Why they were even hunted to extinction is a bit beyond me since according to this, the damn thing’s didn’t even make good eating:
Well, just think, you big city dwellers, that one day you might not have to worry about pigeons crapping all over your cars and statues. They might just return down an evolutionary path taken by themselves once before and become large, flightless hunks of unappealing meat products you can runover with your car!
I thought it was the Brits that killed them off. Maybe the Dutch of the time felt the same way the Brits did about hunting, i.e. killing an animal that just sits there and looks at you was jolly good sport.
