Owls of the World
Owls are enduringly popular birds, but due to their nocturnal habits
most species are difficult to see well. The plumages of many species
are cryptic and difficult to separate by plumage alone. This problem is
compounded by the different morphs that many adopt. This book fully
describes every known species and subspecies of owl, as well as
presenting the latest evidence on owl taxonomy, based on DNA work and
vocalisations. Because voice is vital in owl identification, much
emphasis is placed on it in the book and sonograms are provided for
many species. A CD of owl vocalisations will accompany the book.
