The Arctic tern is known to make the longest annual migration in the animal kingdom. During its breeding season, it is found far to the north where summer days are long, and it winters far south in the southern hemisphere, where the days are longest during November to February.he Arctic tern is notorious for its long-distance migration between the breeding grounds and the winter quarters in the Southern Ocean.

Peak migrations happen in Ohio between October and November. Flocks of geese fly in a v-shaped group and some will travel non-stop for up to 16 hours to cover over 800 miles. Flocks will also make shorter flights depending on wind patterns and where food is available. During migration, geese can travel as fast as 70 miles per hour with a good tail wind at an altitude of up to 9,000 feet. Geese, like most of our migratory birds, will also migrate during the night.
