WHY BLUE FEET?

Male and female Boobies both have blue feet. However, the males’ feet are of a brighter color, because that makes them more attractive to the opposite sex and gives them a better chance to reproduce, according to the Natureworks website.

The color of the Booby’s feet also reveals the health of the male. The brighter the blue, the more nourished he is, which means he is capable of feeding future offspring. This makes him more attractive to females.
