Book excerpt: This book is devoted to the Little Bustard, a medium sized Paleartic steppe bird whose distribution ranges from the Iberian Peninsula to Central Asia. At present, the European population is suffering a severe decline mainly due to agricultural intensification, although its status and concerns in non-European countries are relatively unknown. In spite of this dramatic situation, the Little Bustard is an interesting model species for topics as varied as phylogeny, life history evolution and demographic traits, sexual selection and lekking behavior, habitat selection, intra- and interspecific relationships, or interaction with farming and other anthropogenic disturbances. This book provides an updated, interdisciplinary, and worldwide review of the most recent information of this crucial species in the Palearctic steppe-bird community, from specific biological aspects and traits to research-focused management. Some of the most prominent scientists from different fields (systematics, breeding ecology, behavior, competence, predation, population dynamics, farming, conservation) update and synthesize the existing information on a singular, threatened and vulnerable species.
