Habitat
This species is found exclusively on Isla Espiritu Santo in the Gulf of California, inhabiting arid shrublands, rocky hillsides, and desert scrub. It prefers areas with sparse vegetation, cacti, and boulders that provide burrowing sites and protection from predators. The terrain is typically dry and hot, with minimal rainfall.
Diet
It primarily consumes seeds, nuts, and fruits from desert plants like mesquite and cacti, along with insects and green vegetation. Feeding behavior is diurnal, with the squirrel foraging actively in the morning and late afternoon, using its cheek pouches to store food for later consumption.
Behavior
These squirrels are diurnal and live in loose colonies with interconnected burrow systems for shelter. They exhibit territorial behavior around food sources and burrows, communicating through vocalizations and tail movements. They are agile climbers on rocks and plants, often basking in the sun to regulate body temperature.
Conservation Status
The IUCN classifies the Espiritu Santo antelope squirrel as Vulnerable due to habitat loss from invasive species and human activities like tourism. Population trends are decreasing, with ongoing threats from predation by introduced animals.
