We knew this was a bad idea when Dennis Cheeseman stumped us with this photo montage of Green-winged Teals last week.

He wanted to know what was different about one of the teals, and after we gave up, he said that one of the teal's eyes were closed. So we follishly posted it.

Our apologies. We blame Dennis. Clearly, we've been looking at too many teals for too long.

We do plan to post a genuine photo of a "possible Eurasian Green-winged Teal" tomorrow, along with a Tuesday Teaser involving the ageless Merlin vs. young Peregrine Falcon debate.
