The documentation form by Randall Pinkston is the earliest and the one that forms the basis of this record. | Elimination of similar species: Obvious differences from American Wigeon include the American's dark (green) face mask, white forehead and crown ("baldpate"), as well as those other differences discussed above. Female American has finely mottled grayish head and brownish sides, lacks striking patterns on wings and hindparts. Redhead (Aythya americana) has 'pochard' gestalt with darker brick-red vs. cinnamon-buff head, head more rounded in profile, tricolored bill broad and stout. Also has relatively plain wing with gray coverts and pale gray remiges. Canvasback (Aythya valisineria) of either sex safely separable on the basis of head and bill in profile. Again, male's head is dark brick-red, back and sides whitish, lacks bold wing pattern. Female mergansers easily separable on the basis of bill alone. | The original documentation form event occurred around 11:00:00.
