Sacred Ibis
The African sacred ibis (''Threskiornis aethiopicus'') is a species of ibis, a wading bird of the family Threskiornithidae. It is native to much of Africa, as well as small parts of Iraq, Iran and Kuwait. It is especially known for its role in the religion of the Ancient Egyptians, where it was linked to the god Thoth. The species is currently extirpated from Egypt. Taxonomy It is very closely related to the black-headed ibis and the Australian white ibis, with which it forms a superspecies complex, so much so that the three species are considered conspecific by some ornithologists. In mixed flocks these ibises often hybridise. The Australian white ibis is often called the sacred ibis colloquially. Although known to the ancient civilisations of Greece, Rome and especially Africa, ibises were unfamiliar to western Europeans from the fall of Rome until the 19th century, and mentions of this bird in the ancient works of these civilisations were supposed to describe some ...

Ethiopia
Ethiopia, , om, Itiyoophiyaa, so, Itoobiya, ti, ኢትዮጵያ, Ítiyop'iya, aa, Itiyoppiya officially the Federal Democratic Republic of Ethiopia, is a landlocked country in the Horn of Africa. It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period. Southwestern Ethiopia has been proposed as a possible homeland of the Afroasiatic la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biological Specificity
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' '' Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malagasy Sacred Ibis
The Malagasy sacred ibis (''Threskiornis bernieri'') is a relatively large, heavily built ibis endemic to the west coast of Madagascar, and Aldabra on the Seychelles. Taxonomy and systematics The Malagasy sacred ibis was formerly considered a subspecies of the African sacred ibis.Holyoak D. 1970. Comments on the classification of the Old World ibises. Bulletin of the British Ornithologists' Club 90: 67-73.Hancock JA, Kushlan JA, Kahl MP. 1992. Storks, Ibises and Spoonbills of the World. Academic Press. It is now however classified as a separate species from the African sacred ibis due to considerable differences observed in the former’s ecology and morphology.Andrianarimisa A, Razafimanjato G. 2010.

Wood Stork
The wood stork (''Mycteria americana'') is a large American wading bird in the family Ciconiidae (storks), the only member of the family to breed in North America. It was formerly called the "wood ibis", though it is not an ibis. It is found in subtropical and tropical habitats in the Americas, including the Caribbean. In South America, it is resident, but in North America, it may disperse as far as Florida. Originally described by Carl Linnaeus in 1758, this stork likely evolved in tropical regions. The head and neck are bare of feathers, and dark grey in colour. The plumage is mostly white, with the exception of the tail and some of the wing feathers, which are black with a greenish-purplish sheen. The juvenile differs from the adult, with the former having a feathered head and a yellow bill, compared to the black adult bill. There is little sexual dimorphism. The wood stork's habitat can vary, but it must have a tropical or subtropical climate with fluctuating water levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Gray
George Robert Gray FRS (8 July 1808 – 6 May 1872) was an English zoologist and author, and head of the ornithological section of the British Museum, now the Natural History Museum, in London for forty-one years. He was the younger brother of the zoologist John Edward Gray and the son of the botanist Samuel Frederick Gray. George Gray's most important publication was his ''Genera of Birds'' (1844–49), illustrated by David William Mitchell and Joseph Wolf, which included 46,000 references. Biography He was born in Little Chelsea, London, to Samuel Frederick Gray, naturalist and pharmacologist, and Elizabeth (née Forfeit), his wife. He was educated at Merchant Taylor's School. Gray started at the British Museum as Assistant Keeper of the Zoology Branch in 1831. He began by cataloguing insects, and published an ''Entomology of Australia'' (1833) and contributed the entomogical section to an English edition of Georges Cuvier's ''Animal Kingdom''. Gray described many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Le Règne Animal
''Le Règne Animal'' (The Animal Kingdom) is the most famous work of the French naturalist Georges Cuvier. It sets out to describe the natural structure of the whole of the animal kingdom based on comparative anatomy, and its natural history. Cuvier divided the animals into four ''embranchements'' ("Branches", roughly corresponding to phyla), namely vertebrates, molluscs, articulated animals (arthropods and annelids), and zoophytes (cnidaria and other phyla). The work appeared in four octavo volumes in December 1816 (although it has "1817" on the title pages); a second edition in five volumes was brought out in 1829–1830 and a third, written by twelve "disciples" of Cuvier, in 1836–1849. In this classic work, Cuvier presented the results of his life's research into the structure of living and fossil animals. With the exception of the section on insects, in which he was assisted by his friend Pierre André Latreille, the whole of the work was his own. It was translated into ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophic flooding events. In this way, ...

James Bruce
James Bruce of Kinnaird (14 December 1730 – 27 April 1794) was a Scottish traveller and travel writer who confirmed the source of the Blue Nile. He spent more than a dozen years in North Africa and Ethiopia and in 1770 became the first European to trace the origins of the Blue Nile from Egypt and Sudan. Early life James Bruce was born at the family seat of Kinnaird, Stirlingshire, and educated at Harrow School and Edinburgh University, and began to study for the bar, but his marriage to the daughter of a wine importer and merchant resulted in him entering that business instead. His wife died in October 1754, within nine months of marriage, and Bruce thereafter travelled in Portugal and Spain as part of the wine trade. The examination of oriental manuscripts at the Escorial in Spain led him to the study of Arabic and Ge'ez and determined his future career. In 1758 his father's death placed him in possession of the estate of Kinnaird. To North Africa On the outbreak of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Shaw (biologist)
George Kearsley Shaw (10 December 1751 – 22 July 1813) was an English botanist and zoologist. Life Shaw was born at Bierton, Buckinghamshire, and was educated at Magdalen Hall, Oxford, receiving his M.A. in 1772. He took up the profession of medical practitioner. In 1786 he became the assistant lecturer in botany at the University of Oxford. He was a co-founder of the Linnean Society in 1788, and became a fellow of the Royal Society in 1789. In 1791 Shaw became assistant keeper of the natural history department at the British Museum, succeeding Edward Whitaker Gray as keeper in 1806. He found that most of the items donated to the museum by Hans Sloane were in very bad condition. Medical and anatomical material was sent to the museum at the Royal College of Surgeons, but many of the stuffed animals and birds had deteriorated and had to be burnt. He was succeeded after his death by his assistant Charles Konig. Works Shaw published one of the first English descriptions with ...

Systema Naturae
' (originally in Latin written ' with the ligature æ) is one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, Linnaeus was first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ' or translated: "System of nature through the three kingdoms of nature, according to classes, orders, genera and species, with characters, differences, synonyms, places". The tenth edition of this book (1758) is considered the starting point of zoological nomenclature. In 1766–1768 Linnaeus published the much enhanced 12th edition, the last under his authorship. Another again enhanced work in the same style and titled "'" was published by Johann Friedrich Gmelin betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathurin Jacques Brisson
Mathurin Jacques Brisson (; 30 April 1723 – 23 June 1806) was a French zoologist and natural philosopher. Brisson was born at Fontenay-le-Comte. The earlier part of his life was spent in the pursuit of natural history; his published works in this field included ''Le Règne animal'' (1756) and the highly regarded ''Ornithologie'' (1760). As a young man, he was a disciple and assistant of René Antoine Ferchault de Réaumur. For a period of time he was an instructor of physical sciences and natural history to the family of the monarch. He held the chair of physics at the College of Navarre, and from 1759 was a member of the Academy of Sciences. A significant work involving the "specific weight of bodies" was his ''Pesanteur Spécifique des Corps'' (1787). In his investigations of electricity, Brisson was opposed to the theories of Priestley and Franklin. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cattle Egret
The cattle egret (''Bubulcus ibis'') is a cosmopolitan species of heron (family Ardeidae) found in the tropics, subtropics, and warm-temperate zones. It is the only member of the monotypic genus ''Bubulcus'', although some authorities regard its two subspecies as full species, the western cattle egret and the eastern cattle egret. Despite the similarities in plumage to the egrets of the genus '' Egretta'', it is more closely related to the herons of '' Ardea''. Originally native to parts of Asia, Africa, and Europe, it has undergone a rapid expansion in its distribution and successfully colonised much of the rest of the world in the last century. It is a white bird adorned with buff plumes in the breeding season. It nests in colonies, usually near bodies of water and often with other wading birds. The nest is a platform of sticks in trees or shrubs. Cattle egrets exploit drier and open habitats more than other heron species. Their feeding habitats include seasonally inunda ...
