March: Spring Training for Babies, Migration North for Some Adults
In March, mother and baby pairs dominate the lagoons. It's time for males and newly-pregnant females to start their journey north. New moms are doing "spring training" for the babies so they'll be ready for their own first migration in 4 to 6 weeks. They swim with babies against the currents near the mouth of the lagoon. This helps babies build strength and endurance.
