Birds of the Rockies

"Birds of the Rockies" by Leander S. Keyser is a scientific observation that explores the bird species thriving in the Rocky Mountain region. This work is a blend of a field guide and scientific study. It examines the special ways these birds have changed to live in different heights and climates. This also shines a light on their migration habits, how they breed, and ways to tell apart the birds that are local to Colorado and close by. The book starts with the writer's goals and how he plans to discover the birdlife in the Rockies, showing he is amazed by the special types he finds at all ground levels and how their moving patterns are not like those in eastern North America. Keyser tells of seeing different birds, like the white-crowned sparrow and western robin, and talks about how altitude affects where they live and what they do. Combining his own stories with scientific facts, Keyser crafts a fascinating introduction to the bird world of the Rockies.
