Book Description
This eagerly awaited guide offers the most comprehensive treatment ever published on the gulls of Europe, Asia and North America. A total of 43 species is treated, and every species is described in considerable detail, with a full description of each plumage and racial variation. Gulls are intelligent, versatile, opportunistic, and ecological generalists. As such, they exploit a variety of habitats, both coastal and inland, take a wide range of food, and are often extremely abundant. They are also great wanderers, with several American species regularly appearing in Western Europe and vice versa. As well as identification criteria, this book includes an up-to-date assessment of the range and status of every species, together with information on patterns of vagrancy. This important guide is published at a critical time in the development of dull taxonomy. The large, white-headed forms occurring in the region comprise a superspecies complex, with the precise relationships between the various components still under considerable debate. A thorough illustrative and textual treatment of the group is much needed, and this book provided the most complete overview of the complex. The text is complemented not only by superb colour paintings by Hans Larrson, but also by a large selection of colour photographs, sourced from some of the finest bird photographers in the world. This is the essential reference to a fascinating and endlessly challenging group of birds.

Book Description
Although they are familiar and amusing characters, gulls are frequently dismissed as common "parking lot" birds or because their diverse species can be hard to identify. Both assumptions disregard the beauty and grace of gulls, which are among the most approachable of North America's birds. This photographic field guide provides a user-friendly introduction to the plumages of 27 North American gull species in different stages of maturity. Ranging in size from the dove-like Little Gull to the eagle-like Great Black-backed Gull, their behavior and habitats are equally varied. With more than 500 color photos, detailed captions, and fold-out comparison guides, this book allows readers to better appreciate these charismatic birds by learning shortcuts for easy identification in the field.

The gulls are a large family of seabirds, familiar and distinctive as a group, but one of the most challenging to separate at the species level, especially in their various stages of immature plumage. This guide offers the most comprehensive treatment ever published on the gulls of North America, Europe, and Asia. Klaus Malling Olsen and Hans Larsson treat a total of forty-three species--each depicted in considerable detail, with a full description of every plumage and racial variation. The text is complemented not only by superb color paintings by Larsson, but also by 800 color photographs. Gulls explore a variety of habitats, consume a wide range of food, and are often extremely abundant. They are also great wanderers, with several American species often appearing in Western Europe and vice versa. As well as identification criteria, this book includes an up-to-date assessment of the range and status of every species, together with information on patterns on vagrancy. This important guide is published at a critical time in the development of gull taxonomy. The large white-headed gulls found in North America, Europe, and Asia comprise a superspecies complex, with the precise relationships between various components still under considerable debate.

This is the essential reference to a fascinating and endlessly challenging group of birds.
