These miners are using guns, drones, and fireworks to keep birds from landing on a toxic lake

  • A former copper mine in Montana has been flooding with toxic groundwater since the 1980s.
  • The water is so toxic that any birds that land on the lake get cooked from the inside out.
  • Now, a group of specialists use guns, fireworks, and high-tech tools to shoo birds off the surface and save their lives.

If migrating birds land on Montana’s Berkeley Pit for just a few hours, they die. Now, miners use a rifle, drones, and lasers to scare them away.
