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 43 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 upto-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 these areas comprise a superspecies complex, with the precise relationships between various components still under considerable debate. A thorough illustrative and textual treatment of the group is needed, and this book provides the most recent and complete overview. This is the essential reference to a fascinating and challenging group of birds.
Armed with this book, you should be able to separate with confidence an American herring gull from a herring gull, and an Armenian gull from a Caspian gull. You might even put a name to a vega gull. -- David Tomlinson New Scientist It is hard to imagine there could be a better book. Quite simply, it is superb... [The] illustrations are of exceptionally high quality. Bird Watcher's Digest Will become the reference for gull identification in the Northern Hemisphere for many years. Choice This landmark new book ... will undoubtedly be welcomed by larophiles across the Northern Hemisphere. ve N. G. Howell," Birding Gulls of North America, Europe, and Asia represents a tough job well done... [I]t is not only a welcome addition but a near necessity in an ornithological library. -- J.R.

The book begins with the contents page listing all 43 species and corresponding page they begin on. Then the introduction covers the way the book is laid out and how to use and read the terminology, gull terminology is almost a language in itself. Gull topography is covered then four plates of comparison of large gull taxa this is followed by six plates on wingtip patters, quite handy when comparing several large taxa of gulls.
Then begins the species accounts. Loads of information concerning each species is covered with identification of plumages in adult summer, winter, juvenile and the many following summer and winter moults till adult is reached. The moult is described as is a description again covering the many plumages these birds go through. Distribution and migration is covered then measurements and weights. Each species account comes with a small box with the basics of the gull and the basics of each year’s plumage, like a quick reference guide. Color range maps show breeding and non-breeding range including subspecies range where needed.
Each species has one or two very good plates depicting the resting and flight views plus the many plumages. Facing each plate are the key features of each plumage with the corresponding months these plumages occur. The plates are augmented by many color photographs again depicting the many moults and plumages seen on the specific age of the bird. At the back there are three additional references to gulls that have reached North America.
Anyone with the desire to scan flocks of wintering gulls looking to discern the ages and moults of certain species has just found their bible. Exceptional coverage of these birds in pain staking detail is covered in this extensive tome on one of the most challenging families of birds. Now all we need is someone to do the same for the southern hemisphere.
A caution though: gulls can be notoriously difficult to identify accurately, since they have so much finely detailed, age-related plumage variation. But an effort to simply knuckle-down and learn more about all this, such as this book amply provides, can pay off greatly in much greater detective-fun trying to figure out all these heretofore anonymously gray gulls sailing and prowling around us here each year. It's already helped me develop better skills in figuring out nearly all the varied groups of gulls around us here more quickly than I would have heretofore thought possible. And to more quickly decide which birds you can or cannot more accurately identify...and why.
The detailed accounts and maps of the distribution and relative abundance of various gull species have also helped me better understand where the gulls that migrate through or winter in our area are likely to have come from. And, finally, as you delve more deeply into what's known about all these gull species, and their European and Asian counterparts, it becomes obvious that the series of beautiful, comparative paintings and color photographs provided in such detail for each species in its various age-plumages, subspecies, and hybrid-forms is worth the price of the book alone.
