This text investigates the ecological and evolutionary mechanisms that facilitate the successful establishment and spread of non-native bird species in new environments. The authors, all established researchers in avian biology and invasion ecology, synthesize global data sets to construct a framework for understanding why certain species become invasive while others fail to persist. By examining the interplay between species traits, environmental conditions, and human-mediated dispersal, the book provides a comprehensive analysis of the biological factors governing avian invasions.

Experts recognize this work as a foundational text for understanding the biological drivers of avian colonization. Researchers frequently cite the book for its rigorous application of ecological theory to the specific challenges posed by exotic bird populations.
