Migrations: The Triumphant Comeback of the Aleutian Cackling Goose


Migrations: The Triumphant Comeback of the Aleutian Cackling Goose

Aleutian Cackling Geese, which have a slighter build and shorter beak than Canada Geese, build their nests on a chain of islands off the western coast of Alaska. In the 1700s, fur traders introduced foxes to the islands, nearly wiping out the geese. For decades, they were believed to be extinct. But in the 1960s, a biologist discovered about 300 birds nesting on Buldir Island. Habitat protections have allowed their populations to recover.

Cackling Geese may look a lot like Canada Geese, but their slighter build and shorter beaks give them away as a distinct species. And one subspecies in particular has a very special story.
Aleutian Cackling Geese build their nests on a chain of islands off the western coast of Alaska. In the 1700s, fur traders introduced an invasive species of fox to the islands with devastating consequences for the geese. For decades, Aleutian Cackling Geese were believed to be extinct.
But in the 1960s, a biologist discovered a group of around 300 birds nesting on Buldir Island. (pronounced bull (as in cull, not bull) – DEER) The fortuitous discovery allowed conservationists to put these birds on the endangered species list. And this paved the way for federal protections on their Alaskan nesting grounds and their wintering territories in Oregon and California.
Thanks to this habitat conservation, there are now more than 120,000 Aleutian Cackling Geese making the biannual journey between Alaska and the Gulf of Mexico.
