A study of nesting success of pheasants (Phasianus colchicus) on three areas in central Iowa in 1961 showed that the peak of nest establishment occurred between May 16 and May 30. Hatching success varied inversely with pheasant population density. Twenty-four of the 96 nests found hatched successfully. Roadsides sheltered the highest percentage of nests on a per acre basis (46 nests/100 acres), followed by hayfields (24 nests/100 acres) and oatfields (4.7 nests/100 acres). Idle land and fence rows contained the fewest number of nests. Most nests were located in cover from 16 to 22 inches in height. No significant relationship was found between the height and/or density of cover and the success of the nests. Farm machinery operations, especially hay mowing, caused the greatest destruction of nests.
