The Lesser Scaup, also known as the Little Bluebill or Broadbill, is a diving duck from North America. The Lesser Scaup is very similar in appearance to the Greater Scaup except smaller and not as bulky.

Although the Lesser Scaup has the largest population of diving duck in North America, their population has been declining over the decades. They are currently classed as Least Concern but this may be revised to Near Threatened if the decline continues.
