Mottled Duck Anas fulvigula*
*The ducks I saw are Mexican Ducks,
diazi. I had never heard of these before today when I was going through my 'to be identified' pics and came upon a photo of a pair of very dark ducks which I assumed where American Black Ducks until I realized Arizona is far outside of that species' range. Apparently Mexican Ducks are a taxa which have most often been lumped as a population of Mallard but appear to be more closely related to American Black Duck. HBW lists them as a subspecies of Mottled Duck but there seems to be growing support for them to be split into their own species. Since I don't think I'm allowed to count them as a separate species just yet I'll simply include them as Mottled so I still get a tick and still get a lifer

(and because I generally follow HBW's rulings anyway). Animals pictured below:
