The bird carcass was stuck in the rear plate of the spinner on arrival at BHX. The bird appears to have been a yellow legged hawk-perhaps a twitcher could identify it.
I am a birdwatcher, anyone got a photo? Many birds of prey have yellow legs I would imagine it was a Common Buzzard which is reasonably big. Failing that it could be a Kestrel (bit small) or female Sparrowhawk (can be biggish) or something more exotic. As it is related to m x v squared I guess speed is more important than mass of the bird, although I would think a large Buzzard at least twice the mass of a Kestrel.
From my PPL memory Southampton is 1723m (02/20) and there is maintenance (executive stuff) but not sure FlyBe use it
