The Upper Chesapeake region is one of the more important areas in North America for migrating and wintering waterfowl. Conditions here affect the welfare of waterfowl populations in the entire Atlantic Flyway. During the more recent years of this study there was a noticeable decline in the waterfowl populations in this region, probably as a result of destruction and disturbance of habitat along with a steady increase in hunting pressure. The purpose of this report is to present information on the distribution, ecology, and harvest of waterfowl in the Chesapeake Bay Region, so that this information can be used as a guide to management and preservation of waterfowl populations.
