Blue-footed booby
The blue-footed booby is a specialized fish eater, feeding on small schooling fish such as sardines, anchovies, mackerel, and flying fish. It will also take squid and offal. The blue-footed booby hunts by diving into the ocean after prey, sometimes from a great height, and can also swim underwater in pursuit of its prey. It can hunt singly, in pairs, or in larger flocks. Boobies travel in parties of about 12 to areas of water with large schools of small fish. When the lead bird sees a fish shoal in the water, it will signal to the rest of the group and they will all dive in unison, pointing their bodies down like arrows.
Seabird breeding behavior
Boobies are another group of seabirds known for their mating displays. Brown ("Sula leucogaster"), red-footed ("S. sula") and blue-footed boobies ("S. nebouxii") have at least nine described parts to their mating display. Sky pointing in boobies is similar to albatrosses; in the brown booby, sky pointing is described as a display where the male throws his head backwards, stretches his neck out, and usually gives a whistling vocalization. Parading is a well-known display in boobies as well; in this display, one individual in the pair - usually the male - walks upright, with his tail erect, swaying in an exaggerated manner from side to side while taking small steps. In blue-footed and red-footed boobies, parading also includes lifting and flaunting their brightly colored feet at their prospective partner.
