Pages : 674
Book Description
The successful operation of the Federal Migratory Bird Treaty in according protection, hitherto uncertain, to migratory game and insectivorous birds, with resultant increase in many species, leads naturally to inquiries regarding the present status of birds that migrate in winter beyond our borders. Since observation of shore birds was the main point in mind, travel was restricted largely to the level sections where suitable shores and marshes were available, so that collections were made in the main in the lowlands.
