It's amazing how loud the noise is, isn't it?
It doesn't surprise me that the bird made a fist sized dent in the surface, since I've seen the aftermath of a Thrush meeting the l/e of a PA28 wing and that was also fist sized and quite deep.
I did accept the rental aircraft for a flight, since the incident was logged in the tech log and an engineer had inspected it and signed it off (bird type was named too), but I was surprised by the severity of the damage caused by a bird that literally weights a few ounces.
