Welcome to Journey North's spring monarch migration season! Starts
February 4, 2010
Winter: We begin each year while the monarchs are still at the
overwintering sites, deep in central Mexico. The monarch’s story of
survival during the winter months in Mexico is as spectacular as their
incredible migration. During the first weeks, we’ll look at the
monarch’s winter habitat and their adaptations for survival.
Spring: Get ready to track the migration! The monarchs head north in
March. Find out how to report your sightings and track the migration
on real-time migration maps."
