Priorslee Lake: 05:15 – 05:35 // 06:40 – 09:25
(150th visit of the year)
Highlight today was an adult Common Gull that flew NE at 07:55. An unusual date to see this species inland though these days any sighting here is unusual.
Other bird notes:
- Not sure what has caused the bumper number of Coots to appear. There were two new broods of juveniles though that does not explain the significant increase in the number of adults counted.
- A juvenile Common Buzzard was heard begging from the Ricoh copse.
- There were new, presumed second brood, Great Tits noted.
- Despite checking several tit parties over the last few days I have neither heard nor seen anything of the Marsh Tit noted on the 16th.
- Just one Sedge Warbler still doing its dancing display flight along the South side.
- The long-term singing Garden Warbler that seemed to have desisted a few days ago was singing very briefly and intermittently first thing only. The other bird is singing away.

The PlantNet app. gave me a choice of several melilot species for this flower, also growing on the dam.
I thought the leaves might help. The app. gave me the same choice of species but ranked in a different order! Back to the Flora to resolve. The denseness of the flowers in the racemes and the sharply toothed leaves point to this being Tall Melilot (Melilotus altissima).

The Flash: 05:40 – 06:35
(146th visit of the year)
It has reported that a family group of perhaps six Pied Wagtails has been visiting a garden in the area (exact location unspecified). I have not seen any in and around The Flash for some weeks though I have recently seen juveniles both with and, later, without parents on the boating platforms and the dam-face at the balancing lake.
Bird notes:
- A return to expected numbers of Canada Geese. The erstwhile goslings can now only be separated by their slightly smaller size having now acquired adult-type plumage.
- There seemed to be four full-grown young Mallard together. I used their bill pattern to determine their sex and these are now included in the adult figures. No obvious ducklings seen.
- The most recent brood of Coots not included today as an unknown were being sheltered by a parent.
- I did wonder about a fourth Great Crested Grebe today. I had seen one at the top end. Later there were three together near the island (including the bird sitting on the nest). I could not relocate any at the top end but there were so many geese in the way I do not think I have a definitive answer
Birds noted flying over here:
- 1 Sparrowhawk
- 3 Jackdaws
- 3 Starlings: together

Nothing noted
Here are what I reckon are a group of four fully-grown ducklings raised here. Looking at the bill colour then the two on the right are drakes and the two on the left are ducks, these showing orange / brown along the edges of the mandibles. It always gives me pleasure to wind people up by noting that it is only the duck Mallards that 'quack-quack-quack-quack'. As evidenced by the bird on the left.

Between the lake and The Flash:
- Five juvenile Moorhens at the lower pool: another briefly seen scampering off the grass looked to be an older brood immature.
- A singing Blackcap preceding me alongside both pools.

In the Priorslee Avenue tunnel:
- the usual few midges of various sizes.
