Abstract

In order to determine some of the factors influencing waterfowl abundance in eastern Iowa, field studies were made of migrating ducks during the years 1940-1945. A study area was selected on the Mississippi River 20 miles north of Davenport, Iowa, and near the town of Princeton, Iowa. The study area, a low-land meadow and marsh, is 5 miles in length and 1½ miles in width. It is known locally as the Princeton Marsh. Additional observations were made at scattered points along the Mississippi from Dubuque south to Keokuk, Iowa; on the Wapsipinicon River for a few miles above its mouth; and on Rock River near Moline, Illinois.
