Did you know that 50% of the planet's Blue-Footed Boobies can be found amidst the Galapagos Islands? These creatures are named for their unusually colored feet and the unusual nature of their being. The Blue-Footed Booby (Sula nebouxii) is a seabird whose diet consists entirely of fish. The color of the feet directly correlates to the health and age of the bird. The brighter the blue, the healthier/younger the animal.
The mating ritual of the Booby is one where the male shows off his feet by dancing for the female as well as "sky-pointing" his bill up to the sky while spreading his wings. It's quite a sight to see.
