If one dies, the other may find a new mate. the genera Anser and Branta), the Canada goose is on average the largest living species, although some other species that are geese in name, if not of close relation to these genera, are on average heavier such as the spur-winged goose and Cape Barren goose. As you can likely tell, the cackling goose looks remarkably similar to the Canada goose. Taxonomy conform IOC World Bird List. [34], As the annual summer molt also takes place during the breeding season, the adults lose their flight feathers for 20–40 days, regaining flight about the same time as their goslings start to fly.[35].

The Canada goose (Branta canadensis) is a large wild goose species with a black head and neck, white cheeks, white under its chin, and a brown body. The evidence suggests that both of these cacklers were of the minima subspecies. Prior exposure to other viruses may result in some resistance to H5N1.[58].
