South-west Saint Helena Important Bird Area
The South-west Saint Helena Important Bird Area is a 45 km2 tract of land covering about 37% of the island of Saint Helena, a British Overseas Territory in the South Atlantic Ocean. It has been identified by BirdLife International as an Important Bird Area (IBA) because it supports several colonies of breeding seabirds, including the red-billed tropicbird, as well as habitat of the endemic, and critically endangered, Saint Helena plover. Description The site covers south-western Saint Helena, from Diana's Peak National Park to the mainly basaltic islets of Egg, Speery and Peaked Islands and other offshore stacks and rocks which support the seabird colonies. The four vegetation zones comprise an arid, eroded lowland below 350 m, an intermediate zone at 350–500 m of pasture and non-indigenous woodland, a moist highland zone characterised by woodland and flax plantations and, at the highest point of the island, a small remnant area of native ''Dicksonia'' f ...

Phaethon Aethereus Little Tobago
Phaethon (; grc, Φαέθων, Phaéthōn, ), also spelled Phaëthon, was the son of the Oceanid Clymene and the sun-god Helios in Greek mythology. According to most authors, Phaethon is the son of Helios, and out of desire to have his parentage confirmed, travels to the sun-god's palace in the east. There he is recognised by his father, and asks him for the privilege to drive his chariot for a single day. Despite Helios' fervent warnings and attempts to talk him out of it, counting the numerous dangers he would face in his celestial journey and reminding Phaethon that only he can control the horses, the boy is not dissuaded and does not change his mind. He is then allowed to take the chariot's reins; his ride is disastrous, as he cannot keep a firm grip on the horses. As a result, he drives the chariot too close to the earth, burning it, and too far from it, freezing it. In the end, after many complaints, from the stars in the sky to the earth itself, Zeus strikes Phaethon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phormium Tenax
''Phormium tenax'' (called flax in New Zealand English; in Māori; New Zealand flax outside New Zealand; and New Zealand hemp in historical nautical contexts) is an evergreen perennial plant native to New Zealand and Norfolk Island that is an important fibre plant and a popular ornamental plant.Roger Holmes and Lance Walheim. 2005. ''California Home Landscaping'', Creative Homeowner Press The plant grows as a clump of long, straplike leaves, up to two metres long, from which arises a much taller flowering shoot, with dramatic yellow or red flowers. The fibre has been widely used since the arrival of Māori to New Zealand, originally in Māori traditional textiles and also in rope and sail making after the arrival of Europeans until at least WWII. It is an invasive species in some of the Pacific Islands and in Australia. The blades of the plant contain cucurbitacins, which are poisonous to some animals, and some of them are among the bitterest tastes to humans. Etymology The ...

North-east Saint Helena Important Bird Area
The North-east Saint Helena Important Bird Area is a 48 km2 tract of land covering about 39% of the island of Saint Helena, a British Overseas Territory in the South Atlantic Ocean. It has been identified by BirdLife International as an Important Bird Area (IBA) because it supports several colonies of breeding seabirds, including the red-billed tropicbird, as well as much of the remaining habitat of the endemic, and critically endangered, Saint Helena plover. Description The site covers north-eastern Saint Helena, from the eastern end of Diana's Peak National Park to the basaltic stacks of Shore Island, George Island and other offshore rocks which support the seabird colonies. The three vegetation zones comprise an arid, eroded lowland below 350 m, an intermediate zone at 350–500 m of pasture and non-indigenous woodland, and a moist highland zone characterised by woodland and flax plantations. The coast is dominated by sea cliffs rising mainly to between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Booby
The brown booby (''Sula leucogaster'') is a large seabird of the booby family Sulidae, of which it is perhaps the most common and widespread species. It has a pantropical range, which overlaps with that of other booby species. The gregarious brown booby commutes and forages at low height over inshore waters. Flocks plunge-dive to take small fish, especially when these are driven near the surface by their predators. They only nest on the ground, and roost on solid objects rather than the water surface. Taxonomy The brown booby was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his ''Histoire Naturelle des Oiseaux'' in 1781. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the ''Planches Enluminées D'Histoire Naturelle'' which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Buffon did not include a scientific name with his description but in 1783 the Dutch naturalist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Tern
The white tern or common white tern (''Gygis alba'') is a small seabird found across the tropical oceans of the world. It is sometimes known as the fairy tern, although this name is potentially confusing as it is also the common name of '' Sternula nereis''. Other names for the species include angel tern and white noddy in English, and manu-o-Kū in Hawaiian. The little white tern ('' Gygis microrhyncha''), previously considered a subspecies of the white tern (''Gygis alba microrhyncha''), is now recognised as a separate species. Taxonomy The white tern was first formally described by the Swedish naturalist Anders Sparrman in 1786 under the binomial name ''Sterna alba''. The genus ''Gygis'' was introduced by the German zoologist Johann Georg Wagler in 1832. The name ''Gygis'' is from the Ancient Greek for a mythical bird and the specific is Latin for "white". Molecular phylogenetic studies have shown that the white tern is more closely related to the noddies than it is to th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Noddy
The black noddy or white-capped noddy (''Anous minutus'') is a seabird from the family Laridae. It is a medium-sized species of tern with black plumage and a white cap. It closely resembles the lesser noddy (''Anous tenuirostris'') with which it was at one time considered conspecific. The black noddy has slightly darker plumage and dark rather than pale lores. Taxonomy The black noddy was first formally described by German naturalist and lawyer Friedrich Boie in 1844 under its current binomial name. The genus name ''Anous'' is ancient Greek for "stupid" or "foolish". The specific name ''minutus'' is the Latin for "small". There are seven subspecies: *''A. m. worcesteri'' (McGregor, 1911) – Cavilli Island and Tubbataha Reef ( Sulu Sea) *''A. m. minutus'' Boie, 1844 – northeast Australia and New Guinea to Tuamotu Archipelago *''A. m. marcusi'' (Bryan, 1903) – Marcus and Wake Islands through Micronesia to the Caroline Islands *''A. m. melanogenys'' Gray, 1846 – Hawaiian I ...

Brown Noddy
The brown noddy or common noddy (''Anous stolidus'') is a seabird in the family Laridae. The largest of the noddies, it can be told from the closely related black noddy by its larger size and plumage, which is dark brown rather than black. The brown noddy is a tropical seabird with a worldwide distribution, ranging from Hawaii to the Tuamotu Archipelago and Australia in the Pacific Ocean, from the Red Sea to the Seychelles and Australia in the Indian Ocean and in the Caribbean to Tristan da Cunha in the Atlantic Ocean. The brown noddy is colonial, usually nesting on elevated situations on cliffs or in short trees or shrubs. It only occasionally nests on the ground. A single egg is laid by the female of a pair each breeding season. In India, the brown noddy is protected in the PM Sayeed Marine Birds Conservation Reserve. Taxonomy The first formal description of the brown noddy was by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' u ...

Sooty Tern
The sooty tern (''Onychoprion fuscatus'') is a seabird in the family Laridae. It is a bird of the tropical oceans, returning to land only to breed on islands throughout the equatorial zone. Taxonomy The sooty tern was described by Carl Linnaeus in 1766 as ''Sterna fuscata'', bearing this name for many years until the genus ''Sterna'' was split up. It is now known as ''Onychoprion fuscatus''. The genus name is from ancient Greek , "claw" or "nail", and , "saw". The specific ''fuscatus'' is Latin for "dark". Colloquially, it is known as the wideawake tern or just wideawake. This refers to the incessant calls produced by a colony of these birds, as does the Hawaiian name ''ʻewa ʻewa'' which roughly means "cacophony". In most of Polynesia its name is ''manutara'' or similar – literally "tern-bird", though it might be better rendered in English as "the tern" or "common tern". This refers to the fact that wherever Polynesian seafarers went on their long voyages, they usuall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masked Booby
The masked booby (''Sula dactylatra''), also called the masked gannet or the blue-faced booby, is a large seabird of the booby and gannet family, Sulidae. First described by the French naturalist René-Primevère Lesson in 1831, the masked booby is one of six species of booby in the genus '' Sula''. It has a typical sulid body shape, with a long pointed yellowish bill, long neck, aerodynamic body, long slender wings and pointed tail. The adult is bright white with black wings, a black tail and a dark face mask; at long, it is the largest species of booby. The sexes have similar plumage. This species ranges across tropical oceans, except in the eastern Atlantic and eastern Pacific. In the latter, it is replaced by the Nazca booby (''Sula granti''), which was formerly regarded as a subspecies of masked booby. Nesting takes place in colonies, generally on islands and atolls far from the mainland and close to deep water required for foraging. Territorial when breeding, the masked ...

Band-rumped Storm Petrel
The band-rumped storm petrel, Madeiran storm petrel, or Harcourt's storm petrel (''Hydrobates castro'') is of the storm petrel family Hydrobatidae. Description The band-rumped storm petrel is 19–21 cm in length with a 43–46 cm wingspan, and weighs 44–49 g. It is mainly brownish black with an extensive white rump. Similar to Leach's storm petrel with the forked tail, long wings, but Leach's has a more deeply forked tail, a differently shaped (V-shaped or triangular) white rump, and a 'tern-like' flight, whereas the band-rumped storm-petrel has a more 'shearwater-like' flight. Distribution The species breeds on islands in the warmer parts of the Atlantic and Pacific Oceans. These include the Berlengas (a few tens of kilometres off mainland Portugal), the Azores, Madeira, Canary Islands and Saint Helena in the Atlantic, and in the Pacific off eastern Japan, on Kauai, Hawaii, and on the Galápagos Islands. In 2018, the species was reported to have also starte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guano
Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
