Birds are an important part of alpine tundra communities. Long-tailed Jaegers are carnivorous relatives of gulls. They prey on chicks of other birds. Gray Jays are one of the few birds that can manage staying in Alaska throughout the winter. Gyrfalcons nest on vertical cliffs overlooking valleys.
Gyrfalcons are the largest falcons and one of the fastest birds on planet Earth.
The ptarmigan is a grouse-like bird. In the summer, the males are red-brown with white color underneath and females are spotted brown. But, in the winter, they are both all white with a black tail. Golden Eagles spend their summers in alpine areas. They are powerful hunters that eat ground squirrels, ptarmigan, marmots, and hares.
