Attempts to protect kakapo from introduced predators by transferring them to Resolution Island in the s failed when stoats swam to the island. However, the population did not start to increase until kiore were removed from the islands and the birds were more intensively managed. Intensive management comprised moving the birds between islands, protecting nests from rats, supplementary feeding adults, closely monitoring eggs and chicks, and rescuing and hand-raising any failing chicks. Kakapo have very low genetic diversity and, as a consequence, low fertility.
Much recent conservation management has focussed on managing matings, and using artificial insemination to minimise further genetic loss. Kakapo are currently held on three islands Whenua Hou, Anchor Island and Hauturu ; they bred on all three islands in , with 32 chicks surviving. Kakapo breed in summer and autumn, but only in years of good fruit abundance. On islands in southern New Zealand they breed when the rimu trees fruit, which is once every 2 to 4 years.
Elsewhere in New Zealand they probably nested when southern beech seeded, but the triggers for breeding in some northern places, including Hauturu, are unknown. Kakapo are lek breeders. Males call from track-and-bowl systems to attract females for mating.
Males play no part in incubation or chick-rearing. The nests are on or under the ground in natural cavities or under dense vegetation. The eggs are laid in a shallow depression in the soil or rotten wood, which is repeatedly turned-over before and during incubation. Kakapo are nocturnal and solitary, occupying the same home range for many years. They forage on the ground and climb high into trees. They often leap from trees and flap their wings, but at best manage a controlled plummet. Kakapo are entirely vegetarian.
Their diet includes, leaves, buds, flowers, fern fronds, bark, roots, rhizomes, bulbs, fruit and seeds. Diet varies seasonally. Atkinson, I. Notornis 53 : Ballance, A.

Although the majority of birds utilize their gizzards for these chewing purposes, kakapos' gizzards are rather futile. Once a kakapo is through feeding on something, he will leave behind a conspicuous and fibrous chew mass that has a crescent form -- a direct result of his soaking up all of a plant's nourishment.

Rimu Tree Fruit Preference Although kakapos readily eat a wide array of plants and fruits such as berries, their true meal preference lies in the rimu tree's fruit. Eating Styles of the Kakapo Kakapos possess specialized beaks that enable them to pulverize their sustenance within their mouths. Characteristics of the Central American Spider Monkey. Is a Red Panda a Herbivore or an Omnivore? Their primary difference is in size. Basically, this bird looks like a fat version of the kea.
This bird measures about two feet long and weighs a whopping seven or eight pounds. Instead of lumbering heavily through the air, this species walks horizontally along the ground.
However, when alarmed this species stands upright to face its attacker. As parrots go, Kakapos are quite noteworthy. These birds hold several records, and truly are one of a kind. Learn what makes these birds so unique below. Before European arrival, these birds lived throughout New Zealand in various habitat types. Unfortunately, nowadays these birds only live on three small islands off the coast of New Zealand and only occupy the forest habitats present there. The various habitats that they can live in include scrub forest, temperate forest, coastal regions, and more.
Researchers initiated their arrival on these islands in an attempt to save the species. The researchers relocated all remaining individuals on the mainland South Island to the offshore islands to save them from invasive species. This bird is entirely herbivorous, which means that they only eat plants.
Their diet is incredibly variable, and they feed on fruits, nuts, berries, seeds, leaves, shoots, and more. Even though they cannot fly, they do forage in trees and they are quite competent climbers. Unlike most species of birds, Kakapos have relatively underdeveloped gizzards.
Instead of using their gizzard to grind and digest food, this species uses their beaks and tongues to grind their food. Humans single-handedly decimated the populations of the Kakapo.
Before humans arrived on New Zealand this bird thrived, even against natural predators like eagles and falcons.
