The results showed that Magnificent Frigatebirds (Fregata magnificens), with 9,402 individuals, represented 62% of the total. A single individual of Great Blue Heron (Egretta caerulea), White Ibis (Eudocimus albus), Lesser Yellowlegs (Oceanodroma microsoma), and Lesser Yellowlegs (Tringa flavipes).
