Owls : a guide to the owls of the world
Claus König (Author), Friedhelm Weick (Author, Illustrator), J. H. Becking (Author)
"Because of its adaptation to nocturnal life, the owl is sometimes difficult to see; its identification is therefore a challenge even to the most experienced field birders. This book, together with its accompanying double CD, is an invaluable aid to the identification of owls, for it pays particular attention to the crucial element of voice identification. In addition to identification, the book also offers in-depth coverage of the ecology and reproductive behavior of owls. The book includes 64 color plates of various species, line drawings and distribution maps."--Jacket
