This book is an overview of our bats, for children, where common names, scientific names, descriptions, feeding, distribution and conservation are detailed. It is profusely illustrated with full color drawings, as well as distribution maps in Cuba. The field guides constitute a form of scientific popularization, already classic in the world literature of natural sciences, devised so that the amateurs have the means in the quick identification, in field conditions, of a particular group of animals, of a determined country or region. Obviously, they are characterized by an appreciable predominance of illustrations at the expense of the text. Works of this type are in great demand among the population. The author is a specialist in the study and conservation of Cuban bats.
