Big Free-tailed Bat, Nyctinomops macrotis

The big Free-tailed Bat (Nyctinomops macrotis) can be found in South, Central, and North America. They prefer to roost in rocky crevices in rocky canyon country. It has an average body length of 5.5 inches. Little is known about the life span and mortality rate of the big free-tailed bat, but it is thought that breeding occurs during the winter, when the bats have migrated to warmer areas. Females will form nursery colonies and have one pup each. The pups will not leave the colony until they are almost full-grown. There is not much knowledge on the diet of the big free-tailed bat, but they seem to eat mainly moths. The bat will leave its roost in the evening to forage at high altitudes. The big free-tailed bat is a skilled, powerful flier with a wingspan of 17.1 inches.
