The 12 year old gang doubles over with laughter and snorts.

“That’s nothing! Over here this one will be Lake PooPo“.

All right it didn’t happen that way. However, even the most stone-faced traveler will fight a slight curl of the lip, as a tour guide begins speaking of the blue-footed boobies.

How did the blue-footed booby get it’s name?

It is believed that early European explorers named six species of birds boobies after the Spanish word ‘bobo’ meaning stupid.

To those who first saw the birds, they appeared clumsy on land, stumbling over their large, webbed feet. The bird with blue feet, with its willingness to approach people, also seemed foolish to the explorers.

Consequently the unusual blue webbed wonders were labeled with the derogatory, giggle inducing, name.

What are the booby’s blue feet used for?

The large, blue webbed feet are used to cover the 1-3 eggs laid by the female booby. Both the male and female take part in the care of the eggs.

On a side note, the blue-footed booby is monogamous but has the potential to become bigamous. Sounds a bit like humans don’t you think?

Long before covering eggs, the blue feet are used for mating purposes. The male struts and holds up his blue feet to impress the female. The darker the blue of the feet, the more attractive the booby is to prospective girlfriends.

Why are the feet of the booby blue?

One might think the bird has a permanent case of poor circulation. However, with the blue footed booby habitat being on the eastern Pacific coast from California to the Galapagos Islands to Peru, frostbite is unlikely.

It is the blue-footed booby’s diet of fresh fish containing carotenoid pigments that causes the blue color of the feet. A less healthy booby has a lighter blue tone to his or her feet.

Darker feet mean more attractive boobies, which means healthier birds. No wonder Darwin loved studying these islands.

Although the blue-footed booby dance seems comical to humans, studies show that chicks of the blue-footed booby, whose parent has the darkest blue feet, are healthiest.

Thus the showing off of those blue feet, may indicate how well the future parent can feed its young.
