This month's quiz ducks – and ducks they are, as evidenced by the patterned flank feathers – are, by those same patterned flank feathers, almost certainly dabbling ducks. Of course, as the left one is inverted into the water in the manner of a dabbling duck foraging, let's go with it. Once we get to thinking about the various dabbler options, we might notice our birds' green specula and opine, "Yow, this one's easy: Green-winged Teal!"

Unfortunately, it's not that easy, as there are features that do not match an ID of Green-winged Teal. In the identification process, not only do we need to determine what field characters a bird has that point to a given ID, we also need to determine what field characters that a bird possesses that rule out other species. In that vein, the features that argue against an ID of Green-winged Teal are many and include, particularly, the whitish tail, the lack of a yellowish patch at the base of the tail, and the orange legs… er… leg. This, then, is the reason behind the use of this picture in the quiz: A surprising number of birders do not know that all ABA-area teal have green specula, as do both wigeons and Northern Pintail. “Green-winged Teal” is not a very ID-helpful name.

The left bird shows just a bit of its left leg and that bit is bright orange; Green-winged Teal (both Old World and New World) sport dark legs, as does Garganey. Blue-winged and Cinnamon teal have pale legs, but they do not usually get this bright. Baikal Teal have gray or grayish-yellow legs. Additionally, most of the tail of the left bird is white, a feature at odds with nearly all dabbling ducks. Mallards have bright orange legs and white tails, but their specula are blue. However, iridescent colors are tricky – could the green just be a trick of the light with a structural color? While certainly possible, the trailing edge of the speculum visible on the right bird rules Mallard out – it lacks the wide, white terminal band of that species.

What's left is the biggest teal of them all. I took this picture of two female Northern Shovelers at Cape May Point State Park, Cape May Co., NJ, on 13 November 2010.
