Colombia is one of the most biologically diverse countries in the world: although it takes up slightly less than one percent of the Earth's surface, it is home to approximately ten percent of the world's plants and animals, including a diversity of primate species that is only superseded by Brazil and Peru in number. This vibrantly illustrated field guide is the result of field work conducted on Colombian primates both in and out of the country. The volume illustrates and describes twenty-eight primate species comprising forty-three taxa, of which fifteen taxa are only found in Colombia. The field guide also includes comprehensive chapters on primate classification, fossil history, and conservation, and each is augmented by numerous drawings, photographs, and maps. Primates of Colombia will be an invaluable resource for primatologists and naturalists alike.
