Here is a description from Audubon:
"Far more vocal than most ducks, and loud melodious calls of flocks can be heard from some distance. It was formerly called "Oldsquaw," not politically correct by any measure, a reference to this "talkative" behavior -- although it is the male of this species that makes most of the noise."
