The Blue-Footed Booby
The blue-footed booby isn’t only known for its ridiculous name but also for the very bright coloration on its feet. Its name comes from the Spanish word “bobo,” which means stupid due to how tame the birds can be around people. Its feet and display rituals are also a marvel to behold. The blue color can vary with intensity, and it’s the males with the brightest feet tend to get mates. In examining the chicks of these males, the healthiest babies tended to have fathers that had the most brilliant blue feet as well.
