Also along the eastern coastline of Punta Suárez are colonies of blue-footed boobies. With a wingspan averaging five feet, they are the second largest booby endemic to the Galápagos. The mating season of these monogamous seabirds peaks between June and August. The female typically lays two eggs on the ground about five days apart. The parents take turns incubating the eggs with their bright blue feet for about 45 days. Then the chicks are protected and fed for about two months. There are more than 25,000 breeding pairs of blue-footed boobies living in the Galápagos Islands.
