvenile Grey Wagtail seen again
and
- 4 pipistrelle-type bats seen
- a Leiobunum rotundum (a harvestman) on the lamps
- a few Pearl Veneer (Agriphila straminella) grass moths flushed
- possible ID for a dagger fly as Empis nigritarsis
- Episyrphus balteatus (Marmalade hoverfly) the only hoverfly logged
- Water Mint (Mentha aquatica) flowers seen for first time this morning – the smell of the plant has been obvious for some days

On with the bird totals

Birds noted flying over the lake:
- 45 Greylag Geese (1 group) outbound
- 57 Canada Geese (5 groups) all outbound
- 3 Lesser Black-backed Gulls
- 29 Wood Pigeons

Hirundine etc. seen
- 1 Sand Martin (see notes)
- 3 Barn Swallows
- c.26 House Martins

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

The counts from the lake area
- 2 + 3 Mute Swans
- 1 Canada Goose
- 25 (?♂) Mallard
- 4 (0♂) Tufted Ducks
- 2 Grey Herons
- 7 + 6 (2 broods) Great Crested Grebes (see notes)
- 7 + 2 (2 broods) Moorhens
- 39 + 9 (7 broods) Coots
- 2 Common Sandpipers
- >100 (>7 juvenile) Black-headed Gulls

The sunrise today: looked a bit threatening as well it might with showers on the way ahead of rain in the evening.

Another view complete with many black dots – these are all Black-headed Gulls arriving.

This Grey Heron – standing behind one of the boating platforms – has just had a good shake and it now about to rearrange its feathers.

The Great Crested Grebe family growing up.

One of the Common Sandpipers present: this is an adult – a juvenile would show more extensive pale fringes to its feathers.


A Black-headed Gull showing extensive wing-moult. As gulls moult from the first (inner primary) we see that only the outer primaries remain to be replaced, all the other primaries are regrowing. The secondaries moult the ‘other’ way – from the outer to the inner – hence the ‘gap’ mid-wing.

A juvenile Common Whitethroat – note the white on the mantle. Otherwise juveniles and immatures are hard to separate from females (and many males!).

Another view: most males would show a more distinct eye-ring and a reddish iris.

After several at The Flash yesterday here is a Leiobunum rotundum (a harvestman) at the lake – at least I think it is: the palps look rather longer than any image I can find on the web.

This is a Tetragnatha spider: the exact species requires detailed examination under a microscope: likely Tetragnatha montana.

This seems to be the dagger fly Empis nigritarsis. I am somewhat perplexed though that the body looks ‘waisted’ like a wasp sp. so this must be regarded as a provisional ID.

This is Greater (or Large) Bird's-foot-trefoil (Lotus pedunculatus). My first record of this plant here.

Another view of the same plant.

These are the flowers of Water Mint (Mentha aquatica)

Between the lake and The Flash alongside the path
- adult and juvenile Moorhens alongside the upper pool
- no warblers heard here today

Priorslee Lake and The Flash

11.0°C > 12.5°C: Areas of medium cloud with lower cloud and light rain shower later. Light SW wind. Very good visibility

Sunrise: 05:20 BST

Highlight today was my first-ever Fox at The Flash – and a very scruffy individual it was too. My attention was drawn to it by a pair of Crows making a lot of fuss as they followed it across the grass at the N end. Amazingly the 3 Greylag and 16 Canada Geese stood transfixed on the grass and watched the Fox go by

Priorslee Lake: 04:30 – 05:55 // 06:45 – 08:05

(84th visit of the year)

Notes from today:
- the additional pair(?) of adult Great Crested Grebes were present again: I suspect they are early-brood juveniles as they have very few head plumes, though they have lost the head-stripes
- the Common Sandpiper seen pre-dawn only
- the (same?) pair of Common Terns arrived from the E very noisily at 07:27
- group of at least 130 Black-headed Gulls swooped in at 05:15 to join the c.45 already present. Proportion of juveniles remains low
- a relatively new brood of Great Tits was a surprise: however unlike Blue Tits this species is sometimes double-brooded; so a 2nd brood
- one of the two parties of Long-tailed Tits contained at least 13 birds
- at least 3 juvenile Goldfinches today – my first this year
and
- several Tetragnatha web spider on the lamps again
- at least 6 Pipistrelle-type bat sps. along the N side pre-dawn: my highest-ever count
- first Yarrow (Achillea millefolium) of the year noted
- Red Valerian (Valeriana officinalis) in bloom again along the base of the dam after having been strimmed earlier

On with the bird totals

Birds noted flying over the lake:
- 11 Greylag Geese (2 groups) all outbound
- 59 Canada Geese (8 groups) all outbound
- 39 Wood Pigeons

Hirundine etc. seen
- 1 Swift at 05:50 only

Warblers counts: number in brackets = singing birds
- 4 (1) Chiffchaffs
- 3 (0) Blackcaps
- 1 (0) Common Whitethroat again
- 5 (2) Reed Warblers

The counts from the lake area
- 2 + 3 Mute Swans
- 4 Canada Geese again
- 28 (?♂) Mallard
- 3 (1♂) Tufted Ducks
- 6 + 6 (2 broods) Great Crested Grebes
- 4 Moorhens
- 34 + 8 (7 broods) Coots
- 1 Common Sandpiper yet again
- 2 Common Terms arrived at 07:27
- c.175 (>6 juveniles) Black-headed Gulls

All the signs of a repeat of yesterday’s “shepherds’ warning”

Eventually even better.

At its best.

And long after the red had faded still an interesting sky.

Mum (I assume) Great Crested Grebe with a full load (there are 4 if you look really hard).

The young beginning to take note of their surroundings, peering out.

A shot of the Common Tern in flight today (taken in dull conditions and enlarged somewhat so some ‘noise’ in the background).

And the other bird just about to lift off from a buoy.

A number of different immature Black-headed Gulls. When they first fledge they are very ginger-brown but this soon fades and they moult some feathers – here we see extensive pearl-gray in the greater coverts.

This bird has more extensive retained ginger-brown on the nape and a few 1st winter pearl-grey feathers on mantle and scapulars.

Another bird with extensive ginger-brown on the nape but with no new feathers on the mantle.

A juvenile Great Tit showing rather indistinct markings and yellowish tone to what would be much whiter areas in an adult.

As a postscript to yesterday’s spiders here we see a male (at the top) with a female Tetragnatha web spider, probably T. montana (I hope you are viewing this after the watershed ...)”.

The small, flat and tight flower cluster and the feathery leaves identify this umbellifer as Yarrow (Achillea millefolium). My first this year.
Between the lake and The Flash alongside the path
- juvenile Moorhens calling from reeds in the upper pool
- Kingfisher flying through along the like of the Wesley Brook
- single Chiffchaff and Blackcap calling around the lower pool
