Priorslee Lake, The Flash and Trench Lock Pool

7.5°C > 8.5°C: Strip of clear to the E soon filled in; then cloudy with some drizzle at time; clearing somewhat after 09:00. Calm start with moderate NNW breeze springing up. Very good visibility except in drizzle.

Sunrise: 06:38 BST

Priorslee Lake: 05:41 – 07:00 // 07:50 – 09:17

(48th visit of the year)

A Lapwing was heard displaying, apparently over the old Celestica site to the N. I was not in a position to see the bird but nevertheless it becomes my 83rd confirmed species logged from the lake area this year

Other notes from today:
- the two Grey Herons were keeping very much together and one bird was seen in the trees along the N side – prospecting a nest site?
- very strange Jackdaw passage this morning with many just in pairs along multiple flight lines and at many different heights. First 2 birds at 05:56 with 22 logged ahead of the main numbers which started passing at 06:10 and had gone by 06:20. The largest group of 16 was unusually after this time and at 06:32
- as expected good numbers of Sand Martins arrived with the dull and drizzly weather. Single Barn Swallow seen on several occasions – same bird?
- all warbler song was rather intermittent this morning with some birds, Blackcaps especially, perhaps moving about and therefore over-recorded
and
- no moths on the lamps and with the dull breezy weather no insects seen
- seems I was premature to dismiss the likelihood of seeing Cowslips (Primula veris): a few flowers emerging today in a very sheltered spot
- several fruiting bodies of a fungus – perhaps Psathyrella gracilis; perhaps not
