I'm quite sure that there are two birds. I like Ted's photo as an
intergrade as the wing stripe is fairly strong, more so than on an
American. I have been able to see the Common (Eurasian) Teal from both
sides and it has no hint of a side spur and the wing stripe is quite
prominent. Other features of this bird I've noted are the more defined thin
facial stripes and a blue/purple cast to the iridescent eye-stripe vs
blue/green of nearby American. Keep in mind that on a Eurasian the scaps or
gray flank feathers can partially obscure the white wing stripe, making it
appear reduced at a distance.
