complete neck ring. Small goose weighing about 5 pounds.Has a high, abrupt forehead that results from enlargement of the supraorbital salt gland in response to consumption of salt water

Cackling Canada Goose
B. c. minima
Small, dark goose with almost duck-like proportions (about the size of a mallard - about 3 pounds). It is darker than other small geese. Has a short, stubby bill and "puffy" head. The neck seems to merge with the breast. It often has a white neck ring, but the ring rarely extends around the back of the neck as it does in the Aleutian Canada Goose. Coastal West Alaska
Leucistic Canada Goose - Photo copyright Tina MacDonald
Branta canadiensis Although not technically a subspecies - the bird in the background of this photo is an interesting leucistic form of Canada Goose. Leucistic forms replace black with grey in some or all of the feathering. At this point, I have no idea what subspecies it is, but it was photographed on Vancouver Island. There is a hint of the broad line under the jaw (grey in this case rather than black), so it may be a Taverner's form. ...
