# Vagrancy in Birds - Hardcover

by **Alexander Lees** (Author), **James Gilroy** (Author)

**An exploration of the causes and patterns of avian vagrancy**

Avian vagrancy--the appearance of birds outside of their expected habitat--is a phenomenon that has fascinated natural historians for centuries, from Victorian collectors willing to spend fortunes on a rare specimen to today's bird-chasing "twitchers." Yet despite the obsessions of countless ornithologists, what do we actually know about the enigma of vagrancy? In _Vagrancy in Birds_, Alexander Lees and James Gilroy explore the causes, patterns, and processes behind the occurrences of these unique birds.

Lees and Gilroy draw on recent research to answer fundamental questions: What causes avian vagrancy? Why do some places attract so many vagrant birds? Why are some species more predisposed to long-range vagrancy than others? The authors present readers with everything known about the subject, and bring together different lines of evidence to make the case for vagrancy as a biological phenomenon with important implications for avian ecology and evolution.

Filled with a wealth of photographs, _Vagrancy in Birds_ will fascinate avian enthusiasts everywhere.
