Every year, millions of migratory birds follow ancient aerial pathways that stretch across North America - natural highways in the sky linking Arctic tundra and boreal forests of Canada and Alaska with the wetlands, prairies, coasts, and lagoons of the United States and Mexico. In Highways In The Sky, The North American Flyways, acclaimed photographer, author, and former wildlife biologist Gary Kramer takes readers on a breathtaking photographic journey along the four great flyways - Pacific, Central, Mississippi, and Atlantic - revealing the wonder, beauty, and complexity of bird migration.

The book showcases 915 exceptional photographs that portray waterfowl and shorebirds across their breeding, migration, and wintering habitats. Creating this work required extraordinary dedication. Kramer traveled more than 100,000 miles by commercial aircraft, thousands more by vehicle, and many additional miles by boat, small aircraft and on foot to reach locations throughout North America.

Kramer's decades of field experience and deep passion for wildlife and their habitats bring authenticity and depth to every page. Highways In The Sky is both a visual masterpiece and a celebration of one of nature's greatest journeys - an essential volume from one of North America's most respected voices in wildlife photography and natural history.
