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.<\/p>\n
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.<\/p>\n
Ravens weren’t just following wolves \u2013 they were clocking kill patterns, creating mental maps to support future food quests.<\/p>\n
The international research team attached tiny GPS trackers to 69 ravens \u2013 an impressive number considering the painstaking work in trapping the particularly observant birds.<\/p>\n
“Even small changes in their environment can make them suspicious,” said<\/a> Loretto, who is at the University of Veterinary Medicine in Vienna, and began the research at the Max Planck Institute of Animal Behavior.<\/p>\n 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.<\/p>\n The park was uniquely suited to the study.<\/p>\n “This work would not have been possible anywhere other than Yellowstone,” said<\/a> co-author and wildlife scientist John Marzluff of the University of Washington.<\/p>\n 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.<\/p>\n 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 \u2013 even as the birds were still able to quickly arrive at a kill.<\/p>\n Deeper analysis showed ravens were in fact revisiting spots where wolves commonly took down prey \u2013 animals like deer, elk, or bison \u2013 suggesting the birds were creating and memorizing a “resource landscape.”<\/p>\n Some birds would fly nearly 100 miles (up to 155 kilometers) in a single day, seeking out places they seemed to expect might feature wolf kills.<\/p>\n It was “a much larger area than I ever imagined,” said Marzluff.<\/p>\n Short-range cues still matter: ravens might be following signals like wolf howls to find fresh kills at shorter distances.<\/p>\n But broadly speaking, the researchers said ravens were counting on their memory to lead the search.<\/p>\n Wolf kills aren’t distributed at random, Loretto said, occurring more often on flatter terrain or in open valleys where chases are more likely.<\/p>\n Ravens might remember past feeds or notice indirect signs like bones as they establish their mental maps.<\/p>\n “Animal cognition in the wild may sometimes be more sophisticated than we tend to assume,” Loretto said.<\/p>\n Raw deal<\/p>\n The wolf-raven relationship is sometimes described in popular culture as harmonious, but Marzluff said it’s ultimately pretty lopsided.<\/p>\n Wolves have been observed swatting the birds away, even appearing to designate a pack member to stand guard.<\/p>\n The birds noisily fight over their stolen feast, a potential tip-off to other scavengers.<\/p>\n And a single raven can carry off half a pound (220 grams) of meat. When the birds arrive in the dozens, that can make even a downed bison disappear quickly, Marzluff said.<\/p>\n “Ravens get a lot more out of this deal than wolves do,” he added.<\/p>\n The scientist said he hopes future research could focus on how young birds develop their knowledge.<\/p>\n![\"A](\"https:\/\/www.newsbeep.com\/nz\/wp-content\/uploads\/2026\/03\/Raven-with-GPS-Backpack-642x361.jpg\")
