Having hit a Pheasant, at 56MPH (Me, not it) with my truck*, and seeing the mess it made of the windscreen, I'd not want to hit one whilst in an aircraft, at xx? feet.
*Southbound A1 near the East of England Showground, at Peterborough. It crossed my path and then did a 180 degree turn, to avoid a northbound H.G.V. Second time of crossing in front of me, it wasn't as lucky as the first time!
