Black-tailed Jackrabbit and Antelope Jackrabbit

Lepus californicus and Lepus alleni

The black-tailed jackrabbit (left) and antelope jackrabbit (right) are often seen idling or running together in Arizona and Mexico, where their ranges overlap. But make no mistake—these are two different species. Even small traits count. Both hares have long ears and legs, but antelope jackrabbits’ ears are even more enormous. Black-tailed jackrabbits are distinguished by black tails and ear-tips. In a race, the antelope jackrabbit would win, reaching speeds of 44 miles (72 kilometers) per hour.
