I saw a kangaroo die last week. Driving to work along my usual rural stretch of road, a kangaroo was lying in the middle of my side of the road. It was clearly alive, head and upper torso upright. Not a youngling, not an adult, maybe an older adolescent. Cars going the other way slowed down to rubberneck/drive carefully. I don't know much about kangaroos, but I do know that they don't stay near traffic for the fun of it.
