Mexican Duck Photo Essay

The Mexican Duck, Anas platyrhynchos diazi, was recognized as a full species (then A. diazi) until the American Ornithological Society (AOS; then AOU) merged it with the Mallard (AOU 1983), largely based on data from Hubbard (1977). However, recent genetic studies strongly suggest that the Mexican Duck should be returned to full species status. These photos are intended to provide a realistic overview of the challenge of identifying Mexican Ducks in the ABA Area.
