Kākāpō: The rare heaviest parrot that can live up to 100 years found in New Zealand

The kākāpō (Strigops habroptilus), famously known as the "chonky parrot," is a critically endangered, flightless parrot native to New Zealand. Renowned for its nocturnal habits, moss-green plumage, and owl-like face, the kākāpō is one of the rarest and most unique birds in the world. With an extraordinary lifespan of up to 90 years or more, this nocturnal, ground-dwelling parrot has become a symbol of conservation success and wildlife protection. Efforts to save the kākāpō highlight endangered species preservation, ecological balance, and New Zealand’s unique biodiversity, making it a focal point for wildlife enthusiasts and eco-tourism.The kākāpō is the heaviest parrot species in the world, weighing between 4 to 9 pounds. Its name, derived from the Māori language, translates to “night parrot,” perfectly describing its nocturnal behaviour and preference for activity after dark. The bird’s moss-green plumage provides excellent camouflage in New Zealand’s native forests, while its owl-like facial disc and large round body give it a distinctive appearance among parrots.Although kākāpō have wings, they are flightless. Instead, these wings are adapted for balance, support, and climbing through dense forest undergrowth. Their strong legs and muscular feet allow them to move efficiently on the forest floor, forage for food, and even climb low trees or shrubs. The combination of flightlessness, nocturnal habits, and unique morphology makes the kākāpō one of the most unusual and fascinating parrots in the world, capturing the attention of bird enthusiasts, conservationists, and wildlife researchers alike.Diet and feeding habitsKākāpō are herbivores with a preference for native New Zealand plants. Their diet includes leaves, fruits, seeds, and flowers, with a particular fondness for rimu fruit, which also influences their breeding cycles. Their slow digestion and careful selection of food reflect their energy-conserving lifestyle.Nocturnal and ground-dwelling behaviourKākāpō are primarily nocturnal, feeding at night and resting during the day. Despite being flightless, they are excellent climbers, using their strong legs to move through dense forests and even climb trees. They communicate through low-frequency booming calls during mating season, which can travel over long distances.Breeding challengesKākāpō exhibit a polygynous lek mating system. Males perform booming calls to attract females. Breeding occurs only every 2-4 years, largely depending on the availability of rimu fruit. Chicks are vulnerable to predation, making conservation efforts vital for species survival.Conservation effortsHuman-introduced predators caused a severe decline in kākāpō populations, dropping to about 50 individuals in the 1990s. Conservation initiatives have included relocation to predator-free islands, intensive monitoring, supplementary feeding, and nest protection. These efforts have helped increase the population to over 240 individuals.Role in the ecosystemKākāpō contribute to forest regeneration by dispersing seeds from the fruits they consume. They help maintain plant diversity, particularly rimu and other native trees. Their foraging behaviour also aerates soil, benefiting other plant and animal species. Additionally, their seed dispersal promotes natural forest succession, supports habitat for smaller wildlife, and aids in maintaining ecological balance, ensuring that native forests remain resilient, healthy, and biodiverse for future generations while sustaining critical food sources for numerous interconnected species within their ecosystem.Research and scientific insightsStudies on kākāpō longevity help scientists understand ageing in birds. Research on their breeding patterns provides insight into polygynous lek systems, while conservation biology studies on kākāpō populations inform management strategies for other endangered species worldwide.Remarkable longevityKākāpō are among the longest-living birds on Earth. They can live 58–90 years in the wild, with some individuals potentially reaching 100 years in captivity or protected environments. Their longevity is linked to a low metabolic rate, a trait common among flightless birds. The energy conservation from not flying allows them to live longer compared to other parrots.Cultural significance and tourismKākāpō have become iconic in New Zealand ecotourism, attracting visitors eager to learn about conservation and wildlife. They also hold cultural importance for Māori communities, who used their feathers in traditional weaving and included the bird in local folklore.The kākāpō is more than a bird; it is a symbol of resilience and conservation. Its survival demonstrates the importance of protecting endangered species and the ecosystems they inhabit. Through dedicated efforts, the kākāpō has made a remarkable comeback, offering hope for other species facing similar threats.Also read | 10 fascinating facts about hummingbirds: Nature’s tiny wonders
