This atlas provides a breeding distribution snapshot for each of Arizona's nesting bird species at the end of the twentieth century. Bird populations change constantly due to environmental factors and human activities. The data compiled in this book will serve as a baseline against which to judge future changes. It also provides a wealth of natural history information.
Each of the 270 two-page species accounts contains a color photo of the species and a range map summarizing the breeding distribution records collected during the atlas survey period. The accompanying descriptive text and graphs provide nesting habitat information and a timeline chronicling each bird's breeding phenology and migratory status in Arizona. Another 47 species are briefly discussed. Additional chapters describe atlas methods, results, and Arizona ornithological history, as well as topography, climate, and habitat diversity, which ultimately govern bird species distribution in the state. Useful to land managers and biologists, the atlas will also be a resource for birders and educators and will increase public awareness of Arizona's vast avian life.
Section headings: Introduction -- Organisation and Methods; Geography, Climate and Habitats of Arizona; A Brief History of Arizona Ornithology; Species Accounts; Appendices; Index of English Bird Names.
