20 years ago, I hit a buzzard. It was down trying to get the last bite of roadkill, when I hit it with a Mazda pickup. It took out the windshield and was in the cab with me, very dead. I was covered in little cuts from the not so safe glass. Through out the carcass and headed home on back roads at a slow pace with the two foot hole where my windshield had been. After a thorough clean and new windshield, I was still finding feathers a month later.
My second bird kill was a flock of canadian geese that had gotten too used to city life. I was headed home after the midnight shift, driving too fast in my firebird. A flock of geese were crossing from a pond in a park to a companies manicured lawn to feed. I didn't slow down, birds fly right? I hit that flock dead center. I think all told I squished 7 geese. Had to have the firebird put on a lift to clean the underneath of feathers and blood. Yuch!
