Frigatebirds (Fregata minor)
The largest and most notable birds on the islands are the cleptoparasitic great and magnificent frigate birds. Males boast an inflatable red pouch below the beak during mating season—sure to catch the eye of any female. Crowning its attributes, a frigate's wingspan can reach 2.3m, giving it the largest wingspan-to-weight ratio of any existing bird. Mating occurs on San Cristobal and Genovesa from March to April and on North Seymour throughout the year.
