Harris' Antelope Squirrel

About the Harris' Antelope Squirrel

Harris's antelope squirrel (Ammospermophilus harrisii) 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.

The species is named after Edward Harris. Examples of 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 4–5 ounces (110–140 g), and measure 8.5–10 inches (22–25 cm) minus their tail, which measures 3–4 inches (7.6–10.2 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. A. harrisii also participates in a heat reduction method where individuals move into shaded positions... Wikipedia →
