There has long been a demand for a popular book on the birds of the Canal Zone. Americans resident in the Zone familiar with their own home birds, wish to make friends with the feathered folk of their new surroundings but hitherto there has been no one volume that would help them to achieve this end.During her three year's residence in the Zone Mrs. Sturgis herself experienced this want and after returning to the United States, where material for study was available, she filled it with the present volume. Local variations in the distribution of bird-life often make it impossible to draw the line between species that, regionally, are common and those that are rare. To meet this difficulty Mrs. Sturgis has included in her work descriptions of all the birds known from the Zone. Her book, therefore, should be useful to beginners as well as to more advanced students, and it may also assist those who wish general information about tropical American bird life.
