"Harris's Antelope Squirrel," Wikipedia, the free encyclopedia. Harris's antelope squirrel is a species of rodent in the family Sciuridae. It is found in Arizona and New Mexico in the United States, and in Sonora in Mexico. They are adapted to hot weather conditions including a technique called "heat dumping". They have a wide-ranging diet, including both vegetation, insects, small rodents and carrion. A. harrisii have distinctive markings on their grey fur, with brown highlights on the sides and legs and a white strip down the side of the torso and encircling their eyes. Their fur grows longer in the winter than it does in the summer. Adults weigh around 45 ounces (110140 g), and measure 8.510 inches (2225 cm) minus their tail, which measures 34 inches (7.610.2 cm). They can be mistaken for chipmunks. A. harrisii has a high body temperature of 97-107 degrees Fahrenheit (36.7 - 41.6 C) in order to protect itself from the heat of the Sonoran Desert, A. harrisii carries their tails over their bodies in order to provide shade.
