Over Pencarreg lake yesterday afternoon were more than 50 hirundines. Approx 30+ swallows & 20+ sand martins. Try as I might I could see no house-martins. The overall number seemed to be increasing as we watched!
Going back shortly before sunset & 1 swallow was all that was left.
Also 8 tufted duck, and amongst the Canada geese was what looked like a bar-headed goose (escapee).
Moorhen, mallard, cormorant, Heard but not seen, little grebe.
Later on, after dark, a tawny owl heard.
