Grazing Goitered Gazelles
The goitered or black-tailed (Gazella subgutturosa) is a gazelle found in northern Azerbaijan, eastern Georgia, part of Iran, parts of Iraq and southwestern Pakistan, southeastern Turkey, Afghanistan and the Gobi Desert. The specific name, meaning "full below the throat", refers to the male having an enlargement of the neck and throat during the mating season.
The goitered gazelle inhabits sands and gravel plains and limestoneplateau. It runs at high speed, without the leaping, bounding gait seen in other gazelle species. Throughout much of their range, goitered gazelles migrate seasonally. Herds cover 10–30 km per day in the winter, with these distances being reduced to about 1–3 km in summer.
Large herds were also present in the Near East. Some 6,000 years ago, they were captured and killed with the help of desert kites. Rock art found in Jordan suggests ritual slaughter.
Until recently, goitered gazelles were considered to represent a single, albeit polymorphic, species. However, recent genetic studies show one of the subspecies, G. s. marica, is paraphyletic in respect to the other populations of goitered gazelles, although gene introgression is observed in the contact zone between the two species.
