Priorslee Lake, Woodhouse Lane, The Flash, Trench Lock Pool and Trench Middle Pool.

11.0°C > 15.0°C: After what was probably the most colourful sunrise of the year it was yet again cloudy at medium level, even with spots of rain c.09:00. An almost calm start with moderate SW breeze developing. Mainly very good visibility with a few localised distant mist patches.

Sunrise: 06:31 BST

* = a photo today.

A change of plan for today. Now the schools have returned it is difficult to get around the lake and then up and back to The Flash without getting caught in the school run chaos. So I stayed at the lake until afterwards, diverting to Woodhouse Lane to see whether there was any visible migration. There wasn't!

Priorslee Lake: 05:02 – 07:10 // 08:10 – 09:13

(185th visit of the year)

Bird notes:

- With flat calm water early all the juvenile Great Crested Grebes were easily located, now scattered all around the water. Some, often submarine, adults may have been missed.

- 30 Lesser Black-backed Gulls flew SE between 06:05 and 06:30. All subsequent sightings were birds flying N / NW with at least 13 stopping off at the lake to drink and squabble.

- One of the Blackcaps was sub-singing quietly. I cannot recall previously hearing song after the end of the breeding season.

Birds noted flying over / near here:

- >223 Greylag Geese (143 outbound in four groups; >80 inbound in single large group with Canada Geese)
- >166 Canada Geese (66 outbound in three groups; >100 inbound in single large group with Greylag Geese)
- there were likely some Greylag x Canada Geese in the inbound group
- 67 Lesser Black-backed Gulls
- 2 Stock Doves (singles)
- 62 Wood Pigeons
- 9 Jackdaws
- 1 Rook again
- 2 Pied Wagtails

Hirundines etc. logged:

Count of warblers logged (singing birds in brackets):

- 8 (2) Chiffchaffs again
- 3 (1) Blackcaps

Counts from the lake area:

- 2 + 5 Mute Swans
- 1 Canada Goose: stopped off on return
- 12 (7♂) Mallard
- 3 Cormorants: all arrived; one departed
- 1 Grey Heron
- 16 + 7 (5 broods) Great Crested Grebes

Moths:

None

Mammals

- 4 Pipistrelle-type bats
- 1 Grey Squirrel

New flowering plant species recorded:

None

Make a note – the moon was visible two mornings in a row. Not for long today.

Much cloud around, increasing all the while. An excellent sunrise as this sequence shows. Well before dawn with the sky beginning to colour.

That is better.

Even better as colour spreads across the sky.

Zoomed in a bit to get the full effect of the colour.

And from a different angle.

Woodhouse Lane area: 07:10 – 08:10

(13th visit)

Bird notes:

- Apart from a few Yellowhammers all the breeding birds seem to have moved away. Yellowhammers are very late breeders, timed to utilise the spilt corn in stubbles after the harvest. I saw four birds together, likely a family party

- Otherwise the only notable sighting was 14 Meadow Pipits that flushed from stubbles as I walked along the lane past them.

Count of warblers logged (singing birds in brackets):

- 5 (2) Chiffchaffs

(Ed Wilson)

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

The Flash: 09:15 – 10:02

(170th visit of the year)

Bird notes:

- Two of the Mute Swan cygnets were with the pen. Three others were loosely with the cob and his current favourite, his 2018 daughter. The other cygnets were likely inside the island with geese.

- I assume most of the geese were trying to sink the island by resting up after their early morning exercise and feed.

- Perhaps many of the Mallard were also there?

- Another high count of Coots. All forced off the island by the geese?

- A Grey Wagtail on the roof of one of the estate buildings to the E. Somewhat to my surprise this is my first record of this species here in 2020 and becomes bird species #72.

Birds noted flying over / near The Flash:

- 2 Herring Gulls: immatures
- 1 Wood Pigeon

Hirundines etc. logged:

- 1 House Martin only

Count of warblers logged (singing birds in brackets):

- 5 (3) Chiffchaffs

Counts from the water:

- 3 + 5 (1 brood) Mute Swans (see notes)
- 6 Greylag Geese only
- 1 Greylag x Canada Goose
- 35 Canada Geese
- 20 (11♂) Mallard only
- 32 (9?♂) Tufted Duck
- 3 Great Crested Grebes still
- 7 adult and juvenile Moorhens
- 81 adult and juvenile Coots
- 6 Black-headed Gulls

On a single lamp pole:

- 1 Common Wasps (Paravespula vulgaris)

Also notable

- The wall of Ivy near the Priorslee Academy will soon start flowering and become a magnet for bees, wasps and hoverflies. Another week?

- *A large number of fungus apparently growing on roots of a tree at the top end. The tree looks healthy-enough but I am not an expert/

I did some 'gardening' to move some of the twigs and leaves. Not much I could do about the soil without damaging the fungus bodies. They were all around the base of a healthy-looking tree.

Another cluster. I was not able to view any stems – in fact they seemed to be almost stem-less. Thus I could not see how any gills were arranged. As usual none of the copious photos of fungus on the web seems to match these specimens.

Trench Lock Pool: 10:12 – 10:40 // 11:15 – 11:22

(25th visit of the year)

Bird notes:

- All four of the juvenile Great Crested Grebes with one of the adults. Could the other adult be sitting for a second brood?

- A Grey Wagtail.

Birds noted flying over / near here:

None

The local Wood Pigeons and Jackdaws not included

Hirundines etc. logged:

- 4 Swifts
- 2 Sand Martins
- 3 Barn Swallows
- 8 House Martins
This location seems to attract hirundines during passage times (there are local breeding Swifts and House Martins). Perhaps because it is very open to the N and E and therefore easy to see by migrating birds..

Count of warblers logged (singing birds in brackets):

- 2 (1) Chiffchaffs

Counts from the water:

- *2 + 6 (1 brood) Mute Swans
- yet again no Mallard...
- or Tufted Duck
- *1 + 4 (1 brood) Great Crested Grebes
- 5 adult and juvenile Moorhens
- 18 adult and juvenile Coots
- 14 Black-headed Gulls
- *4 Lesser Black-backed Gulls
- *1 probable immature Yellow-legged Gull

Well now: what is going on here? These three guys are doing the annual ringing of the Mute Swans and their cygnets. They told me they were having a frustrating morning. They had started at Newport Canal on the 'easy pair and their cygnets' only to find them disinterested in their proffered bread. Moving on to here they found the pen – this is she – in some distress with fishing hooks wrapped around one leg. Here they are being watched by her mate and some of the cygnets as they unwind the hooks and then add a BTO metal ring and a smart blue Darvic ring. They later managed to ring the cob as well – neither of this pair had been ringed previously. The cygnets all evaded capture. They will try again in a few days. I will report the Darvic numbers in due course.

A motley collection of immature large gulls. The bird at the back left caught my eye because of its pale head. The closest bird seems to be a juvenile Lesser Black-backed Gull about to moult in to first winter plumage (hatched this year). On the back right a first summer Lesser Black-backed Gull about to moult in to second winter (born 2019). The interesting bird? Well...

Note the large black bill. This rules out Caspian Gull – one of the pale-headed options. My vote is for a juvenile Yellow-legged Gull starting its moult in to first winter plumage.

Gazing at its own reflection? An immature Great Crested Grebe still with remnant face stripes but beginning to acquire head plumes.

Trench Middle Pool: 10:45 – 11:10

(25th visit of the year)

Bird notes:

- So where are all the geese? And Mallard come to that. Could some have been inside the island? There seems to be few, if any, people 'feeding the ducks' at the moment. Perhaps they have gone elsewhere.

- The two juveniles from the first brood of Great Crested Grebes not seen.

- Notable increase in Coot numbers.

- Grey Wagtail here as well as at Trench Lock. Could be the same bird.

Birds noted flying over / near here:

None

Hirundines etc. logged:

None

Count of warblers logged (singing birds in brackets):

- 1 (0) Chiffchaff

Counts from the water:

- 2 Mute Swans
- no Greylag Geese
- 2 Canada Geese only
- 1 all-white feral goose
- 7 (2♂) Mallard only
- 15 (2?♂) Tufted Duck
- 1 Grey Heron again
- 2 + 2 (1 brood) Great Crested Grebes
- 8 adult and juvenile Moorhen
- 45 adult and juvenile Coots
- 8 Black-headed Gulls

Otherwise, notable

- *both white and pink cyclamen. The pink ones could be genuine wild Sowbread (Cyclamen hederifolium). Seems a strange place to find garden escapes.

A cluster of what are probably Sowbread (Cyclamen hederifolium), more commonly known as Cyclamen. There are a number of cultivars but this pink form with the magenta at the base of each petal seems to be a genuine wild flower.

However this white cluster alongside would be unusual in the wild so perhaps neither is.
