Canadian Geese And Goslings

Every year the same pair of Canadian Geese come to the Methow River and hatch a new set of babies. They teach them to swim in the river and it is such a treat to watch these little chicks grow and develop.
"The Canada Goose (Branta canadensis) is a wild goose with a black head and neck, white patches on the face, and a brownish-gray body. Native to arctic and temperate regions of North America, it is occasionally found in northern Europe, and has been introduced to other temperate regions.
"The Canada Goose was one of the many species described by Carl Linnaeus in his 18th-century work Systema Naturae. It belongs to the Branta genus of geese, which contains species with largely black plumage, distinguishing them from the grey species of the Anser genus. The specific epithet canadensis is a New Latin word meaning "from Canada". According to the Oxford English Dictionary, the first citation for the 'Canada Goose' dates back to 1772. The Canada Goose is often incorrectly referred to as the "Canadian Goose".
The Cackling Goose was originally considered to be the same species or a subspecies of the Canada Goose, but in July 2004 the American Ornithologists' Union's Committee on Classification and Nomenclature split the two into two species, making Cackling Goose into a full species with the scientific name Branta hutchinsii. The British Ornithologists' Union followed suit in June 2005.
The AOU has divided the many subspecies between the two animals. To the present species were assigned:
Atlantic Canada Goose, Branta canadensis canadensis
Interior Canada Goose, Branta canadensis interior
Giant Canada Goose, Branta canadensis maxima
Moffitt's Canada Goose, Branta canadensis moffitti
Vancouver Canada Goose, Branta canadensis fulva
Dusky Canada Goose, Branta canadensis occidentalis
part of "Lesser complex", Branta canadensis parvipes
The distinctions between the two geese have led to confusion and debate among ornithologists. This has been aggravated by the overlap between the small types of Canada Goose and larger types of Cackling Goose. The old "Lesser Canada Goose" was believed to be a partly hybrid population, with the birds named taverneri considered a mixture of minima, occidentalis and parvipes. In addition, it has been determined that the Barnacle Goose is a derivative of the Cackling Goose lineage, whereas the Hawaiian Goose is an insular representative of the Canada Goose." - Wikipedia
