Blue Feet Attract Mate

The blue-footed booby has some attractive feet — at least to its female counterpart. The male blue-footed booby takes pride in its blue feet because they are a big part of its mating ritual. Apart from their vivacious color — the bluer the feet the more attractive the mate — they show off their feet in a high-stepping walk to attract females. However, these feet aren’t just for show; they can also be used to cover the up their chicks and keep them warm.
