Syrian ostrich : ウィキペディア英語版 | Arabian ostrich
The Arabian ostrich or Syrian ostrich (''Struthio camelus syriacus'') is an extinct subspecies of the ostrich which lived on the Arabian Peninsula and in the Near East until the mid-20th century. ==Distribution== Its range seems to have been continuous in prehistoric times, but with the drying-up of the Arabian Peninsula, it disappeared from the inhospitable areas of the Arabian Desert, such as the Rub'al-Khali. In historic times, the bird seems to have occurred in two discrete relict populations: a smaller one in the southeast of the Arabian Peninsula (8.8 feet tall) and a larger one in the area where today the borders of Saudi Arabia, Jordan, Iraq and Syria meet (10 feet tall). Towards the Sinai Peninsula, it probably intergraded with the North African subspecies ''camelus'' in earlier times. It looked exactly like that form; possibly, the females were of a slightly lighter coloration. The only certain way to distinguish ''camelus'' and ''syriacus'' was the smaller size of the latter, with only marginal overlap: the tarsus was 390–465 mm long in ''syriacus'' versus 450–530 mm in ''camelus''.
