Visitor Pictures: gregjw knows how the penguin biologists tell the difference between the male and female penguins!
Apparently it’s difficult to quickly determine the gender of penguins, so caretakers look at the penguins’ DNA to determine which are male and which are female. Once a penguin’s gender is determined, he or she is given a flipper band for future reference. At the New England Aquarium, the males have their bands placed on their left flippers, while the females have bands on their right flippers. The easiest way to remember the system? “The women are always right.”
It seems the male African penguin in this picture should have remembered that, because the female penguin looks to be having none of his shenanigans today.
