I was astounded when I saw stats on how many birds get killed by cars every year (I think it was posted here a while back). Its like an ongoing bird genocide. No wonder birds shit all over parked cars. We can’t even fault them for this, but it would also be illegal for us to join in. :D
I’d love to know the difference in average bird fatalities for a busy 4 lane highway vs a double-tracked rail line with overhead catenary.
