A close-up of a male Thomson's gazelle: males have horns that are thicker and longer than those of the female. Thomson's gazelle is a relatively small gazelle; it stands 60–70 cm (24–28 in) at the shoulder. Males weigh 20–35 kg (44–77 lb), while the slightly lighter females weigh 15–25 kg (33–55 lb).
The social structure of the springbok is similar to that of Thomson's gazelle. Mixed-sex herds or harems have a roughly 3:1 sex ratio; bachelor individuals are also observed. [14] In the mating season, males generally form herds and wander in search of mates. Females live with their offspring in herds, that very rarely include dominant males.
The impala is a medium-sized, slender-bodied antelope, comparable to the kob, puku and Grant's gazelle in size and build. [17] The head-and-body length is around 130 centimetres (51 in). [18] Males reach approximately 75–92 cm (30–36 in) at the shoulder, while females are 70–85 cm (28–33 in) tall.
Bovids range in size from the 38 cm (15 in) long royal antelope to the 3.3 m (11 ft) long gaur, which can reach 1,500 kg (3,300 lb) in weight. [1] Over a billion each of domesticated sheep , cattle , and goats , and over 200 million domesticated water buffalo , 14 million domestic yak , and 300,000 domesticated gayal are used in farming worldwide.
The Grant's gazelle looks similar to a Thomson's gazelle, except it is much larger and has lyre-shaped horns which are stout at the base, clearly ringed, and measuring 45–81 cm (18–32 in) long. A useful field mark is the white on the rump that extends over the top of the tail in Grant's but not Thomson's gazelles.
The red-fronted gazelle gives birth to one fawn after a gestation period of 184–189 days. The fawn is likely to wean at around three months. Based on the closely related Thomson's gazelle, females may breed as early as nine months, while males may not mature until 18 months. [9] The lifespan is up to 14.5 years in captivity.
They have a territorial male as a leader in herds and sometimes group with other species, such as Grant's gazelle joining with Thomson's gazelle. [1] They can reach top speeds of 50 miles per hour (80 km/h) and have the ability to jump and turn sharply. They have adapted well to running in open environments. [2]
On the other hand, in their 2011 publication Ungulate Taxonomy, Grubb and Groves consider the gazelle as a full-fledged species in the genus Eudorcas. [5] Gentry in 1972 and Grubb in 2005 noted that the Mongalla gazelle is more similar to the red-fronted gazelle in skull and horn proportions than to the Thomson's gazelle. [6]
