Range maps are included with species accounts, and introductory essays give essential background information, with special appendices summarizing useful information on the avifaunas of various offshore Pacific and Caribbean islands. The Guide'sstriking illustrations include 71 colour plates and 39 black-and-white drawings, based on the authors' field experience and in many cases detailing plumages never before illustrated. Authoritative and up-to-date, this is an essential reference work for every birdwatchers' collection.
