This comprehensive guide includes multiple photos of every owl found in North America, including some regional subspecies. Some species have up to six photos that show plumage variation, sexual differences and behavior, with 75 photos representing the 19 species of owls found in North America.
Most other similar guides only show two or three photos of each species, which is why this guide is more helpful in field conditions.
Accompanying text provides tips on how to identify each owl, including how they differ from other similar owls, as well as their calls and vocalizations. The ability to see similar owl species in side by side comparison is the key to your ID success, and this guide allows that to happen due to the foldable panels.
Nine species of nighthawks and nightjars are also shown at the end of this guide, with multiple photos showing nighthawks in flight for ID comparison. All nightjars found in North America are also shown here, with text explaining how each differs from the others. This waterproof guide is invaluable for your field identification of these two birds groups.
