Research overview: scavenging and competition with hyenas

Lions are both hunters and scavengers, and their relationship with spotted hyenas is a central feature of African large-carnivore communities. This overview reviews how lions appropriate hyena kills and how hyenas mob and displace lions from carcasses, with the outcome depending on the numbers on each side and the presence of male lions. It examines the energetic significance of scavenging in lion diet, the role of vultures in revealing carcasses, and how interference competition shapes the spatial and temporal activity of both predators. The synthesis frames the lion-hyena rivalry as a defining axis of the guild, influencing kill retention, ranging, and even mortality. For safari observers it explains the noisy standoffs at carcasses where the balance of power shifts with each animal that arrives.
