Nazca boobies, formerly known as masked booby and recently renamed, are the largest of the three booby species found in the Galápagos. Like the blue-foot and red-foot boobies they feed on fish which they capture by plunge-diving, singly or in small groups. While blue-foots are inshore feeders and red-foots hunt well out to sea, the Nazca Booby fills the niche in between these extremes, feeding farther offshore than the blue-foots, but not as far as the red-foots. As a species the Nazca Booby breeds on an annual cycle, but each island’s nesting population breeds at a different time. We were fortunate in that the Española population, so close to the trail, was well into their breeding season so we got to see active courtship ritual, seen here.
