They may remind you of Bugs Bunny, but they're more like the road runner. These big rabbits are built for speed: they can easily run 35 miles per hour with spurts of speed that exceed 45 miles per hour. In fact, jackrabbits will run faster than your car can travel on a bumpy back-country road. And if you think their running is impressive, just wait until you see them jump: they can leap from 12 to 20 feet at a time. Obviously, they need that athleticism to escape predators on the open prairie. In the summer, jackrabbits are a sandy color; in the winter they change to pure white, which helps them blend in with their surroundings. They eat mainly grasses; when they can get into a hay field, they love clover and alfalfa. A single female jackrabbit will have two to four litters per year with an average of four to six bunnies per litter. That's anywhere between eight and 24 offspring every year. Obviously, the rabbit's legendary prowess at reproduction is well-deserved.
