Factors Influencing Depredation of Artificial Duck Nests
Esler D and Grand JB. 1993. Factors Influencing Depredation of Artificial Duck Nests. The Journal of Wildlife Management. 57(2):244-248
Because artificial nests can facilitate controlled experiments of nest success, we used them to assess whether human visitation, nest density, vegetation structure, and proximity to habitat edge could affect depredation of duck nests on Yukon Flats National Wildlife Refuge, Alaska. More (P 0.05) between depredated and undisturbed nests. We suggest that daily visitation of duck nests increases depredation, but longer intervals, typical of most nest studies, do not. High nesting densities, which could occur when flooding limits nesting habitat, may result in higher depredation rates.
