Spatio-Temporal Patterns In The Depredation Of Waterfowl Nests In The Prairie Potholes Region, Usa, Jennifer S. Borgo, Michael R. Conover

Wildland Resources Faculty Publications

Nest depredation is the leading cause of waterfowl nest failures in much of the Prairie Pothole Region, USA. In 2006 and 2007, spatial and temporal patterns of nest depredation were evaluated on 248 waterfowl nests and 88 simulated waterfowl nests in North Dakota, USA. The hypothesis that predators are able to locate adjacent nests using an area-restricted search once they find the first nest and that ducks will space their nests apart to reduce this from happening was tested. However, no evidence was found to support either part of this hypothesis or that density-dependent depredation was occurring. This lack of ...
