[41], The Department of Conservation also suggest that the time savings resulting from a more calorie-rich diet will give kea more free time to investigate and hence damage things at campsites and car parks. This bird is in need of a rescue in its journey towards survival. Breeding Kea nest mainly below the tree line, on the ground in natural cavities such as a rock crevice, the hollow base of a large tree, a hollow under the roots of a tree, a hollow log or a dirt cavity under the lip of an old river terrace. [58] Traps are also considered a risk to kea. This year, it was uplisted from Vulnerable to Endangered on the IUCN Red List. [8] Its specific epithet, the Latin term notabilis, means "noteworthy".

[52], Lead poisoning, mostly from the roofs of buildings/building materials, is also a significant cause of premature deaths among kea. [38] In August 1992, however, its nocturnal assaults were captured on video,[6][39] proving that at least some kea will attack and feed on healthy sheep. Kea are now listed as a nationally endangered species and the status of the wild Kea population remains unclear. In the case of the critically endangered Javan rhino, studies have shown that existing habitat is limited by both human encroachment and the predominance of an invasive palm species called … They will scavenge on animals that have already died, or attack sick or injured sheep. Which means it is at risk of becoming endangered. Their curiosity leads them to peck and carry away unguarded items of clothing, or to pry apart rubber parts of cars — to the entertainment and annoyance of human observers. [32] The median lifespan of a wild subadult kea has been estimated at five years, based on the proportion of kea seen again in successive seasons in Arthur's Pass, and allowing for some emigration to surrounding areas. [6][27] It has been observed breaking open shearwater nests to feed on the chicks after hearing the chicks in their nests. Introduced species coupled with the clearing of forests for agriculture and farming have had … As of May 2016, the Kea is not listed as endangered. She has a B.S. A kea checks out a parked car in Fiordland National Park. The IUCN lists Kea as Endangered. [50], A study of kea numbers in Nelson Lakes National Park showed a substantial decline in the population between 1999 and 2009, caused primarily by predation of kea eggs and chicks. Possums are known to prey on kea and disturb nests although they are not as severe a threat as stoats, and rats have also occasionally been observed preying on kea eggs. What are the threats to their existence? Its omnivorous diet includes carrion,[3] but consists mainly of roots, leaves, berries, nectar, and insects. [26], Kea are social and live in groups of up to 13 birds. Another threat to the kea include conversion of forests into pasture lands. In the 1970s, the kea received partial protection after a census counted only 5,000 birds. For example, in the late 1990s, a Fox Glacier resident killed 33 kea in the glacier car park[45] and in 2008, two kea were shot in Arthur's Pass and stapled to a sign.

The kea ranges from lowland river valleys and coastal forests of the South Island's west coast up to the alpine regions of the South Island such as Arthur's Pass and Aoraki / Mount Cook National Park, closely associated throughout its range with the southern beech (Nothofagus) forests in the alpine ridge. Kea are the protagonists in New Zealand author Philip Temple's novels Beak of the Moon (1981) and Dark of the Moon (1993), recounting respectively the first encounters of a group of kea with humans at the time of the colonisation of the South Island by Māori, and their life in present-day, human-dominated New Zealand. What Are The Threats Faced By Them? With such striking qualities and highly unique traits, it is a matter of grave concern that these apes are getting endangered. [25], At least one observer has reported that the kea is polygynous, with one male attached to multiple females. These events have been correlated with high mortality events in the kea population. Now the Kea are protected by law, but it may be too little too late. Causes of species endangerment are many, but conservation biologists recognize that multiple forces drawn along with human activity reinforce one another to cause a species to diminish. Your email address will not be published. Right to Life asks why is the life of a Kea worth more than the life a Human Child. The Kea Conservation Trust is reminding people not to feed wild birds.

[56], The 1080 pesticide is used to control invasive pest mammals such as stoats and possums and has also been implicated in kea deaths. Sheep suffering from unusual wounds on their sides or loins were noticed by the mid-1860s, within a decade of sheep farmers moving into the high country. They are accessed by tunnels leading back 1 to 6 metres (3.3 to 19.7 ft) into a larger chamber, which is furnished with lichens, moss, ferns, and rotting wood. The Asian elephant was listed as Endangered under the U.S. [47], A gathering or group of kea is called a circus. [39][20], There are also anecdotal reports of kea attacking rabbits, dogs, and even horses. So these are the reasons why the sea turtles are endangered. Now uncommon, the kea was once killed for bounty due to concerns by the sheep-farming community that it attacked livestock, especially sheep. It first appeared on the IUCN Red List of Threatened Species in 2000 as vulnerable. Though the bird does not directly kill the sheep, death can result from infections or accidents suffered by animals when trying to escape. [11][12][13][14] Together, they form the parrot superfamily Strigopoidea, an ancient group that split off from all other Psittacidae before their radiation. The kea featured on the reverse side of the New Zealand $10 note between 1967 and 1992, when it was replaced with the whio. The kea is the only parrot in the word that is considered alpine, meaning it resides in high mountainous areas. [19][20], The population was estimated at between 1,000 and 5,000 individuals in 1986,[21] contrasting with another estimate of 15,000 birds in 1992. The kea was described by ornithologist John Gould in 1856. Curiousity. [62], Some are calling for keas to be reintroduced into predator-free zones in the North Island. Human impact is the biggest threat to their existence right now. [55] Research conducted by Victoria University in 2008 confirmed that the natural curiosity of kea which has enabled the species to adapt to its extreme environment, may increase its propensity to poisoning through ingestion of lead – i.e. For instance, in 1962, animal specialist J.R. Jackson concluded, while the bird may attack sick or injured sheep, especially if it mistook them for dead, it was not a significant predator. [22] The oldest known captive kea was 50 years old in 2008. Why are Raccoons Endangered on Cozumel?

Various theories, including similarities with existing food sources, curiosity, entertainment, hunger, maggots as well as a progression from scavenging dead sheep and hides have all been put forward as to how the behaviour was first acquired. [61], A citizen science project called the "Kea Database" was launched in 2017 that allows for the recording of kea observations to an online database. SHARE. Kea are endemic to the South Island of New Zealand and are closely associated with mountain beech and lowland podocarp forests. Despite being classified as Nationally Endangered in the New Zealand Threat Classification System[60] and endangered in the IUCN Red List and protected by law, kea are still deliberately shot. Their range extends approximately 3.5 million hectares from the far north-western forests in Kahurangi National Park and Abel Tasman to the far south-western reaches of Fiordland.

It has a short, broad, bluish-green tail with a black tip. [37] There are also suggestions that Kea used to feed on Moa in a similar way.[39]. The government agreed to investigate any reports of problem birds and have them removed from the land. [51] Video cameras set up to monitor kea nests in South Westland showed that possums killed kea fledglings. More than 75% of the traps had been sprung.[59]. The video confirmed what many scientists had long suspected: that the kea uses its powerful, curved beak and claws to rip through the layer of wool and eat the fat from the back of the animal. [35] Thomas Potts noted that attacks were most frequent during winter and snow-bound sheep with two years growth in their fleece were the most vulnerable, while newly-shorn sheep in warm weather were rarely molested. . Its omnivorous diet includes carrion, but consists mainly of roots, leaves, berries, nectar, and insects. (1999) Kea.

Before the 1900s, tiger populations in the wild were probably over 100,000 animals with 9 subspecies. People commonly encounter wild kea at South Island ski areas, where they are attracted by the prospect of food scraps. For example, seven kea were found dead following an aerial possum control operation using 1080, at Fox Glacier in July 2008[57] and a further seven had been found dead in August 2011, following a 1080 aerial possum control operation in Ōkārito Forest. According to the World Wildlife Fund (WWF), the number of tigers has already decreased by 95% and the percent survival of tigers in the regions they resided ten years ago has reduced by 40%. Every year 60 per cent of kea nests are devastated by predators such as … Breeding at heights of 1,600 metres (5,200 ft) above sea level and higher, it is one of the few parrot species in the world to regularly spend time above the tree line. All four are thought to stem from a "proto-kākā", dwelling in the forests of New Zealand five million years ago. And if you ask us, these causes are totally avoidable, only if we are willing to work on them collectively. The large, green parrot had been listed as Vulnerable, but recent studies show that their populations are declining rapidly and has resulted in an “Endangered” status. [17] The male is about 5% longer than the female, and the male's upper beak is 12–14% longer than the female's. They declared it a favorable area and settled. Indian Elephants are currently endangered. They use the acronym HIPPO for Habitat destruction, Invasive species, Pollution, Population and Overharvesting. [54] Additional analysis of 15 dead kea sent to Massey University for diagnostic pathology between 1991 and 1997 found 9 bodies to have lead blood levels consistent with causing death. [42], The birds' naturally trusting behaviour around humans has also been indicated as a contributing factor in a number of recent incidents at popular tourist spots where kea have been purposely killed. Juveniles will be considered of breeding age after 3 years. Email. [37][49][20] It was intended that hunters would kill kea only on the farms and council areas that paid the bounty, but some hunted them in national parks and in Westland, where they were officially protected.
