Scientists thought ravens followed wolves for food. A 2.5-year GPS study told a different story.

In Yellowstone National Park, ravens have demonstrated remarkable intelligence by devising a unique method for locating food. Instead of merely tailing wolves, these clever birds create mental maps of successful hunting zones. This memory-based strategy enables them to navigate across significant distances and head straight for areas likely to have wolf kills, overturning prior beliefs about their feeding habits.
