Greater White-fronted Goose
Anser albifrons
Greater white-fronted geese are 64–81 cm (25–32 in) in length, have a 130–165 cm (51–65 in) wingspan, and weigh 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz). They have bright orange legs and mouse-coloured upper wing coverts. They are smaller than greylag geese. The greater white-fronted goose is larger than and lacks the yellow eye ring of the lesser white-fronted goose, and its white facial blaze does not extend upwards so far as in the lesser.

Snow Goose
Anser caerulescens
The snow goose has two color plumage morphs, white (snow) or gray/blue (blue), thus the common description as "snows" and "blues". White-morph birds are white except for black wing tips, but blue-morph geese have bluish-gray plumage replacing the white except on the head, neck, and tail tip. The immature blue phase is drab or slate-gray with little to no white on the head, neck, or belly. Both snow and blue phases have rose-red feet and legs and pink bills with black tomia ("cutting edges"), giving them a black "grin patch". These colors distinguish the species from white domesticated geese.
