| Antelope Jackrabbits are nocturnal and crepuscular, and almost never vocalize. They are probably the fastest runners of their genus, with a top speed of 72 km per hour. They flash their white rumps somewhat as pronghorns do when they are running. Their ears are white on the outside, and longer than average. Typical of hares, and in contrast to rabbits, Antelope Jackrabbits give birth to well-developed young who are fully furred, with their eyes open, and able to hop.
