The African savannah is home to an incredible array of wildlife, including one of the most graceful and iconic animals of the region - the Thomson's gazelle. With their distinctive markings and swift running, these antelopes are a common sight in many national parks and game reserves. But there is much more to learn about this fascinating creature, from its scientific classification to its behavior and lifestyle. In this article, we will explore the world of Thomson's gazelles, including their evolution, physical description, social structure, habitat, predators and threats, and much more.
Scientific Name and Classification:
Thomson's gazelle, also known as "tommies," has the scientific name Eudorcas thomsonii. They belong to the Bovidae family, which includes other antelopes, goats, and sheep. Within the Bovidae family, Thomson's gazelle is classified under the subfamily Antilopinae, which includes other African and Asian antelopes.
Thomson's gazelle is a small-sized antelope that inhabits the African savannah, specifically in countries such as Kenya, Tanzania, Uganda, and Somalia.
Thomson's gazelle is named after the Scottish explorer Joseph Thomson, who first discovered the animal in 1884. Since then, these antelopes have become one of the most recognized and studied species in Africa.
Evolution and Origins:
The history of Thomson's gazelle dates back to the Miocene epoch, around 8 million years ago. It is believed that the first antelopes evolved in Eurasia and then spread to Africa. Thomson's gazelle, along with other antelopes, evolved to adapt to the grasslands and savannahs of the continent.
Thomson's gazelle has a compact and streamlined body, which makes it one of the fastest running antelopes in Africa. They have a reddish-brown coat with a distinctive white patch on the rump and black stripes on the side. The males have curved horns that can grow up to 30 centimeters long, while the females are hornless.
Thomson's gazelle is a social animal that lives in herds of up to hundreds of individuals. The herds consist of females, their offspring, and a few males. The males compete for dominance and access to females during the breeding season.
Anatomy and Appearance:
Thomson's gazelle has several adaptations that help it survive in the harsh African savannah. Their long legs and lightweight body make them excellent runners, capable of reaching speeds of up to 80 km/h. Their eyes are located on the side of the head, which gives them a wide field of vision and allows them to detect predators easily.
Distribution and Habitat:
Thomson's gazelle is found in several African countries, including Kenya, Tanzania, Uganda, and Somalia. They inhabit the grasslands and savannahs of the continent, where they feed on grass and other vegetation.
Population – How Many Are Left?
Thomson's gazelle is classified as a species of "Least Concern" by the International Union for Conservation of Nature (IUCN). However, their populations have been declining due to habitat loss and hunting. The exact number of Thomson's gazelles in the wild is unknown, but they are estimated to be in the hundreds of thousands.
Thomson's gazelle is a small-sized antelope, with males reaching up to 70 cm at the shoulder and females up to 60 cm.
The average weight of a Thomson's gazelle is around 25-35 kg.
Behavior and Lifestyle:
Thomson's gazelle is a diurnal animal, meaning they are active during the day and rest at night. They feed on grass and other vegetation and can go for long periods without water, obtaining most of their moisture from their diet. During the dry season, they will migrate to areas with more abundant water sources.
Breeding in Thomson's gazelles occurs throughout the year, although there is a peak during the rainy season. Males will compete for dominance and access to females during this time. After a gestation period of around 6 months, females will give birth to a single calf. The calf is able to stand and walk within a few minutes of being born and will begin to nurse shortly after.
Thomson's gazelle calves are born with a brown coat and will develop the distinctive reddish-brown coat with white rump patch and black stripes as they mature. They are able to stand and run within minutes of being born and will stay close to their mothers for protection.
The lifespan of a Thomson's gazelle is around 10-15 years in the wild.
Diet and Prey:
Thomson's gazelle is a herbivore, feeding on grass and other vegetation. They are preyed upon by a variety of predators, including lions, cheetahs, leopards, and hyenas.
Predators and Threats:
Thomson's gazelle faces several threats in the wild, including habitat loss due to human activities such as agriculture and urbanization. They are also hunted for their meat and hides, and the horns are sometimes collected as trophies. Predation by large carnivores is also a significant threat, particularly to young and vulnerable individuals.
Relationship with Humans:
Thomson's gazelle has a mixed relationship with humans. While they are sometimes hunted for meat and hides, they are also an important part of the tourism industry in Africa. Visitors from around the world come to see these graceful antelopes in their natural habitat.
- Thomson's gazelle is one of the fastest running antelopes in Africa, capable of reaching speeds of up to 80 km/h.
- They can survive for long periods without water, obtaining most of their moisture from their diet.
- The white patch on their rump is believed to act as a signal to other members of the herd, helping to keep them together.
- Males will sometimes engage in "pronking," a behavior where they jump high into the air while running. This is believed to be a display of dominance and strength.
- Thomson's gazelle has a unique alarm call, a high-pitched whistle, which alerts other members of the herd to the presence of predators.
- They have excellent eyesight, with the ability to detect predators from long distances.
- The name "tommies" comes from their scientific name, Eudorcas thomsonii, which honors the Scottish explorer Joseph Thomson.
