Cackling Goose


IUCN Conservation Status: Least Concern

The newly recognized Cackling Goose is a smaller version of the Canada Goose. Formerly considered the smallest subspecies of one variable species, recent work on genetic differences found the four smallest forms to be very different. These four races are now recognized as a full species: the Cackling Goose. It breeds farther northward and westward than does the Canada Goose.

Cool Facts

  • The Cackling Goose was long considered just a small race of the Canada Goose. The smallest four of the eleven recognized races were recently determined to be distinct enough to be their own species. Cackling Goose includes the races known as Taverner's, Richardson's, Aleutian, and Cackling geese. Confusingly, the "Lesser Canada Goose" is still a race of the Canada Goose.
  • Although most Cackling Geese nest along ponds and streams in the tundra, the Aleutian form nests on south-facing turf slopes above rocky, cliff-bound shorelines. The Richardson's form can nest in colonies of several hundred pairs on cliffs and steep rock slopes.
  • The smallest form of the Cackling Goose is only a quarter the size of the "Giant Canada Goose" subspecies.



Breeds in coastal marshes, along tundra ponds and streams, and steep turf slopes above rocky shores.



Entirely herbivorous. Eats variety of plant species and parts, especially grasses, sedges, grain, and berries.

Least Concern

Aleutian Cackling Goose was protected under the original Endangered Species Act in 1973, but was removed from the list in 2001. Other forms increasing, but still below long-term averages.
