This page is a forest in the mountains of North America. Move your pointer across the pine needles and your animal will lumber, lope, waddle or soar after you. Choose a different animal at the bottom, and tap the notes to open them.
Yellowstone right now checking the sky…
The pale tips to its brown hairs give it a frosted, grizzled look.
The hump on its shoulders is muscle, which powers its front legs for digging.
It spends five to seven months in a den without eating or drinking, living on its fat.
For all its bulk, a grizzly can run at 35 miles an hour.
Its sense of smell is thought to be many times better than a bloodhound's.
Roots, berries, moths, nuts and salmon: a grizzly eats whatever is in season.
Meet them all

Through the year
The green months are when each one is up and about. The bear spends the winter asleep in its den. The animal following you is shown in red.
Good to know
Canada's northern forest is one of the largest left on Earth, with more lakes than the rest of the world put together.
Needle-leaved trees keep their leaves all winter, and their shape lets heavy snow slide off.
Animals here sleep through the cold, grow a thicker coat, or leave for the south.
Yellowstone, in the United States, became the world's first national park in 1872.
Beavers change the forest more than any animal except people: their dams make ponds that many others live in.
Wolves were put back into Yellowstone in 1995, and the whole valley changed: fewer deer, more trees, more beavers.

A band of forest runs right across the top of North America, from Alaska to the Atlantic: pine, spruce and fir, lakes and rivers, and long, hard winters.
