HENSHAW, Chief DISTRIBUTION AND MIGRATION OF NORTH AMERICAN SHOREBIRDS BY WELLS W. COOKE Assistant, Biological Survey WASHINGTON GOVERNMENT PRINTING OFFICE 1910 LETTER OF TRANSMITTAL. U.S. Department or AGRICULTURE, Brotocicat SuRVEY, Washington, D. C., June 28, 1910. Sir: I have the honor to transmit herewith, for publication as Bulletin No. 35 of the Biological Survey, a report on the Distribution and Migration of North American Shorebirds, by Wells W. Cooke, assistant, Biological Survey. Many species of shorebirds inhabit the United States or pass through our territory in migration. These birds possess considerable economic importance, and as other wild game like ducks, geese, and swans diminish in numbers their value for food and as a means for sport will increase. J.arge numbers are annually killed, and unless prompt measures are taken adequately to protect them some of the larger and more important kinds are likely to become extinct, especially in the region east of the Missis- sippi River. A knowledge of the summer and winter abodes of the several species and of the routes they take in migration is essential to intelligent legislation in their behalf, and, accordingly, all the known facts in regard to this part of their life history are here brought together. Respectfully, H. W. Hensnaw, Chief, Biological Survey. Hon. James WItson, Secretary of Agriculture. 2 CONTENTS.
