How GPS collars & camera traps changed 'accepted wisdom' about male lions & hyenas

​​​For years, researchers have assumed a common relationship between lions and spotted hyenas on the African savannah. It's relatively simple: hyenas follow lions. The hyenas wait for the big cats to make a kill so they can take advantage of leftover food. But a new study suggests the relationship isn't as one-sided as that long-held view suggests. When lions and hyenas encounter each other, hyenas often move away while male lions move toward them.​​​The finding comes from a four-year study that combined GPS collars, camera traps and direct observations to examine how the two carnivores actually move around each other in the wild.
