To accomplish this we shall examine: (1) the phase ratios of Hudson Bay Lesser Snow Goose populations in breeding and wintering grounds and the relationship between the two, (2) the effects of differential phase migration and the resulting intermingling of geese from different colonies on mate selection and assortative mating, and (3) the extent to which geese return to their natal colony or emigrate to another.Gene flowBreeding populationsLesser snow geeseArticlehttp://www.aou.org/auk/http://www.jstor.org/stable/4084603
