"Common and widespread from far southern Canada throughout most of the United States and Mexico, and farther south through Central America and into South America, the red bat requires trees and shrubs for roosting. It is remarkable for its richly-colored reddish pelage, with the male brighter than the female. Although the red bat is solitary, it migrates in groups. Females often give birth to twins and sometimes to quadruplets. The young are born hairless, with eyes closed, and weigh only 0.5 g, but by 3-6 weeks they are covered with fur, have their eyes open, are half their mother's weight, and can fly."
