Secretary of the Interior's State of the birds report assessed the distribution of birds on nearly 850 million acres of public land and 3.5 million square miles of ocean. It relied on high-performance computing techniques to generate detailed bird distribution maps based on citizen-science data reported to eBird and information from the U.S. Geological Survey's Protected Areas Database of the United States. The report provides  assessment of the distribution of birds on public lands and helps public agencies identify which species have significant potential for conservation in each habitat. The state of our birds is a measurable indicator of how well we are doing as stewards of our environment. The report stresses the need for greater conservation efforts on public lands and waters to realize the vision of a nation sustained economically and spiritually by abundant natural resources and wildlife.
