A female common merganser working on lunch. Almost looks like she has Mickey Mouse ears. Mergus merganser Common Mergansers are sometimes called sawbills, fish ducks, or goosanders. The word “merganser” comes from the Latin and roughly translates to “plunging goose”—a good name for this very large and often submerged duck. source - www.allaboutbirds.org/…/Common_Merganser/lifehistory

I'm assuming this is a breeding/aggression display by a red breasted merganser. There were  a number of males chasing each other. The bird on the left lifted its tail, lowered its stomach and lifted its head. This was followed by the merganser stretching his neck as long and tall as it could.
