A California ground squirrel (Otospermophilus beecheyi) stuffs its cheek pouches with hazelnuts gathered from a farmer's harvest on a ranch near Elkton in rural southwestern Oregon on October 10, 2025. The species is known for its expandable cheek pouches, which allow it to transport food back to its burrow for storage. (Photo by Robin Loznak/ZUMA Press Wire/Rex Features/Shutterstock)
