However, a study published today in the journal Science provides evidence that ravens may be remembering hunting hotspots and scavenging for food, rather than chasing wolves. Researchers outfitted the ravens with small GPS backpacks over their wings, and the wolves wore collars equipped with tracking devices. Ravens and wolves in YellowstoneOver time, the scientists observed ravens routinely appearing at kill sites, concentrated in northern Yellowstone where wolf kills are clustered. In future research, the researchers hope to further understand more about when and how ravens learn about the regional concentration of wolf kills. They’re curious if young ravens can uncover these patterns early in life, or if developing the skill takes years of experience.
