Skuas are a wide ranging group of seabirds; some are found as far south as the Antarctic and others in the Arctic regions of the world. They are one of the most challenging groups of birds to identify because of variation in plumage according to the age of a given bird and conditions for identifying them. This book--the first complete guide to the skuas of the world--was designed to enable species identification and correct aging of these birds.

Stercorariidae, Skuas and Jaegers - English
URL: http://www.nzbirds.com/Skuas.html

Whereas the gulls have long had an established taxonomy, with little argument about relationships, there is not yet any consensus about how the skuas are related and how they should be named. In part this uncertainty derives from their distribution, small to moderate numbers of birds spread widely among islands and continental habitats, in part because at least for the great skuas, there has apparently been a very recent (in evolutionary terms) radiation across the Southern Hemisphere, with a single group in the Northern, so that there is not yet great distinctiveness.
