Observation details

On the left. Suspected parvipes subspecies, or "lesser" Canada Goose. Per eBird: "Canada Goose (parvipes) Branta canadensis parvipes, sometimes known as “Lesser” Canada Goose, has long been a controversial taxon. More recently, studies show that size of Canada Geese is driven largely by nutrition as juveniles, raising a legitimate question about whether variation in size is more a result of genetics or nutrition, with birds possibly averaging smaller in the West. Some suggest that parvipes may not be a valid subspecies. Regardless, it seems clear that parvipes is not safely separable from canadensis/interior so we merge it with the latter group. From this point forth, sightings believe to pertain to parvipes should be submitted using the Canada Goose (canadensis Group) Branta canadensis"
