This marine bird can be easily recognizable by its pastel blue feet, which is its sexually trait. They dive at 60 miles per hour for fish from 33 feet to 100 feet sometimes even to 330 feet under the surface. Their nest is on the ground opposite to Red-Footed Boobies whose nest is in trees. Both genders feed the chicks through regurgitation. They can live almost 17 years! The female is larger than the male but the average size of this bird is 32 inches and their weight is 1,5 kilograms. They make polysyllabic shouts and thinly noises.
Males have a interesting mating ritual because they lift their feet up and down in front of the females like an army march. Their feathers are brown and their head and neck are brown with black stripes. The rest of the body except the feet is white. They are one the most popular birds in the Galapagos because they can be seen in almost all the islands in the Galapagos. The most representatives colonies are in Española and North Seymour. You may also find this wonderful bird in Isabela and Fernandina Islands as well as in Daphne Islet.
