Blue Wildebeest / Brindled Gnu (Connochaetes taurinus)
Adult blue wildebeest vary in color, from deep slate or bluish gray, through light gray to brown-gray.
The main coat is slightly lighter in color than the underparts. Dark brown vertical bands mark the neck and forequarters, and from a distance may seem to be wrinkles in the skin.
Young are born tawny brown, and begin to take on their adult coloration at 2 months of age.
Both sexes possess horns. Extending outward to the side and then curving up and slightly inward, the horns may grow 1 to 1.3 feet (30 to 40 cm) in females and 2.7 feet (83 cm) in males. They are slightly broadened at the base and have no ridges.
I. DESCRIPTION:
- Adult blue wildebeest vary in color, from deep slate or bluish gray, through light gray to brown-gray.
- The main coat is slightly lighter in color than the underparts. Dark brown vertical bands mark the neck and forequarters, and from a distance may seem to be wrinkles in the skin.
- Young are born tawny brown, and begin to take on their adult coloration at 2 months of age.
- Both sexes possess horns. Extending outward to the side and then curving up and slightly inward, the horns may grow 1 to 1.3 feet (30 to 40 cm) in females and 2.7 feet (83 cm) in males. They are slightly broadened at the base and have no ridges.
II. GEOGRAPHICAL RANGE AND HABITAT:
- Wildebeest inhabit open and brush-covered savanna in south and east Africa.
- Extremely territorial, adult males may occupy their territories for a few weeks or for the entire year.
- Territories vary in size from 2.5 to 4 acres; males mark the boundaries with dung heaps, preorbital gland secretions and pawing of the earth.
- When competing over territory, males grunt loudly, shove their horns and make other displays of aggression, although these behaviors rarely signal serious fights.
III. DIET:
IV. LIFE CYCLE/SOCIAL STRUCTURE:
- Only males with a territory may mate.
- Families are formed by females and young in groups of 10 to 1,000 animals. Young males (under 3 years of age) form small bachelor groups, while mature males are generally solitary.
V. SPECIAL NOTES/ADAPTATIONS:
- Births are seasonal, occurring two to three weeks before the summer rains. This flood of youngsters prevents predators from decimating the new population, as they might if births were spread out over a longer period of time.
- A young wildebeest can stand just 15 minutes after birth, and can follow its mother shortly thereafter.

 Thomson's gazelles are mainly grazers, feeding on grasses, herbs, and leaves of plants in the open plains. Their herds, which are composed of a dominant male, females, and their young, contain anywhere from five to fifty individuals.
The dominant male marks off his territory with urine and feces and regularly patrols its perimeter to keep his herd together. When he meets another male, they...

 The pronghorn is the fastest North American mammal, capable of sprinting up to forty miles (60 km) per hour and maintaining speeds of thirty miles (45 km) per hour.
It lives in small scattered groups in the summer, but in winter herds of up to a hundred may converge, foraging for grasses, weeds, shrubs, and forbs.
When a pronghorn is alerted to danger, the white hairs on its rump will stan...

 Herds of ten to forty gemsbock are not uncommon and groups of up to a hundred have been recorded.
These animals are frequently found in association with other species of gazelles and sometimes zebras, foraging for grasses and leaves.
Gemsbock can go many days without water, but in the more arid parts of their range, they sometimes dig a trough in a dried-out river bed to reach the water tabl...
