Chilean Mockingbird
The Chilean mockingbird (''Mimus thenca''), locally known as ''tenca'', is a species of bird in the family Mimidae. It primarily inhabits Chile's northern half, though there are sightings in Argentina. Taxonomy and systematics The Chilean mockingbird is monotypic. Description The Chilean mockingbird is long and weighs . The male is somewhat larger than the female. Adults have a wide whitish supercilium . Their crown, neck, and back are brownish gray with darker streaks and their rump browner. The wings and tail are blackish. The wings show two narrow bars when folded. The outermost tail feathers have white edges and most of the others have white tips. The throat is whitish, the chest brownish gray, the belly dirty white, and the flanks buffy with blackish streaks. The juvenile is similar but more buffy below with more streaks.Cody, M. L. (2020). Chilean Mockingbird (''Mimus thenca''), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D.

Tropical Mockingbird
The tropical mockingbird (''Mimus gilvus'') is a resident breeding bird from southern Mexico to northern and eastern South America and in the Lesser Antilles and other Caribbean islands. Taxonomy and systematics The tropical mockingbird has sometimes been considered conspecific with its closest living relative, the northern mockingbird (''Milvus polyglottos''), and forms a superspecies with it. The critically endangered Socorro mockingbird (''M. graysoni'') is also much closer to these two than previously believed. The tropical mockingbird has these ten subspecies: *''M. g. gracilis'' Cabinis (1851) *''M. g. leucophaeus'' Ridgway (1888) *''M. g. antillarum'' Hellmayr & Seilern (1915) *''M. g. tobagensis'' Dalmas (1900) *''M. g. rostratus'' Cabinis (1851) *''M. g. melanopterus'' Lawrence (1849) *''M. g. gilvus'' Vieillot (1808) *''M. g. tolimensis'' Ridgway (1904) *''M. g. antelius'' Oberholser (1919) *''M. g. magnirostris'' Cory (1887) ''M. g. antelius'' and ''M. g. ...

List Of Commonly Used Taxonomic Affixes
This is a list of common affixes used when scientifically naming species, particularly extinct species for whom only their scientific names are used, along with their derivations. *a-, an-: ''Pronunciation'': /ə/, /a/, /ən/, /an/. ''Origin'': grc, ἀ-, ἀν- (''a, an-''). ''Meaning'': a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less".

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which in his view is intentional, whereas natural selection is not. Genetic diversity, Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the Cell (biology), cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes, which are passed on from parent to offspring during reproduction. Variation tends to exist within any given population as a result of genetic mutation and recombination. Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or more rare within a population. The evolutionary pressures that determine whether a characteristic is common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms, and molecules. The theory of evolution by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Galápagos Mockingbird
The Galápagos mockingbird (''Mimus parvulus'') is a species of bird in the family Mimidae. It is endemic to the Galápagos Islands, Ecuador. Systematics The Galápagos mockingbird is one of four mockingbird species endemic to the Galápagos Islands. These four are all closely related, and DNA evidence shows they likely all descended from an ancestor species which reached the islands in a single colonization event. When John Gould first described the species in 1837, based on specimens brought back from the islands by Charles Darwin, he named it ''Orpheus parvulus''. However, because of the rules of binomial nomenclature, ''Orpheus'' was declared a junior synonym, and in 1841, George Robert Gray moved all of the ''Orpheus'' mockingbirds to the older genus ''Mimus''. In 1890, Robert Ridgway created the genus ''Nesomimus'' for the mockingbirds found on the Galápagos Islands, and most taxonomists adopted the change. Recent DNA studies, however, show that the ''Nesomimus'' mockingbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
