A large, elegant tree squirrel native to the western United States and parts of nearby Mexico. It is known for its soft silver-gray coat, bright white belly, and long, full tail with white edging. Compared with the smaller and more common eastern gray squirrel, the western gray squirrel often looks bigger, paler, and more graceful. It is also usually more shy and less comfortable in busy city life.

One thing that makes the western gray squirrel special is its close relationship with oaks. Acorns are one of its most important foods, especially in autumn, but it also eats pine seeds, berries, fungi, buds, flowers, and other plant foods. Like many tree squirrels, it may bury food for later. Some forgotten acorns and seeds can grow into new trees, which makes this squirrel a quiet forest helper. Its strong claws and long tail make it excellent at climbing, balancing, and leaping through branches. When alarmed, it may flick its tail, give warning calls, or quickly disappear into the trees.

The western gray squirrel differs from many familiar backyard squirrels because it usually prefers mature forests and woodlands rather than crowded urban areas. It often needs connected tree cover so it can travel safely above the ground. Its large tail is not just for beauty; it helps with balance, warmth, shade, and communication. It also builds leafy nests high in trees, often using twigs, leaves, moss, and bark. These nests provide shelter for resting and raising young. In colder or wetter seasons, a warm, well-hidden nest can make a big difference.
