London: Christopher Helm/A & C Black, (2008. second edition). Large octavo, colour plates, distribution maps, fine copy in dustwrapper.
This revised second edition (first published 1999) covers the identification of owls of the world. 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.
An accompanying CD of owl vocalisations is in planning for late 2009/early 2010 see [stock id 13247].
