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.
