Book excerpt: Many warblers are notoriously difficult to identify in the field (and even in the hand!) and, until now, there has been no definitive guide to the species of these regions. This guide covers 145 species, covering all aspects of identification. The text includes sections on moult, voice, habitat and behaviour, distribution and measurements. All species (and many races) are illustrated within the 48 colour plates, and there is also a colour distribution map for each species, with a wealth of line drawings complementing the text. Many groups and species of warbler, such as prinias and tailorbirds, have never been described or illustrated in this detail before. Moreover, the book covers recently described series new to science and brings up to date the latest thinking on taxonomic treatment.
