Kea

Nestor notabilis (Gould, 1856) — family Strigopidae

The world's only alpine parrot, and one of the few birds that solves problems it has never seen before.

In brief

The kea (Nestor notabilis) is the world's only alpine parrot, native to New Zealand's South Island mountains; it is highly intelligent and inventive, and is listed as Endangered largely because of introduced predators, lead poisoning and human conflict.

By the WARN Research & Conservation TeamChecked against IUCN Red List & CITES sourcesLast updated

The kea is the only parrot in the world adapted to alpine conditions, living in the mountains of New Zealand's South Island. Olive-green at rest, it flashes brilliant orange under the wings in flight. It is also, by most measures used on animals, among the most intelligent birds studied — inventive, persistent and famously destructive of anything left unattended. That curiosity is a survival trait in a harsh, food-poor environment, and it is also what puts kea in constant conflict with people. Birds strip rubber from car windscreens, open backpacks and dismantle equipment, which makes them beloved by tourists and unpopular with some residents. The species is Endangered, and much of the mortality is human-caused.

Lead poisoning from flashing and nails on old alpine buildings is a significant and entirely preventable cause of death.

Did you know?

Kea have a specific warbling play call — birds that hear a recording of it spontaneously start playing, one of the few documented contagious emotional calls outside mammals.

Key Facts: Kea

  • Kea are the only parrots adapted to alpine environments.
  • They solve novel problems, use tools in captivity and cooperate on multi-step tasks.
  • Kea have a 'play call' — hearing it prompts other birds to start playing.
  • Lead flashing and nails on old buildings poison kea, which chew soft metal.
  • Introduced stoats and possums take eggs and chicks from ground-level nests.
  • Feeding kea is harmful: it draws them to roads and buildings where most human-caused deaths occur.

Problem solvers

Kea have been shown to work through multi-step puzzles, use objects as tools in captivity, cooperate with a partner on tasks needing simultaneous action, and adjust their behaviour based on statistical information — a capacity previously demonstrated mainly in great apes. The likely driver is their environment. Alpine New Zealand offers scattered, seasonal, unpredictable food, and an animal that can work out how to open something novel does better than one that cannot. In practice this means kea investigate everything by taking it apart, which is intelligence and destruction being the same behaviour.


Play, and a call that spreads it

Kea play extensively as adults — tumbling, wrestling, tossing objects and inventing games with whatever they find. Research identified a distinct warbling call that functions as a play vocalisation: birds hearing a recording of it spontaneously begin playing, which makes it one of very few documented emotionally contagious calls outside mammals. Play in adult animals is generally associated with cognitively complex, long-lived, social species, and the kea fits all three.


Why they are Endangered

Introduced stoats and possums are the largest natural-history problem: kea nest in cavities at ground level, so eggs, chicks and brooding females are easy targets. The rest is human. Lead is a major documented poison — kea chew lead flashing, nails and head-bolts on old alpine buildings, and blood-lead levels in wild kea are high enough to cause illness and death. Vehicle strikes kill birds drawn to roadside car parks. Historically, kea were shot under a government bounty over sheep predation, and illegal killing still occurs.


Why feeding a kea harms it

Kea are engaging and will approach people readily, which makes feeding them almost irresistible. It is also one of the worst things a visitor can do. Fed birds concentrate at car parks, roadsides and buildings — precisely the places where vehicle strikes, lead exposure and conflict with residents occur. Human food is also nutritionally wrong for them, and habituated birds become bolder, which escalates property damage and the hostility that follows. The consistent conservation advice is simple: watch them, do not feed them, and secure anything you would rather keep intact.

What WARN Does

WARN publishes free, sourced species education including the cases where the most important conservation action is something a visitor chooses not to do. Kea are harmed most reliably by well-meant feeding, and that is a message education can actually shift.

If this guide helps you understand wildlife and the pressures it faces, a gift to WARN supports habitat protection and free public education in our partner countries.

How can I help save the kea?

There are three practical things that make a real difference for the kea — and the first is the one that funds everything else.

1

Fund frontline rescue

Back the partner-led teams, veterinary care and protection that reach keas where the need is greatest — WARN channels donations straight to that work.

2

Ease the pressures

Avoid the wildlife trade and souvenirs, never buy wild animals as pets, and choose sustainable, habitat-friendly products — the threats behind the kea's decline fall when demand does.

3

Spread the word

Share accurate, sourced information about the kea. Wider awareness is what turns concern into lasting protection.

Kea: Frequently Asked Questions

How can I help save the kea?

The most effective way to help the kea is to fund the frontline rescue and habitat protection that keeps the species alive — WARN channels donations to partner-led teams working where the need is greatest. You can also ease the pressures behind its decline by avoiding the wildlife trade and souvenirs, never buying wild animals as pets, and choosing sustainable products, and by sharing accurate information to build wider support. See the ways to help below, or support WARN's Support Habitat Protection.

How intelligent are kea?

Among the most capable birds studied. Kea solve multi-step puzzles, use tools in captivity, cooperate with partners on tasks needing simultaneous action, and have demonstrated statistical reasoning previously shown mainly in great apes.

Why do kea destroy things?

Investigation and destruction are the same behaviour in a kea. They live in a harsh alpine environment with scattered, unpredictable food, where taking novel objects apart is a useful strategy. Cars, backpacks and buildings are simply novel objects.

Are kea endangered?

Yes, kea are listed as Endangered. Introduced stoats and possums take eggs and chicks from ground-level nests, and lead poisoning from old alpine buildings, vehicle strikes and illegal killing add substantial human-caused mortality.

Why shouldn't you feed kea?

Feeding concentrates them at car parks, roads and buildings, which is exactly where vehicle strikes, lead exposure and conflict with residents happen. Human food is also nutritionally unsuitable, and habituated birds become bolder and more destructive.

Where do kea live?

Only in the alpine and subalpine zones of New Zealand's South Island. They are the only parrot species in the world adapted to an alpine environment.

What do keas eat?

Keas eat Omnivorous — roots, berries, insects, carrion. The kea (Nestor notabilis) is the world's only alpine parrot, native to New Zealand's South Island mountains; it is highly intelligent and inventive, and is listed as Endangered largely because of introduced predators, lead poisoning and human conflict.

Are keas dangerous?

The kea (Nestor notabilis) is the world's only alpine parrot, native to New Zealand's South Island mountains; it is highly intelligent and inventive, and is listed as Endangered largely because of introduced predators, lead poisoning and human conflict. Give wild keas space; do not corner them.

How long do keas live?

A precise wild lifespan for keas is not firmly established in the sources cited on this guide. The kea (Nestor notabilis) is the world's only alpine parrot, native to New Zealand's South Island mountains; it is highly intelligent and inventive, and is listed as Endangered largely because of introduced predators, lead poisoning and human conflict. Where longevity figures appear in the literature they vary by region, sex and whether animals are wild or captive.

How big is a kea?

A Kea is about ~48 cm. The kea (Nestor notabilis) is the world's only alpine parrot, native to New Zealand's South Island mountains; it is highly intelligent and inventive, and is listed as Endangered largely because of introduced predators, lead poisoning and human conflict. Conservation status: Stoats and possums, lead poisoning, vehicle strikes.
