The brown-hooded kingfisher (Halcyon albiventris) is a species of bird in the subfamily Halcyoninae, the tree kingfishers. It has a brown head and blackish and turquoise wings. It is found in Sub-Saharan Africa, living in woodland, scrubland, forest edges, and also suburban areas.
A Regional Red List may be created by any country or organisation by following the clear, repeatable protocol. The process is as follows: All information relevant to a species conservation status is collected, including species distribution, population trend information, habitat, ecology and life history information, threats to the species and conservation measures currently in place.
The IUCN Red List of Ecosystems (RLE) is a global framework for monitoring and documenting the status of ecosystems. It was developed by the International Union for Conservation of Nature for biodiversity risk assessment. Its main objectives are to support conservation, resource use, and management decisions by evaluating all the world's ...
The IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
Endangered species by reason(s) they are (or were) threatened — the cause(s) for species being endangered in their native habitats.; This is primarily a sub-category for IUCN Red List species by the external threat(s) stated in IUCN reports for each listed species (hyperlinked under 'References' &/or 'External links' on most wikipedia articles when species are on IUCN Red List).
The ICUN compiled the “Red List”, evaluating the global conservation status of species based on the threat level. [15] The list separates species into threat levels ranging from least concern to extinct, aiding in directing efforts to mitigate species decline [16] This assessment evaluated factors contributing to species extinction like population size, trends, distributions, and threats.
These conservation status categories are used in Wikipedia articles. For threatened species and species believed to have become extinct after 1500, the categories are based on the IUCN (International Union for Conservation of Nature and Natural Resources) Red List 1994 or 2001 categories.
