May 2022 Photo Quiz

May 21st, 2022|

Not a very good photo this month. Right? While I generally try to have reasonably good photos with the quiz subject in reasonably good focus, birding is not really like that. We do not see most individual birds well, and, at least for those with “good ears,” most birds that we detect are not seen at all.

Advanced Identification

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.

This incredible identification feature is temporal likelihood, aka time of year.
