Ouzel ain't a word and I ain't gonna use it...

Water ouzel, or American dipper, a bird that "flies" under whitewater.

I went rafting the Green River and mentioned that I thought Dippers were also known as Water Ouzels...even the ornithologist who was with us had never heard that name...today, I found evidence on the net that Ouzel is a word, and another name for water dippers... :)
