Ornithology
Ornithology, from Ancient Greek ὄρνις (''órnis''), meaning "bird", and -logy from λόγος (''lógos''), meaning "study", is a branch of zoology dedicated to the study of birds. 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, guild (ecology), guilds, insular biogeography, phylogeography, and bird conservation, 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 mo ...

Scientists From Stockholm
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ...

Argentine Ornithologists
Argentines, Argentinians or Argentineans are people from Argentina. This connection may be residential, legal, historical, or cultural. For most Argentines, several (or all) of these connections exist and are collectively the source of their being Argentine. Argentina is a multiethnic society, home to people of various ethnic, racial, religious, denomination, and national origins, with the majority of the population made up of Old World immigrants and their descendants. As a result, Argentines do not equate their nationality with ethnicity, but with citizenship and allegiance to Argentina. Aside from the indigenous population, nearly all Argentines or their ancestors immigrated within the past five centuries. Among countries in the world that have received the most immigrants in modern history, Argentina, with 6.6 million, ranks second to the United States (27 million), and ahead of other immigrant destinations such as Canada, Brazil and Australia. Ethnic groups Overvie ...
