Arabian bustard
The Arabian bustard (''Ardeotis arabs'') is a species of bird in the bustard family. It is part of the largest-bodied genus (''Ardeotis'') and, though little known, appears to be a fairly typical species in that group. As in all bustards, the male Arabian bustard is much larger than the female. Males have been found to weigh , while females weigh . The record-sized male Arabian bustard weighed . These birds stand from tall in females to tall in males.〔Dunning, John B., Jr. (ed.) ''CRC Handbook of Avian Body Masses''. CRC Press (1992), ISBN 978-0-8493-4258-5.〕 They are fairly similar in overall appearance to the kori bustard, with a brown body, gray neck and white underside, but are noticeably smaller, with a more elegant, slender build. They are also differ in having white checkered covert pattern at the end of the folded wing, as opposed to various black-and-white patterns as seen in other large African bustards.〔Stevenson, Terry and Fanshawe, John (2001). ''Field Guide to the Birds of East Africa: Kenya, Tanzania, Uganda, Rwanda, Burundi''. Elsevier Science, ISBN 978-0856610790〕 These birds mainly live off arthropods and larvae.〔(Arabian Bustard ).

It is found in Algeria, Burkina Faso, Cameroon, Chad, Ivory Coast, Djibouti, Eritrea, Ethiopia, Gambia, Ghana, Guinea-Bissau, Iraq, Kenya, Mali, Mauritania, Morocco, Niger, Nigeria, Saudi Arabia, Senegal, Somalia, Sudan, and Yemen. Due to its wide range, it was not considered vulnerable by IUCN, although there is believed to have been a strong decrease in the population. In 2012 the species was uplisted to Near Threatened.〔(【引用サイトリンク】url=http://www.birdlife.org/action/science/species/global_species_programme/whats_new.html )〕 The primary cause of the decrease appears to be heavy hunting pressure, with habitat degradation and destruction also playing a major role.〔
