Greater Rhea

The greater rhea is a big, flightless bird from South America. It can grow up to 5 feet tall and weigh between 40-50 pounds. Rheas eat plants like leaves, roots, and seeds, but they also snack on insects. While the female lays up to 20 eggs in a nest on the ground, the male keeps them warm and raises the chicks. You can tell males apart because they have a ring of black feathers around their neck, while females are mostly gray and white.

Conservation Status: Near Threatened

Roosevelt Elk

Named after President Theodore Roosevelt, these are the largest elk in North America. Males can weigh over 1,000 pounds, and their antlers can grow up to 4 feet long.

Conservation Status: Least Concern

Fallow Deer

Fallow deer are easy to spot because of their spotted fur and unique shovel-shaped antlers that look like hands. Only males grow antlers, and they fall off and regrow every year! These deer grow to about 4 feet tall, and males can weigh over 200 pounds. Like other deer, they eat plants, including grass, leaves, and tree bark.

Conservation Status: Least Concern

Llama

Llamas are relatives of camels and have thick wool coats that help keep them warm in the mountains. They can grow up to 6 feet tall and weigh over 400 pounds.

Conservation Status: Domesticated

American Bison

The American Bison is the largest land animal in North America, growing up to 6.5 feet tall and weighing over 2,400 pounds. Even though they are huge, they can run up to 35 miles per hour. Bison fur is dark brown, but their babies (called calves) are burnt orange to help them blend into their grassy homes. Long ago, millions of bison roamed the U.S., but hunting nearly wiped them out. Today, only about 30,000 live in the wild.

Conservation Status: Near Threatened

African Elephant

African elephants are the largest land animals in the world! They can grow over 13 feet tall and weigh up to 14,000 pounds—that’s as heavy as two cars! They are bigger than Asian elephants and have large ears that look like the shape of Africa. Both males and females grow tusks, which they use for digging, stripping bark from trees, and protecting themselves.Elephants can live 60-80 years. They also have the longest gestation period of any mammal, with mothers carrying their babies for 22 months before giving birth.

Conservation Status: Endangered, due to poaching for their ivory tusks and habitat destruction

White Rhinoceros

White rhinos are the second-largest land mammals, right after elephants. They can grow up to 6 feet tall, 15 feet long, and weigh over 5,000 pounds—that’s as much as a small car. Even though they are called white rhinos, their skin is actually gray. Their name comes from a Dutch word, "wijde," meaning "wide," which describes their broad, flat mouths—perfect for grazing on grass. Unlike some other rhino species, white rhinos have two horns made of keratin (the same material as human fingernails).

Conservation Status: Near Threatened, due to poaching for their horns

Grant's Zebra

Grant’s zebras are known for their black-and-white stripes, but did you know no two zebras have the same pattern? Their stripes help them camouflage or blend in with each other, making it harder for predators like lions to pick one out from the herd. These zebras grow up to 4 feet tall at the shoulder and weigh between 500-700 pounds. Although they are thought of as horses, they are more closely related to a donkey. They spend most of their time grazing on grass and traveling in groups called herds.

Conservation Status: Least Concern, numbers are going down because of habitat loss and hunting

Asian Water Buffalo

Asian water buffaloes are strong, heavy animals that love water. They are often seen cooling off in muddy swamps and rivers.

Conservation Status: Least Concern

Ellipsis Waterbuck

Ellipsen waterbucks love staying near water to keep cool and escape predators. They have a white ring on their rump that looks like a target—this helps them follow each other in the wild. These antelopes are strong swimmers and mainly eat grass. Their numbers are stable, but they are sometimes hunted by predators and humans.

Conservation Status: Least Concern

Scimitar-Horned Oryx

This oryx has long, curved horns that look like scimitars (a type of sword)! It was once found all over North Africa, but due to hunting and habitat loss, it disappeared from the wild. Thanks to conservation efforts, scimitar-horned oryx are being reintroduced into protected areas, giving them a second chance in the wild!

Conservation Status: Extinct in the Wild

Red Ankole Cattle

Ankole cattle are famous for their huge, curved horns, which can grow over 8 feet long. These cattle are raised by people for milk, meat, and their strong ability to survive in hot climates.
