Grevy's zebras (or imperial zebras) are the largest living equid and the most endangered of the three zebra species. They can only be found in northern Kenya and a few isolated pockets of land in Ethiopia. Most safari-goers are familiar with plains zebras (the most populous species found throughout East and Southern Africa), and some have seen the mountain zebras of South Africa and Namibia.

Grevy's zebras can be distinguished by their large heads, rounded ears, and narrow black-and-white body stripes. The stripes extend to the flank, leaving a white belly. They are active day and night and occur in small groups. However, they are less social than plains zebras and show less social behavior, such as grooming.

There are only two species of ostrich: the common ostrich and the Somali ostrich. They look very similar, but the male common ostrich has a pink neck and pink legs, while the male Somali ostrich has a blueish neck and thighs.

The Somali Ostrich is an elusive bird species and possibly the biggest bird on earth. It differs from the common ostrich and was declared a distinct species in 2014. Somali ostriches are large, flightless birds identified by their grey-blue necks and thighs. In the mating season, the blue on male ostriches becomes bright blue.

Though Somali ostriches are a distinct species of ostrich, they can be found in the Horn of Africa in Somalia, Ethiopia, and Northern Kenya's Samburu National Reserve.

Gerenuk, also known as giraffe gazelle, is a notably tall, slender bird with an abnormally long neck adapted to feeding on acacia trees while standing on its hind legs with a wedge-like head and large, round eyes. It is characterized by its long, slender neck and limbs. They have two types of coloration that are visible on their smooth coat: the reddish brown back, or "saddle," and the lighter flanks, fawn to buff. The horns, present only in males, are lyre-shaped. Curved backward, then slightly forward. Their underbelly and insides of the legs are creams in color. The eyes and the mouth are surrounded by white fur. Females have a dark patch on the crown.

The gerenuk is a diurnal animal. It is active mainly during the day, though it typically stands or rests in the shade during the afternoon. Foraging and feeding are the major activities throughout the day. Females appear to spend more time feeding. The gerenuk may expose itself to rain, probably to cool its body. The social structure consists of small herds of two to six members. Herds typically comprise members of a single sex, though female herds additionally have juveniles. Some males lead a solitary life.
