Sylvia Warblers describes in detail identification (in the field and in the hand), ageing, sexing and moult of all species of Old World warbler in the genus Sylvia. No other book has provided such an abundance of detail on these aspects for any genus of birds, nor the quality and number of illustrations showing individual and geographic variation.

Identification, Taxonomy and Phylogeny of the Genus Sylvia

Sylvia Warblers

Andreas Helbig

Based on phylogenetic research, this complete study of the genus Sylvia describes two new species and establishes identification criteria for all members of the family. A lengthy introduction explains the background to the research and outlines the main features of the genus. The 25 species are then treated in detail, including the African parisomas, which are here included in the Sylva group. The species accounts include sections on every aspect of identification, with colour illustrations showing age, sex and racial differences, distribution maps, sonograms, moult and wing diagrams and tables."
