The Blue-footed Booby at the Marietas islands

The Marietas Islands are probably one of the best snorkeling areas in Puerto Vallarta region.  This is also a  protected wildlife sanctuary and marine preserve.

This place is also home to a wide variety of sea life that includes whales, dolphins, giant manta rays and some really rare species of birds, such as the Blue Footed Booby – this bird is said that it can only be found on two places on earth – the Galapagos Islands and here at the Marietas.

The Blue-footed Booby (Sula nebouxii) is a bird in the Sulidae family which comprises ten species of long-winged seabirds. The name booby comes from the Spanish term bobo (which means ‘stupid’ or ‘fool’ or ‘clown’) because the Blue-footed Booby is (like other seabirds) clumsy on land.

This bird is on average 81 cm (32 in) long and weighs 1.5 kg (3.3 lb), with the females slightly larger than the males. It has long pointed wings and a wedge-shaped tail. They have strong, thick necks. The booby’s eyes are placed on either side of their bill and oriented towards the front. They have excellent binocular vision. The Blue-footed Booby’s eyes are yellow. The male has more yellow on its iris than the female. The Blue-footed Booby has permanently closed nostrils made for diving. They breathe through the corners of their mouths. Their feet range from a pale turquoise to a deep aquamarine. Males and younger birds have lighter feet than females do.

The courtship of the Blue-footed Booby consists of the male flaunting his blue feet and dancing to impress the female. During the dance, the male will spread his wings and stamp his feet on the ground.

The brightness of male foot colour is dependent on access to food.  The male’s foot colouration is extremely sensitive, with changes perceivable by female birds within a 48 hour period.

When you visit the Marietas Island you can hear that they make raucous or polysyllabic grunts or shouts and thin whistle noise. The males of the species have been known to throw up their head and whistle at a passing, flying female. Their ritual displays are also a form of communication.

Las Marietas islands and the Blue-footed Booby are part of the amazing things you can discover on your next visit to Puerto Vallarta and we can make your visit a great one, please contact us with all your tours and activities such as this one.
