A model of habitat use of breeding American black ducks

A linear-logistic model of habitat use was developed for Anas rubripes breeding in Maine. The model predicted wetland use by black ducks using perimeter of surface water, area of flooded timber, presence or absence of beaver Castor canadensis, and visibility of an occupied, human dwelling. The model was robust and had an overall correct-classification rate of 80%. Management of beaver populations possibly affects quantity and quality of waterfowl habitat. An increase in housing developments could have an adverse effect on the quality of wetland habitats. -from Authors
