Abert's Squirrel (Sciurus aberti) lives in ponderosa pine forests across Southwestern North America. It feeds on pine seeds mostly. Its conservation status is Least Concern.
Fascinating facts about the Abert's Squirrel
- Abert's squirrels stretch up to 58 cm long, with a 25 cm tail, yet their most eye-catching feature is a 2-3 cm tuft that crowns each ear, a living flag that sets them apart from other tree squirrels. Those ear tassels not only give the species its nickname.
- A single Abert's squirrel may claim a summer home range 18 acres (7.3 ha) on average in central Arizona, with individual ranges spanning 10 to 24 acres (4.0 to 9.7 ha). In Colorado's Black Forest, the mean spring-summer range rises to 20 acres (8.1 ha), while some Arizona squirrels have been recorded using 10, 30 or even 60 acres (4.0, 12.2, 24.4 ha).
- When ponderosa pines boom, an Abert's squirrel can devour seeds from up to 75 cones in a single day, turning the forest into an all-you-can-eat buffet. In lean winter months the same squirrel gnaws through roughly 45 twigs each day, stripping bark to reach the nutrient-rich inner wood. Those feeding rates are supported by mature pines, trees 36-40 inches (91-102 cm) in diameter produce an average of 446 cones per crop.
- Abert's squirrel numbers can swing dramatically: in Colorado's spring of 1970 researchers counted 83 squirrels per square mile (30 /km²), but by spring 1971 that density fell to 33 per square mile (12 /km²). Yet the opposite trend appeared in the fall, when counts rose from 227 squirrels per square mile (82 /km²) in 1970 to a striking 317 per square mile (114 /km²) in 1971.
- Globally, the International Union for Conservation of Nature lists Abert's squirrel as "least concern". This contrast highlights how regional land-use practices can turn a common animal into a conservation priority.
