Scientists are using drone technology to track declining Steller sea lion populations in Alaska.
Every summer researchers from the National Oceanic and Atmospheric Administration (NOAA) Marine Fisheries Science Center study the animals along the Aleutian Island chain.
They use a variety of methods to count the sea lions including stationary game cameras and manned aircraft that fly over a region where scientists can take pictures.
Since 2014, they’ve been using a hexacopter, or drone, to survey areas as well.
