Topend, I didn't say it couldn't happen and even over here we see birds other than pheasants as road kill. You don't say what type of ac had the tail rotor birdstrike, but I'd like to know if it had a fenestron or shrouded system.
I once had a birdstrike in the early hours pulling out if Palace Bks in a Gazelle many a moon ago. After turning back, on having a look a seagull had impaled itself on the pitot tube. What are the chances of that messy mess?
As I said earlier, 'When you have eliminated the impossible, whatever remains, however improbable, must be the truth.'
