Any doubt that this is a duck? Happily, most downy waterfowl are encountered in the presence of their more easily identified parents (in ducks, usually the mother); but many ducklings have such distinctive down patterns that they can be identified even on their own: some are even beautiful, and you should never pass up a chance to see, for example, Northern Pintail or the skunk-like young of Black-bellied Whistling-Duck.
Compared to those snazzy species, the quiz birdlet is quite plain. The white secondaries and tertials show up as a clear bar, and there is a whitish patch at the base of the rump. The head is pale, with a dark crown, a clear and narrow eyeline continuing across the lore, and a less conspicuous black bar across the rear auriculars.
That head pattern is seen only among some of the dabbling ducks; divers (and wigeon, too) are plainer, showing either a big white cheek or an essentially unmarked head and neck. Among the dabblers, some, such as Northern Pintail or Green-winged Teal, have faces crossed by two stripes. The "standard" pattern shown by the quiz bird is truly typical only of the mallards, including Northern Mallard, American Black Duck, Mottled Duck, Mexican Duck, and the "island" mallards.
According to Nelson's Downy Waterfowl, an essential and inexpensive reference, the hint of orange on the feet and the neat "widow's peak" on this bird's forehead suggest Northern Mallard rather than any of the "hen-plumaged" taxa. The obviously white belly of this bird also rules out Mottled and American Black Ducks. The presence of an auricular bar, the complete eyeline, and the foot color are probably enough to identify this bird as a Northern Mallard duckling.
Looks like your basic mallard duckling, to me. The pale yellow face with the dark, narrow horizontal stripe across the eye is a dead cert, and the pale splotches on the dark body and wings.
They are dead cute as ducklings, although they are mucky creatures. Used to raise 'em.
No idea. I don't have a field guide that shows duckling plumages. The markings on the wing are interesting; I don't recall seeing anything like that on the baby mallards I see in the courtyard fountains at the office park where I work, so I'll stick my neck out and say, "not a mallard". But other than that, I've got nothing.
Heh. Should have quit when I was at "no idea".
Well, I guess it's one sort of LBJ.
Mallard. That face with the stripe across the eye is indeed the giveaway.
john -- don't be discouraged! when i was teaching, i loved to see my students try, and even when they were wrong, they were usually the ones who ended up with the most solid knowledge because being incorrect increased their recall tremendously. putting these mystery birds here and having you all really look at them is a very good way to learn how to recognize THEM, so even when an individual of a particular species is out-of-range, you'll still be able to ID it in the absence of habitat cues and same-species interactions.
If it looks like a duck, and it sounds like a duck...
Another duck! Slightly cuter than the last duck.
Mallard is a good guess, though.
Well, it's obviously the cute bird!
Most or all of the baby dabbling ducks have a similar head pattern, but to me it looks like it'll grow up to be a beautiful Cinnamon Teal. It just looks Blue-wing/Cinnamon Teal-ish to me, and given that the photo was taken in Arizona, I say Cinnamon Teal.
I'm guessing juvenile Mallard also. Eye stripe looks just like the Mallard but the bill is darker than I recall on the Mallard. Maybe the Mexican Mallard, I think those range into Arizona. Could also be a Mottled or Black Duck as their bills are dark and they have eye stripes though the eye stripes are usually not as pronounced.
