Arctic Tundra Birds

Most of the birds that live in the Arctic tundra go south during the winter. But some of them stay in the cold all year long! Ptarmigans are one of these.

Over 100 species of bird migrate to the tundra during the summer. Why, you ask? There are so many insects, that every bird gets a big meal!
