This is a completely new in-depth field guide to the 1,070 bird species, including North American migrants, found in Mexico, Guatemala, Belize, El Salvador, Honduras, and western Nicaragua. More than 180 species are endemic to this region and the book details their appearance, voice, habitat, behaviour (including nests and eggs) and distribution. 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's striking 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.
