The confusing part is, that the AOU checklist committee didn't accept Mexican Duck as a full species (as far as I can tell). The ABA Checklist committee always follows AOU on split species. So, I'm thinking that Mexican Duck doesn't count any lists submitted to ABA Listing Central (is that correct)?? So, Mexican Duck can't be added to the Colorado State List, if it isn't a full species, according to AOU.
