Squirrels in California: where to look and what signs to watch for

1. Where are squirrels most common in California?

Squirrels are widespread across California but are most common in oak woodlands, mixed forests, and suburban neighborhoods. The California ground squirrel prefers open grassy areas, while the western gray squirrel sticks to oak and pine forests. The eastern fox squirrel thrives in urban parks and gardens. For reliable sightings, try parks like Griffith Park in Los Angeles or the oak woodlands of the Sierra Nevada foothills. Start with our California wildlife page for more regional tips.

2. What time of day are squirrels most active?

Squirrels are diurnal, meaning they are active during daylight hours. Peak activity occurs in the early morning (sunrise to 10 AM) and late afternoon (4 PM to sunset). They often take midday siestas in hot weather. Winter days may see shorter activity periods, while spring and fall offer longer feeding windows. If you want to watch their antics, plan your hike for these times.

3. What signs and tracks do squirrels leave?

Squirrel tracks show four toes on the front feet and five on the back, with a distinctive bounding pattern. Their droppings are small, oval pellets usually found near feeding sites. You might also notice gnawed pine cones, bark stripping, and leaf nests (dreys) high in trees. On the ground, look for dug-up patches where they bury acorns.

4. What do squirrels eat and where do they find food?

Squirrels primarily eat nuts, seeds, acorns, and tree buds. In California, they heavily rely on oak acorns, pine seeds, and walnuts. They also eat berries, fungi, and occasionally insects. You'll often see them under oaks and pines during mast years. Bird feeders are another reliable spot for urban squirrel watching.

5. How do seasons affect squirrel behavior in California?

Squirrels do not hibernate but are less active during cold, rainy spells. Spring and fall are the best seasons for spotting because they are busiest caching food and raising young. Mating seasons occur in late winter and mid-summer. During summer, they may be less active midday. In fall, watch for frantic gathering of acorns.
