The Arabian Ostrich Struthio camelus syriacus was thought to have become extinct sometime in the late 1960s. Here we review radiometric dates for ostrich eggshell, and present 14 new calibrated accelerator mass spectrometry or C14 data, indicating that the ostrich survived in the north of Saudi Arabia until at least in the1960s. Their C14 age, derived from 14 samples, date from 384 ±22 to 50100 ± 800 years from present. This study provides data of the distribution of the Arabian Ostrich through C14, and how humans extirpated the Arabian ostrich. It also assesses possible corridors for the northern and southern populations in Saudi Arabia. Genetically closely related to Arabian Ostrich is the Red-necked Ostrich (Struthio camelus camelus), which has been re-introduced in two reserves, one in Mahazat as-Sayd Protected Area in late 1990s in central Saudi Arabia; and in April 2017 a group of 10 S.c. camelus were released in ‘Uruq Bani Ma’arid Protected Area in the Empty Quarter in the southern part of the country, while it is planned to be re-introduced in al Khunfa, Harrat al Harrah reserves in the north, and As Shaiba (biodiversity area) in southeast, where the Arabian Ostrich was recorded historically. |
