Bocage's Akalat
Bocage's akalat (''Sheppardia bocagei'') is a species of bird in the family Muscicapidae. It is found in Angola, Cameroon, Democratic Republic of the Congo, Equatorial Guinea, Nigeria, Tanzania, and Zambia. Its natural habitats are boreal forests, subtropical or tropical dry forests, subtropical or tropical swamps, and subtropical or tropical moist montane forests. The common name and Latin binomial commemorate the Portuguese naturalist José Vicente Barbosa du Bocage. The short-tailed akalat (''S. poensis'') or Alexander's akalat was formerly considered conspecific, but was split as a distinct species by the IOC in 2021. This species' name commemorates Boyd Alexander, an English ornithologist Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them."

Otto Finsch
Friedrich Hermann Otto Finsch (8 August 1839, Warmbrunn – 31 January 1917, Braunschweig) was a German ethnographer, naturalist and colonial explorer. He is known for a two-volume monograph on the parrots of the world which earned him a doctorate. He also wrote on the people of New Guinea and was involved in plans for German colonization in Southeast Asia. Several species of bird (such as '' Oenanthe finschii'', '' Alophoixus finschii'', '' Psittacula finschii'') are named after him as also the town of Finschhafen in Morobe Province, Papua New Guinea and a crater on the moon. Biography Finsch was born at Bad Warmbrunn in Silesia to Mortiz Finsch and Mathilde née Leder. His father was in the glass trade and he too trained as a glass painter. An interest in birds led him to use his artistic skills for the purpose. Finsch went to Budapest in 1857 and studied at the Royal Hungarian University, earning money by preparing natural history specimens. He then spent two years in Russe, ...

Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates periodic inundatio ...

Birds Of Southern Africa
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimmi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Boyd Alexander
Lieutenant Boyd Alexander (16 January 1873 – 2 April 1910) was an English officer in the British Army, as well as an explorer and ornithologist. Early life Boyd was the oldest son (with a twin brother) of Lt Colonel Boyd Francis Alexander. On his mother's side he was the grandson of David Wilson, the founder of the Great Eastern Hotel in Calcutta. He was born at Swifts Park at Cranbrook in Kent and educated at Radley and Sandhurst. Alexander was commissioned in a Militia battalion of the Rifle Brigade (Prince Consort's Own), and in October 1900 took up a commission in a regular battalion of that regiment. Promotion to lieutenant followed on 22 January 1902. During 1902 he visited the Gold Coast Colony, where he made an ornithological survey of that colony, and in September that year he left for the Bonin Islands to investigate their avifauna. African expedition Lieutenant Alexander was a member of an expedition which travelled across Africa from the Niger to the Ni ...

International Ornithologists' Union
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees. International Ornithological Congress The International Ornithological Congress series forms the oldest and largest international series of meetings of ornithologists. It is organised by the International Ornithologists' Union. The first meeting was in 1884; subsequent meetings were irregular until 1926 since when meetings have been held every four years, except for two missed meetings during and in the immediate aftermath of the Second World War World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945.

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in ...
