A forest of umbrella thorn acacia trees in northern Tanzania provides shelter and sustenance 1 for a wealth of animals. In this crowded paradise, property is hotly contested at all levels. Male impala, eager to challenge for a territory, build up strength by sparring.

The strongest male impala urges females to sample the trees in his exclusive territory. Teenage sons are not welcome. The male's breeding success depends on stamina 2 and the quality of food in his patch. The better the local menu, the longer the female stay. Impalas must nibble 3 because large thorns stop them from grabbing mouthfuls. And thorns are not the only danger.

Cheetahs 5 are masterful hunters. But an impala herd 6 has many eyes. With the cheetah 4 spotted 7 the herd runs and jumps away. Impala can leap 9 feet in the air to escape predators 8.

Once the danger is passed, the impala return and renew their struggles for territory.
