Nestor Notabilis
Kea
Mountainous and forested regions, alpine and subalpine zones
The Kea, nestor notabilis, is a highly intelligent and curious parrot native to the South Island of New Zealand. Known for its striking olive-green plumage with brilliant orange underwings, the Kea is a large bird, measuring around 48 cm in length and weighing between 800 to 1,000 grams. Its strong, curved beak is well adapted for a variety of uses, from accessing food to manipulating objects. The Kea's playful and mischievous nature is matched by a keen intelligence, which has been observed in their problem-solving abilities and use of tools.
| Population: | Listed as Endangered due to declining population numbers |
| Generation Length: | 5 years |
| Average Weight: | 800-1,000 grams |
| Average Length: | 48 cm in length |
| Lifespan: | 10-15 years in the wild, can live longer in captivity |
| Diet: | Omnivorous, with seasonal variation in diet based on available resources |
| Conservation Status: | Endangered (EN) |
Keas inhabit forested and alpine regions of the South Island, where they have adapted to a harsh, variable climate. They are the world's only alpine parrot, capable of surviving in cold temperatures and snowy conditions. Keas are highly social birds, living in groups or 'flocks' that can number over a hundred individuals. Their social structure is complex, involving interactions that include cooperative play and communal problem-solving.
The diet of the Kea is omnivorous and includes leaves, berries, nectar, and insects. They are also known to scavenge on carcasses and, controversially, to prey on live sheep. This adaptability in feeding habits highlights the Kea's intelligence and opportunistic nature, allowing them to exploit various food sources throughout the year.
Reproduction for Keas occurs from July to January, with pairs forming strong bonds and often mating for life. Nests are usually located in high, inaccessible places such as rock crevices or hollow trees. Females lay 2 to 4 eggs per clutch, which are incubated for about 4 weeks. Both parents share in feeding and caring for the chicks, which fledge at around 10 to 12 weeks of age.
The population of the Kea has declined significantly, leading to its classification as 'Endangered'. Threats to the Kea include predation by introduced species, lead poisoning from human-made objects, and conflicts with humans, particularly in areas where Keas are accused of preying on livestock. Conservation efforts are focused on habitat protection, predator control, and reducing human-wildlife conflict to ensure the survival of this unique and charismatic bird.
