Welcome back, little mountain bluebird. Although this bright fellow may be enduring the last of this year"s snow in Yellowstone National Park, his presence means winter will soon be ending. The bluebird is a symbol of happiness and a welcome sign of spring in many cultures. Soon other migratory birds will arrive in the Greater Yellowstone Ecosystem—an 18-million-acre tract that includes Grand Teton National Park and surrounding national forests. It"s the world"s largest intact ecosystem in the northern temperate zone. What exactly does that mean? Since wolves were reintroduced to Yellowstone 25 years ago, all the animal species that were first documented by European explorers can still be found here.
Hello, harbinger of spring
