Ring-billed Gull Migration, page 2

Winter Range: In October and November, gulls mass for fall migration. Most of the Great Lakes populations fly eastward to the Atlantic coast, spending winters along the coast from Maine to Mexico. Research shows that gulls as young as two days old show a preference for magnetic bearings that would take them in the appropriate direction for their fall migration. Each year, however, a fair number of Ring-billed Gulls remain in the southern Great Lakes area and on interior lakes and rivers where food and ice-free water are available.
