Hoofed Mammals

Hoofed mammals, AKA “ungulates” aren’t just pigs and cattle. This category includes some of the world’s most spectacular mammals, from the tallest of all—giraffes—to some of the fastest—pronghorn antelope. WCS works from the plains of North America to the wetlands of Southern Sudan to save ancient wildlife migration corridors, study the environmental impacts of natural resource extraction, and develop sustainable land-use management plans to save Earth’s majestic hoofed herds.


The bison, North America’s largest mammal, once roamed the continent freely, helping sustain plain and prairie ecosystems through grazing. Today, most bison are being raised as domestic livestock.



Caribou, the most abundant land-dwelling animal in the Far North, are an adaptable species able to survive in harsh ecosystems. These deer are vulnerable to deforestation and climate change.



The tallest land animal with the longest tail, giraffes are found in many places in Africa. Still, some populations of giraffes may be facing extinction.



Wild relatives of the llama, guanacos are humpless camels that inhabit the arid and semi-arid habitats of South America, as well as the Andean forests of Tierra del Fuego.

White-Eared Kob


The yearly migrations of huge herds of white-eared kob in Southern Sudan rival that of wildebeest on the famed Serengeti Plains. The animals can cover nearly 1,000 miles a year.

Mongolian Gazelle

Mongolian Gazelle

These medium-sized antelope, characterized by a heart-shaped patch of white fur on their rump, are among the last great herds of migratory wildlife.



This solitary and strange-looking mammal that resembles a cross between a giraffe and a zebra lives only in the forests of the Democratic Republic of Congo. WCS helped safeguard the species by creating the Okapi Wildlife Reserve in 1992.



The pronghorn is the fastest land animal in North America. Traffic, recreation, and other human disturbances are driving pronghorns from their open grassland, sagebrush, and desert habitats.

Tibetan Schaller

Tibetan Antelope

Also known as chiru, these antelope once grazed in magnificent herds in the high mountain steppes of the Tibetan Plateau, but consumer demand for their luxurious wool has taken a heavy toll.
