whales have the longest known migration of any mammal. They travel
10,000-12,000 miles round trip every year between their winter calving
lagoons in the warm waters of Mexico and their summer feeding grounds
in the cold Arctic seas. Thanks to its nearshore migration route,
we can observe the gray along its journey. Journey North reports the
migration and timing from these Observation Posts and more. Click
