In the grass of the Masai Mara, two spotted hyena cubs are born in the same week, in the same den. They look identical. But one of them will eat first for the rest of her life, and the other will wait her turn at almost every meal. Nothing about the cubs decided that. Their mothers did. Follow the two cubs through their first year in a clan of a hundred: the matriarch who steps in for her daughter, the nervous "laugh" that is not laughter at all, the rank a cub inherits before she is a year old, the meal order that decides who grows fast and who grows slow, the mothers who walk seventy kilometers to the herds and back to feed their cubs, the newcomer males who queue for years instead of fighting, the whoops that carry five kilometers, and the puzzle that hyenas solved faster than chimpanzees. This story is based on real research. In spotted hyena (Crocuta crocuta) clans, adult females are larger than males and every adult female outranks every immigrant male (Kruuk, 1972; Frank, 1986). Cubs acquire the rank just below their mother through her support in early disputes, a process known as maternal rank "inheritance" (Holekamp & Smale, Behavioral Ecology and Sociobiology, 1991; Engh, Esch, Smale & Holekamp, Animal Behaviour, 2000). High-ranking females and their cubs gain priority at kills, grow faster and breed earlier (Holekamp, Smale & Szykman, 1996; Hofer & East, 2003). Males disperse from their birth clan and rise in a new clan by queuing according to tenure rather than by fighting; females prefer the longest-tenured males (East & Hofer, Behavioral Ecology, 2001; Engh et al., 2002). Serengeti mothers commute up to 70 km round trips to migratory herds and return to the communal den to nurse (Hofer & East, Animal Behaviour, 1993). The giggle encodes age and individual identity (Mathevon et al., BMC Ecology, 2010). Hyenas assess the number of unfamiliar callers from playback of whoops (Benson-Amram, Heinen, Dryer & Holekamp, Animal Behaviour, 2011), and captive pairs solved a rope-pulling cooperation task without training (Drea & Carter, Animal Behaviour, 2009). Spotted hyenas hunt most of their own food (Kruuk, 1972). Visuals in this documentary are AI-generated reconstructions of real animal behavior, based on published research and field observations. Tesa and Mira are illustrative characters. No animals were harmed, and no graphic scenes are shown.
