Blue-Footed Boobies take great pride due to there marvelous feet. During mating rituals, male birds normally show off there feet to prospective mates with a high stepping strut. The Blue-Footed Booby (Sula nebouxii) is a marine bird in the family Sulidae, which includes ten species of long-winged seabirds. Therefore the bluer the feet, the mate considered more attractive.
The booby species are thought to take there name from the Spanish word (bobo), means “stupid, clown, and Fool”. Because the blue-footed booby is clumsy on land regarded as foolish for there apparent fearlessness of humans. Blue feet also indicate the current health condition of a booby, thus, the feet are rapid and honest indicators of a booby’s current level of nourishment. The blue feet are signs that reliably point toward the immunological and health condition of a booby, coloration is favored through sexual selection.
These impressively beautiful feet birds live off the western coasts of central and South America. The Galápagos Islands population includes about half of all breeding pairs of blue-footed boobies. The female bird is somewhat larger then the male and can measure up to 90 cm long with a wingspan of up to 1.5 m. Similar to other boobies the blue-foot nest on land at night.
Blue-Footed Booby are flew in search of seafood, may fly far out to sea keeping an eye for schools of small fish in cooperative groups such as sardines, anchovies, mackerel, and flying fish. These seabirds are exceptional divers, fold there long wings back around there streamlined bodies and plunge into the water from as high as 24 meters and swimming underwater in search of it’s prey. Even, they can also dive from a sitting position on the water’s surface. These birds hit the water around 97 km/h and have ability to go to depths of 25 meters below the water surface.
Both sexes start breeding between 1 to 6 years. The blue-footed booby usually lays 1-3 eggs at a time, and they’re very caring to there chicks, use there webbed feet to cover and keep them warm. Both male and female take turns incubating the eggs, and the incubation period is falling between 41–45 days. Both male and female birds share parental responsibilities.
The male will provide food for the young and chicks feed off the regurgitated fish in the adult’s mouth. The boobies’ natural breeding habitats are tropical and subtropical islands of Pacific Ocean. The blue-footed booby wings are brown color, neck and head are light brown with white streaks, belly and underside full white plumage. The boobies’ are having distinctive yellow color eyes with excellent binocular vision.
Blue-Footed Booby hunts singly, in pairs, or in larger flocks. Blue-footed boobies make raucous or polysyllabic grunts or shout and thin whistling noises and there ritual displays are also a form of communication, hence mates can identify each other by there calls.
The Blue-Footed Booby population appears to having trouble breeding and thus is slowly declining. The decline is feared to be long-term, but annual data collection is needed for a firm conclusion that this is not a normal fluctuation. Food problems may be the cause of an observed failure of the birds to even try to breed.
