Priorslee Lake [with Woodhouse Lane] and The Flash

Priorslee Lake:  04:50 – 06:00 // 06:45 – 09:15
[Woodhouse Lane:  08:00 – 08:40]
The Flash:  06:05 – 06:40

6.0°C > 8.0°C:  Low overcast started to lift and break somewhat after 08:15. Light E wind. Moderate visibility

Sunrise: 05:21 BST

Main feature today was an unprecedented arrival of Sedge Warblers. At least eight were singing around the lake and another (my second this year) at The Flash. The noise of these birds tended to drown out the singing Reed Warblers and these may be under-recorded

There were also probably two different Lesser Whitethroats moving through the lake area

Priorslee Lake:  04:50 – 06:00 // 06:45 – 09:15

(123rd visit of the year)

Other bird notes from today
- a pair of Mallard seen on the water was likely the pair seen later on the football field (actually it is no longer used for football and only has an artificial cricket strip)
- as on several other days recently a pair of Tufted Duck ‘appeared’ after 08:00. Are they lurking in the reeds or are they flying in?
- very briefly before dawn all four Great Crested Grebes put in an appearance with the long-absent second bird from the N side holding its back feathers arched as if it might be carrying juveniles. Just two birds seen later and no sign of juveniles
- no juvenile Coots noted: likely being still being brooded by the adult on the chilly morning
- for the first time I can remember no Wood Pigeons were noted flying over
- a tight group of 80 Jackdaws passing over at 05:10 was unexpected: groups do not usually reform until much later after the breeding season
- the first Lesser Whitethroat was rattling away in the vegetation by the Wesley Brook footbridge at 05:30. Nothing heard later until at 08:45 a bird was rattling away in the SE bushes, before moving quickly W along the S side and then again no longer heard. Assumed to be different birds passing through

Nothing on the lamp poles pre-dawn

Later
- 1 Common Roller (Ancylis badiana) moth
- 1 Tawny Mining Bee (Andrena fulva)
- 1 wasp sp.
- several snails, including a Brown-lipped Snail (Cepaea nemoralis); a probable White-lipped Snail (Cepaea hortensis) and a possible Glossy Glass Snail (Oxychilus navarricus)

Oh no! Not more Sand Martins. Well just one to make two points. I noted two days ago that I had previously not been conscious of the ‘zip’ on the chest of this species. Here we see it is a very variable feature with one well-marked bird; one with a smudge only; and the other unmarked. Note also how deep the ‘V’ fork in the tail can look as the fourth bird comes in to land.

Rather gloomy when I took this so not quite sharp – a Common Roller (Ancylis badiana) moth. My 14th species of moth at the lake this year. I record this species most years.

A rather splendid-looking bee (not a hoverfly as it has long antenna). A Tawny Mining Bee (Andrena fulva). I have not previously recorded this species here but it is a common-enough bee.

With all the wet weather the snails were out in force. I am reasonably sure this is a species of glass snail. It might be Glossy Glass Snail (Oxychilus navarricus). It requires more experience than I have to separate these species.

When I saw this I assumed it would be a White-lipped Snail. However the photo shows the white is not the lip at all and the lip is brown. It is one of the very variable Brown-lipped Snails (Cepaea nemoralis).

This is (I think) a White-lipped Snail (Cepaea hortensis).

And now for something completely different. Had be scratching my head awhile and then I realised it was a very wet Poplar catkin that had fallen off in the rain and was not some bizarre insect.

The Flash:  06:05 – 06:40

(116th visit of the year)

Species added to my 2019 bird log from here
71      Rook
For some reason Rooks are rather unusual here – certainly at the time I am normally present. Last year my first record was again not until May – 26th May 2018

Other notes from here:
- only one brood of five Mallard ducklings located
- possibly more duck Tufted Ducks. All the birds were milling about the edge of the island and the ducks hard to see in the very dull light
- a Coot was still brooding the young so no count possible
- the Sedge Warbler as highlighted. This was in a different location to the bird seen on Wednesday (and not heard yesterday)

Birds noted flying over / near The Flash
- 1 Stock Dove
- 2 Rooks

Hirundines noted
None

Warblers noted (singing birds)
