Hawks are among the most spectacular birds in North America, and there have been several raptor-identification books published in recent years—so why another? In 1988, Hawks in Flight, by Pete Dunne, David Sibley, and Clay Sutton, broke new ground in North America by taking raptor identification beyond Peterson’s field-mark system. Identifying raptors in flight is as much art as science, and it is difficult at best to convey what exactly it is that experienced hawk watchers use to name birds at long range, and at those real-life angles birds assume. Hawks in Flight still stands as a landmark, with numerous superb line drawings and a good number of (poorly reproduced) black-and-white photos showing hawks “as they really are.” Hawks from Every Angle also attempts to distill decades of hard-won knowledge into a field-friendly format. It is perhaps inevitable to liken Liguori’s work to a succinct, more standardized version of Hawks in Flight, with the benefit of color photos, but these differences are attributes and will help make Hawks from Every Angle the new bible for hawk watchers.
