⭐ Core Definition: Kea

The kea (/ˈkiːə/ KEE-ə; Māori: [kɛ.a]; Nestor notabilis) is a species of large parrot in the family Strigopidae that is endemic to the forested and alpine regions of the South Island of New Zealand. About 48 cm (19 in) long, it is mostly olive-green, with brilliant orange under its wings, and has a large, narrow, curved, grey-brown upper beak. Its omnivorous diet consists mainly of roots, leaves, berries, nectar, and insects, but also includes carrion. It was once killed for bounty due to concern by sheep farmers that it attacked livestock, especially sheep. The kea is now uncommon, and received absolute protection under the Wildlife Act in 1986.

The kea nests in burrows or crevices among the roots of trees. Kea are known for their intelligence and curiosity, both vital to their survival in a harsh mountain environment. Kea can solve logical puzzles, such as pushing and pulling things in a certain order to get to food, and will work together to achieve a certain objective. They have been filmed preparing and using tools.

👉 Kea in the context of Bird intelligence

The difficulty of defining or measuring intelligence in non-human animals makes the subject difficult to study scientifically in birds. In general, birds have relatively large brains compared to their head size. Furthermore, bird brains have two-to-four times the neuron packing density of mammal brains, for higher overall efficiency. The visual and auditory senses are well developed in most species, though the tactile and olfactory senses are well realized only in a few groups. Birds communicate using visual signals as well as through the use of calls and song. The testing of intelligence in birds is therefore usually based on studying responses to sensory stimuli.

The corvids (ravens, crows, jays, magpies, etc.) and parrots are often considered the most intelligent birds, and are among the most intelligent animals in general. Pigeons, finches, chickens, and birds of prey have also been common subjects of intelligence studies.

Kea in the context of Strigopoidea

The New Zealand parrot family, Strigopidae, consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, and probably the fossil Heracles. The genus Nestor consists of the kea, kākā, Norfolk kākā and Chatham kākā, while the genus Strigops contains the kākāpō. All extant species are endemic to New Zealand. The species of the genus Nelepsittacus were endemics of the main islands, while the two extinct species of the genus Nestor were found at the nearby oceanic islands such as Chatham Island of New Zealand, and Norfolk Island and adjacent Phillip Island.

The Norfolk kākā and the Chatham kākā have become extinct in recent times, while the species of the genus Nelepsittacus have been extinct for 16 million years. All extant species, the kākāpō, kea, and the two subspecies of the kākā, are threatened. Human activity caused the two extinctions and the decline of the other three species. Settlers introduced invasive species, such as pigs, cats, foxes, weasels, rats and possums, which eat the eggs of ground-nesting birds, and additional declines have been caused by hunting for food, killing as agricultural pests, habitat loss, and introduced wasps.
