The Corse even more extensively flooded, unsurprisingly. I began below Castlemartin Church, and had time to see the wing-tagged marsh harrier downstream before retreating in the face of a heavy shower. I re-parked at Gupton and walked down to the hide, where I watched the untagged (1CY ♀) marsh harrier quartering the reedbed for nearly an hour while I sat out a couple of heavy showers. At one point she flushed a female merlin out of some blackthorn - the merlin flew a short distance and perched on top of a bush, swaying in the wind, enabling me to get superb view through my new 20-60x zoom eyepiece on my old Kowa (I'd left the camera in the car, but she would have been too far away). Wing-tags appeared eventually. Two buzzards and a kestrel rounded things off.
The harriers kept mallard, teal and snipe on the move, ducks landed on the open water by the hide, parties of lapwing and golden plover passed overhead. A terrific morning.
