This book serves as the 54th annual report for the United States Department of Agriculture's Biological Survey, a bureau established in 1885 to research wildlife. The report reviews the year's activities in wildlife restoration and conservation, including notable improvements to national wildlife refuges and the acquisition of dedicated wildlife habitats. The author highlights key trends in wildlife populations and shares ongoing research into the status and management of migratory waterfowl, and provides updates on research into the wildlife of Alaska, Mexico, and the United States.
