I'm in Tywyn, just 4 miles North of Aberdovey, which is just down the Dyfi from the observation site. I saw them at the furthest point of my run, couple of miles into the hills. Did your Mrs manage to get a glimpse of the pair? An odd bird is also glimpsed hawking the Dysynni just a mile from me but despite walking along there many times I've never been fortunate enough to get a glimpse, perhaps this year if I'm lucky.
