Just ten miles from downtown Boise, scientists are studying golden eagle migration in southwest Idaho. And they’re using roadkill to do it.
Scientists from the U.S. Geological Survey, Boise State University and Idaho Fish and Game created a series of motion-sensitive camera traps. They drag a 250-pound road-killed elk through the snow to the trap and leave. The cameras do the work, snapping pictures of whatever scavenger comes by for a snack.
