The kea was described by ornithologist John Gould in 1856, from two specimens shown to him by Walter Mantell, who obtained the birds in Murihiku. [10] Eight years earlier, some elderly Māori had told Mantell about the bird, and how it used to visit the coast in winter but had not been seen in recent times.
The New Zealand parrot family, Strigopidae, [1] consists of at least three genera of parrots – Nestor, Strigops, the fossil Nelepsittacus, [2] [3] and probably the fossil Heracles. [4] The genus Nestor consists of the kea , kākā , Norfolk kākā and Chatham kākā , [ 5 ] [ 6 ] while the genus Strigops contains the iconic kākāpō . [ 5 ]
Cooperative breeding, where birds other than the breeding pair help raise the young and is common in some bird families, is extremely rare in parrots, and has only unambiguously been demonstrated in the El Oro parakeet and the golden parakeet (which may also exhibit polygamous, or group breeding, behaviour with multiple females contributing to ...
The Kea Conservation Trust was incorporated in 2006 as a charitable trust, then later registered as a charity in 2008. [2] It was founded by current chairperson Tamsin Orr-Walker and three other trustees to raise money for research and to work with other community conservation groups, such as the Fiordland Wapiti Foundation.
These birds have a breeding season in spring. The Hawaii ʻakepa is the only obligate cavity-nester in Hawaii. There are no cavity-making birds in Hawaii (another honeycreeper, the ʻakiapolaʻau, drills small holes and excavates bark, but does not make holes large enough for ʻakepa nests). Thus, the ʻakepa must find naturally occurring ...
The kākā’s closest living relative is the kea; the kea and kākā became separate species 1.72 million years ago due to ecological divergence. [14] This likely occurred due to changes in the climate during the Pleistocene that drove the kākā to specialise in more forested environments and the kea to specialise in alpine and other habitats ...
So in 1999 it was declared an 'unwanted organism' under the Biosecurity Act, and a plan to remove the estimated 200 feral birds was made. [12] Live trapping of the birds was carried out. [13] The population appears under control, and there is an ongoing programme to ensure they do not establish a self-sustaining wild population. [14]
The Hawaiian coot was federally listed in October 1970 as an endangered species [7] and is considered both endemic and endangered by the state of Hawaiʻi. [8] The United States Fish and Wildlife Service's 5-year review, conducted in 2010, found that none of the four criteria established for delisting or downlisting of the species had been meet. [9]
