winter, California gray whales (Eschrichtius robustus) migrate
southward along the western coastline of North America,
leaving their summer feeding grounds in Canada and Alaska,
traveling 5,000 miles to the warm, protected waters in the
lagoons of Baja California, Mexico. Pregnant females are
believed to leave first and sometimes give birth to their
calves along the way. (On 1999, one injured calf was rescued
from the ocean near Southern California. She was rehabilitated
at Sea World in San Diego and released to join the following
year's migration.) Once the whales arrive inside the lagoons,
the calves benefit from the warmth, salinity and safety
of the shallow waters.
