It may be 3 months before the young first fly, and 5 months before. Females lay one chalky blue egg in a stick nest, which is incubated by both parents for 44-46 days. The nests are usually located in a tree or bush, but rarely boobies may nest on the ground. The Blue-footed Booby makes no nest, but lays its eggs on bare ground. The booby’s plumage is predominantly brown, while its head and neck display a lighter shade of cream or white. Red-footed boobies nest in large colonies, placing their nests not far from each other.Although the famous mating display might seem comical to humans, the display of foot color provides critical information on a bird’s health and ability to provide for young. One study looked at foot color in relation to the health of young chicks and found that healthiest chicks tended to have fathers with intensely blue feet-possibly an indication of the father’s ability to keep himself well fed. Boobies with bluer feet appear to have more success in finding a mate than birds with duller blue feet. These seabirds have a unique appearance, with their long, slender bills, white bodies, and blue feet. The color of their feet is a result of pigments in their skin. The blue color of Blue-footed Booby’s feet varies in its intensity. Blue-footed Booby seabirds are found more often along the coasts of Mexico, Central America, and South America, particularly in the area of the Galapagos Islands.They also flutter the skin of their throats (the gular pouch) by rapidly vibrating bones in their throat, which creates evaporative cooling through the open mouth. The largest booby species are the three gannets white, goose-sized birds with black flight feathers. Some birders also refer to them as Sulids, and all are big seabirds with long, pointed wings, wedge-shaped tails, and large, wedge-shaped beaks. The other part of the nameboobyis reportedly taken from the Spanish for stupid, (bobo) and refers to these birds’ tameness around people. Boobies are ten bird species that make up the Sulidae bird family. To stay cool in very hot environments, Blue-footed Boobies sometimes defecate on their feet (a behavior called urohydrosis). The Blue-footed Booby has captivated the human imagination for centuries with its mating display, in which its vivid baby-blue feet play a key role.
