Pretty confident of just having seen a Goshawk over Penarth Head area just a moment ago. Gulls crying usually an indication of something unsettling them. Yesterday c100 linnets in farmer’s field on Fort Road Lavernock and c50 Goldfinch nearer the point. Quite a few grey wagtails over as already mentioned.

Ian – I saw it too. I was birding along the Ely in Grangemoor Park and saw the commotion at a distance over by Penarth Marina. The bird moved directly along the river corridor upstream, almost overhead, before going into a stoop somewhere over the old gasworks by Ikea.
That’s good to know Martin. I saw a couple of sparrow hawks (male and female) over just a couple of days ago but this was much larger. Peregrines and Ravens squabbling most days too.
