Short answer
The average lifespan of a kiwi is typically around 25-30 years.
Life expectancy
The average lifespan of a kiwi, a flightless bird native to New Zealand, varies depending on the species. There are five recognized species of kiwis: the North Island brown kiwi, the great spotted kiwi, the little spotted kiwi, the rowi kiwi, and the tokoeka kiwi. On average, most kiwi species have a lifespan ranging between 25 to 50 years.
The North Island brown kiwi is the most common species, and they typically live for about 25 to 30 years in the wild. However, in captivity, with proper care and protection from predators, they can live up to 50 years. The great spotted kiwi has a similar lifespan, averaging around 25 to 40 years in the wild.
The little spotted kiwi has a relatively shorter lifespan, ranging between 25 to 30 years in the wild. This species was once abundant but has experienced a decline in numbers, making them vulnerable to extinction. The rowi kiwi and the tokoeka kiwi have slightly longer lifespans, averaging around 40 to 50 years. These two species are also considered threatened and are the rarest of all kiwi species.
It is important to note that these are just average figures, and individual kiwis may live shorter or longer lives depending on various factors such as predation, habitat quality, and ecological pressures. Efforts are being made in New Zealand to protect these iconic birds and ensure their survival for future generations to enjoy.
Some interesting facts about Kiwi
- Kiwi is not just a fruit, but also refers to a flightless bird native to New Zealand.
- The kiwi bird is the national symbol of New Zealand, representing its unique wildlife.
- Kiwi birds are nocturnal and have a keen sense of smell, using their long beaks to search for food, such as insects, worms, and berries.

Summary
The lifespan of a kiwi bird varies depending on the species, with some living up to 20-40 years in the wild and even longer in captivity. The North Island brown kiwi has an average lifespan of 14-20 years, while the smaller species like the little spotted kiwi and rowi can live up to 20-40 years. Factors such as habitat, predation, reproductive success, and human interaction can greatly influence the lifespan of kiwis. Overall, these unique and endangered birds have the potential to live a relatively long life if they are successfully protected and conserved.
