In zoos, colonies of this species are like yeast — a few sent to another zoo soon reproduce to the carrying capacity of their exhibit, and more colonies can be established from there. From a few importations more than 30 years ago, there are now more than 6,000 of these fruit-eating bats distributed among more than 30 North American collections. This is a widespread species, found from Mexico to Paraguay.
