The blue morph is not more common in the eastern portion of the range. Rather, the epicenter of its breeding range is around Hudson Bay (western side, if I remember correctly) and it is most numerous in the Mississippi Flyway, which is the eastern portion of Lesser Snow Goose. Greater Snow Goose, which breeds farther east and winters on the Atlantic Coast does not appear to have a blue morph, or that is my understanding. Over the last 50 or so years, small numbers of Blue Geese have appeared ever farther west in Arctic breeding colonies, having reached the Wrangell (sp?) colonies around the mid-1980s. That is when small numbers started to appear in w. Washington. Similarly, I don't know the year offhand, but Blue Geese were not always part of the California Snow Goose wintering populations, but started to appear there when Blue Geese expanded into the western Canadian Arctic
