REGULATION OF PHEASANT DENSITY THROUGH NEST ABANDONMENT IN SOUTH-CENTRAL NEBRASKA
Abstract
In a five-year study of the ring-necked pheasant (Phasianus colchicus) in south-central Nebraska, Linder, Lyon and Agee (1960) proposed that "the quality of nesting environment determines the number of nests which will be successful in a given year; this regulates total production which in turn determines the following year's breeding population." These conclusions were based upon the following findings;1. A close correlation existed between the estimated number of chicks produced and the number of hens the following spring. Because of this relationship it was proposed that mortality was quite constant from year to year and the nesting season was the factor limiting the population in the area studied.2. The number of chicks produced was not a function of the number of hens in the breeding population; rather, total production was apparently predetermined by the nesting environment, xvhich appeared to limit the number of nests which were successful each year. Concomitant with this, the principle of inversity (Errington, 1951) was illustrated since fewer chicks per hen were produced as the breeding population increased.
