Habitat
American red squirrels primarily inhabit coniferous forests across North America, from Alaska to the Appalachian Mountains. They prefer mature stands of pine, spruce, and fir trees for food and nesting sites. They are adaptable to mixed woodlands but avoid open areas and dense urban environments.
Diet
Their diet consists mainly of seeds from conifer cones, which they harvest and store in large middens. They also eat fungi, berries, buds, and occasionally insects or bird eggs. Feeding activity peaks in the early morning and late afternoon, with squirrels often seen caching food for winter.
Behavior
American red squirrels are solitary and highly territorial, defending their areas with loud chattering calls and aggressive chases. They are diurnal, most active during the day, and spend time building nests in tree cavities or branches. Notable behaviors include hoarding food in middens and emitting alarm calls to alert others of predators.
Conservation Status
The IUCN classifies the American red squirrel as Least Concern, with a stable population trend across its range. Major threats include habitat fragmentation from logging and competition from invasive species, but it remains widespread and abundant.
