GREATER SCAUP, TOLLGATE POND, HAMILTON, ON

   We can ID these ducks as Greater Scaups, rather than Lesser Scaups as follows:
  • Rounded head.  The Lesser Scaup has a corner at the rear of the head, while the Greater Scaup has a more rounded head.
  • Prominent black nail on bill.  This can be seen in the first photo.
