Lesser kudu, Tragelaphus imberbis, of eastern Africa
Greater kudu, Tragelaphus strepsiceros, of eastern and southern Africa
The two species of the Kudus look quite similar, though Greaters are larger than the lesser kudu.
A large adult male Greater Kudu stands over 5 ft. tall, and a large male Lesser Kudu stand about 4 ft. tall.
Both species have long horns, which point upward and slightly back, and curl in a corkscrew shape.
A pregnant female will leave the herd to give birth to a single offspring.
She will leave the newborn lying hidden for 4–5 weeks while coming back only to nurse it, which is the longest nursing period of any antelope species.
Then the calf will start accompanying its mother for short periods.
At 3 or 4 months, the calf will be with its mother constantly, and at about six months they will rejoin the group.
