Occurrence Remarks |
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. |

Event Remarks |
Observed for almost a minute initially swimming directly away from me on a drainage canal at 50-60 meters. The 3 wigeons then took off and made a narrow circle to the north and east, returning to the canal about 60-80 meters away. They were once again viewed for 1-2 minutes until they swam out of view around a corner in the canal to the east. Total viewing time about 3 minutes with Zeiss 10x40 and Selsi Zoom 10x-30x60 binoculars. Partly cloudy, sunny, temp. 30sF, winds N 16 mph. Scattered nearby were several Mallards (Anas platyrhynchos), N. Shovelers (Anas clypeata) and Lesser Scaup (Aythya affinis). |
