This outstanding new guide covers all of the world’s gull species, tackling some of the most notoriously difficult identification and taxonomic challenges in birding. Concise text – complemented by an accurate colour range map – places particular emphasis on field identification, with detailed discussion of variation, and coverage of habitat, status and distribution. Each photograph has been carefully selected to highlight identification criteria and, crucially, to allow age and subspecific separation in the field. This book is an invaluable tool for identifying gulls, featuring the most sought-after rarities as well as beautiful, easy-to-identify species.
Klaus Malling Olsen is without doubt the world’s foremost and best-known gull expert. His previous books include Gulls of Europe, Asia and North America (2003), which remains the standard work on gull identification, more than ten years after its publication.
