We spent our morning at Cabo Pulmo National Marine Park, an area that was protected at the urging of local people and conservation leaders. Their efforts succeeded! The marine life has recovered from overfishing and now there are healthy heads of coral, large schools of fish, and even top predators – all signs of a healthy ecosystem.

The southern end of the Baja California Peninsula is a winter gathering place for humpback whales, and throughout the day we were observing their activities. Some mothers with calves were by themselves and others were accompanied by one or two adult whales. Groups of three or four whales got quite active at times. We saw many large splashes today as whales breached or energetically slapped their flukes down on the water surface. We were likely watching males compete for the privilege of accompanying a female and possibly mate with her.
