Overall, this is a comprehensive, up-todate, and exciting book. It provides a much-needed stimulus for a greater focus on avian invasions and their effects on native biodiversity, but it also illustrates how the study of exotic birds can help to advance our general understanding of invasion ecology. I predict that it will become a classic text in invasion ecology, and I strongly commend it to all who are interested in this important and growing field. * PLoS Biology * In this book, three leading experts combine theory with a rigorous analysis of the evidence to ask what are the causes and consequences of avian invasions. And they succeed formidably. The book is a must read for anyone interested in biological invasions, and will inspire students and academic researchers alike. It is informative, comprehensive, rigorous, stimulating and highly readable. * Trends in Ecology and Evolution *
