Ravens find wolf kills using memory, not tracking, in Yellowstone.
A 2.5-year GPS study in Yellowstone reveals ravens locate wolf kills using advanced spatial memory, not by following wolves, with only one recorded instance of long-distance tracking.
Ravens repeatedly visit high-kill areas, relying on learned knowledge of terrain and wolf behavior to efficiently access food.
In return, wolves may benefit from ravens’ ability to spot carcasses, especially in snowy landscapes.
The partnership highlights mutual intelligence, strategic planning, and ecological cooperation between two highly cognitively advanced species.
