Are there any photos of this bird that can be shared?

I ran by the Pellissippi State pond this morning to look for the Greater Scaup reported yesterday. I found the (a) bird, but I'm afraid I'll have to disagree with the ID and call this a Lesser Scaup (at least the bird
that was there this morning).  Some key points...

- head peaks behind the eye with a slight tuft... not rounded with peak
toward the front
- nail on bill is very thin and neat... not broad and messy
- flanks are dark grey... not bright white
- head-on profile is rather thin
- head gloss changed with angle, mostly appearing green but occassionally
purplish

Head gloss can point you in a direction for scaup ID but should not be
used alone because, as in this case, the direction it points you can often
be wrong.
