Interpreting Evidence of Depredation of Duck Nests
in the Prairie Pothole Region

Part II: Evidence of Depredation by Predator Species

Depredation Patterns of Predator Species


In Part II, we describe responses to nests, affect on hens and eggs, and evidence of depredation at or near duck nests by the principal predators of duck nests in the Prairie Pothole Region. Accounts are based on literature (Appendix A) and on verification data gathered intermittently during 1972-92. A comparative summary of the relative importance of certain evidence as indicators of depredation by each of the principal predators is in Appendix B, Table 2.
