Abstract : A review and synthesis of existing information were used to develop a habitat model for redhead (Aythya americana). The model is scaled to produce an index of habitat suitability between 0 unsuitable habitat) and 1 (optimally suitable habitat) for redhead wintering habitat along the northern Gulf of Mexico. Habitat suitability indices are designed for use with habitat evaluation procedures previously developed by the U.S. Fish and Wildlife Service. Guidelines for model applications and techniques for estimating model variables are described.
