The Iowa Cooperative Wildlife Research Unit has conducted research on the ring-necked pheasant (Phasianus colchicus) since 1935 on the Winnebago Research Area. From 1939-41 intensive nesting studies were made (Baskett, 1947) and again from 1950- 54. However, during this latter period, other investigations curtailed a complete nesting investigation, and it was not until 1954 (Klonglan, 1955) that time was available for a complete study with comparable spring pheasant populations. Since fall pheasant population levels in the 1939-41 period were estimated at 140 to 400 birds per section as compared to 100 to 110 birds from 1950-54, an intensive nesting study was deemed advisable for comparative purposes.
