Vagrancy in Birds
Alexander Lees, James Gilroy
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.
