Bats of the Virgin Islands in relation to those of the Greater and Lesser Antilles. American Museum novitates ; no. 2581 Koopman, Karl F. Abstract: "The bats of the Virgin Islands (including Vieques and Culebra) are discussed in relation to distribution, feeding, and roosting habits. The bat fauna of these islands is compared with those of the northern Lesser Antilles and Puerto Rico and it is concluded that the Virgin Island bat fauna is a depauperate derivative of that of Puerto Rico. Of the eight passages of bat species here discussed between the Greater and Lesser Antilles, four probably went from west to east, three from east to west, and one is indeterminate" 1975.
