I'm no Stephen Debus, but the bird's GISS looks good for Brown Goshawk to me.
I agree with what Greg has mentioned about the wing and that is what is
bothering me, I would have expected BrGos would have more length vs width in
the wing profile in soaring mode (may not be fully stretched though). Tail
could be a little short as well? There is a bit of a bulge in the back of the
secondaries that is Sparrowhawk-esque as well.
As Nikolas pointed out it was the bulky body that pulled me toward BG as well.
Am I picking up immature plumage though? Dappled breast perhaps?. Might be the
reasons for wing and tail shortcomings and the hooded look referred to by
Harry??
