This book examines behavioral adaptations of tropical birds in timing of breeding, life history traits, mating systems and parental care, territoriality, communication, and biotic interactions, and emphasizes the many gaps in our knowledge of tropical birds. We urge students and researchers in temperate and tropical regions alike to realize the potential they have for improving our knowledge of avian adaptations far beyond what is currently accepted as gospel. Time is running out. * Line drawings with graphs * Unpublished data and observations from decades of authors' research in tropics.
