Kakapos (Strigops habroptila) have a relatively long lifespan compared to many other bird species. In the wild, they have been known to live for several decades. The estimated lifespan of a kakapo in the wild is around 60 to 90 years. However, it's important to note that the lifespan of individual kakapos can vary depending on various factors such as their health, habitat conditions, and availability of food resources.
Kakapos have evolved to be long-lived birds, and their extended lifespan is believed to be a result of their slow reproductive rate, late sexual maturity, and low predation pressure. Their long lifespan allows them to have a greater chance of breeding multiple times throughout their lives, contributing to the survival of their species.
