Skuas (and jaegers) are a fascinating and popular group of seabirds that make up a subfamily of just seven species. They can be divided into two main groups: the larger species of Catharacta skuas which are mainly found in the southern hemisphere (with Great Skua breeding in the north), and the three Stercorarius species (also known as jaegers) which breed in the northern hemisphere. Both northern and southern skuas breed at high latitudes and several species are long-distance migrants, performing spectacular migrations through most of the world's oceans, sometimes even flying...

Until recently, gulls were a group that inspired dread among birders, due to the bewildering variety of plumage, age groups, and races, many of which are very difficult indeed to separate, even to species. Things changed in 2003 with the publication of Klaus Malling Olsen's Gulls of Europe, Asia and North America, a plate-based title that made accurate identification of gulls a realistic possibility for the first time. Gulls of the World is a companion and successor to that seminal work.

This photographic identification guide covers all of the world's gull species,...

The publication of The Sibley Guide to Birds, First Edition quickly established David Allen Sibley as the author and illustrator of the nation's supreme and most comprehensive guide to birds. Used by millions of birders from novices to the most expert, The Sibley Guide became the standard by which natural history guides are measured. The highly anticipated second edition builds on this foundation of excellence, offering massively expanded and updated information, new...

Amateurs and professionals studying birds at the end of the nineteenth century were a contentious, passionate group with goals that intersected, collided and occasionally merged in their writings and organizations. Driven by a desire to advance science, as well as by ego, pride, honor, insecurity, religion and other clashing sensibilities, they struggled to absorb the implications of evolution after Darwin. In the process, they dramatically reshaped the study of birds.

Daniel Lewis here explores the professionalization of ornithology through one of its key figures: Robert...

Ten Thousand Birds provides a thoroughly engaging and authoritative history of modern ornithology, tracing how the study of birds has been shaped by a succession of visionary and often-controversial personalities, and by the unique social and scientific contexts in which these extraordinary individuals worked. This beautifully illustrated book opens in the middle of the nineteenth century when ornithology was a museum-based discipline focused almost exclusively on the anatomy, taxonomy, and classification of dead birds. It describes how in the early 1900s pioneering individuals...
