Yea, you'll need to put quotations around mexican duck to get the images of them, otherwise you'll get a bunch of great pics like the two spanish rubber ducky's,lol. Basically their like the mottled duck, but instead of black borders on the wings, it's white like the mallard. Do look slightly different than the mottled, but still have the bright yellow bill on the males. Just put some quotation marks around mexican duck and you'll find some pics, range maps, etc. Also, do the same for "mexican mallard" and their will be different pics that'll come up, because that's one of their common names as well
