Bison Grunting Close-up Picture
Yes, I was in an SUV for this close-up. Bison are noisy with their deep grunts. This bull was tending a cow in Hayden Valley in Yellowstone National Park. At times, herds of these massive animals could number 800 (only a guess) or more and could be seen as far as the valley was visible.
