Goitered Gazelle

The goitered gazelle, also called the black-tailed gazelle, is a lightly built antelope of dry country. Its English name refers to the conspicuous enlargement of an adult male's neck and throat during the breeding season. The species account consulted does not provide enough dependable measurement or coat detail to support a fuller field identification, so size and colour figures are omitted here. Its inclusion in Mongolia is explicit in the species-wide range, which extends across much of Central and western Asia. (Wikipedia, general species account)

The species inhabits sand and gravel plains as well as limestone plateaus. It is capable of fast running without the pronounced bounding gait associated with some other gazelles. Mating is polygynous and generally takes place in early winter. Populations over much of the range move seasonally, with herds covering greater daily distances in winter than in summer. These are species-wide ecological characteristics; the consulted account did not identify a particular Mongolian reserve or describe a Mongolia-specific seasonal route.
