Best today was a fly-over Yellow Wagtail: my first here though they likely bred in the fields alongside Woodhouse Lane. As far as I can recall this is my first post-breeding record here – usually Spring migrants enter my log book. Bird species #97 here in 2020 for me.

Other bird notes:
- A group of 16 Cormorants approached from, unusually, the SW and circled over with several looking as if they might peel off and annoy the fishermen. Despite the presence of two individuals already here they eventually decided to move on.

The Flash: 06:35 – 07:30

(145th visit of the year)

Best bird today was a Little Grebe amongst a gaggle of Tufted Ducks in the middle of the water. It seemed to be spooked by me and took, flying unusually high (for a Little Grebe) at over six feet. I did not relocate it and it may have flown off. Only my third record in the last six years, the others also being mid-Summer dates of 15th July 2018 and 19th July 2019. Many years ago this was a relatively common winter visitor lurking around the edges of the island. Bird species #70 here in 2020 for me.

Other bird notes:
- The pen Mute Swan was looking after all seven cygnets. Another swan was seen inside the island though I could not determine whether it was the cob or the 2018 immature – my money would be on the latter.
- Was so dark this morning that seeing along the edge of and inside the island to see Mallard and Coots at rest, made doubly so my a party of 11 duck Tufted Duck milling about.
- The same Racing Pigeon was present when I arrived but gone(?) later.

Birds noted flying over / near The Flash:
- 3 Feral Pigeons

Hirundines etc. logged:
- 3 House Martins

Count of warblers logged (singing birds in brackets):
