Are Chipmunks Nocturnal?
Chipmunks are diurnal and rely on sunlight and their specialized vision to detect moving shadows as a main defense. Chipmunk eyes aren’t equipped for night vision, but they can see in the dark and aren’t totally blind.
Chipmunk eyes perceive a world that is faster and larger than the one humans see, allowing them to quickly respond to stimuli and threats. They retire into their burrows at sunset. Chipmunks design elaborate burrows, up to 30 feet long, to dwell and sleep in. They use grass and leaves as bedding and excavate a separate area to keep the food stores in.
