Priorslee Lake and The Flash

Priorslee Lake: 05:25 – 07:00 // 07:55 – 09:35
The Flash: 07:05 – 07:50

12°C > 15°C: Cloudy with very few breaks. Cleared to high cloud only after 08:00. Then clouded again after 09:00. Light W wind. Very good visibility

Sunrise: 06:14 BST

Priorslee Lake: 05:25 – 07:00 // 07:55 – 09:35

(107th visit of the year)

Bird notes:
- unusually the two Grey Herons were content to occupy adjacent sailing club launch platforms – they are normally very territorial. One was a juvenile so perhaps the other was a tolerant parent
- Black-headed Gulls in typical small numbers early. By the time I returned from The Flash there I counted 196, some of which were leaving to the fields to the E. Some 20 minutes later a big influx back from the fields (along with a Lesser Black-backed Gulls) saw at least 250 on the lake. They flew off and back several more times. Each time a few Lesser Black-backs came in – these were obviously different birds so perhaps some of the Black-headed Gulls wee also different. Largest count of the season so far
- c.30 House Martins seen high over the estate at 07:00 again. Then 26 were seen high to the N at 08:45, apparently heading SE. Very few over the estate later

Bird totals

- no different plants noted
- mammals seen
- 2 Grey Squirrels

This Common Buzzard, carrying food, was being given a hard time by a Carrion Crow.

And here it is calling while being chased but what I assume is one of its off-spring. At this range, and hence magnification, we cannot really identify the prey.

Just a few of this morning’s large (>250) party of Black-headed Gulls.

Joined here by three (one adult and 2 1st year) Lesser Black-backed Gulls.

This is an adult Lesser Black-backed Gulls in moult. We see a few missing inner primaries: also some missing upperwing coverts that allow us to see the bases of some of the secondaries as white streaks.

A Small White butterfly from underneath. Lacks the ‘lines’ of Green-veined White and too small for Large White. On Large White the marks on the wing tip would be darker (though this can wear) and be more extensive.

And the top-side view of a different specimen.

This is a squash bug species: more elongated than shield bugs. This is a Dock Bug (Coreus marginatus).

Priorslee Lake and The Flash

Priorslee Lake: 05:30 – 07:00 // 07:50 – 09:40
The Flash: 07:05 – 07:45

11°C > 15°C: Clear but with increasing high cloud. Calm start with mist over the water: light SW breeze later. Very good visibility

Sunrise: 06:12 BST

Highlight was a Yellow Wagtail that flew S over the lake at 08:00. My first here this year – moving my lake year total to 94 bird species. This species is most often seen or heard on passage in Spring. It breeds in small numbers on farmland locally – depending which crops are grown where

Close behind were the two Ravens tumbling overhead the Flash. My 67th bird species at The Flash this year. A species I have yet to see over the lake this year

Priorslee Lake: 05:30 – 07:00 // 07:50 – 09:40

(106th visit of the year)

Bird notes:
- the juvenile Great Crested Grebe from the second brood was back in the water and begging
- no obvious reason for lower number of Moorhens logged
- no idea why so few Black-headed Gulls stopped off
- c.30 House Martins seen high over the estate at 07:00 and 07:55. Occasional small groups seen from 06:10 and throughout may have been some of these or may have been other birds moving through

Bird totals

birds noted flying over or flying near the lake:
- 23 Canada Geese [23 (1 group) outbound only]
- 1 (?♂) Mallard
- 1 Common Buzzard
- 64 Black-headed Gulls
- 2 Lesser Black-backed Gulls
- 4 Stock Doves (singles)
- 91 Wood Pigeons
- 1 Collared Dove
- 4 Jackdaws again
- 1 Yellow Wagtail
- 1 Pied Wagtail

Hirundines etc. noted
- 1 Barn Swallow
- >30 House Martins

Warblers noted:
- 11 (1) Chiffchaffs
- 7 Blackcaps

The counts from the lake area
- 2 + 3 (1 brood) Mute Swans as usual
- 12 (?♂) Mallards
- 4 + 4 (2 broods) Great Crested Grebes
- 6 + 5 (? broods) Moorhens
- 92 (near) adult + 8 dependent juvenile Coots again
- 28 (? juveniles) Black-headed Gulls

And other notes
- butterflies
- 4 Speckled Wood
- moths on the lamps
- 4 Agriphila tristella (Common Grass-veneer)
- no moths identified elsewhere: why do I not flush any grass moths?
- damselflies / dragonflies
- 1 hawker sp. dragonfly
- hoverflies
- >4 Melanostoma scalare (Chequered Hoverfly)
- 2 Syrphus ribesii
- flies etc. identified
- a hairy Tachina fera fly
- many wasps again: none on the lamps today so perhaps not spider victims after all
- hatch of Mystacides longicornis (caddis flies) dancing around the water’s-edge
- beetles or bugs noted
- 1 Common Green Shieldbug (Palomena prasina)
- no spiders seen despite walking through many web-strands at first light
- no different plants noted
- mammals seen
- 1 Grey Squirrel

A while since I have been able to photograph the (almost) full moon. Sadly a thin veil of high cloud took the edge off the clarity.

The fine weather produced the first decent sunrise for a while.

Just visible on the left of this view is the small amount of mist over the water ....

 ... Better seen from ‘the other end’.

Not one from the Ricoh copse family: a fly-over Common Buzzard.

And making a lot of fuss about it too.

Two hoverflies for the price of one: on the left Syrphus ribesii; on the right Melanostoma scalare.

This is the fly Tachina fera – a very hairy fly with a broad black band down the otherwise orange body. Despite being a common and widespread species all across Europe, as far as Japan and in to North Africa, it has no vernacular name.
A Common Green Shieldbug (Palomena prasina).

The Flash: 07:05 – 07:45

(87th visit of the year)

Notes
- just scraped getting geese on the list when 2 Greylags arrived just as I was leaving
- the newest brood of Mallard seems to now comprise just 3 ducklings – or is this yet another late brood? They do seem very small
- just one obvious aggregation of more or less full grown Mallard ducklings (8 individuals). Many (near?) adults seen
- 3 different Coal Tit heard singing – usually 1 or 2 at best
and
- 3 Grey Squirrels

Birds noted flying over or near to The Flash
- 13 Feral Pigeons (4 groups)
- 8 Wood Pigeons
- 3 Jackdaws

Priorslee Lake and The Flash

Priorslee Lake: 05:30 – 07:00 // 07:40 – 09:25
The Flash: 07:05 – 07:35

13°C > 15°C: Cloudy with spells of mainly light drizzle. Moderate WSW wind, even fresh at first. Very good visibility, moderate in drizzle.

Sunrise: 06:11 BST

Highlight was another Hobby seen, this time over The Flash – my first record from The Flash itself and my 67th bird species of the year there

As a post-script to yesterday’s highlights
- I should have noted the Black Tern as an adult bird. One turned up at the West Midlands Bird Club reserve at Belvide Reservoir, just 10 miles to the E, at 09:15 yesterday. The same bird?
- one of the fishermen told me that the 5 Shelduck I noted in flight yesterday had briefly stopped off on the water. Obviously while I was amongst the trees on the N shore

Priorslee Lake: 05:30 – 07:00 // 07:40 – 09:25

(105th visit of the year)

Bird notes:
- where were all the geese: the very few I saw were about an hour later than usual
- the juvenile from the second brood of Great Crested Grebe was perhaps sheltering on its parent’s back. The third pair of Great Crested Grebes not located
- probable Sand Martin over the dam at 06:30
- 2 Barn Swallows flew S 06:40; then 5 to the lee of the dam / over N side trees c.08:25
- 39 House Martins counted high over 06:35. Then at least 50 high over 07:45 with several smaller groups seen later. How many birds involved?
- 1 Reed Warbler seen by the Wesley Brook footbridge; another singing quietly nearby. A late date for this species. I cannot recall ever having heard this species in song after breeding is complete

Bird totals

Birds noted flying over or flying near the lake:
- 14 Greylag Geese [9 (2 groups) outbound; 5 (1 group) inbound]
- 6 Canada Geese [6 (1 group) outbound only]
- 3 (?♂) Mallards
- 1 Sparrowhawk
- 1 Common Buzzards
- 13 Black-headed Gulls
- 5 Lesser Black-backed Gulls
- 8 Feral Pigeons (4 groups)
- 2 Stock Doves (singles)
- 58 Wood Pigeons
- 4 Jackdaws
- 2 Carrion Crows

Hirundines etc. noted
- 1 Sand Martin
- 7 Barn Swallows
- >>50 House Martins (see notes)

Warblers noted:
- 9 Chiffchaffs
- 4 Blackcaps
- 2 (1) Reed Warblers

The counts from the lake area
- 2 + 3 (1 brood) Mute Swans
- 14 (9♂) Mallards
- 1 Grey Heron
- 4 + 4? (2 broods) Great Crested Grebes (see notes)
- 7 + 8 (? broods) Moorhens

And other notes
- no butterflies
- moths on the lamps
- 1 Agriphila tristella (Common Grass-veneer)
- no moths identified elsewhere
- no damselflies / dragonflies
- hoverflies
- 1 Episyrphus balteatus (Marmalade Hoverfly)
- 1 Melanostoma scalare (Chequered Hoverfly)
- 1 Syrphus ribesii
- flies etc. identified
- 2 wasps sp. in the spider larder(?) on a lamp
- no beetles or bugs noted
- no spiders identified
- no different plants noted
- mammals seen
- 1 Brown Rat (Rattus norvegicus): first of year here
- 2 Grey Squirrels

The Common Buzzards were being very noisy today with two juveniles begging (howling?) for food and this adult sitting on one of the lamps in Teece Drive and calling back.

Another in my feather portfolio: this seems to be a under-feather of a Mute Swan.

This is another Syrphus ribesii hoverfly. Despite the cloud and drizzle a few convolvulus flowers were open and I managed three species of hoverfly in and around them.

These two wasps were in the same location on a lamp where I photographed a spider apparently tackling a wasp yesterday. Whether these two are now trapped and part of the spider’s larder is hard to say. They look unharmed but on the other hand why would two wasps be this close together pre-dawn.

The Flash: 07:05 – 07:35

(86th visit of the year)

Notes
- where were all the geese? ...
- ... for that matter where were most of the adult Mallard?...
- ... and where were the adult Great Crested Grebes?
- 7 of the Tufted Duck were together – perhaps the juveniles? None was an obvious drake

Birds noted flying over or near to The Flash
- 1 Common Buzzard
- 1 Hobby
- 7 Feral Pigeons again
- 2 Stock Doves
- 2 Wood Pigeons
- 2 Jackdaws

Hirundines etc. noted
None

Warblers noted
- 2 (1) Chiffchaffs
- 1 Blackcap: male seen

The counts from the water
- 2 + 3 Mute Swans
- 5 Greylag Geese: 4 left and 1 arrived
- no Canada Geese
- 10 (5♂) + 11 (2 broods) Mallard
- 10 Tufted Ducks
- 0 + 3 (1 brood) Great Crested Grebes
- 2 + 2 (2 broods) Moorhens
- 14 + 2 dependent juvenile Coots
- 22 (4 juveniles) Black-headed Gulls

Definitely a record shot taken as the Hobby shot across at typically high speed. At least I got the camera to this one!
Of interest between the lake and The Flash
- Moorhen(s) heard at the lower pool
- 11 Starlings on lamps: this species is usually absent / scarce around the estate outside the breeding season.

26 Aug 18

Priorslee Lake only

9°C > 10°C: Lowering overcast with rain after 07:30. Calm: light SSE wind later. Very good visibility, decreasing at onset of rain
Sunrise: 06:09 BST

Priorslee Lake: 05:30 – 08:30

(104th visit of the year)

Two new species for my 2018 site year-list
- a Black Tern first noted at c.07:15 and present throughout thereafter. A species normally seen in Spring during spells of E wind and especially during and after thunderstorms. My second autumn record and my first record for two years
- 5 Common Shelduck flew around at c.08:15 but did not land. Another species that normally only drops in on Spring passage. Probably my first autumn record and certainly my largest one-day number
Takes my site total this year to 93 bird species

Other bird notes from today:
- 2 adult Mute Swans dropped in briefly at 06:50. Soon seen off
- the Greylag Geese on the lake were outbound birds that stopped off (not counted in fly-overs)
- one of the Canada Goose parties was outbound at the same time (07:05) as the Greylag Geese were inbound
- the Tufted Duck was seen leaving 06:30
- fewer Coots likely because some were hiding from the rain
- apart from the 3 Feral Pigeons overhead there were at least 45 in a mixed party with Stock Doves and Wood Pigeons put up from stubbles to the NE
- the only House Martins seen today were 5 over the estate that flew away E – I think they were just passing over rather than local birds

Today’s bird totals

Birds noted flying over or flying near the lake:
- 59 Greylag Geese [25 (2 groups) outbound; 34 (1 group) inbound]
- 62 Canada Geese [62 (5 groups) outbound]
- 5 Shelduck
- 1 Grey Heron
- 1 Common Buzzard
- 2 Black-headed Gulls
- 3 Feral Pigeons
- 2 Stock Doves
- 92 Wood Pigeons
- 8 Jackdaws
- 4 Carrion Crows
- 3 Starlings
- 1 Pied Wagtail

Hirundines etc. noted
- 5 House Martins

Warblers noted:
- 10 (2) Chiffchaffs
- 2 Blackcaps

The counts from the lake area
- 4 + 3 (1 brood) Mute Swans
- 11 Greylag Geese
- 2 Canada Geese
- 10 (?♂) + 2 (1 brood) Mallard
- 1 Tufted Duck
- 1 Grey Heron
- 6 + 4 (2 broods) Great Crested Grebes remain
- 7 + 10 (? broods) Moorhens
- 87 (near) adult + 7 dependent juvenile Coots
- 1 Black Tern
- 9 (2 juveniles) Black-headed Gulls

And other notes
Too dull and chilly and, latterly, wet for any insects to be flying
- moths on the lamps
- 2 Agriphila tristella (Common Grass-veneer)
- 1 Centre-barred Sallow
- flies etc. identified
- just a few wasps sp.
- spiders noted
- 1 probable Garden Spider (Arameus diadematus) attacking a wasp sp. on a lamp

The party of five (Common) Shelduck flying over and away. Ageing not really possible here.

Three seen here: from the right what seems to be an adult male with the larger breast band (they lack the swollen bill-base at this time of year); an adult female next; and then a juvenile with just a hint of the breast band. The group was likely a family party of parents and their three offspring. All Shelduck fly, post-breeding, to Heligoland Bight where they all moult their flight-feathers simultaneously.

Several necessarily poor record shots of this morning’s Black Tern. Poor because the light-level was low, the bird was some way away and it is a rather small species. Not much ‘black’ on the head at this time of year. The only confusion species is the very uncommon White-winged Black Tern which would not show such a strong dark shoulder (carpal bar) and has an obviously shorter bill.

In this view we see the breast-side is marked – never is on White-winged Black Tern.

And a flight shot.

Not an identification shot but shows the size comparison with Black-headed Gull. Black Tern about two-thirds the size: it is c.25mm long with a wing-span of c.60mm: a Black-headed Gull is c.38mm long and has a wing-span of c.90mm.

This is a Centre-barred Sallow moth. All sallow moth species are to be found heading in to Autumn. My first here since 2015.
A spider – I think a Garden Spider (Arameus diadematus) – gets its own back on a wasp sp.

Priorslee Lake: 05:20 – 06:50 // 07:40 – 09:35
The Flash: 06:55 – 07:35

9°C > 14°C: Fine and clear with a few patches of cloud to N that mostly melted away again. Once more some puffy clouds after 09:00. Moderate WNW wind. Very good visibility.

Sunrise: 06:07 BST

Priorslee Lake: 05:20 – 06:50 // 07:40 – 09:35

(103rd visit of the year)

Bird notes from today:
- no Canada Geese seen or heard around the lake today
- the 6 Cormorants flew SW at 06:10
- Jackdaw numbers have increased in the last few days: no sign of any roost dispersal, just singles / pairs flying over in rather random directions
- House Martins heard over at 06:05 and 06:10 but not located; 4 flew S at 06:25; 4 flew E at 08:10. Thereafter birds congregated downwind of the dam until there were >20 present (with at least 2 Barn Swallows joining in). Quite how many of these were passing and how many opportunistic local birds is impossible to say

Today’s bird totals

Birds noted flying over or flying near the lake:
- 107 Greylag Geese [53 (6 groups) outbound; 54 (3 groups) inbound]
- 6 Cormorants
- 1 Sparrowhawk
- 8 Black-headed Gulls

And other notes
- butterflies
- 4 Speckled Wood again
- no moths on the lamps or identified elsewhere
- damselflies / dragonflies
- 2 Blue-tailed Damselflies
- hoverflies
- 1 unidentified Eristalis sp. (Drone-fly)
- 1 Syrphus ribesii

- flies etc. identified
- lots of wasps sp. again
- beetles or bugs noted
- a 7 Spot Ladybird (Coccinella 7-punctata)
- no spiders noted
- no different plants noted

The sunrise for what it was worth.

Some warbler photos today – get them before they leave. Here is a Chiffchaff. Note that while the legs are black (like they are supposed to be, even though they are not always!) then the feet are most definitely orange-brown. Very weak supercilium. At this time of year a Willow Warbler would appear much more yellow-toned and with a strong supercilium and dark line through the eye.

Can be quite acrobatic after food.

This is a different individual. I am pretty certain this is a juvenile with rather scruffy plumage and a mixture of brown and grey tones.

Obviously a Blackcap: but is it a female or a juvenile (of either sex)? I am not certain but I would vote for an adult female on the basis of the very dark iris. I would expect a juvenile to have a more orange or brown iris.

A well-striped thorax is a good clue for the hoverfly Helophilus pendulus (The Footballer). In fact there are several hoverflies that show a striped thorax, though none quite so prominently. Here the insect is deep inside a Convolvulus flower.

Inside another Convolvulus flower was this Syrphus ribesii hoverfly.

The 7 Spot Ladybird (Coccinella 7-punctata): 3 spots on each wing (elytron) and one spanning where the elytra join behind the head (at the bottom of the photo).

10°C > 15°C: Fine and clear with a few patched of cloud to N that melted away. Puffy clouds after 09:00. Moderate, even fresh at times, WNW breeze. Very good visibility

Sunrise: 06:06 BST

Priorslee Lake: 05:00 – 06:50 // 07:45 – 09:30

(102nd visit of the year)

Best bird today was the Green Sandpiper that I flushed off the SW area at 06:00. My 91st species of bird here this year; only my 3rd record here in >25 years; and my first here for at least 5 years. Unfortunately because I did my first circuit of the lake ‘the other way around’ this morning I had little opportunity to see this bird before it flushed and apparently left

Bird notes from today:
- a pair(?) of adult Mute Swans visited but was soon sent packing
- different behaviour from the geese this morning. For the past few weeks they have left outbound between 05:45 and 06:00; and returned inbound after 08:00, mostly after 09:00. A few in mixed parties but often in single-species groups. This morning I heard Canada Geese c.05:30 but was not in a position to see them. Almost all the geese outbound at the normal time were Greylags. Then at 06:20 a large mixed group (too large to even guess at separate species totals) flew inbound. I am assuming these had been feeding in the fields overnight – it was a bright moonlight night. A few more Greylags inbound later and the usual mixed party stopping off at the lake
- 2 Tufted Ducks pitched in at 05:40 and left again at 05:55. Two on the water by 08:30 then stayed (same?)
- the juvenile from the ‘second’ pair of Great Crested Grebes was still some way from its parents most of the time: at least it is still here
- the local Common Buzzards went for a fly-about and got as far away as the other side of The Flash, causing consternation amongst the Wood Pigeons and Black-headed Gulls. 2 other birds seen high to the N
- just 4 House Martins seen again: these to the E, downwind of the dam, presumably feeding on insects blown across the water and up over the dam

Today’s bird totals

- 117 Greylag Geese [105 (10 groups) outbound; 12 (1 group) inbound]

A half-decent sunrise.

Flaring briefly as the sun came up.

And allowing an arty shot of a Mallard.

The departing visiting Mute Swans. The lead bird – a cob I think – seems to be missing a few wing feathers. Just moulting I expect.

Flying first-winter Black-headed Gull. Its tail is twisted and we are looking at the neat band on tip of the underside – though the upper side would look much the same.
This different first-winter Black-headed Gull appears to be looking intently at the feather in the water and possibly wondering whether it can be eaten.
The long antennae make this a bumblebee rather than a hoverfly. It is the Common Carder Bumblebee (Bombus pascuorum). I read on the Naturespot website “Carder Bumblebees earn this name from their habit of combing material together (carding) to create a covering for the cells containing the larvae”.

The Flash: 06:55 – 07:40

(84th visit of the year)

Notes from today
- probably even more geese as new arrivals quickly sought shelter inside the island
- quite why so many of the Mallard were clearly adults today when so many had appeared to be juveniles yesterday will probably remain on of life’s mysteries
- the juvenile Great Crested Grebes are more or less independent now. Still to be taught to fly
- the Common Buzzard overhead was one of the birds from the Ricoh copse by the lake on a fly-about, scattering the gulls

Birds noted flying over or near to The Flash
- 1 Sparrowhawk
- 1 Common Buzzard
- 8 Wood Pigeons

Hirundines etc. noted
None

Warblers noted
None

The counts from the water
- 2 + 3 Mute Swans as usual
- 76 Greylag Geese: 37 of these arrived
- 112 Canada Geese
- 27 (16♂) + 11 (2 broods) Mallard (see notes)
- 16 Tufted Ducks
- 2 + 3 (1 brood) Great Crested Grebes
- 2 Moorhens
- 13 + 2 dependent juvenile Coots
- 54 (2 juveniles) Black-headed Gulls only

Of interest between the lake and The Flash
- 1 Common Buzzard over
and
- 1 Flounced Rustic moth (the same as yesterday) on the roof of the tunnel under Priorslee Avenue

Priorslee Lake and The Flash

Priorslee Lake: 05:35 – 06:40 // 07:35 – 09:20
The Flash: 06:45 – 07:30

13°C > 16°C: Started with both low and medium overcast after overnight rain. Mid-level cloud moved away c.06:00 with low cloud beginning to break after 06:30. Hazy sun thereafter. Calm start; light WSW breeze later. Very moderate visibility to start, becoming very good with clearance

Sunrise: 06:03 BST

Priorslee Lake: 05:35 – 06:40 // 07:35 – 09:20

(101st visit of the year)

Bird notes from today:
- the same(?) small group of Greylag and Canada Geese stopped off inbound
- I fear for the juvenile from the ‘second’ pair of Great Crested Grebes. It came off the parent’s back and both adults went away leaving it bobbing about close to Coot territories. I did not see them return. The juvenile was not heard to call / beg for food either
- a Coot seen gathering sticks to add to its nest: too late I would have thought
- 2 Barn Swallows high overhead were flying W. South Africa is the other way guys
- just 4 House Martins seen over the area today
- strangely there were just 2 Magpies on the football field – there are usually 8 – 14 birds here. They were not obviously elsewhere either
- 2 Carrion Crows flew high, and flew past 2 flying high the other way. Did not seem to be connected with the resident pairs at each end of the area
- male Reed Bunting seen this morning: the first I have seen since mid-July

Today’s bird totals

Birds noted flying over or flying near the lake:
- 121 Greylag Geese [98 (7 groups) outbound; 23 (4 groups) inbound]

- 10 Black-headed Gulls
- 3 Lesser Black-backed Gulls
- 3 Herring Gulls again
- 12 Feral Pigeons
- 6 Stock Doves (2 pairs; 2 singles)
- 64 Wood Pigeons
- 3 Jackdaws
- 4 Carrion Crows

Hirundines etc. noted
- 2 Barn Swallows flew W!

- 6 + 9 (6? broods) Moorhens
- 90 (near) adult + 8 dependent juvenile Coots
- 17 Black-headed Gulls

And other notes
- the sheer number of wasps makes picking and eating the Blackberries rather a risky business
insects etc., at least partly identified
- no butterflies
- moths on the lamps
- 4 Agriphila tristella (Common Grass-veneer)
- 1 Agriphila inquinatella (Barred Grass-veneer) again
- no moths identified elsewhere
- damselflies / dragonflies
1 Common Blue Damselfly
2 Blue-tailed Damselflies
- hoverflies
- >1 Episyrphus balteatus (Marmalade hoverfly)
- >5 drone flies (Eristalis sp.): at least 1 an Eristalis pertinax (Tapered Drone-fly)
- 1 Melanostoma scalare (Chequered Hoverfly)
- 1 male Sphaerophoria scripta (Long Hoverfly)
- flies etc. identified
- VERY many wasps sp. again
- many ‘greenbottle’ flies
- no beetles or bugs noted
- no spiders noted
- no different plants noted

There must have been some heavy rain and / or strong winds last night: these reeds are looking rather flattened. Just as well the Reed Warblers have finished nesting.

The lonely waif of a Great Crested Grebe juvenile with a Coot looking on. The parents were some distance away and not showing any real interest.

How does it do that – land on top of a yacht mast? Wood Pigeons must be more agile than they look.

An upgrade: my best-ever photo of Agriphila tristella (Common Grass-veneer) showing the pale yellow longitudinal (at rest) stripe to good effect.

Several drone flies around today. This, at least, is an Eristalis pertinax (Tapered Drone-fly). Not only does the body look tapered but we see the diagnostic yellow tarsi that Eristalis tenax (the Common Drone-fly) lacks.

An intriguing hoverfly with a very obvious yellow scutellum.

The same specimen perched at a different angle. It is a male Sphaerophoria scripta (Long Hoverfly). Males are easy to identify because it is the only species of hoverfly where the body is longer than the wings. Females have shorter bodies and are difficult to separate from other Sphaerophoria species.

I keep hoping to find a supposedly common Emerald Damselfly – not common around here for some reason. This is ‘just’ a female Blue-tailed Damselfly – females do not show a ‘blue tail’.

The Flash: 06:45 – 07:30

(83rd visit of the year)

A very quiet morning with low counts of most things. No obvious reason

Other notes from today
- no Canada Geese at all!
- almost all the Mallard were by the edge of the water today allowing critical examination. From that I concluded that no fewer than 27 of the birds were immatures of this year from at least 6 broods. The most recent brood of 5 was present and correct
- juvenile Moorhen again seen trying to fly up, jumping and flapping from same spot. Full marks for persistence
- one bird of the Coot pair with the two still small and dependent juveniles had taken them across the water: meanwhile the other bird was adding more sticks to the nest!

Birds noted flying over or near to The Flash
- 18 Feral Pigeons (2 groups, 1 single)
- 7 Wood Pigeons

Hirundines etc. noted
None

Warblers noted
- 1 Chiffchaff

The counts from the water
- 2 + 3 Mute Swans
- 9 Greylag Goose: 7 flew off
- no Canada Geese
- 9 (3♂) + 27 (6 broods) Mallard (see notes)
- 9 Tufted Ducks only
- 2 + 3 (1 brood) Great Crested Grebes again
- 1 + 2 (2 broods) Moorhens
- 11 + 2 dependent juvenile Coots
- 7 (no juveniles) Black-headed Gulls only

Of interest between the lake and The Flash
- 1 adult Moorhen seen at the upper pool
- 2 House Martins over
- 1 Blackcap calling above the upper pool
and
- 1 Flounced Rustic moth on the roof of the tunnel under Priorslee Avenue.

On the roof of the Priorslee Avenue tunnel was this Flounced Rustic moth. The characteristic (if somewhat variable in strength) marks in the middle of the wings where they touch are diagnostic of this species. My first in the area for three years even though it is a very common species.
