Chipmunks use a variety of sounds to communicate, although the most frequent—a high-pitched chirp sound—is often mistaken for a birdsong. They also emit a deep clicking sound, which alerts other chipmunks to danger.
Chipmunk tracks are difficult to locate as their feet are so small, but like most rodents they have four toes on their front paws and five toes on their bigger hindquarters. They tend to hop and bound as they travel which leaves a gallop pattern to their prints, with their hind paws landing before their front tracks.
Chipmunk poop is slightly larger than that of mice; dark, small and elongated with pointed ends, their poop range in size from half an inch to three-quarters of an inch. However, you rarely come across their droppings because chipmunks actually build special latrine chambers in their burrows to dispose of waste.
