Move over grizzlies and wolves: Yellowstone visitors hope to catch a glimpse of rare white buffalo

The recent appearance of a rare white bison calf has excited wildlife watchers in Yellowstone National Park. Many from far and wide are keeping a close watch for the elusive animal since Montana wildlife photographer Erin Braaten got several photos of the calf with its mother on June 4, soon after its birth. Few others saw the white bison calf and it has not been spotted since, leading to speculation it may have died. Even so, the creature's birth is auspicious for Native Americans, who say it fulfills a Lakota prophesy that portends better times. They are planning an upcoming ceremony to commemorate the event.
