Quck answer
The Blue-footed Booby is a seabird native to the Galapagos Islands. The male of the species performs a unique dance to attract a mate. The dance involves lifting up one foot and then the other, showing off their bright blue feet. The female booby will choose a mate based on the quality of his dance. The blue feet are a sign of health and strength, indicating that the male is a good choice for a mate. This dance has been successful in helping the species reproduce and maintain their population.
Wild Animals
The blue-footed booby, a 3.3-pound wild ocean bird named after a Spanish insult, is slipping into endangered territory. These birds have dark brown wings, signature bright blue feet, and stand about 32 inches in height. They have long bills, cigar-shaped bodies, and narrow, angular wings. The male blue-footed booby performs a high-stepping mating dance to attract females, raising one foot at a time in a move known as sky-pointing, accompanied by horizontally extended wings, raised heads, and a long, hollow-sounding call.
Cerulean Kicks
Despite their unique mating dance, blue-footed boobies hardly make a sound when at sea. Their webbed feet are known as totipalmate feet, and they are as efficient as flippers in the water. Webbed feet also help blue-footed boobies regulate their body temperature. If they become too cold, they can balance on one leg and tuck the other foot into their downy white belly feathers. If they become too hot, the average blue-footed booby cools off by pooping on its own cerulean feet.

A Nickname That Stuck
Early explorers believed that blue-footed boobies were “stupid” and cannibalized the Spanish word “bobo” to create their name. Researchers have studied their habitats, mating rituals, parenting styles, and food preferences, including the penchant of older siblings to peck their younger sibling competitors to death. Half of the population of blue-footed boobies lives in the GalГЎpagos Islands, which are part of Ecuador. These islands were declared a national park in 1959, and Charles Darwin’s visit to the islands in 1835 inspired his evolutionary theory.
The blue-footed booby population is split between two areas, with the majority living in Mexico, Columbia, Ecuador, and Peru along the western coasts of North, Central, and South America. The birds fly over cold oceanic water to find their preferred prey of sardines, anchovies, and small fish. They will also eat squid and use their diving technique to catch prey, even during egg-rearing season. The male and female pairs take turns hunting while one stays behind to incubate the eggs.
Unlike other birds that build elaborate nests to attract mates, blue-footed boobies create nests out of defecation. The nest is built by layering poop in a circular wall around the scrape or depression in rock where the mated pair resides. While this method is successful for the blue-footed booby, it is not without its challenges. Male boobies may destroy the eggs of a new female, other booby species may raid the nest, and older chicks may kill the newly hatched competition.
The blue feet of the booby are a signal of health and potential as a mate, with the intensity of the blue indicating the male’s health. Breeding females choose mates with vivid dark blue feet, as it suggests a greater probability of healthy offspring. However, the blue-footed booby population has been declining due to a decrease in sardine numbers, with fewer than 6,500 adults in the GalГЎpagos Islands in 2018.
When hunting for fresh fish, blue-footed boobies dive from the air at high speeds and use air sacs in their skulls to prevent brain damage from changes in pressure.
