Rudd's Lark
Rudd's lark (''Heteromirafra ruddi'') is a species of lark in the family Alaudidae. It is endemic to South Africa. Its natural habitat is high-altitude grassland. It is threatened by habitat loss. Taxonomy and systematics left, Bird in flight at Wakkerstroom, South Africa Formerly, some authorities have classified Rudd's lark as belonging to the genus ''Mirafra''. Previously, some authorities have also considered Archer's lark to be a subspecies of Rudd's lark (as ''Heteromirafra ruddi archeri''). Alternate names for Rudd's lark include long-clawed lark, Rudd's long-clawed lark and South African long-clawed lark. The name "long-clawed lark" has been used to describe both Rudd's lark and Archer's lark Archer's lark (''Heteromirafra archeri''), also known as the Liben lark, is a species of lark in the family Alaudidae. It is found in Somalia, Somaliland and Ethiopia. Its natural habitats are subtropical or tropical dry shrubland and subtrop .... References External links ...

Lark
Larks are passerine birds of the family Alaudidae. Larks have a cosmopolitan distribution with the largest number of species occurring in Africa. Only a single species, the horned lark, occurs in North America, and only Horsfield's bush lark occurs in Australia. Habitats vary widely, but many species live in dry regions. When the word "lark" is used without specification, it often refers to the Eurasian skylark ''(Alauda arvensis)''. Taxonomy and systematics The family Alaudidae was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors as a subfamily Alaudina of the finch family Fringillidae. Larks are a well-defined family, partly because of the shape of their . They have multiple scutes on the hind side of their tarsi, rather than the single plate found in most songbirds. They also lack a pessulus, the bony central structure in the syrinx of songbirds. They were long placed at or near the beginning of the songbirds or oscines (now often called Passeri), just afte ...

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] |
South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Mirafra
''Mirafra'' is a genus of lark in the family Alaudidae. Some ''Mirafra'' species are called "larks", while others are called "bush larks". They are found from Africa through South Asia to Australia. Taxonomy and systematics The phylogeny of larks (Alaudidae) was reviewed by Alström et al. (2013) who found that the following species form a well supported monophyletic group, which is the sister lineage to Heteromirafra. Extant species The genus contains twenty-four species: Former species Some authorities, either presently or formerly, recognize several additional species as belonging to the genus ''Mirafra'', including: * Short-clawed lark (as ''Mirafra chuana'') * Dusky lark (as ''Mirafra nigricans'') * Rufous-rumped lark (as ''Mirafra erythropygia'' or ''Mirafra nigricans erythropygia'') * Indian desert finch-lark (as ''Mirafra phoenicuroides'') * Rufous-tailed lark (as ''Mirafra phoenicura'') * Madagascan lark (as ''Mirafra hova'') * Sabota lark (as ''Mirafra sabota'') * ...

Archer's Lark
Archer's lark (''Heteromirafra archeri''), also known as the Liben lark, is a species of lark in the family Alaudidae. It is found in Somalia, Somaliland and Ethiopia. Its natural habitats are subtropical or tropical dry shrubland and subtropical or tropical dry lowland grassland. It is threatened by habitat loss. The bird's common name and binomial commemorate the British explorer and colonial official Sir Geoffrey Francis Archer. Taxonomy and systematics Formerly, the Liben lark has been considered by some authorities as belonging to the genus ''Mirafra''. The Sidamo lark was previously considered as a separate species (as ''H. sidamoensis'') and by some authorities as a subspecies of Liben lark (as ''H. a. sidamoensis''), but since 2014 has been considered conspecific with the Liben lark. Note that the alternate names "long-clawed lark" and "Sidamo lark" are also used as alternate names by Rudd's lark and Degodi lark respectively. Some authorities have also considered Archer's ...
