Harris' antelope squirrel

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.<br><br>
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 and lie spread eagled against the ground. This is referred to as "heat dumping". They are active during the day, and do not sweat but otherwise reduce temperature by salivating. (information from Wikipedia)
