Scientists have uncovered a surprising twist in the age‑old rivalry between African lions and spotted hyenas. By fitting GPS collars on 17 lions and 14 hyenas across Namibia’s Etosha National Park and Botswana’s Chobe National Park and Linyanti Conservancy, researchers tracked thousands of real‑time interactions over a four‑year period.
Key findings
The data reveal a clear pattern: male lions tend to move toward hyenas, while hyenas consistently retreat. Lead author Nancy Barker of the University of KwaZulu‑Natal explained, “Our GPS collar data shows that African lions and spotted hyenas leave a measurable signature in the way they move around one another. Spotted hyenas consistently move away from lions, while male lions tend to move toward hyenas.”
These results challenge the long‑standing belief that hyenas simply shadow lions to scavenge leftovers. Instead, the study suggests that lions are the active trackers in many encounters, asserting dominance in the shared landscape.
Methodology
Collars recorded location fixes every five minutes during peak activity hours. Researchers identified 23 simultaneous animal pairs, including ten lion‑hyena pairs, and classified each interaction as moving toward, away from, or sideways relative to the other animal. Thousands of such paired fixes allowed the team to detect robust statistical trends.
While male lions showed a strong tendency to approach, female lions were more ambivalent, with their responses varying depending on the presence of other pride members. Barker cautioned that the sample size remains modest and that some finer‑scale findings should be viewed as trends rather than definitive conclusions.
Implications
Understanding these movement dynamics helps clarify how top predators negotiate space, risk, and reward in the African savanna. Barker hopes future research will expand the approach to other carnivores, linking movement patterns directly to survival and reproductive success.
“If I had unlimited resources, I would love to extend this approach to other members of the carnivore guild,” Barker said, emphasizing the broader goal of connecting behavior to the factors that determine which animals thrive.
