Discussion Completely terrestrial. Most abundant and commonly encountered salamander throughout much of its range. Because of its ability to tolerate cold the Red-backed has survived in glaciated areas of northeast United States and southeast Canada. During the day it hides under stones or woodland debris. At night it searches amid moist leaf litter for tiny invertebrates. During warm spells in winter it may be found at the surface. In dry weather it retreats underground and only surfaces after rainstorms.
