Sylvia Warblers Identification, Taxonomy and Phylogeny of the Genus Sylvia
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.
