|Ring-necked Duck (Aythya collaris), Gilbert Water Ranch, Feb. 18, 2012.|
Countless times when I am out birding I'll hear someone say "I don't know why they call them Ring-necked Ducks when the ring is around their bill". Sometimes I'll offer an explanation, but most often I just let them continue to wonder. Who really wants to admit that back in the day birders killed the ducks and then ID'd them. So, does the above photo reveal the infamous hidden ring of the Ring-necked Duck, or is it just an optical illusion?
