Occurred on May 10, 2018 / Yellowstone National Park, Wyoming, USA
Info from Licensor: "In Lamar Valley at Yellowstone Park in May, 2018, I witnessed these three eagles hunting a duck in Soda Butte Creek. I was able to take video and still photos for 10 or 15 minutes. I was unable to stay any longer, so I don't know how this ended for the duck. This took place about 600 yards from my location. This was taken with a Nikon p900 camera, hand held."
