The gerenuk looks like nature’s rough draft of a giraffe — and it feeds like one too. This slender, long-necked antelope is the only one in Africa that regularly stands fully upright on its hind legs to browse, reaching leaves no other gazelle can touch. Restricted to the dry thornbush country of northern Kenya, it’s one of the most memorable and unusual animals on the Samburu circuit. Explore our Kenya safaris for a Samburu itinerary built around the region’s special species.
Key Highlights
- The only African antelope that regularly stands upright on its hind legs to feed
- Its name comes from the Somali word for “giraffe-necked”
- Can survive without ever drinking free-standing water, getting all its moisture from leaves
- Restricted to dry, semi-arid thornbush country in northern Kenya and the Horn of Africa
- Best afternoon viewing, when feeding activity peaks after the midday heat passes
- Shaba National Reserve often offers higher sighting odds than Samburu itself
The Giraffe Gazelle
The gerenuk (Litocranius walleri) takes its common name from a Somali word meaning “giraffe-necked” — an apt description for an antelope whose neck makes up a much larger share of its body than any other gazelle. That long neck, combined with a slim frame and unusually delicate legs, gives the gerenuk an almost otherworldly silhouette compared to the more familiar Thomson’s or Grant’s gazelle grazing nearby.
It’s also one of the most habitat-restricted antelopes in East Africa, found only in dry, semi-arid Acacia-Commiphora thornbush country across northern Kenya, southern Ethiopia, Somalia, and a narrow coastal strip down toward northern Tanzania. Unlike most gazelles, it avoids open grassland entirely, sticking to dense, thorny scrub that better matches its specialised browsing habits.
Standing Tall to Feed
The gerenuk’s signature behaviour, and the thing that makes it such a memorable sighting, is feeding while standing fully upright on its hind legs, often bracing its front legs against a branch for balance while it stretches its neck to reach leaves well above where any other gazelle could feed. No other African antelope does this routinely, and it’s not a simple party trick — the gerenuk’s whole body is built for it. Its legs are unusually long and lightweight relative to its body, its hips are proportionally wider to support the balance needed for standing upright, and its lower back has extra flexibility that lets the upper body tilt vertically while the hind legs stay planted.
This bipedal feeding style lets the gerenuk exploit a browsing niche that nothing else in its ecosystem really uses — too high for other gazelles and antelope to reach on four legs, but well below the level a giraffe would bother with. It’s most active in the afternoon, once the worst of the midday heat has passed, making late-day game drives the best time to catch this behaviour in action.
An Antelope That Doesn’t Need to Drink
Perhaps even more impressive than its feeding posture is the gerenuk’s ability to survive without ever drinking standing water. It gets all the moisture it needs directly from the leaves it eats, thanks to remarkably efficient kidneys that concentrate urine far more than most other African antelope species, minimising water loss. This water independence lets gerenuk spread out deep into dry thornbush country, far from rivers and waterholes, at exactly the time of year when species like impala and Thomson’s gazelle are forced to crowd around the nearest permanent water.
Where to See a Gerenuk
The Samburu-Buffalo Springs-Shaba reserve complex in northern Kenya is really the only place on the standard safari circuit where gerenuk are reliably found, making it essential for anyone hoping to add this species to their list. Because gerenuk favour dense scrub away from the river rather than open riverside grassland, spotting one usually means venturing into the reserve’s interior rather than sticking to the water’s edge.
Shaba National Reserve, with its especially dense Commiphora shrubland, tends to offer better odds than the more open sections of Samburu itself. Look for active bipedal feeders around dense acacia stands in the afternoon — once you find one, it’s often willing to stay in place browsing for several minutes, giving plenty of time for a good look and a photograph.
Frequently Asked Questions
Why is the gerenuk called the “giraffe gazelle”?
Its name comes from the Somali word for “giraffe-necked,” a reference to its unusually long, slender neck relative to other gazelle species.
Does the gerenuk really stand on two legs to feed?
Yes. It’s the only African antelope that routinely stands fully upright on its hind legs, often bracing against a branch, to reach leaves higher than other gazelles can access.
Where is the best place to see a gerenuk?
The Samburu-Buffalo Springs-Shaba reserve complex in northern Kenya is the main place to find gerenuk, with Shaba’s dense scrub often offering better odds than Samburu itself.
Does a gerenuk need to drink water?
No. Gerenuk can survive entirely on the moisture in the leaves they eat, allowing them to live far from permanent water sources.
