Squirrels are a familiar presence in many environments, from bustling city parks to quiet suburban backyards. While their movements might appear random, these agile rodents generally follow a structured daily routine, influenced by various environmental factors.
When Squirrels Are Most Active
Squirrels are primarily diurnal, meaning they are active during daylight hours and rest at night. Their daily activity typically follows a bimodal pattern with two distinct peaks. The first peak occurs in the early morning, shortly after sunrise, when temperatures are cooler. During this time, squirrels commonly forage for food and bury it for later consumption.
Activity often decreases during the late morning and early afternoon, a period referred to as a “midday lull.” Squirrels then experience a second surge of activity in the late afternoon, lasting until dusk. This period is dedicated to gathering and storing food, and engaging in social interactions.
What Influences Their Daily Schedule
Several environmental and seasonal factors influence squirrel activity. Temperature plays a role, as squirrels tend to avoid extreme heat or cold, leading to reduced activity during the hottest summer days or coldest winter periods. Light levels, tied to sunrise and sunset, also dictate their emergence and retreat, as they typically emerge at dawn and return to their nests before dusk.
Food availability is another significant driver; increased activity is observed during periods of abundant food. Seasonal changes cause variations in active hours, with longer summer days allowing for extended foraging, while winter sees reduced activity, often limited to colder mornings. The presence of predators can also influence their timing, as squirrels may adjust activity to avoid times when predators are most active.
Where Squirrels Go When Not Active
When squirrels are not active, particularly during the midday lull or at night, they retreat to secure shelters for rest and safety. Tree squirrels commonly use nests known as dreys, constructed from twigs, dry leaves, and grass, often located in the forks of tall trees. These structures serve as protection from predators and adverse weather.
Squirrels also utilize natural tree cavities or hollows within tree trunks or branches, referred to as dens. These provide enhanced protection and insulation, making them preferred choices during colder months. While squirrels are occasionally observed venturing out briefly at night, their nocturnal activity is generally limited, as they are primarily daytime animals that rest at night.
