Bollons Island
Bollons Island () is a small island in New Zealand's subantarctic Antipodes Islands group. It is the second largest island in the group behind Antipodes Island. Geography The island is roughly crescent-shaped, and has an area of . It lies to the northeast of the group's main island, Antipodes Island, separated from it by a 1.2 kilometre wide strait. The smaller Archway Island lies immediately to the northwest of Bollons Island. Bollons Island is dominated by a curved ridge running the length of the island, with a highest point above sea level. Cliffs surround the island on all sides except the west. History The island is named after John Bollons, Master of the New Zealand Marine Department vessels, NZGSS ''Hinemoa'' and SS ''Tutanekai''. Important Bird Area The island is part of the Antipodes Islands Important Bird Area (IBA), identified as such by BirdLife International because of the significance of the group as a breeding site for several species of seabirds.BirdLife Int ...

Antipodes Island
In geography, the antipode () of any spot on Earth is the point on Earth's surface diametrically opposite to it. A pair of points ''antipodal'' () to each other are situated such that a straight line connecting the two would pass through Earth's center. Antipodal points are as far away from each other as possible. The North and South Poles are antipodes of each other. In the Northern Hemisphere, "the Antipodes" may refer to Australia and New Zealand, and Antipodeans to their inhabitants. Geographically, the antipodes of the British Isles are in the Pacific Ocean, south of New Zealand. This gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipode of London. The antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, France and Morocco are antipodal to New Zealand. Approximately 15% of land territory is antipodal to other land, representing approximately 4.4% of Earth's surface. Another source estimates that ...

Reischek's Parakeet
Reischek's parakeet (''Cyanoramphus hochstetteri'') is a small green parrot confined to Antipodes Island, one of New Zealand’s subantarctic islands, which it shares with a congener, the larger Antipodes parakeet. Taxonomy The common name commemorates pioneering naturalist and collector Andreas Reischek, who collected specimens of the parrot in 1888 and who named it ''Platycercus hochstetteri'' for the son of his friend, Austrian geologist Ferdinand von Hochstetter, who made a geological survey of New Zealand. Reischek’s parakeet was previously considered to be a subspecies of the red-crowned parakeet ''C. novaezelandiae'', which it resembles in appearance, but was later lumped with the Macquarie parakeet from Macquarie Island in a 2001 paper by Wee Ming Boon and others following an examination of the molecular systematics of the genus which found that many of the red-crowned parakeet subspecies should be elevated to full species.Boon, Wee Ming; Kearvell, Jonathan C.; Daug ...

Volcanoes Of The New Zealand Outlying Islands
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching an ...

Territorial Claims In Antarctica
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight land claim, territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as Spain, China, India, Italy, Japan, Pakistan, Russia, South Africa (SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom. History Spanish claims According to Argentina and Chile, the Spanish Crown had claims on Antarctica.

List Of Islands Of New Zealand
New Zealand consists of more than six hundred islands, mainly remnants of Zealandia, a larger land mass now beneath the sea. New Zealand is the List of island countries#UN member states and states with limited recognition, sixth-largest island country, and the third-largest located entirely in the Southern Hemisphere. The following is a list of islands of New Zealand. The two largest islands – where most of the population lives – have names in both English and in the Māori language. They are the North Island or ''Te Ika-a-Māui'' and the South Island or ''Te Waipounamu''. Various Māori iwi sometimes use other names, with some preferring to call the South Island ''Te Waka o Aoraki''. The two islands are separated by the Cook Strait. In general practice, the term ''mainland'' refers to the North Island and South Island. However, the South Island alone is sometimes called "the mainland" – especially by its residents, as a nickname – because it is the larger of the two ma ...

Antipodes Parakeet
The Antipodes parakeet or Antipodes Island parakeet (''Cyanoramphus unicolor'') is a parrot in the family Psittaculidae that is endemic to the Antipodes Islands of New Zealand. It is one of two parrot species found on the islands, and one of only five ground-dwelling parrots in the world. They are long-living birds that may live up to 10 years of age, but the introduction of mice that compete with them for food was a threat to their survival on the Antipodes Islands until the mice were successfully eradicated from the Islands in 2016 (confirmed 2018). Unusually for parrots, they sometimes prey upon other birds, a trait shared by another New Zealand parrot, the kea. Taxonomy The Antipodes parakeet was depicted in 1831 by English artist Edward Lear in his ''Illustrations of the Family of Psittacidae, or Parrots''. Lear used the common name "uniform parakeet" and coined the binomial name ''Platycercus unicolor''. The species is now placed in the genus ''Cyanoramphus'' that was intro ...

Seabird
Seabirds (also known as marine birds) are birds that are adaptation, adapted to life within the marine ecosystem, marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding ecological niche, niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous geological period, period, while modern seabird families emerged in the Paleogene. Seabirds generally live longer, Reproduction, breed later and have fewer young than other birds, but they invest a great deal of time in their young. Most species nest in Bird colony, colonies, varying in size from a few dozen birds to millions. Many species are famous for undertaking long annual bird migration, migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even on each other. Seabirds can be highly pelagic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Zealand
New Zealand () is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and List of islands of New Zealand, over 600 smaller islands. It is the List of island countries, sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The Geography of New Zealand, country's varied topography and sharp mountain peaks, including the Southern Alps (), owe much to tectonic uplift and volcanic eruptions. Capital of New Zealand, New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
