The opening of the book presents the author's aspirations and methods for studying the avian life across the Rocky Mountains, emphasizing a fascination with both the unique species found at different elevations and the migratory patterns that differ from those of eastern North America. Keyser describes encounters with various birds, such as the white-crowned sparrow and western robin, while also discussing the influence of altitude on their habitats and behaviors.
