Overview
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-grey 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. The colors are not as bright on the feet, legs, and bill of immature birds. The head can be stained rusty-brown from minerals in the soil where they feed. They are very vocal and can often be heard from more than a mile away.

Habitat
Breeds in tundra. Winters in lakes, marshes, and agricultural fields.
Diet
Traditionally, snow geese wintered in coastal marsh areas where they used their short but very strong bills to dig up the roots of marsh grasses for food. The first transition from the coastal marshes and feeding on roots was to rice fields in the majority of the southern United States, where the geese could graze on weeds and eat the grain left behind by combines. A decade later the geese have mastered field feeding and have diversified into all waste grains left over in farm fields through-out the North American continent. The snow geese have also begun to graze in fall-seeded grain fields, especially winter wheat where they wreak havoc on fresh sprouting or matured fields. Snow Geese now feed in grain fields as soon as they reach the prairies in September, and they continue to use agricultural fields until they leave the prairies in April and May on their way to Arctic breeding areas.
Behavior
Snow geese breed from late May to mid-August, but they leave their nesting areas and spend more than half the year on their migration to-and-from warmer wintering areas. During spring migration (the reverse migration), large flocks of snow geese fly very high and migrate in large numbers along narrow corridors, more than 3,000 mi (4,800 km) from traditional wintering areas to the tundra.
Hunting
Typically hunted with a 12 ga shot. Shot size #2-4 is sufficient. Effectively hunted with decoys and calling.
