Photographer's Note

Note: The following text comes from Galapagos Conservation Trust website: "Blue-footed boobies are large, distinctive birds, found along the Eastern Pacific coastline where they often nest on small islands with rocky coasts. Their name comes from the Spanish word bobo, meaning foolish or clown referring to their clumsy movement on land. Their plumage is brown on top, with a white rump and black tail, whilst their underparts are white. The most distinctive characteristic of the blue-footed booby is its large blue feet, which play an important role in courtship. Females are thought to select males with brighter feet, as they are an indicator of his overall condition and thus the quality of his genes. Females tend to be larger than males, and have darker blue feet.

Despite their clumsiness on land, boobies are extremely agile in the air. At dawn, they take to the sky in search of schools of small fish such as anchovies and sardines, often foraging in large groups of up to 200 birds. Once the prey has been spotted, the booby folds back its wings, giving it a more streamlined shape, and plunges into the water. Dives may occur from over 20 metres above the water, and the bird hits the water at speeds up to 60 mph, snapping up fish in its serrated beak.

The mating season for blue-footed boobies occurs between June and August. Mating is preceded by an elaborate courtship ritual, which begins with the male presenting the female with a small stick or stone. He then tips his beak, tail, and wing tips to the sky, whistles, and marches around the female with a high-stepping motion, showing off his feet. Once a match is made, the pair will often remain together for life. The female lays two to three eggs, which both parents take turns to incubate whilst the other keeps watch for predators. Boobies lack a brood patch, instead using their large feet to keep the eggs warm. Eggs hatch after approximately 45 days, and the chicks are fed on regurgitated fish by both parents. Young boobies will stay with their parents for about two months"
