Our duck in last week's quiz was a drake (or male) Lesser Scaup, Aythya affinis. Both the Greater Scaup and Ring-necked Duck can be easily confused with this species. First thing I look for when deciding between Lesser or Greater is head shape while, with the Ring-necked, I look for the white edges on the bill and (to a lesser extent) the coloration of the flanks or sides of the body. Most field guides point out these important differences. Good luck with this week's bird and have a great week birding!
