The calm, shallow warm waters of the Chiriqui Gulf seem like the perfect place for humpback whale calves to be born. We often see moms and babies lazing at the surface of the water or traveling slowly, everything peaceful and calm. However, this year we have seen several "competitive groups" that include a small calf. Competetive groups are when a group of males are competing to mate with a female, and involve agressive behavior between the males. It's a bit alarming to see very small calves amongst fully grown adults who are hurling their bodies at each other.
