North American owls

the long version

"Paul Johnsgard has completely updated his highly praised 1988 edition of North American Owls, and by adding twelve species of Mexican owls he now covers the entire continent of North America.". "This second edition presents updated information, new and modified figures and range maps, and twelve new color plates, including illustrations of Mexican owls. The number of citations has nearly doubled to 900, reflecting more than a decade's worth of scientific inquiry and discovery. As with the original North American Owls, this second edition will become the standard work in the field."--BOOK JACKET.
