Ring-necked Duck Identification

The Four Keys to ID

  • Size & Shape

    A compact diving duck with a distinctive head shape—a sloping forehead and peaked rear crown. The crown flattens when they are diving. In flight, Ring-necked Ducks appear large-headed with a thin neck and a short, round body.

    Relative Size

    Smaller than a Mallard or Redhead; about the same size as Lesser Scaup.
