Goose (Lesser snow)

The Snow Goose has two colour plumage morphs, snow white or blue gray, thus the common description as "snows" and "blues."

Both types have rose-red feet and legs, and pink bills with black cutting edges, giving them a black "grin patch." 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.

These two colors of geese were once thought to be separate species; since they interbreed and are found together throughout their ranges, they are now considered two color phases of the same species.

When choosing a mate, young birds will most often select a mate that resembles their parents' coloring. If the birds were hatched into a mixed pair, they will mate with either color phase
