Abbott's Booby
Abbott's booby (''Papasula abbotti'') is an endangered seabird of the sulid family, which includes gannets and boobies. It is a large booby and is placed within its own monotypic genus. It was first identified from a specimen collected by William Louis Abbott, who discovered it on Assumption Island in 1892. Abbott's booby breeds only in a few spots on the Australian territory of Christmas Island in the eastern Indian Ocean, although it formerly had a much wider range. It has white plumage with black markings, and is adapted for long-distance flight. It forages around Christmas Island, often around nutrient-rich oceanic upwellings, although individuals can travel for thousands of kilometres. Pairs mate for life and raise one chick every two or three years, nesting near the top of emergent trees in the rainforest canopy. The population is decreasing. Historically, much of its former habitat was logged to make way for phosphate mining. Some logging continues, and the effects of t ...

Storrs Olson
Storrs Lovejoy Olson (April 3, 1944 – January 20, 2021) was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii.

Glorioso Islands
The Glorieuses or Glorioso Islands (french: Îles Glorieuses or officially also ) are a group of French islands and rocks totaling . They are controlled by France as part of the Scattered Islands in the Indian Ocean in the French Southern and Antarctic Lands, a French overseas territory, but are also claimed by Comoros, Madagascar and formerly by Seychelles. They are geographically part of the Comoro Islands between the French overseas region of Mayotte and the nation of Madagascar.

They form part of a coral reef and lagoon. Grande Glorieuses is roughly circular and measures about across. It is thickly vegetated, mainly by the remains of a coconut plantation and casuarina trees. Île du Lys, located at about northeast of Grande Glorieuses, is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Bryan Nelson
Joseph Bryan Nelson MBE FRSE (14 March 1932 – 29 June 2015) was a British ornithologist, environmental activist and academic. He was a prominent authority on seabirds, publishing numerous books and articles on gannets, cormorants and other species, teaching zoology at the University of Aberdeen, and conducting pioneering ornithological research in Jordan, Christmas Island and the Galápagos Islands.

Bird Egg
Bird eggs are laid by the females and range in quantity from one (as in condors) to up to seventeen (the grey partridge). Clutch size may vary latitudinally within a species. Some birds lay eggs even when the eggs have not been fertilized; it is not uncommon for pet owners to find their lone bird nesting on a clutch of infertile eggs, which are sometimes called wind-eggs. Anatomy All bird eggs contain the following components: * The embryo is the immature developing chick * The amnion is a membrane that initially covers the embryo and eventually fills with amniotic fluid, provides the embryo with protection against shock from movement * The allantois helps the embryo obtain oxygen and handles metabolic waste * The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo * The vitellus, or yolk, is the nutrient-bearing portion of the egg, containing most of its fat, minerals, and many of its proteins and blood vessels * The alb ...

Trade Wind
The trade winds or easterlies are the permanent east-to-west prevailing winds that flow in the Earth's equatorial region. The trade winds blow mainly from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, strengthening during the winter and when the Arctic oscillation is in its warm phase. Trade winds have been used by captains of sailing ships to cross the world's oceans for centuries. They enabled colonial expansion into the Americas, and trade routes to become established across the Atlantic Ocean and the Pacific Ocean. In meteorology, they act as the steering flow for tropical storms that form over the Atlantic, Pacific, and southern Indian oceans and make landfall in North America, Southeast Asia, and Madagascar and East Africa. Shallow cumulus clouds are seen within trade wind regimes and are capped from becoming taller by a trade wind inversion, which is caused by descending air aloft from within the subtropical ridge.

Planchonella Nitida
''Planchonella duclitan'' is a species of plant in the family Sapotaceae. A tree that may attain a height of 40 meters, presenting glossy leaves and orange fruit. It is common on Christmas Island, dominating up to 20% of the upper leaf canopy, as a tree to 30 meters, in established forest or around 40% in regenerating habitat where it may attain the maximum height.

Red-footed Booby
The red-footed booby (''Sula sula'') is a large seabird of the booby family, Sulidae. Adults always have red feet, but the colour of the plumage varies. They are powerful and agile fliers, but they are clumsy in takeoffs and landings. They are found widely in the tropics, and breed colonially in coastal regions, especially islands. The species faces few natural or man-made threats, although its population is declining; it is considered to be a least-concern species by the International Union for Conservation of Nature (IUCN). Taxonomy The first formal description of the red-footed booby was by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his ''Systema Naturae''. He introduced the binomial name ''Pelecanus sula''. The type locality is Barbados in the West Indies. The present genus ''Sula'' was introduced by the French scientist Mathurin Jacques Brisson in 1760. The word ''Sula'' is Norwegian for a gannet. There are three subspecies: * ''S. s. sula'' ...
