This chapter considers patterns of evolution in exotic bird populations. Evidence is presented that exotic birds have evolved in their phenotypes over the relatively short time spans in which they have been established in their new locations. Some of the shifts observed are entirely consistent with macroevolutionary patterns observed amongst native bird species; others are more curious and require reconsideration of some long-held views of evolutionary dynamics. The chapter notes the great potential for research on the evolution of exotic birds to provide insight into basic evolutionary theory and the role of evolution in the impacts of all invasive species.
