December: Courting, Mating and Migrating
In December, whales may be seen courting and mating. Many whales are on the migration route. Some may be arriving in the lagoons of Mexico. Pregnant females are in a hurry to get to Mexico, so they arrive first. Other whales might take their time getting there. The breeding and birthing season is underway!
