Sparrowhawk.

I placed a perch near my bird feeders a couple of years ago knowing that the local Sparrowhawks were regular visitors, thinking it would be perfect for them to land on. In all the times I've sat in my hideout (shed)I'd not had one land there, untill the other day when this immaculate male bird suddenly appeared in front of me, staying and eying up the small birds for about five minutes. It did'nt catch any so not had to have the mixed emotions of predator and prey.
