According to the University of Michigan, the African grey parrot has an average life expectancy of about 45 years in captivity. Some live to be as old as 60. In the wild, the life span is about 23 years.
Wild African grey parrots live in large flocks, with each family residing in its own tree. The young remain with their families for years, learning skills necessary for survival, such as recognizing toxic plants, defending territory, avoiding predators and locating water sources. Immature parrots must also learn sex-specific behaviors, including raising young and protecting nests. African grey parrots reach sexual maturity in three to five years, when they choose a partner for life.
