商品簡介
Sylvia Warblers describes in detail identification (in the field and in the hand), ageing, sexing and moult of all species of Old World warblers in the genus Sylvia. This, combined with DNA information on systematic relationships, makes this guide unique among modern bird books and truly a landmark publication.
The book contains original and unpublished data, compiled from field studies and meticulous museum research. Twenty colour plates, painted by Alan Harris, and 546 colour photographs provide an exhaustive visual reference unmatched in any other publication to date. There are hundreds of diagrams, tables and figures illustrating moult sequences, wing formulae, jizz and other aspects of identification and behaviour, while large-scale colour maps show the distribution of each species.
