Abstract or Summary
  • Rates of predation on artificial nests and nests of pen-reared ring-necked pheasants (Phasianus colchicus), released in spring, were compared between strip and block habitats at different densities of nests. Nests in strips had rates of predation 4-7 times greater than nests in blocks, regardless of nest density. Differences between successful and depredated nests were due primarily to differences in habitat pattern rather than structural characteristics of vegetation at nest sites. Predators may be able to control prey populations in habitats where prey are concentrated and effectiveness of predators is high, therefore predation could be viewed as acting in a density-independent manner.
