Bison In this photo, an enormous bison is blocking traffic at Yellowstone National Park. This park has many animals, including bears, wolves, and elk. A bison can weigh as much as 900 kg. It is a very strong animal, so it can even push through snow.
Penguin These penguins are exploring their new outdoor pen. They live in a zoo in Switzerland. Some zoos keep their penguins in small, tight enclosures. However, penguins like to roam around.
