Harrison B. Tordoff
Harrison Bruce "Bud" Tordoff (February 8, 1923 – July 23, 2008) was an American ornithologist and conservationist. He was brought up in Mechanicville in upstate New York, hunting and fishing, and became interested in wildlife management and zoology. He studied as an undergraduate at Cornell University, returning to complete his degree after a period of military service during World War II. He had served as a fighter pilot in the United States Army Air Forces, and his five confirmed aerial victories qualified him as a fighter ace. Tordoff completed his doctoral degree in ornithology at the University of Michigan. During his professional career, he worked as a faculty member and natural history museum curator at a number of public universities. Much of his career was spent at the University of Minnesota, where he served as director of the Bell Museum of Natural History from 1970 to 1983. He was active in ornithological and conservation organisations, and from 1978 to 1980 was pres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

Captain (United States O-3)
In the United States Army (), U.S. Marine Corps (USMC), U.S. Air Force (USAF), and U.S. Space Force (USSF), captain (abbreviated "CPT" in the and "Capt" in the USMC, USAF, and USSF) is a company-grade officer rank, with the pay grade of O-3. It ranks above first lieutenant and below major. It is equivalent to the rank of lieutenant in the Navy/Coast Guard officer rank system and should not be confused with the Navy/Coast Guard rank of captain. The insignia for the rank consists of two silver bars, with slight stylized differences between the Army/Air Force version and the Marine Corps version. History The U.S. military inherited the rank of captain from its British Army forebears. In the British Army, the captain was designated as the appropriate rank for the commanding officer of infantry companies, artillery batteries, and cavalry troops, which were considered as equivalent-level units. Captains also served as staff officers in regimental and brigade headquarters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Combined Bomber Offensive
The Combined Bomber Offensive (CBO) was an Allies of World War II, Allied offensive of strategic bombing during World War II, strategic bombing during World War II in Europe. The primary portion of the CBO was directed against Luftwaffe targets which was the highest priority from June 1943 to 1 April 1944. The subsequent highest priority campaigns were against V-weapon installations (June 1944) and Oil Campaign chronology of World War II, petroleum, oil, and lubrication (POL) plants (September 1944). Additional CBO targets included Transportation Plan, railyards and other transportation targets, particularly prior to the invasion of Normandy and, along with army equipment, End of World War II in Europe, in the final stages of the war in Europe. The British bombing campaign was chiefly waged by night by large numbers of heavy bombers until the latter stages of the war when German fighter defences were so reduced that daylight bombing was possible without risking large losses.

North American P-51D Mustang "Upupa Epops" Cropped
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bud Tordoff With Ground Crew In Front Of His P-51, Upupa Epops
In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual. Overview The buds of many woody plants, especially in temperate or cold climates, are protected by a covering of modified leaves called ''scales'' which tightly enclose the more delicate parts of the bud. Many bud scales are covered by a gummy substance which serves as added protection. When the bud develops, the scales may enlarge somewhat but usually just drop off, leaving a series of horizontally-elongated scars on the surface of the growing stem. By means of these scars one can determine the age of any young branch, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systematics
Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branches to further understand the relationshi ...

George Miksch Sutton
George Miksch Sutton (May 16, 1898, Bethany, Nebraska – December 7, 1982) was an American ornithologist and bird artist. He published numerous technical papers in ornithology as well as more popular works illustrated with his own art. His early artistic work was inspired and tutored by Louis Agassiz Fuertes. In 1931, he was the first ornithologist to find the eggs of the Harris's sparrow, one of the last North American birds to have its nest and eggs described. In 1935. he was part of the team of Arthur Augustus Allen during an expedition to the Singer Tract in Louisiana to make sketches of ivory-billed woodpecker. He did extensive field work in the Arctic (including Iceland), Oklahoma, Labrador, and Mexico. He received his doctorate from Cornell University and held academic posts at the University of Michigan and the University of Oklahoma, Norman. The George M. Sutton Avian Research Center in Oklahoma was named after him. His book-length works include: * ''Mexican Birds: Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Black-throated Blue Warbler
The black-throated blue warbler (''Setophaga caerulescens'') is a small passerine bird of the New World warbler family. Its breeding ranges are located in the interior of deciduous and mixed coniferous forests in eastern North America. Over the cooler months, it migrates to islands in the Caribbean and Central America. It is very rarely found in western Europe, where it is considered to be a non-indigenous species. The black-throated blue warbler is sexually dimorphic; the adult male has a black face and cheeks, deep blue upperparts and white underparts, while the adult female is olive-brown above and light yellow below. Predominantly insectivorous, the black-throated blue warbler supplements its diet with berries and seeds in winter. It builds its nests in thick shrubs and the closeness of its nesting sites to the ground make it a favored species for the study of warbler behavior in the wild. The black-throated blue warbler defends its territory against other birds of the same ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
