Habitat:

  • Found at freshwater marshes, shallow ponds and lakes; coastal bays during winter.
  • Eats mostly fish but also aquatic invertebrates.

Notes:

  • Similar to common merganser, but has a prominent crest on the back of the head (often looks like the bird is having a “bad hair day.”)
  • Female mergansers look similar to male canvasbacks and redheads, but both of those species have black chests.

Be sure to check local regulations for hunting or trapping information on this species.
