Just the title — Transplanting Beavers by Airplane and Parachute [PDF] — of this 1950 report in the Journal of Wildlife Management raises questions. Like, for goodness sake, why? And how? Did they specially make tiny beaver-sized parachutes and goggles, and push them out of the cargo hold, one by one, like a tiny dam-making army? Once on the ground, did the beavers suffer post-traumatic stress from the sudden drop? Or did they spend the rest of their days mourning in rivers, longing for another taste of the sky?
