Ravens Don't Just Follow Wolves - They Memorize Kill Sites Across Vast Distances Amazing. And humans need a GPS 🤣 The partnership between ravens and wolves goes back to Norse mythology – Odin's birds scouted ahead and led prey to the god's canines, a relationship that provided food for all. The myth has some roots in reality: when wolves have a successful hunt, ravens are often observed first on the scene, and new research put the legend to the test The study's findings suggest the birds are doing more than just tracking the hunters: they're using navigation and spatial memory techniques to scavenge with sophistication. While "ravens are already well-known for their intelligence," lead author Matthias-Claudio Loretto told AFP, seeing these cognitive abilities "play out at a much larger scale in the wild" produced startling results. Ravens weren't just following wolves, they were clocking kill patterns, creating mental maps to support future food quests. The international research team attached tiny GPS trackers to 69 ravens, an impressive number considering the painstaking work in trapping the particularly observant birds. "Even small changes in their environment can make them suspicious," said Loretto, who is at the University of Veterinary Medicine in Vienna, and began the research at the Max Planck Institute of Animal Behavior. The team had movement data from 20 collared wolves in the famed Yellowstone National Park, a vast protected area in the western United States where wolves were reintroduced in the mid-1990s after 70 years of absence. The park was uniquely suited to the study. "This work would not have been possible anywhere other than Yellowstone," said co-author and wildlife scientist John Marzluff of the University of Washington. Because the environment is open rather than densely wooded, both the birds and wolves are relatively easy to observe at long distances, he told AFP. 'Sophisticated' animal cognition Over two-and-a-half years of monitoring, researchers were puzzled to find just one instance of a raven following a wolf for more than an hour, even as the birds were still able to quickly arrive at a kill.
