Plan to wipe out plague of rarest ferret by shooting peanut butter from sky

A fleet of drones could soon send M&M-sized peanut butter-flavoured treats raining down on the Montana grasslands, in efforts to save North America's endangered black-footed ferrets. The plan offers an unusual ray of hope for these rare predators, administering baited plague vaccines across a 1,200 acre habitat to preserve their main food source – prairie dogs. Outbreaks of sylvatic plague have wiped out prairie dogs by the masses, reducing their numbers by more than 95 percent, and thus killing off the ferrets who depend on them for survival.
