The Red-footed Booby (*Sula sula*) is the smallest of the three booby species found in the Galápagos, but also the most numerous, with a large breeding colony on Genovesa Island known as "Bird Island" or "Darwin Bay," where thousands nest in low trees and shrubs rather than on the ground like their masked and Nazca relatives. True to their name, they have brightly colored red-orange feet, which stand out against plumage that comes in two distinct color morphs — a white morph with black flight feathers, and a more common brown morph — along with a pale blue-grey bill and pink-and-blue facial skin. Unlike other boobies, they're the only species in the family that regularly perches in trees and builds nests off the ground, using their strong grip to hold onto branches, and they typically lay just a single egg per breeding attempt rather than the two eggs common to other booby species. Excellent long-distance foragers, they can fly far out to sea and dive at high speed to catch flying fish and squid, sometimes even foraging at night by using bioluminescence to spot prey, and thanks to healthy, stable colonies across the islands, they remain classified as a species of least concern.
