Black-tailed Jackrabbit

Lepus californicus

Summary 5

The black-tailed jackrabbit (Lepus californicus), also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level to up to 10,000 feet (3,000 m). Reaching a length of about 2 feet (61 cm), and a weight from 3 to 6 pounds (1.4 to 2.7 kg), the black-tailed jackrabbit is the third largest North American hare, after the antelope jackrabbit and the white-tailed jackrabbit.

Description 6

Black-tailed Jackrabbits are tremendous leapers, able to jump more than 6 m horizontally. They live in some of the hottest and driest regions of the continent, can survive on poor-quality foods, and get most or all of the water they need from their food. Where they can, they eat green vegetation, but they can survive in parts of the Southwest where creosote-bush forms a large part of their diet. They cope with extreme heat by lowering their metabolism and resting in the shade during the day, which conserves water. They get rid of extra salt through their urine, and blood flows close to the skin in their enormous ears, a cooling mechanism. Although mostly nocturnal and solitary, large groups sometimes form near a good food supply. With their typically high reproductive output, Black-tails can be agricultural pests, and there were periods in the 1800s and 1900s when aggressive rabbit drives herded and destroyed 5,000-6,000 animal in a single day. In spite of this, they are quite common and widespread.
