The hypothesis that cliff nesting is adaptive in this goose species
B) Cliff side nesting confers a higher fitness than does beach nesting. The cliff nesting is more adaptive in the goose species as they are stronger and fitter as compared to the ones that are present in the beach. It is because of the fact that beach ones don’t have to move anywhere but only the cliff ones after hatching needs to move down the beach.
