Capra nubiana
Résumé
The Nubian ibex (Capra nubiana) is a desert-dwelling goat species (Genus Capra) found in mountainous areas of northern and northeast Africa, and the Middle East. It was historically considered to be a subspecies of the Alpine ibex (C. ibex), but is now considered a distinct species. The wild population is estimated at 4,500 mature individuals, and it is classified as vulnerable.
Nubian ibex are the smallest ibex species on Earth, following Bergmann's rule. They stand around tall at the shoulder. They are sexually dimorphic: males are significantly larger than females, with males averaging and females .
They are a light tan color, with a white underbelly; males also have a dark brown mane down their backs. Their legs have a black and white pattern. They have a lighter rump with a dark brown tail. Males begin growing a beard at age 2 or 3, which continues to grow longer and darker as they age. During the autumn breeding season, mature males grow a "rutting fur" on their breast and sides which is very dark brown. It appears in October in 3–4-year-old males, but it may appear as early as July or August in older males age 6 and up. However, not all males develop rutting fur, even at a mature age.
Nubian ibexes have long, thin horns that extend up and then backwards and down. In males, these reach around in length, while in females they are much smaller, reaching around . Male horns are thicker than female horns, and grow large bulges which prevent the horns from sliding while the males are locked in combat. Male horn growth plateaus around age 7–8, where as female horn growth plateaus around age 4–6. There is a significant relationship between the individual's age and the number of horn ridges.
Historically, Nubian ibex were distributed across the Middle East and Northeastern Africa.
Its range today is within Egypt, Jordan, Oman, Israel, Palestine, Saudi Arabia, and Sudan. It was extirpated in Lebanon, though a captive breeding and reintroduction process is underway. It has also been extirpated in Syria.
