Vagrancy in Birds explores both pattern and process in avian vagrancy, drawing on recent research to answer a suite of fundamental questions concerning the occurrence of rare birds: What causes vagrancy? Why do some places attract so many vagrant birds? Why are some species more predisposed to long-range vagrancy than others?
Vagrancy in Birds synthesizes everything that is known about the subject, and draw together different lines of evidence to make the case for vagrancy as a biological phenomenon with important implications for avian ecology and evolution.
