Lioness With Cubs Crossing The Road, Etosha National Park, Namibia

Group organization
Lions are predatory carnivores who manifest two types of social organization. Some are residents, living in groups, called prides. The pride usually consists of five or six related females, their cubs of both sexes, and one or two males (known as a coalition if more than one) who mate with the adult females (although extremely large prides, consisting of up to 30 individuals, have been observed). The number of adult males in a coalition is usually two, but may increase to four and decrease again over time. Male cubs are excluded from their maternal pride when they reach maturity.
The second organizational behaviour is labeled nomads, who range widely and move about sporadically, either singularly or in pairs. Pairs are more frequent among related males who have been excluded from their birth pride. Note that a lion may switch lifestyles; nomads may become residents and vice versa. Males have to go through this lifestyle and some never are able to join another pride. A female who becomes a nomad has much greater difficulty joining a new pride, as the females in a pride are related, and they reject most attempts by an unrelated female to join their family group.
