Somali Golden-winged Grosbeak
The Somali golden-winged grosbeak or Somali grosbeak (''Rhynchostruthus louisae'') is a finch endemic to Somaliland. It is included as a subspecies in ''R. socotranus'' by some authorities, but in recent times the three golden-winged grosbeak populations are usually considered distinct species. Description The males are grey-brown overall with a black bill that is smaller than in the other golden-winged grosbeaks. It has a dark face mask and large, bright yellow patches on the wings and tail. The females are similar to the males though somewhat duller, and the juveniles are rather streaky and the face mask is indistinct. Ecology and status The Somali golden-winged grosbeak is typically found between 1,060 and 2,800 metres ASL in forested wadis and areas of scrub, namely in relict East African Juniper (''Juniperus procera'') forests. The juniper fruit appear to form the bulk of its diet. This bird is the least-known of the golden-winged grosbeaks. Even before the start of the So ...

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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Somalia
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finches
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.''

Helm Identification Guides
The ''Helm Identification Guides'' are a series of books that identify groups of birds. The series include two types of guides, those that are: * Taxonomic, dealing with a particular family of birds on a worldwide scale—most early Helm Guides were this type, as well as many more-recent ones, although some later books deal with identification of such groups on a regional scale only (e.g., ''The Gulls Guide,'' which covers only species in Europe, Asia, and North America) * Geographic, including all bird species in an area (e.g., ''The Birds of the West Indies'') Early volumes were sometimes published under the Croom Helm or Christopher Helm imprints. In addition, a parallel set of guides, very similar in design, was published by Pica Press in the 1990s (marked ''Pica'' in the list below); Pica was later absorbed into A & C Black (now part of Bloomsbury Publishing Plc), and all guides are now marketed as a single series. Several of the books have won the British Birds ''Bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BirdLife International
BirdLife International is a global partnership of non-governmental organizations that strives to conserve birds and their habitats. BirdLife International's priorities include preventing extinction of bird species, identifying and safeguarding important sites for birds, maintaining and restoring key bird habitats, and empowering conservationists worldwide. It has a membership of more than 2.5 million people across 116 country partner organizations, including the Royal Society for the Protection of Birds, the Wild Bird Society of Japan, the National Audubon Society and American Bird Conservancy. BirdLife International has identified 13,000 Important Bird and Biodiversity Areas and is the official International Union for Conservation of Nature’s Red List authority for birds. As of 2015, BirdLife International has established that 1,375 bird species (13% of the total) are threatened with extinction ( critically endangered, endangered or vulnerable).

Near Threatened
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Somali Civil War
The Somali Civil War ( so, Dagaalkii Sokeeye ee Soomaaliya; ar, الحرب الأهلية الصومالية ) is an ongoing civil war that is taking place in Somalia. It grew out of resistance to the military junta which was led by Siad Barre during the 1980s. From 1988 to 1990, the Somali Armed Forces began engaging in combat against various armed rebel groups,Ken Menkhaus,Local Security Systems in Somali East Africa' in Andersen/Moller/Stepputat (eds.), Fragile States and Insecure People,' Palgrave, 2007, 73. including the Somali Salvation Democratic Front in the northeast, the Somali National Movement in the northwest, and the United Somali Congress in the south. The clan-based armed opposition groups overthrew the Barre government in 1991. Various armed factions began competing for influence in the power vacuum and turmoil that followed, particularly in the south. In 1990–92, customary law temporarily collapsed due to the fighting. This precipitated the arriv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
