The gerenuk (Litocranius walleri), also known as the giraffe gazelle, is a long-necked, medium-sized antelope found in parts of East Africa. The sole member of the genus Litocranius, the gerenuk was first described by the naturalist Victor Brooke in 1879. It is characterised by its long, slender neck and limbs. The antelope is 80–105 centimetres (2 feet 7 inches – 3 feet 5 inches) tall, and weighs between 18 and 52 kilograms (40 and 115 pounds). Two types of colouration are clearly visible on the smooth coat: the reddish brown back or the "saddle", and the lighter flanks, fawn to buff. The horns, present only on males, are lyre-shaped. Curving backward then slightly forward, these measure 25–44 cm (10–17+1⁄2 in).
The gerenuk was first described by Victor Brooke in 1879 on the basis of three male specimens procured on "the mainland of Africa, north of the island of Zanzibar". Brooke used the scientific name Gazella walleri, on the request of Gerald Waller (who provided the specimens) to name it after his deceased brother. The type locality was later corrected by John Kirk, who originally obtained the specimens on the "coast near the River Juba in southern... Wikipedia →

Possible
About 20% of wildlife watchers report a Gerenuk sighting in Tsavo West National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 33 mammals we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Gerenuk in Tsavo West National Park on a given day, against under 5% in January–May and October, the lowest months. That is one of Tsavo West National Park's driest months, with about 10 mm of rain against 140 mm in November.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Gerenuk sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
5th of 6
Of the 6 parks where we can rate Gerenuk sightings, Tsavo West National Park ranks 5th at about 20%. The best odds are in Tsavo East National Park (Kenya, about 70%), Samburu National Reserve (Kenya, about 60%) and Meru National Park (Kenya, about 40%). All parks ranked.
Same family: Bovidae
The closest relatives of the Gerenuk that you can see in Tsavo West National Park (family Bovidae, Bovids) are East African Oryx (about 70%), African Buffalo (about 70%) and Lesser Kudu (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gerenuk is recorded against all the mammals logged in Tsavo West National Park (12 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
